Summary of Field Work: |
This work will consist of a series of lagrangian tracking experiments in the NE Pacific, with deployment and recovery of surface drifting sensor packages and continuous water sampling through the ships flow-through system. The first portion of the cruise would be dedicated to retrieval of a profiling float in the vicinity of Station P in the subpolar North Pacific. We will then iteratively deploy and retrieve surface drifting floats at an offshore station, at a transition zone region and in the coastal continental shelf region. This cruise will ideally be scheduled in September 2017. Float and continuous shipboard measurements will be directed to measurement of the diurnal cycle of oxygen and carbon and derivation and validation of primary and community productivity rate measurements. |
|
Summary of Facility Requirements: |
We will need a CTD/rosette, a clean underway seawater system, ADCP,
sufficient deck space for set-up of on deck incubators, and a radioisotope van. |

Description of Repeating cruise requirements: |
|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
We will be deploying a profiling float at Station P (PAPA) in June 2017 via collaboration with Canadian researchers. Given our profiling constraints, we estimate that the float will collect data for 90d, after which it will need to be recovered. Recovery of this float will be the first task of the proposed shiptime. This necessitates a September 2017 cruise. |

Explanation of Science Party Requirements and Technician Requirements |
The science party will consist of at least two members from the White (OSU) and Quay (UW) lab as well as undergraduate and graduate students. We will also invite participants from other labs interested in constraining rates of oceanic PP. Technical support is necessary to run CTD operations and assist with instrument deployment and recovery. |
