Two red sea urchins (Mesocentrotus franciscanus) sit on the deck of the R/V Falkor. These sea urchins were collected during the #HuntingBubbles research cruise led by the USGS and Schmidt Ocean Institute, which focused on exploring and understanding methane seeps and the communities that depend on them along the Cascadia Margin.

Marine geochemist Renee Takesue collects a sample of exposed mud in a marsh near Sonoma Creek, California. She will look here and in nearby San Pablo Bay for chemicals from the 2017 Nuns Wildfire that can harm wildlife. The stormy winter of 2018 may have transported these contaminants from the Sonoma Creek watershed into San Pablo Bay National Wildlife Refuge.

A USGS scientist surveys GPS Ground Control Point locations on North Topsail Beach and within the Camp Lejeune Marine Corps Base, North Carolina. These data are used to validate previously surveyed aerial imagery and aid in Structure from Motion (SFM) processing. Specifically, this scientist was collecting data to look at coastal change due to Hurricane Florence.

Lukas Winkler-Prins checks on the frame setup on June 10, 2019. This tripod has an RBR CTD, an RBR bursting pressure sensor, an RBR optical backscatter sensor, a LISST-200X, an altimeter, and two Nortek ADVs + Seapoint optical backscatter sensors, which will reveal information about water temperature and salinity, wave height and period, total s

USGS studies the growth rates of corals at a network of coral growth assessment stations throughout Buck Island National Monument in St. Croix, U.S. Virgin Islands. These data provide resource managers with information needed to understand how coral populations are doing in the park.

The USGS Pacific and Coastal Marine Science Center collected data to investigate sediment dynamics in the shallows of San Pablo Bay in two deployments: February to March 2011 (ITX11) and May to June 2012 (ITX12). This data release includes time-series data and grain-size distributions from sediment grabs collected during the deployments.
