Summary of Field Work: |
This proposal will leverage the BATS sampling program, and enhance its observations by deploying multiple gliders over a 20-month period to better constrain and characterize nutrient inputs to the euphotic zone in order to resolve the longstanding conundrum of high net community production in the summer when nutrient inputs are at an annual minimum. The gliders will include sensors for determining water column microstructure, nitrate concentrations, chlorophyll fluorescence and particle backscatter. These sensors will allow for both the quantification of diapycnal nitrate fluxes and the associated biological response. |
|
Summary of Facility Requirements: |
Facilities needed are ship days to support the extra CTD sampling and glider deployment from BATS cruises. Other needs have already been captured in the BATS ship time request. |

Description of Repeating cruise requirements: |
We request a total of 9 science days to be spreadout as follows. 1 science day on the January or February BATS cruise, and then one day on monthly BATS cruises from March to October 2020. |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
This request is to support the additional CTD work and glider deployment/recovery which can not be comfortable covered in the existing BATS monthly cruise plan. |

Explanation of Science Party Requirements and Technician Requirements |
On each cruise we envision up to 4 additional people for sampling efforts, glider recovery/deployment. These activities are added on to the BATS program. We will not need any additional operator provided technicians beyond what is already on the ship for BATS cruises. |
