Letter of Concurrence Issued for NASA's EPOCH Mission

There are four operational ocean areas of interest for the NASA EPOCH Mission: (1) East Pacific, (2) Gulf of Mexico, (3) Caribbean, and (4) western Atlantic. NASA's proposed EPOCH Mission will use the same dropsonde technologies as those deployed during the Global Hawk HS3 Mission, thus the same effects previously considered in 2012 are expected to occur for the EPOCH Mission in all ocean basins.
