South Atlantic Bight (SAB) continental shelf off Long Bay (-79W, 32N; -77W, 34 N)
Description

Glider recoveries (Ramses, Pelagia), then battery replacement, reballasting, redeployment (at LB2).   Acrobat surveys, upper slope to outer shelf CTD surveys, station sampling for water samples and primary productivity experiments (deck incubations and 'photosynthetron').  Attempted to survey a subsurface bloom in the mid-shelf (apparently Phaeocystis).   During an Acrobat survey, the tow cable failed over upper slope.  The Acrobat package was located with an acoustic range-finder but was too deep for a grapple attempt.   With the very mild winter, shelf conditions were already post-winter (warm water across outer to mid-shelf) and not favorable for the winter bloom formation.  Given the conditions the cruise was cut short by a few days.

Cruise information and original data are available from the NSF R2R data catalog.
