Coring in Lake Enriquillo, Dominican Republic

This is one of three 4–5 meter long sediment cores recovered from the deepest part of Lago Enriquillo (95 feet water depth). This sediment core most likely represents the late Holocene (~5000 years ago to present), and the scientists will use it to construct precipitation changes in Dominican Republic over that time period.

SPMSC scientist Lauren Toth conducts a photographic survey of the reef

SPMSC scientist Lauren Toth conducts a photographic survey of Porter Patch reef off Key Largo, one of the sites that has been surveyed as part of FWRI’s Coral Reef Ecosystem Monitoring project since 1996. The modern reef surveys will be compared to historic surveys to determine how much structural complexity the reefs of the Florida Keys have lost over the past two decades

Surficial Geology Map of Nantucket and Marthas Vineyard, MA

Map showing the surficial geology from this study and Baldwin and others (2016) with equivalent onshore geology (adapted from Stone and DiGiacomo-Cohen, 2009). The areal extents over which offshore subsurface geologic units crop out at the sea floor were interpreted from seismic-reflection data.
