										<content:encoded><![CDATA[<p class="p1">You never really think too much about time unless you are late, planning an event, or even setting your alarm clock. It generally is understood that it exists and we, as a society, keep track of it through clocks, watches, conversations, and agendas.</p>
<p class="p1">When you get accepted to sail on the JOIDES Resolution, you understand that you are going to work 12 hours under the time zone the ship is chosen to follow. However, time starts to become more and more relative the longer you are on the ship.</p>
<p class="p1">The first moment where you notice that the way you interact with time is different to the way you interact with it on land is when the only greeting you hear is “Good morning!”. The ship operates 24/7, which means that there are 4 different shifts for the 118 crew members to work. Your morning can be midnight, 6pm, 6am, or midday, and thus anytime you see someone for the first time that day you greet them with good morning.</p>
<figure id="attachment_40926" aria-describedby="caption-attachment-40926" style="width: 225px" class="wp-caption alignnone"><img fetchpriority="high" decoding="async" class="size-medium wp-image-40926" src="https://joidesresolution.org/wp-content/uploads/2024/03/IMG_1801-225x300.jpg" alt="" width="225" height="300" srcset="https://joidesresolution.org/wp-content/uploads/2024/03/IMG_1801-225x300.jpg 225w, https://joidesresolution.org/wp-content/uploads/2024/03/IMG_1801-768x1024.jpg 768w, https://joidesresolution.org/wp-content/uploads/2024/03/IMG_1801-1152x1536.jpg 1152w, https://joidesresolution.org/wp-content/uploads/2024/03/IMG_1801-1536x2048.jpg 1536w, https://joidesresolution.org/wp-content/uploads/2024/03/IMG_1801-scaled.jpg 1920w" sizes="(max-width: 225px) 100vw, 225px" /><figcaption id="caption-attachment-40926" class="wp-caption-text">Chang enjoying his cup of tea after waking up for his 6pm to 6am shift.</figcaption></figure>
<p class="p1">This is not initially detrimental to your concept of time, but compound it with the fact that your 12 hour shift isn’t wholly during daylight hours. While the midnight to midday or midday to midnight both are split almost in half by daytime and night time, the 6pm to 6am does not experience that. The 6pm to 6am shift wakes up to night as their morning, and works through their shift as it spans across two calendar days. Their today is tomorrow as well, and they go to bed after sunrise making their tomorrow start tonight. The most similar to land time is the 6am to 6pm shift, but very rarely do more than 4 people get to work that shift, but even then time is still a little wonky since you still interact with onshore colleagues that are not in the same timezone as you.</p>

<figure id="attachment_40928" aria-describedby="caption-attachment-40928" style="width: 1024px" class="wp-caption alignnone"><img decoding="async" class="wp-image-40928 size-large" src="https://joidesresolution.org/wp-content/uploads/2024/03/Screenshot-2024-03-23-at-22.55.44-1024x138.png" alt="" width="1024" height="138" srcset="https://joidesresolution.org/wp-content/uploads/2024/03/Screenshot-2024-03-23-at-22.55.44-1024x138.png 1024w, https://joidesresolution.org/wp-content/uploads/2024/03/Screenshot-2024-03-23-at-22.55.44-300x40.png 300w, https://joidesresolution.org/wp-content/uploads/2024/03/Screenshot-2024-03-23-at-22.55.44-768x103.png 768w, https://joidesresolution.org/wp-content/uploads/2024/03/Screenshot-2024-03-23-at-22.55.44.png 1444w" sizes="(max-width: 1024px) 100vw, 1024px" /><figcaption id="caption-attachment-40928" class="wp-caption-text">A table to show how four differen&#8217;t people&#8217;s shifts overlap. The grey indicates when the person is off shift, while their designated color shows when they are on shift. The time at the top is in military time.</figcaption></figure>
<p class="p1">Timezones become a regular part of how you think because you have onshore family, friends, and work colleagues that are in a different time zone from you. Plus, shipboard computers are always at UTC but shipboard clocks and watches are on the current timezone we are sailing in.<span class="Apple-converted-space"> </span>For instance, we are sailing in the Italian time zone, UTC + 1. Add in the fact that as the outreach officer I have to schedule ship to shore broadcasts for a global audience, I have to discern what time zone the 3pm that someone wants to book an appointment is in compared to mine. The mental gymnastics become especially interesting when the time zone differences leads to it being my tomorrow but their evening.<span class="Apple-converted-space">  </span>For instance, 7 pm EST for someone in New York, USA on March 22 is the ship’s 12am March 23.</p>
