The Pacific Walrus is particularly drawn to the pr The Pacific Walrus is particularly drawn to the productive seafloor for its food sources (clams and other benthic invertebrates) in the Chukchi Sea during summer months. 
.
Odobenus rosmarus divergens (Odobenus means “tooth-walker”) was petitioned for listing as a threatened species (under the US Endangered Species Act) in 2008 because of climate warming and sea ice decline.
.
Walrus calves are born in late April/early May and are ~140 pounds and tuskless at birth. Who sees the newborn walrus popping her head up at the end?

Measuring light transmittance through the ocean wa Measuring light transmittance through the ocean water column requires a straight (up and down) wire angle, which sometimes means a little shimmying is necessary to keep things straight as the ship is moved by wind and/or currents.

We had a full slate of successful science this sum We had a full slate of successful science this summer!  Our collaborations with the University of Maryland Center for Environmental Science, US Fish and Wildlife Service, Institute of Ocean Sciences/Fisheries and Oceans Canada, and the University of Victoria allow us to understand the impacts of seawater warming and sea ice decline (due to climate change) on marine ecosystems at biological hotspots across a broad latitudinal gradient in the Pacific Arctic. Huge thanks to the crew onboard the CCGS Sir Wilfrid Laurier for the spectacular support!

Huge congratulations to Abby Beilman who just succ Huge congratulations to Abby Beilman who just successfully defended their M.S. thesis in Environmental Science & Policy: “Changes in Chromophoric Dissolved Organic Matter in the Blackstone River Watershed: Drivers and Implications for Climate Change”.
.
Please join me in congratulating Abby, who did an absolutely outstanding job!!
.
Abby will leave Clark with both a B.A. degree (Environmental Science/Earth System Science major, Political Science minor) and an M.S. degree (Environmental Science & Policy) in only five years through our Accelerated Degree Program. Abby is now headed to the Ph.D. program at Michigan State University. Congratulations Abby, you are a superstar!!

Traveling all the way from the Arctic Ocean to Cla Traveling all the way from the Arctic Ocean to Clark University in Worcester, Massachusetts, our samples allow us to measure the amount of chlorophyll in ocean waters. This tells us how much algae is in the ocean at different depths, which in turn gives us insight into how the whole ecosystem is functioning.

Today the 18th edition of the Arctic Report Card w 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.
.
The photo is a throwback to the Arctic Report Card release in 2022 when I had the privilege to serve on the press panel at AGU along with NOAA administrator Dr. Rick Spinrad and others. 📷 (2) Monica Allen (NOAA)

Thrilled to have @chrislinderphoto speak in my und 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!
