Sea Level Rise and Climate: Impacts on the Greater Everglades Ecosystem and Restoration

The Greater Everglades Ecosystem covers much of south Florida, and the highest areas are only a few meters above sea level.  Predictions of sea level rise and changes in storm intensity for the 21st century are particularly concerning to the urban population of Miami and the east coast, but also represent a challenge to Everglades National Park and Biscayne National Park resource...

Coral Reef Ecosystem Studies (CREST)

The specific objectives of this project are to identify and describe the processes that are important in determining rates of coral-reef construction. How quickly the skeletons of calcifying organisms accumulate to form massive barrier-reef structure is determined by processes of both construction (how fast organisms grow and reproduce) and destruction (how fast reefs break down by mechanical...

The long-term effects of Hurricanes Wilma and Irma on soil elevation change in Everglades mangrove forests

Mangrove forests in the Florida Everglades (USA) are frequently affected by hurricanes that produce high-velocity winds, storm surge, and extreme rainfall, but also provide sediment subsidies that help mangroves adjust to sea-level rise. The long-term influence of hurricane sediment inputs on soil elevation dynamics in mangrove forests are not...
