Cruise Objective:   Mullineaux - The objective of this study is to
                    determine how coral communities form and persist on
                    deep seamounts, in order to understand the dynamics of
                    the component populations and their susceptibility to
                    disturbance. To accomplish this, we need to know where
                    and when communities form, how often they are
                    recolonized, and whether subsequent colonists are
                    supplied by the local populations or immigrate from
                    remote sources.

                    Watling - The recent discovery of deep water corals
                    along the continental shelves and slopes of the United
                    States have ignited strong public interest in their
                    conservation. Many of the corals are long lived and
                    others, especially those that form large bioherms, may
                    be important habitat for a variety of invertebrates and
                    fish, some of the latter of commecial importance.
                    However, at the present time knowledge of the
                    occurances of deep corals in the U. S. is still
                    imperfect so finding areas to target for conservation
                    may involve best guesses or limiting ourselves tot he
                    sites already known.
Science Activities: Mullineaux/Adkins group: Collect deep water corals
                    (scleractinians and gorgonians) and image communities
                    and habitat on Balanus seamount. Deploy colonization
                    surfaces for long-term recruitment study.

                    Watling/Auster group: Collect deep-water corals and
                    image communities and substrate. Also measure deep
                    water temperatures and salinity.

                    Rohwer group - Collect deep water corals and incubate
                    them in situ in order to identify, enumerate and
                    measure metabolic activities and growth rates of
                    associated microbes. Chambers have been developed that
                    allow incubation of coral fragments with various
                    substrates and labels at depth. These samples will then
                    be preserved (at depth) before being brought to the
                    surface for onboard microscopic analysis.
Operations Area:    Balanus seamount, Physalia seamount, and continental
                    slope of Georges Bank
                    39-23'N 65-23'W, ~39-51N 66-55W, and 40-10' to 40-30'N
                    and 68-10' to 67-10'W
                    500 to 4000 m
