Costa Rica seafloor methane seeps 8 deg 55 N 84 depth 990m.
Included Alvin dives 4586-4591.
The primary goal of the cruise was to recover biological experiments deployed at active and inactive seep areas during Feb./March 2009. We successfully recovered 23/24 experimental units deployed on Mound 12, Costa Rica. One was simply missing on the sea floor. By using a gear elevator each day to maximize sample collection (and reserve ALVIN basket space for experiments) we were able to recover our experiments rapidly. This left us time for exploration of unusual biological communities at Jaco Scar.
Cruise information and original data are available from the NSF R2R data catalog.
Cruise dates changed Feb 2015 to match WHOI ship schedule and R2R.
