Female Pacific walruses and their calves traditionally spend summers far from shore, diving for benthic invertebrates over the shallow continental shelf waters of the Chukchi Sea. These female walruses and their calves prefer to rest between forage bouts on sea ice drifting above their feeding grounds.

(Aug 19, 2006, 00:00:33 to 01:40:33) To document changes in the lava stream level within the PKK lava tube, a time-lapse camera was placed at the edge of the informally named "Kelly's" skylight. The camera recorded several abrupt and short-lived increases in lava stream level that eventually sealed the skylight shut.

In this episode we explore how scientists for the USGS National Water Quality Assessment Program investigate the ecological health of rivers and streams across the United States. Focusing on a recent sampling effort along the Minam River in northeast Oregon, this video highlights USGS sampling methods for fish, macroinvertebrates (bugs), algae, and habitat.
