Abstract

Dataset consists of burst data collected as part of a tripod deployment. The tripod included the following instruments: Sequoia LISST, RDI 1200 kHz ADCP.

Description

Tripods were deployed for a prolonged amount of time to monitor suspended sediment fluxes as well as conductivity and temperature. Because the tripods were deployed for longer periods of time, biofouling did occur. To combat biofouling, the ADCP was treated with Interlux Trilux 33 antifouling paint, including a thin coat of over the acoustic sensors. This thin layer of paint had a negligible effect on the acoustic data collected by the ADCP. Optical sensors included on the tripod did not have any anti-fouling paint on the sensors (which means their reliability timeframe may be shorter than acoustic sensors), and were secured to the tripod using copper supports. The tripod structure itself was painted with Interlux MicronCSC anti-fouling paint and all instrument bodies were wrapped in cellophane and electrical tape for easy removal of biofouling. It should be noted that data occurring closer to the start date of the deployment is more reliable than data collected later in the deployment. Any excessive biofouling of the tripod should be listed in the logbook during retrieval.

List of files:

• ADCP –This folder includes raw data from each deployment. If data has been processed, the MATLAB m-files for processing are also included.

• LISST – This folder includes all raw data from the tripod deployment. If the data have been processed, MATLAB m-files for processing are also included.

• Logbook – Hand-written field notes and instrument setup documents. This file also contains the deployment log of locations and samples taken during the cruise. All field notes and complications/observations are included here.
