Summary of Field Work: |
We will be deploying Carbon Flux Explorers (modified SOLO-2 floats with Optical Sedimentation Recorders). We will also deploy two surface tethered sediment trap arrays and McClane pumps. In addition we will deploy CTD/rosette system with particle sensitive optics. Aim: (1) to Calibrate CFE imagery in terms of POC and PIC fluxes; (2) to investigate observed 20 fold biases in estimates of coastal sedimentation. (3) to relate remotely sensed biomass indicators to subsurface sedimentation. Locations will include Santa Catalina Basin, Santa Cruz Basin (1970 m). a Transect from Santa Cruz Basin 500 km offshore of California. As well at the Hawaiian Ocean Timeseries (HOT). |
|
Summary of Facility Requirements: |
We need shore internet access (without volume restriction) for satellite data access, and Control/Recovery operations for Carbon Flux Explorers. We need a small boat for recovery ops - if necessary. We will launch and recover a surface tethered twin OSR package designed to operate at 250 m. Ancillary data will be colected using optical sensors deployed using a SBE-911 CTD/24 bottle rosette (we may use only 12 10L bottles). Need 60m/min winch lowering/recovery speed and at least 4000 m depth capability. Need precise control of winch speed. CTD should have capability to read digital sensors and be able to power and read as many as 8 sensor channels (including O2 and Fluorescence). ADCP, MET data, Along track T, S, transmissiometer and fluorescence required. McLane pumps use a coated vectran cable and are deployed from the Ships hydroboom - utilizinng a hydrowinch. Not to interfere or require wire swapping with the CTD/Rosette package. |
|
Summary of other requirements and comments: |
We also will bring along as many as 6 UC Berkeley/Santa Cruz undergraduates as part of the science party to help with the workload. |

Explanation of Science Party Requirements and Technician Requirements |
Team size has been appropriate in order to maintain a schedule of frequent CTD casts, Carbon Flux Explorer deployments and Recoveries, in-situ pumping, and Drifting sediment trap deployment/recovery. |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
We launch and deploy autonomous profiling floats, called Carbon Flux Explorers. These are deployed and recovered with the aid of the ship's crane. Normally deployed from the stern and recovered on the starboard side. Fine ship handling required on recovery. We hope to have drone assistance in-order to facilitate float recovery.
