Summary of Field Work: |
We will investigate physical and biological oceanography along the shelf break of the Beaufort Sea during periods of upwelling and relaxation in summer/early fall.
The fieldwork will consist of 15-20 sampling days in late summer/early fall of 2016 and 2017 along the Beaufort Shelf Break. Both underway and station specific sampling will be conducted. Underway sampling will include bioacoustics, ADCP, a towed profiling vehicle, and bird and mammal observations. Station sampling will be done using CTD and rosette, bongo nets, Tucker trawl, and a midwater fish trawl net. Four year-long moorings will be deployed in 2016 and recovered in 2017. A 25 day cruise is requested with time including transit to/from Nome AK and the Beaufort Shelf (2-3 days each way). |

Summary of Facility Requirements: |
CTD and Rosette

Wire for deploying midwater fish net (0.322 or larger)
A-frame for deploying and recovering moorings.
ADCP
EK60
Underway water and met sensors
Reliable Internet / email access for communicating with North Slope communities |
