Hi crew: So what is “ooze” anyway? Well, there are two flavors:siliceous ooze and calcareous ooze. There are many, many types of microscopic organisms that live in the sunlit surface waters of the world ocean (don’t drink the water!). But some produce mineralized hard parts that preserve to the sediments; that is why geologists study these beasts.

From time to time we'll combine or alternate between Ron's reports and the science updates I send to shore. There's so much science and so little time... Remember that we post all official reports on the IODP United States Implementing Organization website where you can always access more detail. Got questions?&

It has been at least a week since we've posted a science update. If you're following Expedition 320, however, you know that among other things, we're looking for and finding microfossils-- tiny radiolarians, foraminiferans, and calcareous nannofossils that help our scientists tease out the stories of climatic events of the past 50 million years.

Despite their excellent name, Discoasters do not resemble John Travolta. Instead they look like the second half of their name ("-aster"). They are microscopic algae whose fossilized remains resemble an asterix (*).
