<content:encoded><![CDATA[<p>An Bord der JOIDES Resolution ist die “Core-Description” eine der zentralen Aufgaben der Wissenschaftler bei der Auswertung der Bohrkerne. Aus Deutschland ist Elmar Albers, Doktorand an der Uni Bremen, mit dabei. Die “Core-Description-Group” hat die Aufgabe, die Bohrkerne genau zu beschreiben und detaillierte Berichte darüber zu verfassen. Dafür stehen die Wissenschaftler manchmal stundenlang an den “Description-Tables” (siehe Foto unten). Elmar ist die Arbeit auf einem Forschungsschiff gewohnt, denn er ist praktisch nur umgestiegen. Kurz vor unserer Expedition war er mit dem deutschen Forschungsschiff Polarstern für sechs Wochen in der Arktis.</p>
<p><img fetchpriority="high" decoding="async" class="alignnone size-full wp-image-23170" src="https://joidesresolution.org//wp-content/uploads/2017/02/Elmar3.jpg" alt="" width="640" height="361" srcset="https://joidesresolution.org/wp-content/uploads/2017/02/Elmar3.jpg 640w, https://joidesresolution.org/wp-content/uploads/2017/02/Elmar3-300x169.jpg 300w" sizes="(max-width: 640px) 100vw, 640px" /></p>
<p>Was bewegt denn einen jungen Wissenschaftler dazu, gleich mehrere Expeditionen hintereinander zu belegen? Für Elmar klare Sache: Herausfinden, was an verschiedenen Orten mit Mantelgesteinen und anderen Tiefengesteinen passiert, wenn sie unter wechselnden Druck- und Temperaturbedingungen mit Fluiden reagieren. <a class="glossary-term" href="http://archive.joidesresolution.org/glossary/9#term408"><dfn title="Look up the definition of Gabbro.">Gabbro</dfn></a>ide Schmelzen reagieren zum Beispiel anders als Mantelgesteine wie Peridotit. Auch unterscheiden sich die Vorgänge an mittelozeanischen Rücken deutlich von denen an Subduktionszonen, wie wir sie hier am Marianengraben vorfinden.</p>
<p><img decoding="async" class="alignnone size-full wp-image-23169" src="https://joidesresolution.org//wp-content/uploads/2017/02/Elmar2.jpg" alt="" width="640" height="640" srcset="https://joidesresolution.org/wp-content/uploads/2017/02/Elmar2.jpg 640w, https://joidesresolution.org/wp-content/uploads/2017/02/Elmar2-150x150.jpg 150w, https://joidesresolution.org/wp-content/uploads/2017/02/Elmar2-300x300.jpg 300w" sizes="(max-width: 640px) 100vw, 640px" /></p>
<p> </p>
<p>Elmar ist im Rahmen seiner Dissertation den geochemischen Veränderungen auf der Spur, die zwischen Fluiden und Erdmantelgestein stattfinden. Die Proben, die er auf dieser Expedition gesammelt hat, werden ihn daher die nächsten Jahre beschäftigen, bis sie vollständig ausgewertet sind. Dann wird Elmar noch mehr darüber wissen, warum harte Gesteine schließlich zu Serpentin und damit weich werden. Weich genug, um die Schlammvulkane zu bilden, die wir im Rahmen dieser Expedition westlich des Marianengrabens beprobt haben.</p>

<content:encoded><![CDATA[<p>Sorry to have been offline so long – but we have been BUSY here!</p>
<p>When I last blogged we were doing an elaborate set of re-visits of all of the summits of our three seamounts – Yinazao, Asut Tesoru, and Fantangisna – to check on the fidelity of the cased holes we had drilled. One of them – Asut Tesoru – actually needed to be cleaned out because serpentine muds were actively rising up the pipe (!!), so we cored and collected that mud and its associated waters (creating a sudden rush in our lab), while the drillers dropped concrete down into the hole to keep it from happening anymore. We then moved on back to Fantangisna, and after assuring ourselves that our summit hole was stable, we thrustered slowly (at ~1 knot) away to begin drilling at our last approved site on the Fantangisna seamount’s flank.</p>