<figure id="attachment_40925" aria-describedby="caption-attachment-40925" style="width: 225px" class="wp-caption alignnone"><img decoding="async" class="size-medium wp-image-40925" src="https://joidesresolution.org/wp-content/uploads/2024/03/IMG_1790-225x300.jpg" alt="" width="225" height="300" srcset="https://joidesresolution.org/wp-content/uploads/2024/03/IMG_1790-225x300.jpg 225w, https://joidesresolution.org/wp-content/uploads/2024/03/IMG_1790-768x1024.jpg 768w, https://joidesresolution.org/wp-content/uploads/2024/03/IMG_1790-1152x1536.jpg 1152w, https://joidesresolution.org/wp-content/uploads/2024/03/IMG_1790-1536x2048.jpg 1536w, https://joidesresolution.org/wp-content/uploads/2024/03/IMG_1790-scaled.jpg 1920w" sizes="(max-width: 225px) 100vw, 225px" /><figcaption id="caption-attachment-40925" class="wp-caption-text">Tessa looking at the world clocks on her phone trying to determine if the time zones align with her waking hours for a ship to shore broadcast.</figcaption></figure>
<p class="p1">As our shifts extend into different days, being able to talk about what day it is becomes even harder. A lot of times we just say “two days from now” or “ when you wake up next” instead of identifying the actual day as Monday or Friday. This very likely is heightened by the fact that a lot of our day is monotonous, once described as ground hog day. Wake up &#8211; eat &#8211; work- eat- work &#8211; eat- social time- sleep- REPEAT. Give or take the sunset or sunrise.</p>
<figure id="attachment_40929" aria-describedby="caption-attachment-40929" style="width: 300px" class="wp-caption alignnone"><img loading="lazy" decoding="async" class="size-medium wp-image-40929" src="https://joidesresolution.org/wp-content/uploads/2024/03/Screenshot-2024-03-24-at-15.37.08-300x297.png" alt="" width="300" height="297" srcset="https://joidesresolution.org/wp-content/uploads/2024/03/Screenshot-2024-03-24-at-15.37.08-300x297.png 300w, https://joidesresolution.org/wp-content/uploads/2024/03/Screenshot-2024-03-24-at-15.37.08-1024x1012.png 1024w, https://joidesresolution.org/wp-content/uploads/2024/03/Screenshot-2024-03-24-at-15.37.08-150x150.png 150w, https://joidesresolution.org/wp-content/uploads/2024/03/Screenshot-2024-03-24-at-15.37.08-768x759.png 768w, https://joidesresolution.org/wp-content/uploads/2024/03/Screenshot-2024-03-24-at-15.37.08.png 1068w" sizes="auto, (max-width: 300px) 100vw, 300px" /><figcaption id="caption-attachment-40929" class="wp-caption-text">The 3rd mate enjoying the sunshine and a book before he heads to bed</figcaption></figure>
<p class="p1">I am not the only one that experiences time as a weird social construct when on the ship, it is a shared by my crew members.</p>
<p class="p1">Brandon, one of the physical properties specialists on board, mentioned that the only way he knows it was the weekend was due to the fact that he gets less emails than usual. Tori, one of the Paleomagnetists on board, pointed out that the language we use to identify meal time is even lost. When trying to invite someone to take a break for lunch, it could be your first meal but their second meal and the kitchen’s third meal cooked that day, and thus you are left to say &#8220;Meal time?&#8221;. Don’t forget that the only crew members that get breakfast food like eggs or oatmeal<span class="Apple-converted-space">  </span>for their first meal is the 6am to 6pm shift, which is not ideal for Brandon who really enjoys some bacon in the morning. So you can&#8217;t really use the kind of food you have to develop an understanding of time passing.</p>
<p class="p1">As much as time, when on the ship, is endless or a black hole or far from reality, it is cherished by the crew members. We create unique bonds of friendship, and find ways to provide variability as the days drone on. During expedition 402 we had a hot wing competition, wellness wednesday movie night, a talent show, and more. We make do with time on the ship, even if we are confused about what day or time it is.</p>

