Summary of Field Work: |
The project will require one cruise to the N. Pacific in 2020,. The cruise will be a survey cruise leaving and returning to Seattle (Washington coast) running southwest from the Strait of Juan de Fuca to 35°N 145°W, north to Ocean Station PAPA (50°N 145°W) and then returning to the Strait of Juan de Fuca. We plan for 11 stations with ~12 h at each station. We also are conducting a longer term incubation experiment during the transects that would necessitate collecting larger volumes of seawater with our TM tow-fish.
We will require standard CTD operations and will need to collect trace metal clean water samples by GoFLO bottles on a Kevlar line. We have the line but need a winch and meter block, which has been available in the past. The study will use deck board incubations with flowing seawater. We will need to deploy and tow a TM clean fish at slow speeds (<4 knots) for underway water collections. We have the necessary block for towing but would need to extend it outboard of the ship's wash. |
|
Summary of Facility Requirements: |
We will need a CTD/rosette, radioisotope van, sufficient space for multiple deckboard incubators, a suitable winch and meter block for Kevlar line, and a boom for extending a block and kevlar encased tubing outside the wash of the vessel while underway (TM clean tow fish). |

Optimum Start Date:

6/1/2020 |
Dates to Avoid: |
As with the 2019 cruise, we need to arrived at Ocean Station PAPA shortly following the spring bloom to maximize our ability to measure the natural ligands before photo-oxidation alters the ligand field. |

Description of Repeating cruise requirements: |
none |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
We will need expansive open deck space for the multiple deckboard incubations and flowing seawater for temperature control of the incubations. We are using continuous cultures which will need to be within 40 ft of a weatherproof location for the peristaltic pumps. We will need to use a TM clean towfish (in hand) to collect large volume samples while slowly underway (need the boom provided). We also will need a dedicated winch we can cleanly mount our Kevlar line, and a clean meter block, for deploying GoFlo bottles to a maximum depth of 150 m. |

Short Description of Op Area
for use in schedules: |
OA-Fe Process |
| Description of Op Area: |
We plan to occupy 2 stations, 1 at Ocean Station PAPA and another to be determined by the findings from the transect cruise in the previous year. We plan for 2 experiments which will need ~11 days to complete (set up, running, sampling). The second station likely will be between OS PAPA and the Washington coastal shelf region. |

Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
We need to sample the upwelling region of the Pacific Northwest coast to replicate previous study findings. Departing Seattle provides that logistic. |

Explanation of Science Party Requirements and Technician Requirements |
The Science Party requirements will be very much the same as the year 1 cruise, with the addition of the need to sample with the TM clean towfish (meaning we will need a boom on the vessel as in the past). |

requirements that could affect choice
of ship in scheduling. |
Ultra trace level 59FE and standard level 14C amendments will be used in a subset of incubation experiments, so we will need a UNOLS Rad van equipped with a liquid scintillation counter.