<p align="center"><img decoding="async" class="alignnone size-medium wp-image-23173" src="https://joidesresolution.org//wp-content/uploads/2017/01/Fantangisna-fun-225x300.jpg" alt="" width="225" height="300" srcset="https://joidesresolution.org/wp-content/uploads/2017/01/Fantangisna-fun-225x300.jpg 225w, https://joidesresolution.org/wp-content/uploads/2017/01/Fantangisna-fun.jpg 640w" sizes="(max-width: 225px) 100vw, 225px" /> <img loading="lazy" decoding="async" class="wp-image-23177 size-medium alignnone" src="https://joidesresolution.org//wp-content/uploads/2017/01/Redcore-230x300.jpg" alt="" width="230" height="300" srcset="https://joidesresolution.org/wp-content/uploads/2017/01/Redcore-230x300.jpg 230w, https://joidesresolution.org/wp-content/uploads/2017/01/Redcore.jpg 640w" sizes="auto, (max-width: 230px) 100vw, 230px" /></p>

<p>This flank hole was different from the start: first we hit rocks (!!!) – fresh chunks of ultramafic rock, like we hadn’t seen all Expedition (it got the Core Description team very excited!). And then it was colored sand – and then quickly blue, drilling-disturbed mud like we’d been seeing – and then the mud turned red (???). And then we were in brown volcanic clays and ashes, all in less than 40 m of drilling. Now this last bit was a good thing – one of the targets for the flank hole here was to drill through serpentinite and hit the “basement” sediments and volcanic rocks, and it looked like we did that, but it had happened too shallow to meet the other Site objective, which was to conduct a geophysical log of the hole to provide more insights into the seamount’s interior structure. Our conclusion was that we were TOO far downslope, so they revved up the thrusters and slowly moved us about 600+ meters uphill to try again.</p>
<p>Our magnificent last drillhole at Fantangisna – Hole U1498B:</p>

<p>Rocks. HUGE, thick rocks. More and swirlier muds. More core – recovery was incredible, up to 8 m of a 9.5 m core section, which given that we were doing Rotary Core Barrel (RCB) drilling was astonishing. More work – squeezing these hard muds (5-6 hours to get any porefluids out of them!), while trying to analyze the rocks from the other sites that we’d already collected and prepared. And it went on for 250+ meters of drilling, until we hit those ashes again which told us we were finally through the flank of Fantangisna and into the crust it sits on. The hole amazingly maintained its stability and we were able to log it from top to bottom, so we have a geophysical record of the interior of Fantangisna to compare to our rock record. A more successful hole there could not be. An excellent way to finish our explorations!</p>

<p>We are now on a long (7 day) transit from Fantangisna, past the Mariana islands and Taiwan and across the North China Sea to Hong Kong, where our cruise will officially end. Before that, however, is finalizing our reports on our findings, and (in the Geochemistry Lab) our usual game of catch-up, as we analyze all the samples we collected from Holes U1498A and B. Some of this we had to get done before transit (our ICP-AES instrument doesn’t like ship motion….) but the rest will continue for several days, after which we’ll scramble to get our final Site Chapters completed and revised. And we’re finalizing the samples we’ll take home to our labs to continue our work, to fully flesh out the geology (and biology) of this unique place on our planet.</p>
<p>[I promise to make 1-2 more entries in the next couple days, to make up for being preoccupied – so stay tuned!]</p>

<p style="margin-top: 0.3em; margin-bottom: 9pt;"><span style="color: #000072; font-family: Georgia; font-size: 19px;">One of the two Co-Chief-scientists of Expedition 366 is Patty Fryer, a Professor of Geology at the University of Hawaii. She is mainly concerned with plate-tectonics, the metamorphism of supra-subduction zone regions and the associated production of serpentine mud and other geochemical cycles.</span></p>
<p style="margin-top: 0.3em; margin-bottom: 9pt; text-align: justify;"><img loading="lazy" decoding="async" class="alignnone size-full wp-image-23191" src="https://joidesresolution.org//wp-content/uploads/2017/01/PF2.jpg" alt="" width="640" height="480" srcset="https://joidesresolution.org/wp-content/uploads/2017/01/PF2.jpg 640w, https://joidesresolution.org/wp-content/uploads/2017/01/PF2-300x225.jpg 300w" sizes="auto, (max-width: 640px) 100vw, 640px" /></p>
