Linking Irma storm signatures to the Holocene sediment record for South Florida- Lynn Wingard

South Florida’s proximity to sea level makes Miami and the Everglades ecosystem vulnerable to storm surge. Sediment cores document past rates of sea level rise, but past storm signatures are difficult to identify. Development of modern calibration datasets will provide information to interpret past storm records and help urban planners and resource managers prepare for the future.

Fighting the Tide: Combating Coral Disease and Disappearance Within the Florida Reef Tract Using Models- Daniel Walsh

In an unprecedented large-scale mortality event, Florida has lost >90% of many coral species. This event is unusual due to its expansive spatial extent, the number of affected species (at least 21 scleractinian coral species), and severity of losses (> 95% for Dendrogyra cylindrus), effectively eliminating some species from the tract.

Examining controls on the solubility in the ocean of iron from dust and volcanic ash- John Crusius

Biological productivity in the Gulf of Alaska is limited by availability of the micronutrient iron. Dust derived from Alaskan glacial flour and from Asian deserts, and ash from Alaskan volcanoes, episodically supply iron from the atmosphere. This internship would carry out studies on archived material from a variety of dust and ash samples to examine controls on the supply of this micronutrient.

Response of a tidal brackish marsh to global change drivers: an ecosystem level manipulation of warming and elevated carbon dioxide- Glenn Guntenspergen

The USGS and the Smithsonian Institution have initiated the first in situ active aboveground and belowground warming experiment in a coastal wetland that is focused on wetland temperature responses and also examines the interaction between warming, elevated CO2, and inundation frequency on wetland resilience in the face of changes in global change drivers.

Long-term trends in forest regeneration across drought and salinity gradients in the northern Gulf Coast- Beth Middleton

Relict forests are becoming more common as as climates become hotter, drier and more saline. The first sign of threat to these forests is a chronic lack of seedling and sapling recruitment. This project will help pinpoint forests at risk to help in future management.

Improving Models of Coastal Change- Chris Sherwood

Help improve models of coastal erosion and morphologic change! This project offers an opportunity to collect and process various kinds of oceanographic and morphologic data using instruments and images recorded with our beach cam and drones. Or it can be a chance to develop and test numerical models. In either case, the results will help the USGS make forecasts of coastal erosion during storms.

Climate-induced changes in phenology in coastal ecosystems- Michelle Staudinger

Shifts in phenology provide one of the strongest indicators of an organism’s adaptive capacity to climate change, yet it is one of the most poorly known consequences of future impacts. This project seeks to improve understanding and develop adaptation strategies of the effects of phenological shifts and trophic mismatches in Atlantic coastal fish, seabird and marine mammal species.
