After recovery, the jumbo piston corer sits on the deck of research vessel Bold Horizon in its launch and recovery system. This muddy collar is removed to reveal the removable length of the core, which sits within a stiff plastic tube inside the metal tube.

USGS marine technician Jenny McKee prepares the jumbo piston corer for launching off research vessel Bold Horizon off the coast of California and Oregon. The corer will collect sediment samples from the seafloor. Scientists will examine the sediment to determine its age, character, and distribution. This area off the west coast of the U.S.

Dr. Nora Nieminski is a research geologist and Mendenhall Fellow at the USGS Pacific Coastal and Marine Science Center in Santa Cruz, California. She is pictured here, on board Marine Vessel Bold Horizon, with a piston core sample collected from the southern Cascadia subduction zone offshore of northern California/southern Oregon.

Goleta Beach in Santa Barbara experienced an unusual storm and large wave event in the Spring of 2014. Gaviota Pier, seen far off in the background, sustained heavy damage as did the restaurants on the pier and nearby. The USGS conducts seasonal surveys throught the year to see how the beaches are changing through time.

These “pom-pom” anemones (Liponema sp.) have attached to the rock in a place where there are probably very good currents, which bring small floating particles of food to them. Water depth is 1041 m (3415 ft).

Example of a low-oblique photograph taken with an unmanned aerial system (UAS), or drone, of the coastal bluffs of Barter Island on North Slope of Alaska. The photographs from different time periods can be compared, using a technique called structure-from-motion photogrammetry, to measure changes in the coastal bluffs.

Example of a thermal photograph of Barter Island's bluffs, on the North Slope of Alaska. Two USGS scientists stand waving on the right side of the photo. Lighter areas are warmer, darker areas are colder. Thermal photography makes it easy to detect areas of permafrost, or the lack thereof.