<p style="margin-top: 0.3em; margin-bottom: 9pt; text-align: justify;"><span lang="EN-US" style="font-size: 14pt; font-family: Georgia; color: #000072;">Photo:Co-Chief- Scientists: Patty Fryer and Geoffrey Wheat</span></p>
<p style="margin-top: 0.3em; margin-bottom: 9pt; text-align: justify;"><span lang="EN-US" style="font-size: 14pt; font-family: Georgia; color: #000072;">When one summarizes the times Patty Fryer has spent on research vessels exploring the earth under the sea, it turns out that it has been more than three years. Among these expeditions have been really striking ones, like the first use of the ROV (remotely operated vehicle) Nereus for a test in Hawaii in 2008 and the exploration of the Challenger Deep in 2009 with it. In 2012 Patty came back to the Challenger Deep together with James Cameron, to advise further exploration of Earth’s deepest point under the sea. Why then is she going one more time at sea with IODP Expedition 366 on board of the JOIDES Resolution? </span></p>
<p style="margin-top: 0.3em; margin-bottom: 9pt; text-align: justify;"><span lang="EN-US" style="font-size: 14pt; font-family: Georgia; color: #000072;">There is a clear answer to this: “To take the pulse of subduction”. She explains to me, that earthquakes at suduction zones like the Mariana Convergent Margin likely correlate with fluid releases out of the down -going plate, which cause eruptions of the serpentinite mud volcanoes, like the ones we are exploring on this expedition. Patty outlines the option of a future monitoring of earthquake and mud-volcano-eruptions based on the drill-holes at three mud-volcanoes that we equipped with screened casings during our expedition. </span></p>
<p style="margin-top: 0.3em; margin-bottom: 9pt; text-align: justify;"><span lang="EN-US" style="font-size: 14pt; font-family: Georgia; color: #000072;">One may ask, if there are any secrets to be expected in the blue-green serpentinite mud. Patty is sure, that there are some. For example the color itself is unexplained. Furthermore, she expects more information about how life may have come into existence on the early Earth. Focus on that research has shifted from hydrothermal systems at mid-ocean ridges to subduction zones, mainly because of the cooler temperatures, the highly reducing conditions and the availability of hydrogen and methane. </span></p>
<p style="margin-top: 0.3em; margin-bottom: 9pt; text-align: justify;"><img loading="lazy" decoding="async" class="alignnone size-full wp-image-23192" src="https://joidesresolution.org//wp-content/uploads/2017/01/ProfPF3.jpg" alt="" width="640" height="640" srcset="https://joidesresolution.org/wp-content/uploads/2017/01/ProfPF3.jpg 640w, https://joidesresolution.org/wp-content/uploads/2017/01/ProfPF3-150x150.jpg 150w, https://joidesresolution.org/wp-content/uploads/2017/01/ProfPF3-300x300.jpg 300w" sizes="auto, (max-width: 640px) 100vw, 640px" /></p>
<p style="margin-top: 0.3em; margin-bottom: 9pt; text-align: justify;"><span lang="EN-US" style="font-size: 14pt; font-family: Georgia; color: #000072;">Photo: Blue Serpentinite Mud</span></p>
<p style="margin-top: 0.3em; margin-bottom: 9pt; text-align: justify;"><span lang="EN-US" style="font-size: 14pt; font-family: Georgia; color: #000072;">Has she imagined before drilling into the seafloor, what might be going on down there, is my next question. Sure she has. She can almost see the fluids being released during an earthquake on the top of the down-going Pacific plate, rising along the ground-up faces of faults, invading the surrounding rocks like grasping fingers, turning everything it touches to serpentine, and rising as a mush through the mud volcano conduits to burp, or flow out onto the seafloor and form monstrous mounds of mud. One believes, that for a visionary Geologist like her the thrill of discovery will never end. </span></p>
