Cruise Objective:   To test the hypothesis that the continental margin of
                    northwest Africa provides a significant subsurface
                    supply of iron to the open eastern tropical Atlantic,
                    using metal profiles

  WHOI-Provided Equipment: Gravity corer
                           Trace metal block (SSSG) Off of KNORR in Norfolk
  Science Party-Provided   Hytrel coated Vectran
  Equipment:               MITESS (our sampler) 200 lbs (air; neutral in SW)
                           6000 m
                           towed fish (surface); requires boom to be
                           borrowed from Greg Cutter after KNORR cruise,
                           Cutter ok'd
                           Sci-Provided Oxygen Titration rig- JA7/1
  Notes:                   nighttime work anticipated
                           The 11 in-situ pumps each have a shipping crate
                           ~3'x4'x2' need to store.

                           We have arranged with SSSG to use Frank Bahr's
                           SeaSoar SeaMac winch to deploy up to 11
                           battery-operated in-situ pumps using our own
                           plastic-coated non metallic wire (1000m). If
                           possible, we would like to place this winch on
                           the 01 deck and deploy off the hydroboom. We have
                           also asked to use the non metallic metering block
                           that SSSG has.

Other Notes: hazardous material:
             a) We will bring emergency spill kits for the acid and base we
             will be using.
             b) acids and bases will be neutralized for disposal at the end
             of the cruise.
             c) Steve Emerson submitted a cruise questionnaire which stated:
             "See Ed Bolye's cru plan" & Emerson wants 5-7 CTD casts to 1000
             m and (1) to full depth)
             20 ft Container on main deck, port side for storage, load in
