Science objectives

Mooring recoveries and sampling at 3 Barbados seep sites (El Pilar, Orenoque A, Orenoque B) plus MOCNESS tows and some mapping (multibeam, CHIRP).  We may add sample sites if we are able to undertake an advance SENRY survey in the region (pending request). Our aim would be to add new sites separated by as much as 150-200 km max along a depth gradient and along an isobath.  Use of SENTRY would allow us to undertake precision sampling of known sites, 1 to 1.5 days per station at each of 6 to 8 seep stations.  This is part of the Seep Connectivity Project funded by NSF to investigate historical and contemporary linkages among Barbados, Gulf of Mexico, and Blake Ridge seep species.

We anticipate a two-leg mission, with a small-boat personnel exchange no later than 6 am on 8 June.

Note: We may choose to do Orenoque A and B first; details will depend on whether we get SENTRY time and on teh timing of the personnel exchange.