<p style="margin-top: 0.3em; margin-bottom: 9pt;"><span lang="EN-US" style="font-size: 14pt; font-family: Georgia; color: #000072;">Finally I want to know, if in her opinion the knowledge of geosciences increases respect for nature in the scientist himself. “Absolutely yes”, Patty says, “in so many ways. It makes us feel so small when we realize the grandure of nature and see, how interrelated all the fields of science are. How can you not love nature, when you learn more and more about it”?</span></p>
<p style="margin-top: 0.3em; margin-bottom: 9pt;"><span lang="EN-US" style="font-size: 14pt; font-family: Georgia; color: #000072;">So it seems to me, that Dr. Patty Fryer is not only taking the pulses of subduction, but also sensitive to different other pulses of the Earth.</span></p>

<content:encoded><![CDATA[<p>Fantangisña (Celestial-) <a class="glossary-term" href="http://archive.joidesresolution.org/glossary/9#term646"><dfn title="Look up the definition of Seamount.">Seamount</dfn></a>,<br />
visited a second time, is supposed to be our last site on this extraordinary<br />
expedition to the Serpentinite Mud Volcanoes. But last time we left something.<br />
A positioning beacon, having been lowered to the seafloor, did not come up<br />
again. Since it was clear, that we would come back, we simply left it on the<br />
sefloor. This time the crew managed to pick it up with a hook and bring it back<br />
on board, before we moved to the last drill-site at this seamount. It sounds<br />
pretty easy, doesn’t it? Take a look at the hook!</p>
<p>Fantangisña (dt. der Himmlische)<br />
Schlammvulkan ist mit diesem 2. Besuch vermutlich die letzte Station vor dem<br />
Transit nach Hongkong. Aber beim ersten Mal haben wir etwas zurückgelassen.<br />
Eine Positionierungs-Sonde, die auf den Meeresgrund hinabgesenkt wurde, ist<br />
nicht wieder aufgetaucht. Da zu diesem Zeitpunkt bereits feststand, dass wir<br />
zurückkehren würden, hat man sie einfach dort stehen gelassen. Nun, beim<br />
zweiten Besuch, haben wir die exakte Stelle wieder angefahren und die Sonde mit<br />
einem Haken vom Meeresgrund gefischt. Hört sich ganz einfach an, oder? Seht<br />
euch den Haken an!</p>
<p><img loading="lazy" decoding="async" class="alignnone size-full wp-image-23196" src="https://joidesresolution.org//wp-content/uploads/2017/01/Fantan2-1.jpg" alt="" width="640" height="854" srcset="https://joidesresolution.org/wp-content/uploads/2017/01/Fantan2-1.jpg 640w, https://joidesresolution.org/wp-content/uploads/2017/01/Fantan2-1-225x300.jpg 225w" sizes="auto, (max-width: 640px) 100vw, 640px" /></p>
<p>I think Fantangisña-Seamount is<br />
somehow really an celestial end for our investigation, as it’s name indicates.<br />
The cores from this seamount are surely the most differentiated ones concerning<br />
texture and color. It is not yet clear, if they turn out to be the<br />
scientifically most important ones, but they seem to be the nicest and most<br />
interesting ones at the first impressions. Maybe the secret of the different<br />
colors of Serpentine-Mud will be disclosed from the analysis of these samples.</p>
<p>Der Fantangisña-Schlammvulkan ist<br />
in gewisser Hinsicht wirklich ein “himmlisches Ende” unserer<br />
Untersuchungen. Die Bohrkerne aus diesem Schlammvulkan haben bei weitem die<br />
größte Vielfalt an Textur und Farben. Es ist noch nicht klar, ob sie auch<br />
geologisch diejenigen mit der größten Bedeutung sein werden, aber es sind die<br />
Schönsten und auf den ersten Blick die Interessantesten. Vielleicht wird ja das<br />
Geheimnis der Farbe des Serpentinit-Schlamms anhand der Auswertung dieser<br />
Proben gelöst werden.</p>

<p>So scientists have future work, educators stay curious and co-chief scientists look quite content, when we managed to drill all through the flank of the mud-volcano into the underlying reddish-brown seafloor-sediments (see Photo below and Attachments).</p>
<p>Die Wissenschaftler haben also genug Arbeit für die Zukunft und die Co-Chiefs sehen ganz zufrieden aus, nachdem wir heut durch die Flanke des Schlammvulkans in die unterlagernden rot-braunen Meeres-Sedimente gebohrt haben. (siehe Foto unten und Anhänge).</p>

