Scientists process sediment cores from the deep sea

To help study the biodiversity present in the deep sea, scientists collect sediment cores. These cores are about a foot long and provide a vertical profile of deep-sea sediment, or mud. USGS scientists at the Wetland and Aquatic Research Center identify and quantify the tiny animals found

Red plumes burst out from the tops of these chemosynthetic tubeworms

Red plumes burst out from the tops of these chemosynthetic tubeworms, capturing hydrogen sulfide and oxygen from the surrounding water to feed their bacterial endosymbionts. The tubeworm tubes provide a habitat for several benthic animals, including the pale pink branching octocorals seen here

Red Sea Urchins

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. Read more about the cruise and its
