Experiment Design
The Export Pathways Experiment was designed to examine the pathways of the Deep Western Boundary Current (DWBC) in the Labrador Sea as it meets and passes by the Flemish Cap. Seedings occur at two levels (700 and 1500 meters) to target two levels of Labrador Sea Water within the DWBC. DLD floats were/are released approximately every three months, whether directly from a ship, or from a time release mooring. Float mission length is two years, and sound source array is designed to be heard by floats in the Labrador Sea and around the Grand Banks into the Newfoundland Basin. The first cruise was on the WHOI R/V Oceanus: on this cruise sound source array was moored, CTD stations were taken, and floats deployed. Each subsequent cruise was/will be from the Candian Fisheries vessels Hudson or Teleost, which performs a repeat survey along the Bonavista Line every May, July, and November. The November deployment will include dual release floats
which will release and begin drifting each February 15th.
