Proxy data such as tree rings, ice cores, and microorganisms are collected and analyzed by scientists to unlock past climate records stretching back thousands to millions of years ago.  This video podcast examines how scientists can decipher past climate from such records by focusing on a proxy calibration study in the Gulf of Mexico.  Microfossils recover

This video podcast highlights 50 years of photographic documentation of coral reefs in the Florida Keys.  The photographs show 5 decades of changes that have taken place in both the size and the types of corals that were present at several coral reef sites from the early 1960s to today.  The images capture events such as the appearance of coral disease and

This video podcast looks at the science behind understanding coastal vulnerability and hazards posed by extreme storms.  It documents how USGS scientists study the response of coastal environments to the extreme winds, waves, and currents brought by such storms.

The Submersible Habitat for Analyzing Reef Quality (SHARQ) is a new tool scientists use to understand and map metabolic characteristics associated with marine communities living on the sea floor. This podcast gives a closer look at how scientists use SHARQ to analyze important habitats like coral reefs.

This documentary presents how recent changes in the composition and quantities of African dust transported to the Caribbean and the Americas might provide clues to why Caribbean coral reef ecosystems are deteriorating and human health may be impacted.

In this audio slideshow scientists cruise through tidal creeks, sample mangrove sites, pull sediment cores, and avoid swarms of mosquitoes while conducting studies and monitoring the largest subtropical wilderness in the United States, the Everglades.
