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

Time-lapse cameras on Barter Island, North Slope of Alaska, incurred damage from polar bears who used the camera pole as a scratching post.

Otter Rock, Oregon. The Oregon coast is one of the areas that could be affected by a large earthquake on the Cascadia subduction zone.

Resurrection Bay on August 8, 2016. The water appeared calm in the shelter of the inner bay, but closer to the entrance, swells coming in from the Gulf of Alaska were breaking on a small beach where the three boaters had capsized.

The map on sheet 7 shows “potential” marine benthic habitats in the Monterey Canyon and Vicinity map area, representing a substrate type, geomorphology, seafloor process, or any other attribute that may provide a habitat for a specific species or assemblage of organisms.

Tripod deployed on the reef flat off Jurabi, Ningaloo World Heritage Site, Western Australia, with instrumentation designed to measure tides, waves, currents, and sediment being transported across the reef.

Cerulean damselfish dart around lettuce coral off the Cape Range National Park along the Ningaloo Coast in Western Australia. USGS researchers combined forces with Australian colleagues in this UNESCO World Heritage Site to conduct the most extensive study of how erosion of reefs contribute sand to the beaches—a coast’s natural armor.

A colony of the soft coral known as the "bent sea rod" stands bleached on a reef off of Islamorada, Florida. Hard and soft corals are presently bleaching- losing their symbiotic algae – all over the coral reefs of the Florida Keys due to unusually warm ocean temperatures this summer.

Physical scientist Jackson Currie steers a personal water craft (PWC) equipped with GPS and echo sounder through the waves of the nearshore area of Zmudowski State Beach in Moss Landing, California.

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.
