Summary of Field Work: |
Summary of Fieldwork: The overarching goal of this project is to determine how contrasting biogeochemical conditions in the North Pacific Ocean affect the depth of net MMHg production and thus the depth at which MMHg enters and is subsequently bioaccumulated in the marine food web.
We propose to collect zooplankton using a 1m2 MOCNESS, micronekton using a 10m2 MOCNESS and particles using large volume in situ pumps at two stations in the equatorial Pacific (5N, 155W, 10N, 155W) during a single cruise ideally in the summertime of 2015. The concentration and isotopic composition of Hg will be analyzed in these samples. |
|
Summary of Facility Requirements: |
Summary of Facility Requirements: We will need s CTD/Rosette, 1m2 and 10m2 MOCNESS trawls, 0.322 or 0.681 EM wire for towing, trace metal clean block and line for GoFLO deployments and sufficient deck space/A frame/winch for deployment and recovery of small drifting array with VERTEX style sediment traps. |
|
Summary of other requirements and comments: |
We request ship time in August or September 2015 in order to coincide with collection made at Station ALOHA in August/September 2014. |

Description of Repeating cruise requirements: |
|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
We suggest the Kilo Moana because its home port is Honolulu, Hawaii and it would simplify logistics (closest to sites, minimize shipping costs and transit days). One of our PIs (Drazen) has a cruise scheduled in Spring 2015. We request 10 days on each of two stations in order to allow sufficient time to collect samples based on our prior experience. Transit time assumes 10 knot and is 8 days using a great circle calculation. One cruise is requested in late summer 2015 to coincide with similar collection made at Station ALOHA August/September 2014. |

Explanation of Science Party Requirements and Technician Requirements |
We request two marine technicians from University of Hawaii in order to allow around the clock operations at sea. We request one technician from Scripps (Meghan K. Donohue) to assist with the 10m2 MOCNESS operations as we have done in the past. |
