Science Objectives

Map and sample lava flow fields in two specific areas along the east-west trending Galapagos Spreading Center.  Each area is about 40 km x 15 m in size.  Within each area we are specifically interested in the relationship of small seamount strucures to low-lying seafloor adjacent to them.  We will attempt to determine if seamounts are formed during the same or different eruptions from those that produced non-seamount lava flows.  In addition we will map faults and fissures in the areas of interest.

Science Activities

Alivin dives, ~13 in each area.  During nights we will use Sentry, primarily in survey mapping mode in order to obtain high-resolution bathymetry and magnetics data.  We expect to deploy Sentry every night if possible.  In addition we will deploy TowCam on about half the nights, to obtain bottom photographs and wax cores in selected areas.  Possible alternative night-time activities in place of TowCam include rock dredging and wax coring.

Winches

Hydro Winch with .25" hydro wire,
Trawl Winch with 9/16th trawl wire,
Trawl Winch with .681 fiber optic

Winch Notes: We will be using TowCam in fiber-optic mode so we need the necessary winch, wire, rings etc that go with that.  In addition we might do some rock dredging, presumably using the trawl winch.  We might also want to take some wax cores which I assume uses the hydro winch, but I'm not sure about that.
