Escanaba Trough Expedition: Biological Communities
Detailed Description
The familiar saying “good things come in small packages” holds especially true for deep-sea biological communities at hydrothermal vents, including those at Escanaba Trough, a seafloor spreading center located almost 200 miles off the northern California coast.
In these deep, dark environments, where energy comes not from the sun but from hydrothermal chemicals, microbes form the base of a chemosynthetic food web.
Microbes convert hydrothermal chemicals into energy. They form a symbiotic relationship with creatures such as tubeworms and clams, dwelling in their tissue and providing food for them in exchange for a place to live.
USGS scientists want to understand how deep-sea communities change over the life cycle of hydrothermal systems, as active venting sites cool down or stop flowing, turning to inactive sulfide mounds and eventually becoming background, deep-sea environments.
By both revisiting historic sites and investigating new ones at Escanaba Trough, scientists seek to understand how these communities change over space and time, linking those patterns to the underlying hydrothermal environment.

Seafloor features such as sulfide mounds and chimneys are prominent evidence of hydrothermal activity. These features, whether active or dormant, are just the tip of the iceberg, so to speak; much of the “plumbing” of hydrothermal systems exists beneath the seafloor surface.

For scientists aboard the Escanaba Trough expedition, obtaining sediment cores or deep-sea biological and geological samples after a Jason dive is only the beginning.

Critical to scientific operations aboard the Escanaba Trough expedition is the submersible robots Sentry and Jason. Owned and operated by the Woods Hole Oceanographic Institute (WHOI), these robots allow researchers to observe seafloor features and collect data from depths seldom visited by humans.

Embarking on a three-week deep-sea research expedition requires a lot of preparation. For this expedition to Escanaba Trough, U.S. Geological Survey scientists and partners spend the first few days in port, building their laboratory space aboard the research vessel Thomas G. Thompson.
