Summary of Field Work: |
Conduct oceanographic sampling in July-August 2015 of upper 100 meters at stations in the subarctic NE Pacific Ocean from near Vacouver Island out to Ocean Station Papa (about 1300 km) for study of DMS biogeochemistry. We will conduct underway monitoring of dissolved gases, DMSP, and DMSO. Shallow CTD casts will be made at sites selected during the cruise to collect water samples for measurement and incubations on board. Samples will be incubated on deck in flow through incubators. Up to 2 drouge deployments of 2-3 day duration will be made during the 16 day cruise. |
|
Summary of Facility Requirements: |
We will need a CTD Rosette equipped with Go-Flo or Niskin sample bottles of 10-20 L size and with fluorometer, beam attenuation and PAR sensors. We will need the underway thermosalinograph and MET system in good operation to interface with our underway sampling equipment. Underway water pumped to labs for automated analyses. We will need light A-frame or small crane for deployment of drogue. We will need deck space for flow through incubators. We will also need a radiation van with scintillation counter. Water purification system on board. Storage for compressed gas cylinders. |

Description of Repeating cruise requirements: |
|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
We need a relatively large ship like the Oceanus to accomodate all the equipment and personnel from at least 3 science groups (Kiene, Dacey, Tortell). We would be open to inviting other other scientists to carry out compatible research, preferably other sea-air interactions. The cruise should take place in 2016 and the ideal month is August so we are there for the period of high DMS concentrations. If timing needs to be shifted, then earlier is better than later as DMS can build up earlier in the summer, but can decline quickly after Sep 1 due to onset of fall. We request 17 days at sea, with 14 science days (3 days in transit). This is necessary to acomplish goals of project for targeting different DMS hot spots identified during the cruise. We should be able to start underway sampling almost immediately but we give ourselves 1.5 days going out and 1.5 days coming in for ramp up and down, respectively. Up to 2 Lagrangian drifts (2-3 days each) may be carried out. |

Line P |
| Description of Op Area: |
We will sample coastal waters off Washington and British Columbia and the established Line P transect monitored by Canadian researchers. The area encompases nutrient rich coastal waters and iron-limited offshore waters. DMS concentrations are exceptionally high in this area. |

Requested Start Port |
Intermediate Port(s) |
Requested End Port |
|
Seattle, WA, USA |
None |
Seattle, WA, USA |
Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
Seattle is the closest major port to the Line P area and would be ideal because the shorter transit time to research area would allow more science days. Newport Oregon would work if necessary, though we might need a little more sea time. There will be no intermediate ports, and ideally we return to same port as departure. The PI, R. Kiene was chief scientist on the Oceanus in 2002. |

Explanation of Science Party Requirements and Technician Requirements |
The science parties will include those of R. Kiene, J. Dacey, and Canadian collaborator, P. Tortell. Additional parties would be welcome, especially those interested in sea-air exchange or trace gas analyses. We will deploy underway sampling instrumentation with mass spectrometer, and a number of chromatograph systems that require significant lab space. Additionally, we will carry out a lot of incubations requiring deck incubators and space in the laboratory for procssing and analysis. The marine techs will be needed to help with hydrographic surveys and CTD deployments and drogue deployments. |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
We would have modest needs for overside deployments. We will deploy CTD rosette with large (10-20L) water sample bottles. We will deploy drifting drogue, but those are relatively light weight. A good seachest (underway water system), preferably clean, is needed.
A variety of chromatographs will be used in the laboratory, and compressed gas cylinders will be needed. Reasonably well exposed space for deck incubators will be needed. A radioisotope van is an absolute requirement. The largest possible. The work will rely extensively on radioisotope tracer experiements. We use mainly 35S (87 day half life; low level beta). A functioning scintillation counter on board is required. The PI has extensive experience with 35S-rad work. We will also use some 3H and 14C in the rad van.
