Equipment:             Fume hood
WHOI-Provided Science  5-liter Niskin bottles, w/racks
Tools:                 Pinger for wire use
                       Chest freezers (??)
                       Gravity corer
Program-Provided       multicorer (From Duke)
Science Tools:         Internally recording CTD
                       CHIRP sonar
                       Coring van
Shipboard              Standard navigation equip.
Equipment/Nav:         Trawl winch w/ 9/16" wire for multicorer
                       Hydro winch w/1/4" hydrowire for gravity coring
                       Power for coring van
Other Requirements:
Notes:                            1) Coring van should be on fantail level
                                  2) chemicals used: 4% buffered formalin
                                  sol'n
                                  3) Request Hydrowinch speed: pay out at
                                  100 - 125 m/min req'd for gravity coring.
                                  Typical gravity core pull out tensions at
                                  4500 meters - approx 2500 lbs. Weight of
                                  gravity core can be varied to work within
                                  SWL of wire.
                                  4) Niskin bottles - 20 each - 1.2 liter
                                  bottles will do.
                                  NOTE: 5 liter bottles being provided
                                  5) CHIRP sonar to be towed from trawl
                                  wire at 5-8 kts.
                                  Signal cable to be clamped during launch.
                                  6) Direct questions to C. Eben Franks -