										<content:encoded><![CDATA[<p><iframe loading="lazy" title="What do Soda Cans, Resistivity, and Drilling have to do with each other?" width="1200" height="675" src="https://www.youtube.com/embed/XSTE3ngxUoA?feature=oembed" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe></p>
<p><em>&#8220;Turns out soda cans and core liners have the same diameter&#8221;</em> That was the start of a very interesting, but useful DIY experiment out here on the Tyrrhenian Sea.</p>
<p>Watch the movie to see the process of testing the soda can meter and/or read below for a quick summary.</p>
<p>Clay Furman is the Schlumberger Logging Engineer in charge of helping the science crew with <a href="https://www.youtube.com/watch?v=0qjOKKj35-k">downhole logging.</a> When the borehole is finished being drilled for core collection, scientists will want to take measurements of the actual cored geological formations in the borehole. They can correlate that data to the data collected in the core as a way to close any gaps of information. Clay who is an expert in how to build, use, and run the logging tools, is contracted out from Schlumberger so there is only one of him on board trained to use the tools. One of the tools he deploys reads the electrical resistivity geological formations through the borehole walls. Electrical Resistivity is measuring the materials resistance to an electrical current moving through it. Plus, resistivity plays an useful role in identifying both the chemical and minerology make up of the surrounding fluids and geological materials. This information can be the building blocks to answering questions about historical climates and environments. These kinds of details are fascinating to Philippe Pezard, the downhole logging specialist, who spends time reading the output of the 4+ logging tools used during expedition.</p>
<figure id="attachment_40894" aria-describedby="caption-attachment-40894" style="width: 300px" class="wp-caption alignnone"><img loading="lazy" decoding="async" class="size-medium wp-image-40894" src="https://joidesresolution.org/wp-content/uploads/2024/03/eec6c18f-8f2c-4e0a-b840-aeb0749b0c29-300x225.jpg" alt="" width="300" height="225" srcset="https://joidesresolution.org/wp-content/uploads/2024/03/eec6c18f-8f2c-4e0a-b840-aeb0749b0c29-300x225.jpg 300w, https://joidesresolution.org/wp-content/uploads/2024/03/eec6c18f-8f2c-4e0a-b840-aeb0749b0c29-1024x768.jpg 1024w, https://joidesresolution.org/wp-content/uploads/2024/03/eec6c18f-8f2c-4e0a-b840-aeb0749b0c29-768x576.jpg 768w, https://joidesresolution.org/wp-content/uploads/2024/03/eec6c18f-8f2c-4e0a-b840-aeb0749b0c29-1536x1152.jpg 1536w, https://joidesresolution.org/wp-content/uploads/2024/03/eec6c18f-8f2c-4e0a-b840-aeb0749b0c29.jpg 2048w" sizes="auto, (max-width: 300px) 100vw, 300px" /><figcaption id="caption-attachment-40894" class="wp-caption-text">Philippe Pezard presenting his findings in a meeting with the science crew.</figcaption></figure>
<p>&nbsp;</p>
<p>After logging one of our drilling sites, Philippe noticed that in the logging results there was an area of higher resistivity than the rest of the borehole. This was interesting because the cores did not have a similar increase. So it begs the question, what made it get that high?</p>
<p>&nbsp;</p>
<p><img loading="lazy" decoding="async" class="alignnone size-medium wp-image-40893" src="https://joidesresolution.org/wp-content/uploads/2024/03/IMG_5080-1-300x260.jpeg" alt="" width="300" height="260" srcset="https://joidesresolution.org/wp-content/uploads/2024/03/IMG_5080-1-300x260.jpeg 300w, https://joidesresolution.org/wp-content/uploads/2024/03/IMG_5080-1-1024x889.jpeg 1024w, https://joidesresolution.org/wp-content/uploads/2024/03/IMG_5080-1-768x667.jpeg 768w, https://joidesresolution.org/wp-content/uploads/2024/03/IMG_5080-1-1536x1333.jpeg 1536w, https://joidesresolution.org/wp-content/uploads/2024/03/IMG_5080-1.jpeg 1992w" sizes="auto, (max-width: 300px) 100vw, 300px" /></p>
<p>One notable fact is that we use drilling fluid when coring. During drilling operations we use drilling fluids to help flush out the borehole of cuttings that get generated as we core. But if the cuttings aren&#8217;t flushing out of the borehole as fast as we need, we will switch to drilling mud which is seawater mixed in with a high viscosity mud. Soon after seeing the results, Philippe decided to determine the resistivity of the drilling mud and enlisted the help of Clay. It was theorized that the drilling mud was giving off that resistivity measurement rather than that of seawater.</p>
