Summary of Field Work: |
(1) Process cruises: R/V Revelle, in summer 2017, 2019, and 2021: Conduct Lagrangian, water-parcel tracking cruises to measure nutrient fluxes and plankton growth, grazing, predation, sinking, and subduction in different mesoscale filaments and eddies associated with cross-shore transport in the California Current System. Multidisciplinary team of biological, chemical, and physical oceanographers.
Each of these 3 cruises needs to be in the summer (preferably early-mid summer, July) of strong mesoscale gradients in the region. Each will be of 32 days duration.
(2) Augmented CalCOFI: R/V Sally Ride, in each of 6 years (2017, 2018, 2019, 2020, 2021, 2022): 3 supplemental days added to 2 CalCOFI cruises per year for additional sampling of microbial, other plankton, and fish populations. Work to be scheduled and coordinated with CalCOFI cruises.
(3) Mooring servicing: R/V Sally Ride, in each of 6 years (2017, 2018, 2019,2020,2021, 2022): 5 days per year for servicing CCE interdisciplinary biogeochemical moorings. |
|
Summary of Facility Requirements: |
(1) Process cruises (R/V Revelle): Seasoar, 1 m2 MOCNESS with 202-µm nets and full sensors, fully configured CTD rosette, isotope vans, trace metal clean van,EK60 or EK80 muli-frequency sonar. Other special equipment to be determined. High speed internet and berthing for minimum of 34 scientists required for each cruise. Science party will supply Trace Metal clean rosette, satellite-tracked drift arrays, Moving Vessel Profiler, and autonomous sampling devices.
(2) Augmented CalCOFI (R/V Sally Ride): Standard over-the-side sampling and laboratory processing equipment and vans. EK60 or EK80 multi-frequency sonar. Oozeki fish trawl (or equivalent) to be provided by science party.
(3) Mooring servicing (R/V Sally Ride): A-frame to accommodate tall mooring buoys, plus suitable winches, navigation, echosounder, CTD rosette. Stable working platform and excellent station keeping ability even in higher wind and sea states. |
|
Summary of other requirements and comments: |
For process cruises on R/V Revelle, continuous, reliable internet service will be required on all ship headings to ensure uninterrupted tracking of over-the-side drift arrays and autonomous vehicles. |

Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
Revelle is needed for berthing capabilities, laboratory space, deck space. Pinkel Doppler sonar would also be useful, Cruise is scheduled for the summer period of strongest mesoscale features in the region. |

Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
San Diego/MARFAC required as port for mob/demob because of extensive sampling and laboratory equipment that must be moved from SIO to research vessel. Also, immediately after the cruise many types of samples need to be rapidly transported to SIO. |
