Table of individual float results and plots are available below.
At right are compilations float plots, e.g., vector displacement, duration chart.
Below compilation figures are float and sound source tables.

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 occured at two levels (700 and 1500 meters) to target two levels of Labrador Sea Water within the DWBC. DLD floats were released approximately every three months, whether directly from a ship, or from a time release mooring. Float mission length was two years, and sound source array was 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 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 included dual release floats which released and began drifting each February 15th.

Individual Float Trajectory and Property Plots
All dates are YYMMMDD; File name convention is fltID_setting#_ballast depth_shelf position*.eps,
e.g., file 'x432s1700_1.eps' is the trajectory plot for float ID 432, which was launched in setting 1, ballasted for 700 meters, and at the inshore-most shelf position (1 being most inshore, 3 being most offshore).
