Cruise Objective:   GOMTOX: Dynamics of Alexandrium fundyense distributions
                    in the Gulf of Maine: an observational and modeling
                    study of nearshore and offshore shellfish toxicity,
                    vertical toxin flux, and bloom dynamics in a complex
                    shelf sea.

                    Determine the interannual and interdecadal distribution
                    of Alexandrium fundyense (red tide) cysts in the Gulf of
                    Maine and Bay of Fundy...and onto Georges Bank as time
                    permits. This will be the 3rd annual cyst survey onboard
                    the R/V Oceanus. At each station, a Craib Corer will be
                    deployed to sample surficial bottom sediments (top 3cm).
                    Cores will be sectioned and processed on the way to each
                    station.

  Notes:                   Night Work Anticipated
                           Will Bring small, light Craib Corer for coring
                           operations in the CTD area (starboard). Corer
                           will be attached mechanically to the CTD
                           conducting cable without need for electrical
                           connection. This set-up has been successful for 2
                           previous cruises on R/V Oceanus. Deployment and
                           retrieval is similar to CTD/rosette using
                           tuggers--one deployment/station if successful
                           core is obtained.

                           Will bring small Seabird CTD (internally
                           recording)--no need to connect to electrical
                           conducting wire with slip rings. One bottle will
                           be attached on the wire and tripped by messenger
                           during CTD cast--one-two deployments/day. Will
                           use same wire as Corer noted above--5 min
                           changeover necessary.

                           Will use formalin and methanol in the hood area
                           of the WetLab. Spill kit will be provided. Waste
                           formalin will be removed at the WHOI dock at the
                           end of the cruise and placed in the appropriate
                           storage for that chemical

                           Compressed gas cylinders will be brought onboard.
                           Those will be secured in a safe manner along the
                           bulkhead on deck and in the lab while in use.