<p>To clarify, drilling fluid is used to flush out the drilling cuttings throughout the process of drilling to avoid the drill pipe from getting stuck during operations. Since the resistivity logging tool sends an electrical current out from the tool into the borehole wall and back, the resistivity of any material both liquid and solid will be recorded. If the drilling fluid was not flushed out before the logging tools were sent down, we would also be recording that drilling fluid resistivity.</p>
<p>To determine if the theory was correct, Clay built a DIY resistivity meter out of soda cans. Then took the data back to Philippe to compare it to the results shown above. Turns out, the spike in resistivity was due to a certain amount of drilling mud that got stuck in that part of the borehole!</p>

										<content:encoded><![CDATA[<p>I have had the privilege to sail twice on the <em>JOIDES Resolution</em>, with this being my second cruise, <a href="https://joidesresolution.org/expedition/tyrrehenian-continent-ocean-transition/">Expedition 402 Tyrrhenian Continent-Ocean Transition</a>. The first time was with Expedition 393: South Atlantic Transect II. We aimed to study the age of the oceanic crust as we moved away from the mid-Atlantic ridge toward South America. You can see the expedition summary<a href="https://joidesresolution.org/expedition/393/"> here</a>.</p>
<figure id="attachment_40821" aria-describedby="caption-attachment-40821" style="width: 225px" class="wp-caption alignnone"><img loading="lazy" decoding="async" class="size-medium wp-image-40821" src="https://joidesresolution.org/wp-content/uploads/2024/02/5dc25530-8a39-4264-8f9c-48bd9593a6c3-2-225x300.jpg" alt="" width="225" height="300" srcset="https://joidesresolution.org/wp-content/uploads/2024/02/5dc25530-8a39-4264-8f9c-48bd9593a6c3-2-225x300.jpg 225w, https://joidesresolution.org/wp-content/uploads/2024/02/5dc25530-8a39-4264-8f9c-48bd9593a6c3-2.jpg 768w" sizes="auto, (max-width: 225px) 100vw, 225px" /><figcaption id="caption-attachment-40821" class="wp-caption-text">Tessa Peixoto on steel beach in front of a sunrise during Expedition 393</figcaption></figure>
<p>At the time I had very little understanding of rocks and sediment besides what my oceanography class in college provided me. Most of my academic career was focused on the biology of organisms, so when I thought of rocks I thought of how they provided shelter and structure for the living things that I studied. For instance, rocks provided a hard surface for corals and algae to root themselves and sediment provided hiding spots for bottom dwelling fish. After a few days on Expedition 393, I learned that rocks and sediment can hold the history of our atmosphere, the history of our oceans, and the history of catastrophic events (big or small).</p>
<p>The rocks and sediment on both expeditions have been extraordinarily different. I cannot say that I have seen a similar core between the two, which makes sense because we are in drastically different areas. But again, I had the genuine thought, what could be different about the seafloor from one place to another.</p>

Each core was taken on different expeditions.</figcaption></figure>
<p>Each expedition has different goals, and different operation expectations, however the methods we use to drill, make thin sections, make p-wave velocity measurements, and more  tends to be relatively the same give or take some modifications. For example, thin sections can only be done by taking a small piece of hard rock, cut a thing slice from the top, then polish it down to the thickness of a hair strand. That process does not change because we found a rock in a different ocean. As someone who was returning to the <em>JOIDES Resolution</em>, I envisioned seeing similar gray rocks with some dark grays and browns, I envisioned seeing sediment that followed the color range of chocolates in a chocolatier shop. I figured I was going to be learning about the ocean floor from a different perspective guided by the different expedition objectives. Immediately, I was very wrong and it was thrilling. As Phillipe Pezard, our Downhole specialist, said on one of our first days: “I am a kid in a candy shop”. The ship is a candy shop and the scientists are the local kids who just got their weekly allowance.</p>
