Summary of Field Work: |
There are two components to the field work. 1. intense sampling and experimental work at two stations in Chesapeake Bay, each occupied for up to 4 days. 2. Transect sampling en route to/from the stations between Chesapeake Bay and Delaware Bay, including the length of Chesapeake Bay and the Atlantic coastal route between the two bays. The work will characterize the water column chemistry and perform stable isotope incubation experiments, and collect particulate material for later analysis. |
|
Summary of Facility Requirements: |
CTD with O2 sensor, 10 or 20 L Niskins, MilliQ water if possible, George Luther's gradient sampler for high resolution depth sampling, -80oC freezer, underwater clean seawater sampling |
|
Summary of other requirements and comments: |
frig and freezers for both live and dean samples |

Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
Home port of the ship, we know the COVID rules for this port and can manage the transportation safely, it provides a good sampling transect between the port and the stations |

Explanation of Science Party Requirements and Technician Requirements |
We need the tech for support with the CTD and the gradient sampler, and for securing gas tanks. The party size will be determined by COVID guidelines, but six was a safe number previously. |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
CTD is our only sampling method, other than underway water sampling

|
Explain Major Ancillary Facilities
Requirements and list description
and provider for "other" systems. |
We require the cold van for constant temperature incubations. The incubations do NOT involve radio isotopes. We use stable isotopes, which require only standard clean handling procedures. |
