Erin Pettit: Glaciologist, Artist, Mentor
Between research trips to Antarctica and the Arctic, Pettit regularly leads art- and science-focused wilderness expeditions for young women.
“Terremotos Glaciales” Vistos por Primera Vez en Thwaites
Estos eventos sísmicos, provocados por los icebergs que se vuelcan y chocan contra Thwaites, revelan que el glaciar ha perdido parte de su plataforma flotante de hielo.
Precipitation Plays a Key Role in Glacial Erosion
After comparing the climatic conditions at dozens of glaciers worldwide, researchers find that precipitation, not temperature, is the leading environmental factor driving glacial erosion.
The Threat at Thwaites
This Antarctic glacier is rapidly losing mass. An international team is digging into the ice to figure out just how bad it is.
“Glacial Earthquakes” Spotted for the First Time on Thwaites
These seismic events, triggered by icebergs capsizing and ramming into Thwaites, reveal that the glacier has lost some of its floating ice shelf.
First Field Observations of Ocean Melting a Tidewater Glacier
Using autonomous kayaks, researchers carried out measurements of water properties near the terminus of LeConte Glacier and showed that ice/ocean interactions are more complex than thought.
Southern California Climate Change over 100,000 Years
Researchers used a sediment core from a lake in California’s San Bernardino Mountains to track the effect of climate on vegetation, fire, and erosion between about 120,000 and 15,000 years ago.
Seeing the Greenland Ice Sheet Through Students’ Eyes
A team of students and faculty advisers revisited the site of pioneering geosciences expeditions from the 1920s, looking to introduce young researchers to polar science.
An Ice Sheet’s Footprint on Ancient Shorelines
Researchers combine observations of ancient shorelines and properties of Earth’s crust to infer the size of the Laurentide Ice Sheet during the last glacial cycle.