<p>Sediment in the Tyrrhenian Sea did not look the same as that of in the South Atlantic, nor did it seem to act the same way when we drilled into the seafloor in both locations.</p>

<p>As someone who does not immerse themselves in geology every day, I still was able to follow the science party as they explained their research goals and expectations from the <a href="http://publications.iodp.org/scientific_prospectus/402/402SP.PDF">scientific prospectus</a> in the weeks leading up to expedition 402. Rationally it felt straightforward to understand that under different circumstances like temperature and pressure sediment and rocks react in certain ways. It felt straightforward to understand that these materials will undergo change, erosion, weathering, layering and more. But once I saw the actual cores a foot away from my face, it was a whole other beast. That is the value of field work and that is the value of this ship. You cannot learn more about this planet if you do not have access to it.</p>

<p>As I reflected on my two expedition experiences and saw the science crew experience a range of emotions as new cores were collected, I decided to go around and ask some people who have been on multiple expeditions for their perspectives.</p>
<p><strong>“What has surprised you about the rocks and sediment you have seen across expeditions?”</strong></p>
<p>Alejandro has sailed on 8 expeditions (or 6, he wasn’t entirely sure) and is sailing as the Physical Properties Lab Specialist. He is most surprised by the homogeneity (the sameness) and the gradual change in characteristics of the cores from the bigger oceans. When he was in the Pacific it took a few cores before you started to see a huge color change or texture change, while in the shallower basins the cores tend to be more heterogenous (varied) and have more rapid changes to their features. It always keeps him asking why.</p>
<figure id="attachment_40824" aria-describedby="caption-attachment-40824" style="width: 225px" class="wp-caption alignnone"><img loading="lazy" decoding="async" class="size-medium wp-image-40824" src="https://joidesresolution.org/wp-content/uploads/2024/02/IMG_20201216_063534-225x300.jpg" alt="" width="225" height="300" srcset="https://joidesresolution.org/wp-content/uploads/2024/02/IMG_20201216_063534-225x300.jpg 225w, https://joidesresolution.org/wp-content/uploads/2024/02/IMG_20201216_063534-768x1024.jpg 768w, https://joidesresolution.org/wp-content/uploads/2024/02/IMG_20201216_063534-1152x1536.jpg 1152w, https://joidesresolution.org/wp-content/uploads/2024/02/IMG_20201216_063534-1536x2048.jpg 1536w, https://joidesresolution.org/wp-content/uploads/2024/02/IMG_20201216_063534-scaled.jpg 1920w" sizes="auto, (max-width: 225px) 100vw, 225px" /><figcaption id="caption-attachment-40824" class="wp-caption-text">Alejandro, physical properties marine technician.</figcaption></figure>
<p>Emily Estes has sailed on 4 expeditions with the <em>JOIDES Resolution</em> and is the current Expedition Project Manager. She is surprised that even when we have the prospectus identifying everything that we expect and understand to be in the area, we still find something different. Especially when the data in the prospectus is based on previous drilling sites in the area, one would think the core would bring few surprises. Though she does not think of these moments as bad surprises, but as opportunities to ask more questions. Most of her work and expeditions have been in larger oceanic basins where there are similar features throughout multiple cores before it starts to change, which is not the case for the shallower basins like the Tyrrhenian Sea.</p>