<content:encoded><![CDATA[<p>We are currently sailing north toward Asut Tesoru Seamount, after having spent a day pounding a stuck bridge plug down the 200+ meter cased hole at Yinazao Seamount. This after several days reaming and casing a hole at Fantangisna Seamount – which we’re going to visit again, to check on how cement in that hole is holding up, after we sort out what’s happening at the bottom of the cased hole at Asut Tesoru. So, yes – we’re entirely retracing our steps from the last five weeks here, in about 5 days (if all goes well), all to be sure that the three holes we’ve drilled and cased will be there and usable when, at some undefined point in the future, another (non IODP) Expedition is funded and sails out to place instruments in these holes to monitor the uwelling fluids we’ve documented in each of them (or in at least two of them – the jury may still be out on Fantangisna!).</p>
<p>IF all goes well, then we head downslope on Fantangisna Seamount, to address the one un-visited approved site in our Prospectus – and we stay there and drill and drill until we run out of time at the end of this month, and have to head to Hong Kong! So, as you might imagine, there is a LOT of rooting for our drillers and engineers to make this all go smoothly! And so far, so good….</p>
<p align="center"><img loading="lazy" decoding="async" class="alignnone wp-image-23201 size-medium" src="https://joidesresolution.org//wp-content/uploads/2017/01/Drillstring-1950-300x225.jpg" alt="" width="300" height="225" srcset="https://joidesresolution.org/wp-content/uploads/2017/01/Drillstring-1950-300x225.jpg 300w, https://joidesresolution.org/wp-content/uploads/2017/01/Drillstring-1950.jpg 640w" sizes="auto, (max-width: 300px) 100vw, 300px" /> <img loading="lazy" decoding="async" class="alignnone size-medium wp-image-23203" src="https://joidesresolution.org//wp-content/uploads/2017/01/Moonpoolconst-300x225.jpg" alt="" width="300" height="225" srcset="https://joidesresolution.org/wp-content/uploads/2017/01/Moonpoolconst-300x225.jpg 300w, https://joidesresolution.org/wp-content/uploads/2017/01/Moonpoolconst.jpg 640w" sizes="auto, (max-width: 300px) 100vw, 300px" /></p>
<p align="center"><img loading="lazy" decoding="async" class="alignnone size-medium wp-image-23202" src="https://joidesresolution.org//wp-content/uploads/2017/01/Drillstring-2006-oops-300x225.jpg" alt="" width="300" height="225" srcset="https://joidesresolution.org/wp-content/uploads/2017/01/Drillstring-2006-oops-300x225.jpg 300w, https://joidesresolution.org/wp-content/uploads/2017/01/Drillstring-2006-oops.jpg 640w" sizes="auto, (max-width: 300px) 100vw, 300px" /> <img loading="lazy" decoding="async" class="alignnone size-medium wp-image-23204" src="https://joidesresolution.org//wp-content/uploads/2017/01/Moonpooldrop-300x225.jpg" alt="" width="300" height="225" srcset="https://joidesresolution.org/wp-content/uploads/2017/01/Moonpooldrop-300x225.jpg 300w, https://joidesresolution.org/wp-content/uploads/2017/01/Moonpooldrop.jpg 640w" sizes="auto, (max-width: 300px) 100vw, 300px" /></p>
<p>Now this is not to say that EVERYTHING runs smoothly all the time. We are, after all, working from an unmoored ship on a rolling ocean, and this is going to produce some unanticipated outcomes – like the casing mount letting loose 5o+ meters too early and sliding down into the hole before they were ready for it, as an example! However, our drilling engineers have been consistently adroit at taking what the seas give them and making it work out, so, perhaps for everyone but our Co-Chiefs (who, I think, have had more than their share of heart palpitations looking at our video monitors!), it’s seemed like this has all been sort of routine, even though even a moment’s reflection on what is actually happening leaves you certain that it’s anything but.</p>
