Fig. 11. Conceptual diagram illustrating past conditions vs. present conditions in the marginal ice zone west of the Antarctic Peninsula in the spring season (October to November). Spring conditions are inherently light-limited due to low solar zenith angles (SZA). Past conditions with lower wind speeds and shallower mixed layer depth (MLD) provided more favorable conditions for spring surface phytoplankton accumulation compared to present conditions.

New paper on changing phytoplankton phenology along the Antarctic Peninsula

In a recent paper, Jessica Turner, a PAL collaborator and Postdoctoral Associate at the University of Connecticut, found that phytoplankton blooms are starting later rather than earlier over time, likely driven by increased wind mixing. Her…

Earth Day with Scott Doney

For Earth Day this year, PAL Co-PI Scott Doney was featured on the University of University of Virginia's podcast Hoos in STEM. In the episode “Celebrating Earth Day with Environmental Scientist Scott Doney,” Scott sat down with…
Fig. 3. Photos of example items found (A) A 185 mL bottle of Bona Forte fertilizer for houseplants (in Russian), (B) 100 mL metal bottle of Ethylchloride for pain relief (in Spanish) (left) and an unidentifiable metal bottle (right), (C) what appears to be a Dunlop Mens Purofort Thermo Wellington Boot, which is steel toe and protects under cold conditions, (D) estimated 40 lbs. of line, buoy (~ 2 m diameter) and cloth/mesh (note the human for scale), and (E) a Master Kong plastic water bottle cap (in Chinese). All items pictured were found in the Joubins Islands with BCE, A, and D on island 76, 12 and 18, respectively.

New Paper on marine debris found near Palmer Station

In a new paper,  Katherine Gallagher, Gina Selig, and Megan Cimino document their recent observations of marine debris around Palmer Station in Antarctica. Last season, they found 135 pieces of marine debris along the shore, and near the…

Looking Forward: The Race to Save Antarctic Penguins

The penguin populations in Antarctica are rapidly changing due to the effects of climate change. Over the past 30 years, scientists have studied the penguins around Palmer Station along the West Antarctic Peninsula, and have observed a significant…

Joy Ferenbaugh appointed Assistant Professor

Congratulations to Joy Ferenbaugh, who was recently appointed as an Assistant Professor of Biology at Adams State University in Colorado. Joy was previously a PAL post-doctoral scholar, working in Scott Doney's Computational Biogeochemistry…

Upside Down Ocean: Unraveling the Crisis of Antarctic Sea Ice

Climate change is having a dramatic effect on Antarctic sea ice. For years, ice around the continent seemed oddly consistent, while sea ice in the Arctic has declined dramatically. But that is no longer the case. Over the last few years,…

New Paper: 60 years of glacial retreat behind Palmer Station

In a new short paper, Megan Cimino, Marissa Goerke, and Shavonna Bent document how the Marr Glacier behind Palmer Station has retreated over the past 60 years. They found that the glacier has retreated about 7.7 meters per year, which…
Antarctic Sea Ice Sees Record Low Growth

Fast Company on the Five-Sigma Event

Earlier this summer (for those of us in the northern hemisphere), as Antarctica reached it's peak winter season, scientists observed what came to be known as a "five-sigma event" in Antarctic Sea Ice. This referred to the unprecedented…

Associated Press: Antarctic Krill Fishing

This month, PAL LTER scientists Deborah Steinberg, Logan Pallin, Ari Friedlaender, and Joe Cope were featured in a story by the Associated Press. Factory fishing in Antarctica for krill targets the cornerstone of a fragile ecosystemBy Joshua…

Lightning Talk on Palmer LTER Science

PAL PI Dr. Oscar Schofield recently gave a lightning talk on the current status of the Palmer Station LTER at the 2023 LTER Science Council Meeting. Check it out below. https://www.youtube.com/watch?v=3OyvCll7HDY&list=PL48B_zTeq86…

Palmer penguins featured on WHYY’s The Pulse

In April, the podcast series The Pulse from WHYY in Philadelphia featured an episode about Taking the Temperature of Climate Science. One segment featured our own Megan Cimino and her work studying the Adélie penguin population around Palmer…

New Paper: Remote sensing of sea surface glacial meltwater on the Antarctic Peninsula shelf

As the glaciers in Antarctica and especially along the West Antarctic Peninsula melt, it is important to understand where the meltwater is going, and how it will affect the oceanic ecosystem. In the latest issue of Frontiers in Marine Science,…
