| Description |
In 2015, scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC) conducted sediment sampling surveys on and around the barrier islands of Dauphin Island and Little Dauphin Island, Mobile County, Alabama (AL) under USGS Field Activity Number (FAN) 2015-322-FA (sub-FAN 15BIM09). The study investigated surficial sediment surrounding Dauphin Island and surrounding environments to inform sediment transport model scenarios of coastal change. This data release provides the average grain-size distribution computed from multiple runs of the 240 samples, each from a unique site, which is a subset of samples report in and methods detailed in in Data Series 1046 (Ellis and others, 2017). Sediments were collected from coastal sub-environments including dunes, beaches, protected bays, and open water. The sampling efforts by the USGS were part of a larger study to assess the current state and future function of Dauphin Island, Alabama and assess what types of restoration efforts are feasible, sustainable, and can be resilient to future storms. The data collected and presented in this data release will be utilized by modelers in an attempt to address these questions using hindcast / nowcast modeling as it relates to baseline condition and storm events. This study was funded by the National Fish and Wildlife Foundation, which is administered by the Gulf Environmental Benefit Fund, following extensive consultation with the Alabama Department of Conservation and Natural Resources. This report supplements the prior Data Series by providing each samples detailed grain distribution used by Ellis and others (2017) to compute traditional grain-size summary statistics. [More]