<figure id="attachment_40825" aria-describedby="caption-attachment-40825" style="width: 300px" class="wp-caption alignnone"><img loading="lazy" decoding="async" class="wp-image-40825 size-medium" src="https://joidesresolution.org/wp-content/uploads/2024/02/exp390C_101-1-300x200.jpg" alt="" width="300" height="200" srcset="https://joidesresolution.org/wp-content/uploads/2024/02/exp390C_101-1-300x200.jpg 300w, https://joidesresolution.org/wp-content/uploads/2024/02/exp390C_101-1-1024x683.jpg 1024w, https://joidesresolution.org/wp-content/uploads/2024/02/exp390C_101-1-768x512.jpg 768w, https://joidesresolution.org/wp-content/uploads/2024/02/exp390C_101-1-1536x1024.jpg 1536w, https://joidesresolution.org/wp-content/uploads/2024/02/exp390C_101-1-2048x1365.jpg 2048w" sizes="auto, (max-width: 300px) 100vw, 300px" /><figcaption id="caption-attachment-40825" class="wp-caption-text">Emily Estes excited about some data on Rig Watch, a system used to monitor the drilling performance.</figcaption></figure>
<p>Kevin Grigar has sailed on 24 expeditions and is the Operations Superintendent. Though his role is to check how well the cores are coming out to help determine with SIEM Offshore what could change about the drilling operations and procedures, he still gives the cores a look. What surprises him is the change in formations and color throughout the cores, sometimes within the same core and sometimes it is after a few ones. Either way he is amazed, and loves how pretty the changes can look.</p>
<figure id="attachment_40828" aria-describedby="caption-attachment-40828" style="width: 225px" class="wp-caption alignnone"><img loading="lazy" decoding="async" class="size-medium wp-image-40828" src="https://joidesresolution.org/wp-content/uploads/2024/02/IMG_9731-225x300.jpg" alt="" width="225" height="300" srcset="https://joidesresolution.org/wp-content/uploads/2024/02/IMG_9731-225x300.jpg 225w, https://joidesresolution.org/wp-content/uploads/2024/02/IMG_9731-768x1024.jpg 768w, https://joidesresolution.org/wp-content/uploads/2024/02/IMG_9731-1152x1536.jpg 1152w, https://joidesresolution.org/wp-content/uploads/2024/02/IMG_9731-1536x2048.jpg 1536w, https://joidesresolution.org/wp-content/uploads/2024/02/IMG_9731-scaled.jpg 1920w" sizes="auto, (max-width: 225px) 100vw, 225px" /><figcaption id="caption-attachment-40828" class="wp-caption-text">Kevin Grigar in his office on the bridge deck.</figcaption></figure>
<p>James Kowalski has sailed on 3 expeditions and is sailing as the ship curator. He is surprised by the laminations (layering that happens in sedimentary rocks) and features that disappear quickly between cores. He finds that each core is so different and rarely sees similarity across expeditions. The variety is something that he enjoys and it keeps him on his toes.</p>
<figure id="attachment_40829" aria-describedby="caption-attachment-40829" style="width: 172px" class="wp-caption alignnone"><img loading="lazy" decoding="async" class="wp-image-40829 size-medium" src="https://joidesresolution.org/wp-content/uploads/2024/02/IMG_3624-172x300.jpg" alt="" width="172" height="300" srcset="https://joidesresolution.org/wp-content/uploads/2024/02/IMG_3624-172x300.jpg 172w, https://joidesresolution.org/wp-content/uploads/2024/02/IMG_3624-588x1024.jpg 588w, https://joidesresolution.org/wp-content/uploads/2024/02/IMG_3624-768x1337.jpg 768w, https://joidesresolution.org/wp-content/uploads/2024/02/IMG_3624-882x1536.jpg 882w, https://joidesresolution.org/wp-content/uploads/2024/02/IMG_3624-1176x2048.jpg 1176w, https://joidesresolution.org/wp-content/uploads/2024/02/IMG_3624.jpg 1283w" sizes="auto, (max-width: 172px) 100vw, 172px" /><figcaption id="caption-attachment-40829" class="wp-caption-text">James on the core catwalk preparing the measurements for the core to be sectioned off into 150cm pieces.</figcaption></figure>
<p>Hearing their responses made me think of the cycle of scientific thinking (https://www.youtube.com/watch?v=j12BBcKSgEQ)  and what one of our co-chiefs, Nevio Zitellini, said the other day “We start this expedition with a question, and we end this expedition with more questions.”</p>
<p>&nbsp;</p>
<p>As we settle into week 3 of Expedition 402, I enter it even more consumed by two notions. First, that we still have so much to learn, and secondly, it seems that when I ask “how could rocks and sediment from one ocean to another be different” it is a question that scientists and the public, alike, share.</p>

										<content:encoded><![CDATA[<p>Ahoy there, landlubbers and salty sea dogs alike! Let me spin you a yarn about a peculiar treasure found aboard the vessels that brave the briny deep – the wondrous world of sailor&#8217;s pet pics!</p>
