U.S. Geological Survey 20170512 1.0 video U.S. Geological Survey Data Release doi:10.5066/F76D5R69 Saint Petersburg, FL U.S. Geological Survey, Coastal and Marine Geology Program https://doi.org/10.5066/F76D5R69 Robert L. Jenkins III P. Soupy Dalyander Allison M. Penko Joseph W. Long 2017 1.0 Open-File Report 2018–1010 Reston, VA U.S. Geological Survey https://doi.org/10.3133/ofr20181010 Weathered oil in the surf-zone after an oil spill may mix with suspended sediments to form sand and oil agglomerates (SOA). Sand and oil agglomerates may form in mats on the scale of tens of meters (m), and may break apart into pieces between 1 and 10 centimeters (cm) in diameter. These more mobile pieces are susceptible to alongshore and cross-shore transport, and lead to beach re-oiling on the time scale of months to years following a spill. The U.S. Geological Survey (USGS) conducted experiments March 10 - 13, 2014, to expand the available data on sand and oil agglomerate motion; test shear stress based incipient motion parameterizations in a controlled, laboratory setting; and directly observe SOA exhumation and burial processes. Artificial sand and oil agglomerates (aSOA) were created and deployed in a small-oscillatory flow tunnel in two sets of experiments, during which, video and velocity data were obtained. The first experiment, which was set up to help researchers investigate incipient motion, used with an immobile, rough bottom (referred to as false-floor) and the second–testing seafloor interactions–utilized with a coarse grain sand bottom (movable sand bed). Detailed information regarding the creation of the aSOA can be found in Dalyander et al. (2015). More information about the USGS laboratory experiment conducted in collaboration with the Naval Research Laboratory can be found in the associated Open File Report (OFR Number Unknown). This dataset includes 42–58 second (s) preview video clips of artificial sand and oil agglomerates acquired with a GoPro camera, during a sea floor interaction (SFI) experiment. The footage was collected during a 2014 USGS small-oscillatory flow tunnel experiment conducted at the Naval Research Laboratory, Stennis Mississippi. The information contained within the videos is needed to capture artificial sand and oil agglomerate incipient motion, and flow velocity at time of incipient motion, under ideal conditions, to test shear stress based incipient motion parameterizations. The information contained within the videos is also needed to capture exhumation and burial processes of artificial sand and oil agglomerates. Observed flow velocities, which provide additional information about aSOA incipient motion, were also collected during each experiment (see 2017_309_DD_SFI_velocity.zip) and are also included in this data release. This dataset (2017_309_DD_SFI_GoPro_preview.zip) contains previews of deployed GoPro video data collected during small-oscillatory flow tunnel laboratory experiments at the Naval Research Laboratory, Stennis Space Center, Stennis Mississippi. To ensure that SPCMSC data management protocols were followed, this survey was retroactively assigned a USGS field activity number (FAN), 2017-309-DD.

The GoPro camera captured HD video, at 30 frames per second (fps). File sizes are generally between 500 MB and 4 GB on disc. All GoPro videos were acquired with the same GoPro camera. The camera was not mounted or secured inside of the oscillatory flow tunnel. Preview video clips are presented for each of the three full length deployed GoPro videos contained in the zip file (2017_309_DD_SFI_GoPro_video.zip) also included in this data release. A formal accuracy assessment of the horizontal positional information in the dataset has not been conducted. In March, 2014, experiments were conducted at NRL’s Sediment Dynamics Laboratory, located in Stennis, MS. Artificial sand-oil agglomerates were deployed in the small-oscillatory flow tunnel with a cross-sectional area of 25 cm by 25 cm, a test bed length of 2-m, and a 35-cm deep sediment well. Oscillating currents (simulating bottom velocities generated by waves) were driven in the tank by a flywheel with variable frequencies (20-90 rpm) and stroke lengths (22, 33, or 44 cm). For all experiments, the oscillatory current had a slight asymmetry resulting in preferential transport downstream (toward the sediment trap) in the tank. Additional information on the characteristics and design of the flow tunnel can be found in Calantoni and others (2013). 20140310 Robert L.

The aSOAs of ranging in diameter from 0.5 cm, 1 cm and 2.5 cm were deployed sitting proud on the sand bed. In addition to the GoPro camera, which was deployed in the trough of one bed ripple, two Canon 7D DSLR cameras captured footage of the aSOAS in 1080p HD video at 30 fps. 20140310 Robert L.
