Elkhorn coral on a USGS calcification-assessment station in Dry Tortugas National Park

Established in 2009, the U.S. Geological Survey’s Coral Assessment Network (USGS-CAN) provides data on coral-growth (calcification) rates throughout the Florida Keys. Pictured here is one of 30 stations located in in Dry Tortugas National Park. The data document seasonal and spatial patterns in coral growth that correlate with ocean conditions and are used to guide the management and restoration of coral species that have experienced population declines across the region. Shown here is the threatened Elkhorn coral, Acropora palmata, that is largely responsible in the western Atlantic for creating the reef-crest habitat, the shallowest zone of the reef where waves break, that is essential for shoreline protection.

Acoustic Telemetry Used to Track Fish

Staff from the USGS Great Lakes Science Center gaze at the Mackinac Bridge rising above the mist in the Straits of Mackinac, Michigan. The lines they are holding are attached to grappling hooks being used to retrieve acoustic telemetry equipment anchored on the bottom of the straits. The equipment is used to track fish movements in the Great Lakes and was deployed as part of the Great Lakes Acoustic Telemetry Observation System (GLATOS) network.
Scientists have been implanting Great Lakes fish with transmitters and, like the GPS on a car, tracking fish movement through a network of receivers placed at the bottom of the lakes. The information collected from this equipment helps scientists understand fish behavior in relation to Great Lakes ecology and provides information useful to fish managers in their decision making. (Credit: Brad Buechel, USGS.)
