Summary of Field Work: |
The project aims to determine the proportion of produced diatom material which can be passed to age-0 walleye pollack prey (large crustacean zooplankton) in the Bering Sea Ecosystem. The areas of interest are fairly broad (north, south shelf) and will sample a grid of stations, potentially aligning with BASIS program. A high-resolution transect will be conducted during transit between south and northern regions. |
|
Summary of Facility Requirements: |
We will need a CTD/rosette, wire for zooplankton net tow, meteorological sensors, ship underway seawater system with sensors, ADCP, satellite internet connection, -80 degree freezer, -20 degree freezer, refrigerators, sufficient deck space for mounting a flow-through incubator (temperature controlled with flowing surface seawater), and a radioisotope van. |
|
Summary of other requirements and comments: |
We can be ancillary users on the research vessel and still have a high probability of successfully meeting our scientific objectives. |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
A van and separate storage area will be required to conduct radioisotope work. We will use carbon-14 (~5-10 mCi stock), silicon-32 (~0.005 mCi stock) and phosphorus-33 (~1.0 mCi stock).
When transiting between our south and north regions of interest, we will conduct a transect and the ship must have the capability to hold position on a particular station for multiple hydrocasts.
