Summary of Field Work: |
In 2018 we request a 35 day cruise with a suggested beginning and ending ports in San Diego with an intermediate port in Manzanillo. If necessary for ship scheduling, we can use Manzanillo as the start and end ports. We request the Revelle because it will likely be in the region. The Thompson is also a good alternative, as is the Sally Ride. We will use whichever ship is compatible with other scheduling constraints.
The purpose of the cruise will be to investigate the production of nitrous oxide in the low oxygen water column in the Eastern Tropical North Pacific. We will work between 12 degrees N to 20 degrees N and between 102 degrees W and 114 degrees W. We anticipate a cruise track that will cover about 4000 nautical miles including transit. The main work will be along an ~800 nm transect offshore, with three main stations and daily stations in between. We will also sample on part of the return transect to San Diego. At each station, we will collect water samples for dissolved oxygen, nutrient, stable isotope and isotopomer analysis, and for rate measurements using stable isotope tracer incubations. Rate measurements will be concentrated at three stations chosen based on hydrography and water-column oxygen content. These sites will be occupied for several days. Here we will do multiple CTD's to collect water for incubation-amendment experiments. We anticipate there will be ancillary (invited) scientists who will make other measurements, including sediment sampling. |

Summary of Facility Requirements: |
CTD-rosette, multibeam, ADCP, temperature controlled van, freezer room, cold room, multicore |
|
Summary of other requirements and comments: |
This is a revised request because we were told that our first choice, fall of 2017, was not possible within the existing scheduling constraints. So we request spring of 2018 and can use whichever global or ocean class ship is available. Although we would much prefer to end the cruise in San Diego for logistics purposes, we can use Manzanillo if necessary. |

Dates to Avoid: |
Anytime in spring 2018 is fine. If that requires use of another similar ship, rather than the Revelle, that works too. We understand the necessity to work around GEOTRACES |

 Important Info on Foreign Research Clearances
|
|
Are you or any member in your science party bringing in any science equipment items which are regulated for export by the International Traffic in Arms Regulations (ITAR) and/or the Export Administration Regulations (EAR)?
|
No |
If yes, have you applied for the necessary permits through your export control office?
|
No |
| Questions about ITAR/EAR regulations?
|
Comments about foreign clearance requirements or
description of any other special permitting requirements
(e.g., MMPA, ESA, IHA, Marine Sanctuaries, etc.) |
We will make the appropriate permit requests if funded. |

Requested Start Port |
Intermediate Port(s) |
Requested End Port |
|
San Diego, CA, USA |
Manzanillo, Mexico |
San Diego, CA, USA |
Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
We request San Diego for logistical ease and cost in loading and shipping. Manzanillo is a good intermediate port in case we need to switch personnel or have a technical or medical emergency.
If necessary, we can use Manzanillo as the Start and End Port, which would minimize transit days. |
