Summary of Field Work: |
We will be studying various aspects of the mesozooplankton food web, from predator and prey distributions, to diet composition, to stable isotope signatures defining carbon production source during winter (non-upwelling) and summer (upwelling) periods of of Oregon and Northern California.
Biological sampling using Coupled MOCNESS (4 m2 and 1 m2); In Situ Ichthyoplankton Imaging System (ISIIS), and CTD. |
|
Summary of Facility Requirements: |
ISIIS requires a fiber-optic cable and winch for realtime transfer of data. A new fiber-optic winch is available through UNOLS equipment pool (currently maintained by UM RSMAS) -- this winch would be preferred for use on the vessel. We will also require a .322 or larger conducting cable for fishing the coupled MOCNESS (preferably from the stern). |

Repeating Cruise?

Yes |

Description of Repeating cruise requirements: |
Our project goals are to sample during the peak of the winter downwelling conditions (Feb) and during the summer upwelling (June/July). These dates and physical conditions are also tied to the timing of spawning (and larval abundance) of the key study species. |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
Ship choice -- besides local vessel, we require a ship that can work in the coastal seas of wintertime Oregon and which can handle the deployment of both a coupled MOCNESS and ISIIS (including the required winches).
As described above -- our cruise date windows are relatively narrow and are tied to key environmental conditions (winter downwelling, summer upwelling and associated spawning times of target study species.
Total ship days are calculated one the follow -- each of two transects are to be sampled day/night twice during the cruise. Each day/night sampling of a transect will require 24 hours for ISIIS work, and 24 hours for MOCNESS and CTD work (full 48 hours X repeated twice = 96 hr (4 days) X 2 transects = 8 total days sampling plus 24 hour transect from northern transect to southern transect, plus 24 hour return to north at end of cruise. Total science days = 10 d. |

requirements that could affect choice
of ship in scheduling. |
Request new fiber-optic winch in UNOLS equipment pool maintained by WHOI Winch pool. If not available, then will use .681 fiber-optic available through OSU. The value of the new winch and cable is that it is of finer diameter and allows much easier operation of ISIIS.
As to Operator provided MOCNESS -- we are only requesting access to the 1 m2 NETS, preferably 333 um.
As noted above, our MOCNESS will likely require launch/recovery over the stern as the unit is roughly 3.5 m wide and high. Launch/recovery of ISIIS is also over the stern -- but the operations are separated by day.
We will also need CTD with NISKIN Rosette - standard bottles.
