NSF-ALPHA Project Main Page

This page contains the results of the MSEAS group for the reanalysis of ocean dynamical fields in the Nantucket and Martha's Vineyard coastal region during the July/August/September 2014 time period. It provides the MSEAS-PE ocean re-analysis simulations as well as the data processed by the MSEAS group for input, initialization, and/or forcing to these simulations. The data is broken down into two categories: synoptic and historical. Synoptic data consists of bathymetric data, atmospheric data from the National Centers for Environmental Prediction (NCEP), ADCP and CTD data for ocean currents, temperature and salinity from Woods Hole Oceanographic Institute's Martha's Vineyard Coastal Observatory (MVCO), current velocity data from WHOI's high-frequency (HF) radar, WHOI drifter tracks, SST images from Johns Hopkins University's Applied Physics Lab (JHU APL) and the Satellite Oceanography Data Lab at the University of Maine, and profiles from the National Marine Fisheries Service (NMFS). Historical data consists of NMFS profile comparisons for a "normal" (that is, not in El Niño conditions) July and September. We thank all NSF-ALPHA ocean observing colleagues for their data as well as the many above-mentioned data providers.

Historical

The July-September 2014 time period does not coincide with an El Niño event (based on the Ocean Niño Index). Hence, here below, we gathered and processed data for normal years, for the months of July and September which are the months during which drifters are at sea. These data are then used as partial inputs for the initialization of our MSEAS-PE simulations.

• NMFS profiles for Normal July Months: year-to-year comparisons
• NMFS profiles for Normal August Months: year-to-year comparisons
• NMFS profiles for Normal September Months: year-to-year comparisons
