Dead and dying mangrove trees in shallow water

The lasting impact of Hurricane Irma, which struck in September 2017, is apparent at Jim Foot Key in Florida Bay, Everglades National Park, on April 26, 2019. The island has lost many mangroves and water from Florida Bay now covers the island’s interior mudflats. (Credit: B. Stackhouse, USGS. Public domain.)

Scientists drill a piston core in Florida Bay sediment

Christopher Bernhardt, James Murray, Bethany Stackhouse and Terry McCloskey, USGS, collecting a piston core on Bob Allen Key in Florida Bay, Everglades National Park, April 14, 2014.  Piston cores can be labor intensive, and capture about 1.5 meters of the island’s carbonate mud, or about 3500 years of the sediment record. (Credit: Lynn Wingard, USGS.

Gif shows a time-lapse of lowering a yellow lander into the ocean from the side of a ship

In this time-lapse, one of the University of North Carolina landers is deployed over the side of the R/V Falkor into the water. From there, it will sink to the seafloor. Once it has reached the bottom, ROV SuBastian will be deployed to reposition the lander to the desired location. (Credit: Shelton Du Preez, Schmidt Ocean Institute.

USGS scientist samples an ocean sediment core

USGS scientist Summer Praetorius collects samples from an ocean sediment core in the Pacific Ocean Paleoclimatology Lab at Menlo Park, California. The sediment core is from Tanner Basin, located about 200 miles due west of San Diego in the eastern Pacific Ocean. This area is the southern-most extension of the California Current upwelling system, which brings cold nutrient-rich waters from the deep into the surface ocean and drives rich California marine ecosystems, such as the iconic kelp forests. The kelp forests are hotspots for marine biodiversity, major fisheries, and provide other critical ecosystem services, such as wave mitigation and protection against coastal erosion. Studies of this sediment core will yield information about past sea surface temperatures, phytoplankton abundance, and ocean circulation that will be used to better understand the future of California’s vital marine resources.