<p>Picture this: you&#8217;re on a ship, surrounded by nothing but the endless expanse of the ocean. It&#8217;s just you, your shipmates, and a bunch of sediment ready to be analyzed. But wait! What&#8217;s that on the wall? It&#8217;s not a map of buried treasure or a portrait of a fearsome pirate. No, it&#8217;s something far more precious – it&#8217;s a photograph of a sailor&#8217;s furry first mate!</p>
<p>You see, sailors and scientists alike have a soft spot for their four-legged friends back on land. And what better way to keep their spirits high during long voyages than by surrounding themselves with reminders of home? So, they plaster their cabins with pictures of their pets – from loyal Labradors to frisky felines– each one a precious piece of their heart left behind on shore. Instead of keeping these treasures locked up in individual rooms, we decided to dedicate a public wall for all to enjoy the uplifting benefits of “Critter Comfort Care”.</p>
<p>But these pet pics aren&#8217;t just for show – oh no! They&#8217;re an essential part of life at sea. Need a morale boost after a rough day battling the waves? Just take a gander at some cat&#8217;s cheeky grin, or the head tilt of a dog and all your troubles will melt away faster than ice cream on a hot deck.</p>
<p>Perhaps the best part of all is the camaraderie that pet pics inspire among sailors. Swap stories about your furry friends, share tips on pet training (hint: treats or belly rubs are always the answer), and bond over the universal truth that pets are the best thing since sliced bread – or, in the case of sailors, since rum.  We’ve already shared many laughs over our wild pet stories!</p>
<p>In addition to wild pet stories, Tessa went around to some of the scientists and asked them what science they their pet would be interested in. Here is what she learned.</p>
<p>Dakota (The Queen) would follow a path in toxicology because she is mischievous and pays attention to the little things. Toxicology is the science that aims to understand the effects, and interactions harmful substances can have on the environment and living things.</p>

<p>Bruno: After getting tired of his kibble, he has gotten a taste for pairing foods with each other.Thus Bruno would go into the food sciences to determine the best food combinations for his newly refined palate. The food sciences are a mixture of different fields but it is the applied science of making different food products. For instance, it is involved with determining shelf life or safety of different food products.</p>

<p>Banjo: Though sometimes it seems he has no thoughts in his brain, it is understood that because of his love for snow he would study Glaciology.Glaciology is an earth science that is paired with other fields to understand the impact and development of ice/glaciers in our world.</p>

<p>Moxie: Judgmental of all things not true, it is believed that Moxie would be a mathematician. They would appreciate the absolute truths that come with numbers and theory of the universe, but nothing else.  Mathematicians aim to solve real world problems and compare old principles to newer principles. They tend to concerned with numbers, data, structures, space and more.</p>
<figure id="attachment_40801" aria-describedby="caption-attachment-40801" style="width: 225px" class="wp-caption alignnone"><img loading="lazy" decoding="async" class="size-medium wp-image-40801" src="https://joidesresolution.org/wp-content/uploads/2024/02/PHOTO-2024-02-21-14-38-12-225x300.jpg" alt="" width="225" height="300" srcset="https://joidesresolution.org/wp-content/uploads/2024/02/PHOTO-2024-02-21-14-38-12-225x300.jpg 225w, https://joidesresolution.org/wp-content/uploads/2024/02/PHOTO-2024-02-21-14-38-12.jpg 768w" sizes="auto, (max-width: 225px) 100vw, 225px" /><figcaption id="caption-attachment-40801" class="wp-caption-text">Moxie enjoying a field of flowers</figcaption></figure>
<p>All in all, the next time you find yourself aboard a ship, keep an eye out for those precious pet pics adorning the walls. They may just be scraps of paper to some, but to sailors, they&#8217;re a lifeline to the fur babies they left behind on dry land. So, let&#8217;s raise a toast to the furry, feathery, and scaly companions who keep our spirits afloat even in the roughest seas. Here’s to pet therapy- or should we say, “Tail Wagging Treatment”- because sometimes, all you need is a paw-sitive reminder of home to make even the stormiest voyage feel like smooth sailing!</p>
