This video podcast looks at the science behind understanding coastal vulnerability and hazards posed by extreme storms. It documents how USGS scientists study the response of coastal environments to the extreme winds, waves, and currents brought by such storms.

How do you catch a sea otter? Very carefully. Researchers must use high-tech equipment and teamwork in order to safely capture these marine mammals and collect blood samples and conduct health exams as part of the Pacific Nearshore Project.

American and Canadian scientists head north on a collaborative expedition to map the Arctic seafloor and gather data to help define the outer limits of the continental shelf. Each coastal nation may exercise sovereign rights over the natural resources of their continental shelf.

movie shows video taken during today's field visit and overflight. The first portion of the video is taken at the rim of Pu`u `Ō `ō crater, and shows the north vent feeding the lava pond. The lava surface undulates due to rising gas bubbles, and a small overturn is triggered.
