Today the 18th edition of the Arctic Report Card was released by the National Oceanographic and Atmospheric Administration (NOAA) at the American Geophysical Union (AGU) meeting in San Francisco. The report highlights the major environmental changes the Arctic experienced over the past year, including that 2023 was the Arctic’s warmest summer on record.
.
My contribution to the report (along with my co-authors) was to document the increasing phytoplankton (algae) blooms in the Arctic Ocean owing to warming seawaters and sea ice decline.

Thrilled to have @chrislinderphoto speak in my undergraduate course The Arctic in the Anthropocene today! So incredibly insightful to hear about ways we can communicate about climate change through photography. And of course always such a treat to see some of the best photos you’ll ever see of science in the polar regions!

Meanwhile, in the room next door to the CTD garage

Meanwhile, in the room next door to the CTD garage, scientists congregate to watch the water column data in real time, fill out sample labels, and get a sneak peek of the environmental conditions at each science station. Paige Hagel (Fisheries and Oceans Canada) communicates to the crew (who are controlling the CTD with a winch) via radio what depths to stop at for water sampling.

The CTD (that measures Conductivity, Temperature, and Depth, among other critical oceanographic variables) is usually one of the first scientific instruments in the water at each science station. It is typically accompanied by a rosette of Niskin bottles that collects water at various depths that are sampled from once back on board the ship platform.

Huge congratulations to Abby Beilman, who just successfully defended their senior honors thesis: “Changes in Chromophoric Dissolved Organic Matter in the Blackstone River Watershed from Summer to Fall Driven by Hydrological Shifts”. Abby will graduate with their BA degree (Environmental Science/Earth System Science major with a Political Science minor) next month in May 2023.
.
Please join me in congratulating Abby on a fantastic job, they put so much hard work into this project!!

Repost from @clarkuniversity - Clark University ge

Repost from @clarkuniversity - Clark University geographer and @clarkpolarscience professor Karen Frey understands that when people think of the #Arctic, they typically envision “a really desolate, cold, white place.” But the Arctic Report Card, to which she has contributed since 2011, predicts a warmer, wetter, stormier, and greener Arctic than previously imagined.

One of 147 scientists from 11 nations who worked on this year’s report, Frey focuses on changes to phytoplankton — microscopic marine algae in Arctic Ocean seawaters, sometimes known as “the forests of the sea.”
