|
Summary of Field Work: |
Deployment and operation of the sampler will be tested along a depth gradient at an off-shelf site in the major anoxic OMZ of the Eastern Tropical North Pacific. Briefly, sampling will most likely take place near station 6T (18° 54.0N, 104°54.0 W), a site where the PIs have focused previous sampling efforts (e.g., Ganesh et al. 2018). |
|
Summary of Facility Requirements: |
The sampler will be mounted onto a standard rosette equipped with 10L Niskin bottles and tested for successful firing, injection of preservative, and sample mixing at three depths spanning the anoxic nitrite maximum (~100-130 m), anoxic OMZ core (~300-700 m), and sub-OMZ (~1500 m). |

Optimum Start Date:
|
9/1/2020 |
Dates to Avoid: |
We strongly want to append these days to Mark Altabet's NSF-funded cruise, if possible. Dr. Altabet is aware of this, and has written a letter of support for this proposal. Other than that, we are wanting to work in the optimal weather window. |
