Summary of Field Work: |
Characterize the microbial community and iron inventory within and above the Benthic Boundary Layer (BBL) along the coast of the Southern California Bight.
This cruise will consist of multiple deployments at 9 selected study sites along the coast of the Southern California Bight. The deployments will involve the use of the ship CTD/rosette, multicorer, and GOFlo bottles to characterize microbial communities and dissolved and total dissolvable iron within the BBL. As well as determining if sediments in this region are a source of macro and micro-nutrients. The work will require one cruise of about 4-5 days of ship time during the rainy season between January and March (earlier is preferred) in order to assess how rain events can affect the parameters of interest in the BBL and how they contrast with data collected during Spring and Summer cruises. |
|
Summary of Facility Requirements: |
We will need a CTD/rosette, a MC-800 Multicorer device and a portable winch for deploying GOFlo bottles. |

Explanation of Science Party Requirements and Technician Requirements |
One technician is requested for supervising deployments early in the cruise. The majority of the science party has extensive experience deploying the equipment to be used. The number of science party members will be able to carry out deployments and sample collection around the clock to maintain a lower need for ship time. |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
In order to sample a station along the coast and maintain a consistent position for proper sample comparison the use of a ship with dynamic position is preferred. Will will be at each station for close to 2 hours and deploy equipment to sample the same location across multiple deployments within that time period.

Explain Major Ancillary Facilities
Requirements and list description
and provider for "other" systems. |
We would like the use of the MC800 corer to sample the sediments, if it is available and feasible. This will help for answering some of our research questions exploring sediments as a source of nutrients along the California coast.
We would also like to request the use of a portable winch for conducting trace metal work. My lab will provide a line and collection bottles but we will need a clean winch to spool our line onto as we will be sampling for trace metals. |
