Summary of Field Work: |
As a supplement to our MCR-LTER proposal we request one 20-day cruise on a UNOLS Ocean/Intermediate class vessel. This work will be used to help the MCR connect large scale oceanographic and biological properties in the South Central Pacific to patterns observed on the reefs of Moorea. Cruise tasks will include: 1) multi-beam sonar measurements to obtain high resolution bathymetry in the waters around Moorea and Tahiti; 2) CTD/ADCP profiles to obtain hydrography around the islands; 3) water column sampling of: nutrients, POC, DIC, DNA structure, distributions of zooplankton and larval fish to assess connectivity, and a full suite of microbial samples. We will also use coordinated sampling with small boats to obtain a radiative sampling grid around the islands, to link the deep and shallow water measurements. The cruise will enter the territorial waters of French Polynesia.
This project will be a collaboration between A. Alldredge (UCSB), C. Carlson (UCSB), J. Hench (Duke), J. Leichter (Scripps), and L. Washburn (UCSB). |

Summary of Facility Requirements: |
For a successful project we require full use of the ships facilities including: XBT, CTD with Niskin bottle rosette, winch suitable for net tows, ADCPs, EM122 and EM710 multi-beam systems, flow through sea water, compressed air, full complement of bunks available for scientists, radioisotope van with hook-ups, uncontaminated seawater for in laboratory analyses, MET data, and ‘live’ internet (as available) for public outreach. We request use of small boats (RHIBs) to conduct radiative sampling transects between the ship and shallow nearshore waters.
We also request the services of the Hawaii Mapping Research Group (HMRG) staff for seafloor mapping work. Much of the area of interest is in water too shallow for the R/V Kilo Moana to safely conduct mapping, therefore we also request the full use of HMRG’s 25’ survey launch R/V Ahi, including it’s 240-kHz multibeam, POS-MV system, and Seabird CTD (http://www.soest.hawaii.edu/pibhmc/pibhmc_ahi.htm). The R/V Ahi would transit to the field site in Moorea aboard the R/V Kilo Moana. |

Description of Repeating cruise requirements: |
|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
We are requesting the R/V Kilo Moana (or higher Global Class) because of it’s high berth capacity, proximity to the study site, and bathymetry mapping capability (with HMRG staff/equipment). The number of science days assumes embarkation in Papeete, French Polynesia (on Tahiti), and 10 days of dedicated bathymetry/ADCP/hydrographic mapping, plus 10 days to conduct the biological sampling. The mapping time estimate is based on a cruise track comprising of concentric laps around (and between) Moorea and Tahiti between the 50-m to 2000-m isobaths. This assumes 24-hr operations on the R/V Kilo Moana, 510 km per lap at ship speed of 10 km/hr (~ 5 days), plus 5 days total on stations for hydrocast profiling.
In parallel with the R/V Kilo Moana surveys, we plan to use the R/V Ahi to conduct shallow water multibeam bathymetry mapping between the 10-m and 200-m isobaths. For the R/V Ahi, we request 20-days of field operations (assuming 8-hrs/day and 10 km/hr survey speed). This would translate into 1 lap per day around Moorea’s approximately 60-km perimeter. Assuming a 5x water depth swath width, we expect to need about 6 laps around Moorea to obtain sufficient overlap. We also plan to use the R/V Ahi to survey the 12 reef passes on Moorea, and bays and lagoons. Once these primary objectives are met, if weather/time permits we would also survey the nearshore areas of the northwest shore of Tahiti.
The second 10-day leg will sample a grid of stations between Moorea, Tahiti and Tetiaroa for hydrographic and biological parameters. 3 mobilization days are requested: 2 on the front end to set up equipment and 1 to unload equipment and samples. |
