Abstract:
Following marine oil spills, weathered oil can mix with sediment in the surf zone and settle to the seafloor to form mats up to hundreds of meters long. Wave action fragments these mats into 1- to 10-centimeter (cm) diameter sand and oil agglomerates (SOAs). SOAs can persist for years, becoming buried in or exhumed from the seafloor and/or transported cross-shore and alongshore (Dalyander and others, 2015). These fragments are angular near the source mat and become increasingly rounded as they are transported. To quantify SOA motion, the USGS conducted experiments in November 2016 (field activity number (FAN) 2016-364-DD) and June 2017 (FAN 2017-329-FA) using various size, shape, and density artificial sand and oil agglomerates (aSOAs). Video and velocity data were collected under a range of hydrodynamic forcing scenarios in the Small-Oscillatory Flow Tunnel at the U.S. Naval Research Laboratory (NRL) located in Stennis, Mississippi. Between November 14 and 18, 2016, laboratory studies were conducted on spherical- and patty-shaped particles on a roughened flatbed. Two types of particles were used, one consisting of paraffin wax and sand, while the other was machine-fabricated out of aluminum and coated in sand. Between June 5 and 8, 2017, laboratory studies were conducted on spherical, patty, ellipsoidal, and angular-ellipsoidal particles using paraffin wax and sand, aluminum, and three-dimensional (3D) printed plastic particles.
Purpose:
This dataset presents along-tank flow velocity data collected in November 2016. Along-tank flow velocities were collected by a single Vectrino acoustic Doppler profiler (ADP) located centrally in the small-oscillatory flow tunnel housed at the NRL, Stennis Space Center, Mississippi. The information contained within the comma separated values (CSV) files is needed to capture flow velocity at time of incipient motion. Each CSV file contains a unique name consisting of the experiment run number and trial, which is related to the corresponding video. Additional experimental settings are located in 2016-364-DD_Data_Table.csv and Data_Dictionary.csv.
Supplemental_Information:
This dataset (2016-364-DD_velocity.zip) contains CSV-formatted tabular digital data of flow velocity measurements collected during small-oscillatory flow tunnel laboratory experiments conducted at the NRL, Stennis Space Center, Mississippi. To ensure that St. Petersburg Coastal and Marine Science Center (SPCMSC) data management protocols were followed, this survey was assigned USGS FAN, 2016-364-DD.
