Abstract

Dataset consists of profile and water column burst data and bottom burst data collected as part of a longitudinal cruise along the river in support of an Acoustic Doppler Velocimeter (ADV) tripod deployed in nearby location.

Description

During each station in the cruise, a profile or bottom time series was collected with a suite of instrumentation including: an EXO2 CTD, a Sequoia LISST 100X, TRIOS radiometer, a LI-COR light sensor, a Sontek ADVOcean, and a Nortek Vector ADV. A PICS floc camera system was used to collect three to four 30-sec video sequences of settling particles in water that was collected at the beginning of each burst in its sample column All instruments were attached to a profiler frame which was lowered into the water from a winch, except for the ADCP which was bow-mounted for all deployments. The raw data of profile stations are processed to provide a smooth profile of data throughout the water column and a series of between 2 to 5 minute bursts from various heights in the water column. Bottom bursts are time series collected when the profiler was resting on the seafloor. Total Suspended Solids (and fixed solids) were sampled from depth to calibrate the acoustic backscatter, as well as CDOM water samples. All times are Eastern Standard Time (EST).

List of files:

• ADCP –This folder includes raw data from each deployment. ADCP was bow mounted for all samples. If data has been processed, the MATLAB m-files for processing are also included. If this folder is absent in the data set, this parameter was not collected.

• ADV – This folder includes all raw data from each deployment. If data has been processed, the MATLAB m-files for processing are also included. If this folder is absent in the data set, this parameter was not collected.

• Averaged Data – An Excel spreadsheet that contains burst averaged data and statistics form the water column and bottom bursts.

• CDOM – This folder includes the raw data file for CDOM measurements. If this folder is absent in the data set, this parameter was not collected.

• Consecutive Station Log – An Excel spreadsheet of the metadata associated with each station in the survey.

• CTD – This folder includes all raw CTD data from each deployment. If data has been processed, the MATLAB m-files for processing are also included. If this folder is absent in the data set, this parameter was not collected.

• Li-COR – This folder includes raw Li-COR data from each of the three sensors, handwritten field measurements, and an excel spreadsheet where raw data were analyzed. If this folder is absent in the data set, this parameter was not collected.

• LISST – This folder includes all raw data from each deployment. If data has been processed, the MATLAB m-files for processing are also included. If this folder is absent in the data set, this parameter was not collected.

• 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.

• PICS – This file includes raw (Sequences folder) and processed PICS data along with MATLAB m-files for processing. If this folder is absent in the data set, this parameter was not collected.

• TRIOS - This folder includes all raw radiometer data from each deployment as well as the deployment log. If this folder is absent in the data set, this parameter was not collected.

• TSS – Includes data for total suspended solids, fixed solids and volatile solids from water samples collected during each deployment. If this folder is absent in the data set, this parameter was not collected.
