CTD rosette being deployed
Detailed Description
A CTD-rosette is a commonly used instrument that measures conductivity (that can inform scientists about salinity), temperature, and depth (CTD). As the instrument is lowered into the water--sometimes down to great depths--the cylinders around will open at various depths to collect water samples at discrete locations throughout the water column. This instrument in particular is being deployed from the R/V Pelican to study Climate and Environmental Change in the Gulf of Mexico.

Paleoceanographic Proxy Calibration
A sediment trap time series in the northern Gulf of Mexico is used to better assess the control of environmental variables (e.g., temperature and salinity) on the flux of both microfossils and molecular fossils to the sediments. The information gained from sediment trap studies is used to develop better proxy-based estimates of past oceanographic conditions from analyses of microfossils and...
Climate and Environmental Change in the Gulf of Mexico and Caribbean
This project documents paleoceanographic, climatic, and environmental changes in the Gulf of Mexico and adjacent land areas over the last 10,000 years. The paleoenvironmental data is used to determine rates of change in the past, and to better understand both the natural and anthropogenic factors that contribute to climate variability on inter-annual to millennial timescales.
