Salt levels in ice cores tell stories of ocean conditions past
Salt levels in an ice core drilled at the South Pole are telling scientists what Antarctic sea ice conditions were like in the past. This information is crucial to understanding how the continent will fare in a changing climate.

On the Wings of Petrels
While penguins may be viewed as the iconic Antarctic bird, there are many other species that call the continent and Southern Ocean home. As part of NSF's Long Term Ecological Research (LTER) project, a group of scientists are looking at the bird species along the Western Antarctica Peninsula.

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: The Paris Climate Agreement and future sea-level rise from Antarctica
The world is currently on track to exceed three degrees Celsius of global warming, and new NSF-funded research led by researchers at the UMass Amherst shows that such a scenario would drastically accelerate the pace of sea-level rise by 2100. However, the paper reveals that there still appears to be an opening for humankind to collectively reduce greenhouse gas emissions to prevent this mid-century acceleration in sea-level rise.

NSF Blog: The Glacier of Greatest Concern
Antarctica's massive Thwaites Glacier is melting and its collapse could raise sea levels significantly around the world. Through the International Thwaites Glacier Collaboration, the National Science Foundation (NSF) and the U.K. Natural Environment Research Council have teamed up to send scientists to the remote region by land, sea and air to study every aspect of the glacier.

New Pier to be Constructed in 2021-2022 at Palmer Station
The National Science Foundation is moving ahead with plans to rebuild the pier at Palmer Station, its research facility on Anvers Island, Antarctica. The new pier will be more than three times larger than the current one, extending farther out from the station into deeper water to allow the mooring of larger ships.
