Biologists measure a grizzly bear’s paw width. 

A biologist prepares to collect biological information from the bear they have captured.  Biologists collect hair samples for genetic analysis, weigh the bear,  and gather numerous measurements of the body, such as the head, paws, claws, teeth, etc.  Overall condition of the bear is assessed as well, including a body fat measurement.

Biologists have immobilized the bear and prepare to lift it out of the trap and onto the tarp for data collection.  Once on the tarp the bear is easier to move. 

Once a grizzly bear is radio collared, biologists can track its movements with telemetry via airplane.  The IGBST also used the latest telemetry technologies, which allows downloading of GPS data from the radio collar via satellites.

Once a grizzly bear is radio collared, biologists can track its movements with telemetry on foot.

A ship will tow this green cable, which contains underwater microphones that record sound reflected off layers beneath the seafloor. USGS scientists will use the data to pinpoint the location of faults.

USGS geologist Jamie Conrad uses a map of the seafloor off Southern California to plan high-resolution mapping southwest of Santa Catalina Island. Small inset shows seafloor data collected by the ship that reveals hills, gullies, and basins.
