A team from the USGS St. Petersburg Coastal and Marine Science Center heads out into the Gulf of Mexico to check on a set of recently installed groundwater wells. These types of wells allow scientists to monitor submarine groundwater through time and quantify the flux of groundwater from Florida’s aquifer into the coastal waters of the west Florida Shelf.

50 years of teamwork. 50 years of innovation. 50 years of resilience. In 1966, Secretary of the Interior Stewart Udall announced his vision to create a program aimed at gathering facts about the natural resources of the Earth from Earth orbiting satellites. It was a bold proclamation. It was also an idea that worked and continues to work 50 years on.

The lava lake in Halema‘uma‘u, at the summit of Kīlauea, remains active. On Wednesday, June 15, a small collapse of a portion of the lake rim created a dusty plume and lake agitation, including waves that traveled across the lake surface.

Over the last few weeks, Woods Hole scientists have been mapping the seafloor of Nantucket Sound as part of a long-term partnership with the State of Massachusetts.

This timelapse sequence shows the evolution of the lava lake and rise of the crater floor in Halema‘uma‘u, at the summit of Kīlauea Volcano, since the eruption start in September 2021. Much of the the crater floor rise is driven by lava supplied beneath the surface crust. The camera is located on the west rim of the summit caldera, looking east.

Between January 14-15, 2022, volcanic eruptions destroyed much of Hunga Tonga-Hunga Ha'apai, an uninhabited island in the Tonga archipelago in the southern Pacific Ocean. A plume of ash rising 36 miles into the atmosphere blanketed the neighboring Tongan islands.

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.

The installation of thousands of rock detention structures in the Turkey Pen Watershed, of the Chiricahua Mountains in SE Arizona, provided a 30-year case study to consider low-tech and low-cost Natural Infrastructure in dryland watersheds.

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.

Ecosystems are transforming under climate change, with substantial shifts in ecological processes (e.g. fire, landscape connectivity) and important ecosystem services (e.g. pollination, water filtration) occurring at unprecedented rates.

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.
