Operations Area: Pacific margin of Costa Rica

Lat/Lon: 9° 0.0′ N / 84° 30.0′ W

Science objectives

Full 3-dimensional ocenographic characterization of 5-7 high-flux seep sites on the Costa Rica Pacific margin, with additional sampling of mobile fauna, chemosynthetic communities, infaunal macrofauna and microbial communities. Potentially a few additional dives to offshore seamounts and unexplored seep sites along the margin.

Science Activities

Activities include Sentry and wire flyer characterization of the water column, CTD niskin rosette sampling, geochemistry from push cores, niskin samples on Alvin, mobile fauna collections, community collections using the custom Bushmaster and mussel pots, and carbonate transplants. We will need the elevator to accomplish all of our sampling objectives, particularly early on in the cruise when we are recovering and redeploying carbonate rock transplants.

Pre-cruise planning meeting: Teleconference

It would be great for everyone to participate in one meeting, although the only essential co-PI for the planning meeting would be Chris Roman since he is bringing over-the-side gear.
