Science objectives

The primary objectives of this research are to

(a) characterize the biotic diversity of authigenic, methane-derived carbonates at Hydrate Ridge seeps, from microbes to metazoans, (b) identify the ecosystem-scale interactions among these groups including habitat alteration, colonization, trophic transfer,

(c) assess how proximity to methane seepage influences (a) and (b), define successional dynamics of carbonate ecosystems,

(d) determine the evolutionary affinities of carbonate faunas and (e) refine our understanding of one of the most important paleoceanographic indicators,

C. wuellerstorfi.  Community components to be studied include associated megafauna, attached epifauna, endofauna

(i.e. cryptofauna), and endolithofauna, as well as the biogeochemistry of carbonate environments experienced by these organisms.  

This cruise is the final trip in the project and is focused on recovery of experiments placed at Hydrate Ridge North and South in August 2010.

Science Activities

(1) Experiment Recovery:

(1A) Recover experimental substrates deployed at several locations representing active and inactive seep sites on Hydrate Ridge North and South (500-900 m)

These include rocks, wood, bone, and chips, and slides placed with markers. Each item must be placed in a separate compartment. There are approximately

 Units 50 to recover.

(1B) Recover transplanted carbonate rocks that were moved from active to inactive areas or vice versa in 2010. Each item must be placed in a separate compartment.

There are approximately 16 units to recover.

(1C) Recover snail grazing experiments (rocks in cages with and without snails). Each item must be placed in a separate compartment.

There are approximately 8 units to recover.

(1D) Recover foraminifera microcosms in cages. Each item must be placed in a separate compartment.

There are approximately  20 units to recover.


(2) Sample rocks and biota adjacent to experimental substrates via manipulator, cold boxes, slurps, scoops.

(3) Collect tube cores of bacterial mat, clam bed and other sediments

(4) Generate CTD profiles, collect water from immediately over the seep

(5) Examine OMZ waters (via CTD) and both OMZ and near seep sediments (via multicorer)  as alternative ops if weather fails

(6) Generate multibeam maps for use in ROV dive and elevator placement

Pre-cruise planning meeting: Teleconference

Media personnel on board: Video
an NSF funded Film crew on board a. Mike wants to talk lights and camera, he has one dive, to a site of our mutual choosing. My hope is to share two dives. b. Perhaps a German crew (of one) as well on board
