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.

Critical to scientific operations aboard the Escanaba Trough expedition are 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.

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.

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.

Coastal wetlands are among the most productive and valuable ecosystems in the world—comparable to even rainforests and coral reefs.

The Arctic region is warming faster than anywhere else in the nation. Understanding the rates and causes of coastal change in Alaska is needed to identify and mitigate hazards that might affect people and animals that call Alaska home.

The increasing risk of flooding along our coasts is driven by climate change, development and habitat loss.

During a recent dive on the New England Seamount chain off the North Atlantic coast, researchers aboard the NOAA Ocean Exploration Expedition, North Atlantic Stepping Stones, discovered a marine geological feature known as a ferromanganese (Fe-Mn) nodule field in the saddle between two peaks of Gosnold Seamount.
