Reconstructing millennial-scale hydrologic variability of nearshore environments of south Florida during the Holocene- Lauren Toth

This internship will provide an opportunity to use the USGS’s extensive coral-reef core archive and geochemical laboratory facilities to develop novel paleoclimate and paleoceanographic reconstructions of coral-reef habitats in south Florida. This cutting-edge research will be potentially transformative to our understanding of the millennial-scale evolution of the environments of south Florida...

Natural Drought and Flood Histories from Lacustrine Archives

Previous work performed as part of the USGS Holocene Synthesis project illuminated complex centennial-scale patterns of drought and wetter-than-average conditions across the North American continent interior during the past two millennia, where paleorecord data coverage is sparse.  In order to explain the patterns of naturally-occurring drought, floods, and storms for the past, identified by...

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...

Wetlands in the Quaternary Project

Wetlands accumulate organic-rich sediment or peat stratigraphically, making them great archives of past environmental change. Wetlands also act as hydrologic buffers on the landscape and are important to global biogeochemical cycling. This project uses wetland archives from a range of environments to better understand how vegetation, hydrology, and hydroclimate has changed on decadal to multi-...

November 24, 2017

It may be hard to believe the legend that sailors long-at-sea once considered manatees to be mermaids. The manatee nickname – the “Sea Cow” – which comes from the herbivores’ affinity for grazing on vegetation and their slow, ambling way just makes more sense. But a U.S. Geological Survey video reveals that while they may be cow-like, they also have more than a bit of the magical mermaid to them.

November 8, 2017

Coastal communities count on beaches for recreation and for protection from large waves, but beaches are vulnerable to threats such as erosion by storms and flooding. Whether beaches grow, shrink, or even disappear depends in part on what happens just offshore. How do features like shifting sandbars affect waves, currents, and the movement of sand from the beach to offshore and back?
