Abstract:
These data present suspended particle size distributions collected by the U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center at three locations in the Sacramento-San Joaquin Delta. Data were collected in Lindsey Slough on April 4 and April 18, 2017, and near the mouth of the Mokelumne River and in Middle River on March 14, 2018 by deploying a Sequoia Scientific Laser In-situ Scattering and Transmissometry instrument (LISST 100x) from a small vessel during the deployment of the hydrographic time series data instruments. At each site, data were collected 1 to 2 times, generally near the water surface, at mid depth, and near the sediment bed. These data were collected as part of a study on the effects of invasive aquatic vegetation on sediment transport in the Sacramento-San Joaquin Delta. Users are advised to check metadata and instrument information carefully for applicable time periods of specific data.
Purpose:
These data were collected for the purpose of estimating particle settling velocity. The survey was conducted as part of a cooperative project, with the USGS California Water Science Center and the California Department of Fish and Wildlife, to provide critical data about the impact of Invasive Aquatic Vegetation (IAV) on fish habitat and the health of marshes to agencies that manage and control IAV in the Delta. These data are intended for science researchers, students, policy makers, and the general public.
Supplemental_Information:
Additional information about the field activities from which these data were derived is available online at: https://cmgds.marine.usgs.gov/fan_info.php?fan=2017-616-FA https://cmgds.marine.usgs.gov/fan_info.php?fan=2017-675-FA https://cmgds.marine.usgs.gov/fan_info.php?fan=2018-609-FA Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in nonproprietary form, as well as in Esri format, this metadata file may include some Esri-specific terminology.

Process_Description:
Files were named with a convention that uses a 16- to 17-digit alpha-numeric code. The first three characters for this dataset are all 'IAV' for the experiment name; the fourth and fifth positions represent the calendar year in which the first data point in the file was taken (18, 2018); the sixth, seventh and eighth (or just sixth and seventh) characters are an alphanumeric code for the site name (for example, MK1). '_L' follows the site name, followed by 7 character start of file time containing the 3-digit day of the year, 2-digit hour and 2-digit minute.
