Update: R/V Nathaniel B. Palmer in the Amundsen Sea
The USAP research vessel Nathaniel B. Palmer has now reached the Amundsen Sea off West Antarctica and has begun its planned investigation of the Dotson Glacier as part of the International Thwaites Glacier Collaboration. However, the extent of sea ice is proving to be heavy this season with multi-year ice making movement around the region challenging.
Research Update: Baleen whale prey consumption based on high-resolution foraging measurements
A new study shows that baleen whales once annually consumed 430 million tons of Antarctic krill.
Research Update: A Recirculating Eddy Promotes Subsurface Particle Retention in an Antarctic Biological Hotspot
A recent study has shown that a subsurface element impacts the creation of the Palmer Deep Canyon hotspot.
Research Update: Within an Antarctic Sea Squirt, Scientists Discover a Bacterial Species With Promising Anti-Melanoma Properties
Compounds found in Antarctic sea squirts may have medicinal and biotechnological applications useful to humans in science and health.

Celebrating three decades of the Albert P. Crary Science and Engineering Laboratory
The largest research lab in Antarctica celebrates 30 years since its dedication.
Shrinking sea ice habitat is impacting the population of emperor penguins in Antarctica
Decades of research on emperor penguins may lead to their listing as 'threatened' under the Endangered Species Act.
Research Update: NSF-funded research explores how dissolved organic carbon drives ocean health
Organic carbons are critical support for oceanic food webs. But changes in the climate can impact sensitive marine systems.
Research Update: Impact of subcolony-scale nesting habitat on breeding success of Adelie penguins
In Antarctica, researchers are trying to understand the nest success differences in Adelie penguin colonies at Cape Crozier and Cape Royds.
RESEARCH UPDATE: Researchers Use Ice-Penetrating Radar to Better Understand Antarctic Glaciology
A recent publication from NSF-funded research by scientists at UC Santa Cruz has examined how electrical conductivity, and not radar reflectivity alone, should be used in investigating subglacial materials.
RESEARCH UPDATE: Young Weddell seals need to practice navigating before hunting
According to a new NSF-funded study from California Polytechnic State University, Weddell seal pups may be one of the only types of seals to learn to swim from their mothers.
RESEARCH UPDATE: Marine ice-cliff instability at the West Antarctic Ice Sheet
The West Antarctic Ice Sheet (WAIS) holds enough ice to raise global sea levels by about three meters. The ice sheet is also vulnerable to rapid retreat through a process called marine ice-cliff instability (MICI).
RESEARCH UPDATE: Ice core chemistry expands insight into sea ice variability
Recent work has been published by scientists from the University of Maine, giving insight into the seasonal and overall changes in sea ice in the Southern Hemisphere. Using ice core samples from the South Pole, researchers looked at the ice's chemistry, and particularly sea salt concentrations.
