Map view. Colored shaded-relief bathymetry map of Monterey Canyon and Vicinity map area, generated from multibeam-echosounder and bathymetric-sidescan data. Colors show depth: reds and oranges indicate shallower areas; purples, deeper areas. Illumination azimuth is 300°, from 45° above horizon.

USGS ocean engineer Gerry Hatcher with the camera system he helped create for recording the precise time and geographic location of each air photo it takes. The system is mounted in the cargo compartment of a Cessna 182R airplane and takes photos through a window cut into a removable cargo door (right).

On October 6, 2016, scientists lower an instrument package on a taut-wire mooring into the canyon. The sediment trap (long funnel-shaped device) is designed to capture mud and sand carried in turbidity flows; the other sensors measure currents and suspended sediment.

Sediment trap is being prepared for deployment into Monterey Canyon offshore of Monterey, California.

Six USGS scientists presented their research at the 6th International Symposium on Deep-Sea Corals in September, 2016. This all-female force hailed from USGS centers in West Virginia, California, and Florida.

USGS is studying climate change impacts to U.S. Pacific and Arctic coasts. Alaska’s north coast is predominantly erosional, retreating on average about 1.4 meters per year.

USGS geologist Amy East was delighted to observe a Chinook salmon carcass upstream from two dams recently removed from the Elwha River in Washington State. River restoration has allowed salmon to reach upstream spawning grounds for the first time in more than a century.

Two scientists on the Arctic coastal bluff preparing a study location with cameras that they hope will run continuously, collecting images.

Christie gears up to survey beach elevation in Santa Cruz, CA with a precise and accurate GPS unit mounted to her backpack. The GPS unit on her backpack communicates with a nearby "base station" to minimize errors in location.

During the symposium, participants could tour the facilities at Woods Hole Oceanographic Institution, such as this radiocarbon lab. Here scientists analyze the amount of radiocarbon in such material as coral or wood to help determine their age. Photo credit: Amy West, USGS Pacific Coastal and Marine Science Center
