Research Objectives: The modeling component of the Long Term Ecological Research (LTER) project focuses on temperature and salinity profiles of the water column at each standard station in the study areas. The models will also include weather and navigational data such as wind speed and direction, air temperature and humidity at east station site, as well as latitude and longitude data. Data from shipboard ADCP is also used for interpretation and checking of geostrophic calculations.

Field Season Overview:
Fieldwork for this LTER component occurs aboard the RV Laurence M. Gould. With assistance from shipboard technicians, project team members will deploy SBE 911+ dual-sensor equipped CTD (conductivity, temperature, depth probe) XBTs (expendable bathythermographs). They will use the onboard Autosal and Portasal to determine salinity of water samples. The vesselís continuously-operating data acquisition system will capture meteorological and navigational data.
