Summary of Field Work: |
The purpose of the cruise is to study a phytoplankton bloom that regularly occurs on the Patagonian Shelf at a specific time of year. The period between 25 November to the end of December is optimal for coccolithophore blooms based on remote sensing evidence. The R/V Revelle cruise is currently scheduled from30 Nov (Motevideo, UR) to 29 December (Punta Arenas, Chile). The schedule includes 27 science days, 3 transit days for a total of 30d. |
|
Summary of Facility Requirements: |
1) We will have deck incubators with flowing surface seawater for keeping seawater samples (up to 20L) at ambient surface temperature under ambient light.
2) we will be doing isotope work with 14C thus will require a rad van (and presumably a isotope waste storage van). The 14C work that will be performed will use a technique identical to that performed on two R/V Revelle NSF Biocomplexity cruises to the Equatorial Pacific (EB04- Dec. '04; EB05- Sept. '05)
3) We will carry several tanks of CO2 for on-deck experiments to adjust seawater pH.
4) A radiometer system will be mounted on the bow of the ship for ocean irradiance measurements
5) The ship's underway system will be used for continuous sampling during ship surveys
6) A darkroom will be needed for microscopy
7) We will require a CTD with 12 x 30L bottles (silicon O-rings), also equipped with a) SBE 43 dissolved oxygen sensor, WetLabs transmissometer with 25cm path length, Seapoint Chlorophyll fluorometer, Altimeter, Benthos/DataSonics, 1-99.9 meters
8) If possible, we'd like to have nutrients run on board (Nitrate, nitrite, phosphate, silica and ammonium) pending availability of resources.
9) A trace-metal clean rosette will be brought for iron work, and will require non-conducting Kevlar cable (it is tripped remotely) wound on a separate winch.. |
|
Summary of other requirements and comments: |
Half-way through the cruise, we may be deploying a Slocum Glider at the Shelf break, to repeatedly sample across the bloom. This deployment is still to be confirmed but has been included in the Foreign Vessel request form. The deployment would require a zodiac or similar small vessel in order to facilitate an easy deployment and recovery, without breaking the AUV's wings. |

Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
The period between late November to the end of December is optimal for coccolithophore blooms based
on remote sensing evidence. A 2008 cruise is preferred. |

We will have deck incubators for keeping 20L seawater samples at ambient surface temperature.
14C-bicarbonate will be used as a tracer to measure photosynthesis and calcification using the 14C diffusion technique. This technique is identical to that used on the R/V Revelle in the NSF Biocomplexity Cruises (Dave Nelson- chi sci; EB04 Dec 2004; EB05 Sept 2005), as approved by the Scripps Isotope committee.
As of this writing, the total number of vans on the ship would be three (rad van, waste storage van, and a flow cytometer van of Dr. Michael Sieracki (BLOS)
We will carry several tanks of CO2 for on-deck experiments to adjust seawater pH. A radiometer system will be mounted on the bow of the ship for ocean irradiance measurements. The ship's underway system will be used for
continuous sampling during ship surveys. A darkroom would be needed for microscopy.

Provided our Webb Slocum glider is ready for deployment, we may set the AUV to do continuous cross-shelf transects, about half-way through the cruise then retrieve it prior to heading into Punta Arenas. We would bring all required equipment for its deployment. The only need of the ship is to use its zodiac for deployment and recovery (much preferred for safe handling of the 52kg fish). This was included in the foreign vessel clearance request form already subitted. |
