Tracking Pacific Walrus: Expedition to the Shrinking Chukchi Sea Ice
Summer ice retreat in the Chukchi Sea between Alaska and Russia is a significant climate change impact affecting Pacific Walruses, which are being considered for listing as a threatened species. This twelve minute video follows walruses in their summer sea ice habitat and shows how USGS biologists use satellite radio tags to track their movements and behavior.

Under Siege: Battling Flying Carp and Giant Pythons and How Science Can Help
Over the last several decades, non-native species have continued to invade sensitive ecosystems in the United States. Two high-profile species, Asian carp in the Midwest and Burmese pythons in the Everglades, are the focus of much attention by decision makers, the public and the media.

Forecast Mekong: Virtual River of Life
The Mekong is one of the world's longest rivers connecting six Asian countries, China, Myanmar, Laos, Thailand, Cambodia, and Vietnam. People and fish, as well as many other species in this biologically rich region, are directly connected to the river, so that what impacts the river also impacts them.

Cold Water Survival
In preparation for marine work in the cold waters off Alaska professionals from academia, industry and government must, every few years, take an offshore survival class to increase their chances of survival in the event of a seafaring mishap.

USGS CoreCast: Landslide Hazards
Landslides occur in all 50 states and U.S. territories, and cause $1-2 billion in damages and more than 25 fatalities on average each year. USGS scientists aim to improve our understanding of landslide hazards to help protect communities and reduce associated losses.
