The primary purpose of the cruise was to set an array of nine moorings in the vicinity of Great South Channel as part of the U.S. GLOBEC Program Northwest Atlantic Field Studies, Phase 2. The array consisted of surface moorings, sub-surface moorings, and bottom-mounted tripods with upward-looking ADCPs at sites 3, 4 , 5, and 9. A secondary purpose was to describe the hydrographic regime in the vicinity of the moored array. The overall goal is to examine retention (in the form of recirculation around the inner part of Georges Bank) and losses from the southern flank of the Bank into Slope Water or westward into the Middle Atlantic Bight. The positions for the moorings are shown in Figure 1, and the positions for the CTD casts are shown in Figure 2.

The primary purpose of the cruise was to recover an array of nine moorings in the vicinity of Great South Channel as part of the U.S. GLOBEC Program Northwest Atlantic Field Studies, Phase 2. Only a portion of the array was recovered during the cruise due to many and varied reasons. A secondary purpose was to describe the hydrographic regime around the moored array. This was the second major cruise for the experiment. The positions for the moorings, as set, are as shown in Figure 1, and the positions for the CTD casts are shown in Figure 3.
