Summary of Field Work: |
We will conduct a research cruse along the California coast during June or July of 2013, focusing on the region between Monterey Bay and Pt. Conception. We will sample three stations within three similar areas across the continental shelf (9 stations total), the area type will be defined by the nutrient concentrations analyzed in near real time at sea. Ten science days and one transit day will be necessary for this cruise plan. |
|
Summary of Facility Requirements: |
We require a CTD with pressure, temperature, salinity, oxygen, fluorescence, and photosynthetically available radiation (PAR) sensors. A rosette package with ten (minimum) 10-liter Niskin bottles will be necessary for our sampling requirements. The ship must have a working underway system with sensors for temperature, salinity, and fluorescence and the ability to sample underway surface seawater from an uncontaminated line.
Internet access will be required for the PI as we will be receiving daily satellite data from shore to help determine the optimal region of sampling. The capability for color printing and copying will also be necessary.
Deck requirements include a full-sun location for an acrylic incubator within a plywood crate (5 feet x 4 feet footprint), which will be secured to the deck; and also a smaller incubator (50 gallon trash can). The ship must have an operating seawater system, in order to pump surface seawater through the incubators continuously during the cruise to regulate the temperature of the incubated biological samples to that of the surface water.
The lab must be able to accommodate use of radioactive materials, have a working liquid scintillation counter for wipe tests, a fume hood, two sinks, and storage area for hazardous chemicals (mineral acids and fixatives). The lab must have significant bench space to accommodate filtration manifolds, instruments, and workspace. A refrigerator/freezer combination and upright freezer are also necessary for storage of samples while at sea, along with a working Milli-Q (or equivalent) water system. Uninterrupted power supply outlets will be necessary for some electronic equipment. |

Optimum Start Date:
|
6/10/2013 |
Dates to Avoid: |
The success of our research depends on sampling during upwelling season off the California Coast (USA), which is strongest during June and July. Cruise dates outside of these months will not allow us to sample the necessary conditions. |

Explanation of Science Party Requirements and Technician Requirements |
The current science plan involves the earliest hydrocast at 03:00 and the latest at 18:00. Such spacing between hydrocasts would be difficult for one operator provided technician to handle alone. The current science party will consist of the PI, his two laboratory members, and two volunteers. |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
Radioisotope use is essential for the success of the science. Additionally, we need the capability to go to a particular point and hold station for 18 hours.
