Brain coral spawning coral larvae. The larvae will settle on other surfaces and grow into new coral in a process called recruitment.

Map showing the surficial geology of Vineyard and western Nantucket Sounds with equivalent onshore geology (adapted from Stone and DiGiacomo-Cohen, 2009). The areal extents over which offshore subsurface geologic units crop out at the sea floor were interpreted from seismic-reflection data.

Jen Suttles,Woods Hole Coastal and Marine Science Center, collects water samples from a salt marsh tidal creek (East Falmouth, MA) for laboratory analysis of total organic carbon. These samples will be compared to data recorded by instrumentation deployed in an adjacent tidal creek as part of research efforts to quantify carbon dynamics in coastal ecosystems

Current CoSMoS coastal hazard forecasts cover southern California, from Santa Barbara County in the north to San Diego County in the south.

USGS scientist Sara Zeigler records habitat characteristics in iPlover at an ‘exclosed’ nest. On some beaches, managers erect netting around nests to protect eggs/chicks and adults from predators, allowing movement of chicks and parents to and from the nest but excluding predators

Groundwater data were collected in the spring and fall of 2008 from three sites representing different geological settings and biogeochemical conditions within the surficial glacial aquifer of Long Island, NY.

Sandy Brosnahan performing first solo flight as a USGS certified drone pilot.  There are multiple exciting applications for drone imagery including erosion studies and physical changes to coastal ecosystems over time. 

Seafloor offshore of Point Estero (PE) showing east (EH) and west (WH) strands of the Hosgri fault zone. Arrow points to a seafloor slope (a 12,000 year old shoreline) that has been offset by the east Hosgri strand, indicating a slip rate of about 2.6 millimeters per year.

Large submarine slides off southern California (outlined in small white dots). Low-resolution bathymetry shown in light grey (approximately 100 meters/pixel). High-resolution bathymetry shown in darker grey (less than 20 meters/pixel).

Researchers survey Elwha River elevation and depths. Clockwise from upper left: setting up a traditional survey instrument above the river; measuring river depths from a kayak with sonar and GPS; walking the beach with GPS backpacks; and determining offshore depths using a personal watercraft with GPS and sonar.

Schematic showing how sediment on the seafloor moves in response to a force created by the combined action of tides, ocean waves, and wind-driven currents.
