- Abstract:
-
The U.S. Geological Survey (USGS) conducted field experiments to understand the transport of sediments and associated contaminants in the Hudson Shelf Valley, offshore of New York. The valley is a sink and potential conduit for the movement of sediments and associated contaminants across the shelf. A winter experiment (1999-2000) investigated the role of winter storms in transporting sediments in the valley. A spring experiment (2006) explored transport during the period of spring runoff from the Hudson River. The spring experiment was carried out in cooperation with the Lagrangian Transport and Tracer Experiment (LATTE)- <http://marine.rutgers.edu/po/latte>.

- Purpose:
-
To distribute the oceanographic measurements collected by instruments deployed during this experiment. This information on the physics of flow in submarine canyons will help improve models of circulation and sediment transport and to describe seasonal dynamics. Data collected includes: pressure, current velocity, wave properties, turbidity, water temperature salinity and pressure. The locations, deployment depths, sensor type and parameters measured during the deployment are presented in the tables displayed by the Basic Sampling Interval links for the two seasons on the data server (<https://stellwagen.er.usgs.gov/hudson_svalley.html>).

Public domain data are freely redistributable with proper metadata and source attribution. Please recognize the U.S. Geological Survey as the originator of the dataset. Biological fouling may degrade the transmission measurements after several months of deployment. Organisms grow on the lenses and gradually block light transmission, which results in a gradual upward drift of the beam attenuation coefficient. The attenuation data nor the optical backscatter data have not been corrected for biological fouling and should be interpreted with care.

Bottom-mounted sensors have instrument_height attributes (meters above bottom) were measured prior to deployment. The sensor height above bottom is accurate to within 1 cm, but the depth (representing the initial measurement depth) is only accurate to about 1 meter due to tidal fluctuations and use of nominal water depth. If the sensor acquires data in bins by depth (ADCP, PCADP, AQD), those depths are accurate to a few centimeters relative to each other. Sedimentation or scouring around the platform may change the vertical position over the course of a deployment by as much as 20 cm. In this experiment, the instruments listed at 1 meter depth are mounted on the bottom of the surface buoy hull. In storms, waves can cause changes in depth relative to the changing water surface, so are accurate to 0.5 meters. The design of these moorings maintains the depths of the other (deeper) instruments to an accuracy of +/-1 meter. There are no sensors on the moored instruments to verify the depth, so these depths should be considered nominal.

FIELD PROGRAM: During the winter experiment in 1999-2000, six instrumented tripods (IDs 595, 597, 599, 601, 603 and 604) were deployed in and around the valley with upward looking ADCPs to capture the currents in the whole water column and Benthic Acoustic Stress Sensors (BASS) to quantify near-bottom water flow and sediment concentration. Adjacent moorings at the first 5 sites (IDs 594, 596, 598, 600, and 602) had Seabird Instruments at various depths, providing complementary data on water temperature, salinity, density and attenuation. During the spring experiment in 2006, one tripod (ID 816) was deployed at the same location 595 had occupied in winter 2000 with upward looking ADCPs to capture the currents in the whole water column and BASS to capture near-bottom flow and sediment concentration. A mooring and tripod (IDs 817, 818) were deployed further down the canyon to make the same suite of measurements described above. Each deployment was intended to obtain measurements to describe seasonal dynamics.

DATA PROCESSING: Data processing was conducted using the proprietary software for each instrument, and (or) specialized software developed by the USGS. The proprietary software was often used to download data from the instruments and export the data to ASCII-files. Post-processing of the raw binary or ASCII files was accomplished using USGS software developed in the MATLAB (<http://www.mathworks.com/>) programming language.
Data were first decoded and calibrated from instrument-specific formats and units to the EPIC-standard NetCDF format (<http://www.pmel.noaa.gov/epic/>) and scientific units. Data were carefully checked for instrument malfunctions and then edited. The beginning and end of each data series were truncated to remove data collected out of water. The data were carefully checked at each stage of processing. After final editing, the best basic version of the data file includes all variables recorded at the basic sampling interval with valid metadata. Best basic versions of all data files in NetCDF format are provided.