<p align="center"><img loading="lazy" decoding="async" class="alignnone size-medium wp-image-23205" src="https://joidesresolution.org//wp-content/uploads/2017/01/Popularrocks-225x300.jpg" alt="" width="225" height="300" srcset="https://joidesresolution.org/wp-content/uploads/2017/01/Popularrocks-225x300.jpg 225w, https://joidesresolution.org/wp-content/uploads/2017/01/Popularrocks.jpg 640w" sizes="auto, (max-width: 225px) 100vw, 225px" /> <img loading="lazy" decoding="async" class="alignnone size-medium wp-image-23206" src="https://joidesresolution.org//wp-content/uploads/2017/01/science-prez-300x225.jpg" alt="" width="300" height="225" srcset="https://joidesresolution.org/wp-content/uploads/2017/01/science-prez-300x225.jpg 300w, https://joidesresolution.org/wp-content/uploads/2017/01/science-prez.jpg 640w" sizes="auto, (max-width: 300px) 100vw, 300px" /></p>
<p>While we’re waiting for all this engineering to be done, we’re getting caught up on both the drudgery and the fun of the science. Drudgery comes in the form of report writing – all the Sites we visit become Chapters in our Expedition Volume, and the initial versions of these must be completed before we leave the ship. As we’ve visited three different seamounts at their summits and (so far) two of their flanks, we have five reports to complete for each laboratory on the ship. In my lab, Geochemistry, we’re always playing catch-up because before we can report we have to analyze our samples and that takes extra time – so the extra down-time is a benefit. The fun is in sorting out the science we’ll do through our samples – we had a special “sample party” for a unique section of Site U1496 core where we selected the key samples, established a plan for coordinated analysis, and a timeline for getting it all done on a short fuse once we’re home. The other “fun” is in discussing the science – reporting to each other on our findings from the recent sites (U1496 just got discussed, and U1497 is coming), and in playing with our data some, as several of our number did at a recent crossover meeting to try and develop a reasonable evolution and timeline model for the growth of Asut Tesoru, using our physical property results in interesting and creative ways.</p>
<p>We’re also talking more about Hong Kong, and about home: football playoffs and other entertainments on the satellite feed TV are reminding us all how long we’ve been out here (well, that and the disappearance of lettuce from the salad bar!). With two weeks or a bit more left in our Expedition, we’re close enough to start thinking about our normal lives, but still far enough away that it’s not quite real, not yet. I for one am looking forward to at least one more adventure, and a few more shouts of “Core on Deck!” with weird things in the liners to finish this Expedition off properly.</p>

<content:encoded><![CDATA[<div>Today during one of my live classroom broadcasts, a student asked what it felt like to be higher than Mount Everest. The student was referring to our location above the Mariana Trench–the deepest part of the ocean (35,827 feet deep), often contrasted with Mount Everest since its the highest point on earth (29,035 feet high).</div>
<div></div>
<div>So in other words, what does it feel like to be floating above the deepest place we know of on the planet?</div>
<div></div>
<div><em>(Left: the observation camera catches a glimpse of a curious squid about 200 meters below the surface)</em></div>
<div></div>
<div></div>
<div>Technically, our ship is not directly over the Mariana Trench right now; rather we are traveling over the Mariana Forearc, the shallower ridge due west of the trench where the unique serpentinite mud volcanoes form that our scientists are so interested in. Still, our target volcanoes are a good 6,000 to 18,000 feet below the sea surface, depending on the site.</div>

<div>
<div><em>A side view schematic of one of our coring sites, Big Blue <a class="glossary-term" href="http://archive.joidesresolution.org/glossary/9#term646"><dfn title="Look up the definition of Seamount.">Seamount</dfn></a>, whose base reaches 5400 feet below the sea surface.</em></div>
