Seagrass Beds and Manatee Foraging Areas in the Ten Thousand Islands: Mapping and Characterizing by Incorporating Manatee GPS Tracking Data and Habitat Information

Turbid water conditions make the delineation and characterization of benthic habitats difficult by traditional in situ and remote sensing methods. Consequently, only a small fraction of this valuable resource has been mapped or characterized.

The Oysters of Chicopit: Status of the Oyster Population in Chicopit Bay before, during, and after the Construction of the Mile Point Project

Chicopit Bay, part of the Timucuan Ecological and Historic Preserve in Florida, is a small embayment at the intersection of San Pablo Creek (part of the Intercoastal Waterway) and the St. Johns River. Home to a number of small oyster beds, this area is now being dredged to help eliminate cross currents from the main shipping channel of the St. Johns. WARC researchers collect baseline...

Winter Manatee Foraging Behavior and the Decline of Seagrass Beds in the Northern Indian River Lagoon

With high numbers of manatees using the Florida Power and Light power plant warm water refuge during winter, their impact on the seagrass beds in the Indian River Lagoon is considered an important indicator of the long-term capacity of the area to support the manatees. USGS is working with partners to investigate the spatial extent and intensity of manatee use of seagrass beds in the area. ...

NRDA: Deepwater ROV Sampling to Assess Potential Impacts to Hardbottom Coral Communities and Associates from the Deepwater Horizon Oil Spill

The MC252 oil spill introduced hydrocarbons, dispersants, and drilling muds into the Gulf of Mexico, potentially adversely affecting the seafloor environment surrounding the spill site.

USGS DISCOVRE: Benthic Ecology, Trophodynamics, and Ecosystem Connectivity – Lophelia II: Continuing Ecological Research on Deep-Sea Corals and Deep Reef Habitats in the Gulf of Mexico

Deep-sea coral habitats are complex ecosystems at the landscape and local level. While these systems may harbor substantial levels of biodiversity, they remain inadequately investigated.

Exploration of Caribbean Seamounts within the Greater and Lesser Antilles (GA/LA) Transition Zone: Characterization of the Benthic Ecology and Geology

Seamounts may be biodiversity hotspots, oases, islands, and centers for endemism in the deep sea. USGS and partners explore these possibilities within the Greater and Lesser Antilles Transition Zone.

Integrative Studies of Florida Spring Ecosystems

Florida's springs are a source of cultural, recreational, and ecological importance. But land-use changes and increased demands for groundwater due to the state's growing population have led to widespread impairment of these unique ecosystems.
