Summary of Field Work: |
We plan to conduct depth-discrete midwater trawls using 1m2 and 10m2-MOCNESS systems to quantitatively sample zooplankton and micronekton across epipelagic, mesopelagic, and upper bathypelagic depths. Stations will span the continental shelf, encompassing sharp environmental gradients within the southern California Current Ecosystem. CTD casts and other ancillary operations will also be conducted at each of the stations. EK-80 data will also be continuously collected. |
|
Summary of Facility Requirements: |
10m2 and 1m2 MOCNESS systems are requested, along with appropriate conducting cable, winch, and sensors. Technician assistance is requested for MOCNESS, 24-hour operations -- trawl deployment and recovery and maintenance. Wet lab space is necessary for processing midwater trawling specimens, as well as -80 cold storage and chemical storage for preserved and frozen micronekton samples. We will also need a CTD/Rosette, with environmental sensors, and EK-80 access. |