<div><em> </em></div>
<div>In other words, there’s a lot of ocean between our ship and the seafloor. It’s hard to truly understand just how much water that is, but being aboard the JOIDES Resolution has at least given me a bit more perspective. For one, it takes several hours for the ship’s drill and pipe to reach the seafloor and return back to the ship. You could fly across the entire United States in the same amount of time it takes us to reach the seafloor and return in some cases.</div>
<div></div>
<div>Sometimes, the drill technicians lower a camera down with the pipe when they need to locate the re-entry cone (the device that keeps our drilled hole open and visible on the seafloor), so it’s possible to watch the camera travel on its several hour journey down to the seafloor. I can’t say I’ve sat through the whole adventure down and back, but I’ve spend a few good chunks of time observing the camera to see what the ocean looks like several hundred to thousands of meters deep.</div>
<div></div>
<div>Near the sea surface (anywhere down to about 100-200 meters) you are likely to spot several kinds of fish—tuna, mahimahi, trigger fish, and others—plus squid and other interesting creatures zooming past the camera. On the seafloor, you can often pick out invertebrates like mussels or crabs, as well as sponges and mats of archaea or bacteria. But in between, in what’s called the Bathypelagic Zone (or my preferred name, the Midnight Zone), there’s a lot of nothing. Okay, not really nothing, but most things below the photic zone (the area of the ocean that light can penetrate) are tiny and/or hard to see. Little shrimps, zooplankton, bacteria, and tons of ‘marine snow’. And a lot of watery darkness.</div>
</div>
<div><img loading="lazy" decoding="async" class="alignnone size-full wp-image-23209" src="https://joidesresolution.org//wp-content/uploads/2017/01/Ocean-zones.jpg" alt="" width="440" height="656" srcset="https://joidesresolution.org/wp-content/uploads/2017/01/Ocean-zones.jpg 440w, https://joidesresolution.org/wp-content/uploads/2017/01/Ocean-zones-201x300.jpg 201w" sizes="auto, (max-width: 440px) 100vw, 440px" /></div>
<div></div>

<div><em>The bathypelagic zone (Midnight Zone) lies more than 1,000 feet below where sunlight can penetrate. Our camera passes through this zone to reach our target seamounts on the Mariana Forearc. (Image: Te Ara Encyclopedia of New Zealand)</em></div>
<div><em> </em></div>
<div>Just as observing stars on a clear night can be humbling to the ego, watching the camera plunge deeper and deeper into oceanic darkness (save for the bit of light projected from the camera itself) for hours on end has altered my perspective on the scale and nature of earth’s processes. After five weeks on the ship, when everyone is fairly set in their daily routines and the novelty of living at sea has faded, I think it’s these random observations that become more meaningful. Watching endless rolling waves meet a surreal sunrise; touching rocks that have traveled from deep within our planet up through a mud volcano and into our core sample by sheer chance; and yes, even watching a camera go down and down through a seemingly empty ocean for hours, all leave their imprints on the mind.</div>
<div></div>
<div>In the few weeks that remain of Expedition 366, the science party will be working hard to finish their analyses of our core samples and write their assigned reports before we reach Hong Kong. There’s no question that this expedition has uncovered exciting new information about how subduction zones function, how serpentine muds are formed, and how life may have started in these types of environments. But what you won’t read about in the reports or scientific papers from this expedition are the moments of clarity, humility, shared laughter, and solitude that subtly changed each of us along the way. For that, you’ll have to ask for the unwritten story—or take a similar journey yourself!</div>
