Small sample of permafrost
Earlier, Catherine asked about coring rock, sediment, or ice sheets. As a reader of PolarTREC journals, Catherine is hoping to learn more about the geological history of the area. There isn't any…

Note: Now that I'm back home, I still have a lot to share! I'll be writing new journals about the science of MOSAiC every week or so, and updating photos on prior journals with ones taken during my…

#MOSAiC Expedition Update 22 October 2019 Today we traveled far enough south to see the sun rise above the horizon! People poured out onto the deck after lunch and we were treated to a beautiful…
On a recent Twitter post from the MOSAiC Expedition, they shared an image of a hole where they will deploy an ROV to study what is under the sea ice.
Life in the Ice Imagine living in a place where your home was shrinking for more than half the year, the walls literally closing in on you. For organisms living in Arctic sea ice, this is just one…
How did the team of #MOSAiCexpedition find the right floe for the ice drift through the Arctic Ocean?  [Read about here](https://blogs.helmholtz.de/polarstern/en/2019/10/mapping-floes/). Photo by Sebastian Grote
MOSAiC Expedition Update 18 October 2019 Today I had a great surprise after breakfast. I was invited to ride along on a helicopter trip and observe two buoys being set out on the ice. The helicopter…
Thin sea ice. Many different systems affect how much sea ice there is, how thick it is, and where it is located. In the Arctic, air temperature plays a major role. Photo by Dave Jones (PolarTREC 2017). Courtesy of ARCUS.
Halting the Loss of Sea Ice I just got off the satellite phone with the middle school classes in Brevig Mission, Alaska. It was really fun to talk with them about my experience and the science that…

Prepare for 'Lazy Days' Our work here with the Fedorov is nearly done. The Distributed Network is set up. Weather, skilled planning, and luck were on our side. There are a few final steps that…
Oceanographic research instrument. This CTD measures conductivity (which tells us how salty the water is), temperature, and density. It also contains sampling bottles which are closed at different depths, capturing water. The water is analyzed for things like dissolved oxygen and nutrients like nitrogen. It also can be filtered to look more closely at phytoplankton present and chlorophyll concentrations. It is an important tool for studying phytoplankton and environmental factors in the ocean.

Sugar Blobs & Stressed Out Algae The distributed network is set up! Buoys and sensors are installed in an intricate pattern for 20-30 miles around the main ice camp. We will likely circle back…
Sunset over sea ice. Tonight, the sun is setting. After it sinks below the horizon, the sun will not show itself at this northern latitude until early spring 2020. Photo by Bill Schomoker (PolarTREC 2015), Courtesy of ARCUS.
Polar Night Eve This morning, the sun rose here at latitude 85 degrees north for the last time this year. For the rest of 2019 and into February 2020 there will be no direct sunlight. The sun will…
