Summary of Field Work: |
We propose to conduct a research cruise across the eastern portion of the North Pacific Subtropical gyre (NPSG) during the summer productive season (Aug-Sept, 2014.). The proposed cruise will last ~30 days and sample the California current system (~5-7d) and the eastern NPSG along 32°N until ~160°W. At this point the proposed track turns south to 20°N and then eastward to Hawaii and the time series site at Station ALOHA. Planned ports of embarkation and disembarkation are San Diego, CA. and Honolulu, HI, respectively. The cruise will combine water column sampling at regular intervals (2x d-1) with on-deck nutrient addition bioassays . Standard above water underway sensors for irradiance, temperature, wind direction and speed are also requested. |
|
Summary of Facility Requirements: |
We will require water column sampling equipment: CTD rosette with 24x10L niskin bottles. We also request a in-situ fluorometer on the rosette, a ADCP, O2 sensor, and tranmisometer. Sampling depths will not exceed 1500 m.
Additionally, we will have need for a radiation container for the use of both 14C and tritium. Access to underway seawater in labs will also be required.
On deck we will have several incubators that will need to be cooled with surface seawater. Standard lab facilities will be required: milli-Q water, -80°C and -20°C freezer space, bench space for 12-15 scientists, oven, refrigerator or refrigerated room. |
