A new study shows that icebergs may initiate submarine landslides when they collide with the seafloor.
Icebergs
Satellite Captures Detaching Iceberg in Near-Real Time
NASA’s ICESat-2 satellite recorded the cleaving of a 315-billion-ton iceberg from Amery Ice Shelf in 2019, as well as years of subtle cracking and splitting prior to the calving event.
“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.
“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.
Small Seismic Signals Tell a Story of Iceberg Calving
Seismic signals detected hundreds of kilometers away from Greenland glaciers reveal the calving style and iceberg size.
Seasonal and Annual Changes in Pitch in Blue Whale Calls
Six years of acoustic recordings detect seasonal shifts in blue whale vocalizations that correlate with the presence of icebergs, a primary source of ambient ocean noise in the southern Indian Ocean.
Creating Icebergs in Ocean Models Coupled to Ice Shelves
Modeling icebergs as Lagrangian elements held together by numerical bonds provides insights into coupled exchanges of heat, freshwater, and momentum between large icebergs and the ocean.
Icebergs Reveal Contours of the Ocean Bottom
Using satellite imagery of grounded icebergs near Greenland, researchers estimate the drafts of these ice masses and therefore water depth, measurements that shed light on future sea level rise.
Scraping Bottom: Iceberg Scours Reveal North Atlantic Currents
A 3-D seismic analysis of Pleistocene iceberg gouges indicates that surface currents in the Norwegian Sea flowed northward and remained consistent during numerous glacial cycles.
How to Find an Iceberg’s Breaking Point
Researchers develop a mathematical method of modeling tabular icebergs, like the one that broke away from an Antarctic ice shelf earlier this year.
