title: Eelgrass distributions and bathymetry of the Nisqually River delta, Washington

description: This data release presents eelgrass distributions and bathymetric data from repeated surveys performed on the Nisqually River delta to document interannual changes in eelgrass abundance and coastal morphology following the removal of dikes in 2009 that restored tidal processes to over 300 ha of former freshwater wetlands. Survey operations were conducted by a team of scientists from the U.S. Geological Survey Pacific Coastal and Marine Science Center and Washington State Department of Ecology. Eelgrass distributions and bathymetric data were collected along a series of shore-perpendicular transects spaced primarily at 25-50 m intervals from the R/V George Davidson equipped with a single-beam sonar system and global navigation satellite system (GNSS) receiver (fig. 1). Acoustic backscatter data were analyzed using a custom graphical user interface that implements a signal processing algorithm applied to each sonar sounding that differentiates and extracts the location of the seafloor apart from the presence of vegetation (Stevens and others, 2008). A towed underwater video camera was used identify the presence or absence of eelgrass along a limited number of survey transects to evaluate the classification of the single beam sonar data. This data release currently contains eelgrass distributions and bathymetric data from 3 surveys performed on the Nisqually River delta between 2012 and 2017 and will be updated as data from future surveys become available. Links containing eelgrass distributions derived from acoustic and towed underwater video surveys, bathymetric data, and associated metadata are provided in the child pages listed below. Figure 1.

title: Oceanographic measurements collected in the Stillaguamish River Delta, Port Susan, Washington, USA from March 2014 to July 2015

description: This data release includes time-series and discrete measurements made within two breaches constructed in a former flood-control levee of a restored agricultural area in Port Susan, Washington. An area of approximately 61 ha near the mouth of the Stillaguamish River was reconnected to tidal flow via levee breaches as part of a larger restoration effort that took place in 2012. These observations were collected as part of the USGS Coastal Habitats in Puget Sound Project to characterize sediment fluxes in the restored area. These data help assess the success of the restoration effort from a hydrodynamics and sediment-transport perspective. Included in this release are oceanographic time-series data collected at 15-minute intervals from March 21, 2014 to July 1, 2015, as well as cross-sectional discharge measured within the breaches on March 27, 2014, April 16, 2014, May 18, 2014, and May 29, 2014.

title: Bathymetry data and sediment transport modeling of a submerged nearshore berm at the mouth of the Columbia River, Oregon and Washington, 2020-2021

description: This data release contains gridded bathymetry data from repeated multibeam sonar surveys and input files for a hydrodynamic and sediment transport model application of the mouth of the Columbia River (MCR), Oregon and Washington. The bathymetry data were collected by the U.S. Army Corps of Engineers Portland District Surveys Section between September 9, 2020, and March 10, 2021, to characterize the morphology and dispersal of a nearshore berm composed of 216,000 m3 of sand-sized sediment that was dredged from the MCR navigation channel and placed on the northern flank of the ebb-tidal delta in water depths between 12 and 15 m. Observations of berm morphology were compared with predictions from a three-dimensional hydrodynamic and sediment transport model application developed using the Delft3D modeling system. The sediment transport model was used to predict the amount, timing, and direction of transport of berm sediment outside of the bathymetric survey area. The combination of field measurements and numerical modeling was used to improve understanding and prediction of coastal processes, evaluate the efficiency of the nearshore berm location to enhance the supply of sediment to an eroding coastline north of the inlet, and to inform regional sediment management decisions at the MCR.  These data accompany Stevens and others (2023), the link to which is available in the Related External Resources section, below.

title: Near-bed velocity measurements in Monterey Bay during arrival of the 2010 Chile Tsunami

description: On February 27, 2010, a tsunami originating near Chile arrived in Monterey Bay, California. This data release comprises two hours of pressure and near-bed velocity data spanning the largest tsunami waves. At the time, the U.S. Geological Survey Pacific Coastal and Marine Science Center had a remotely-controlled instrumented platform deployed adjacent to the Santa Cruz Municipal Wharf (mean depth 9 m) for collecting hydrodynamic and sediment transport data. In anticipation of the arrival of the tsunami, sampling was changed to better capture the event. Pressure and near-bed velocity profiles were measured at 1 Hz for 25 minutes every half hour. The velocities are influenced by surface waves, tsunami waves, and tidal currents. The velocity profiles capture the unsteady boundary layer that developed due to the tsunami-induced currents. They are useful for understanding the frictional interaction of the tsunami with the sea floor, as well as sediment transport produced by the tsunami.

title: Aerial imagery and structure-from-motion data products from UAS survey of the intertidal zone at Puget Creek and Dickman Mill Park, Ruston Way, Tacoma, WA, June 2019

description: An unmanned aerial system (UAS) was used to acquire high-resolution imagery of the intertidal zone at Puget Creek and Dickman Mill Park in Tacoma, Washington on June 3, 2019. This imagery was processed using structure-from-motion (SfM) photogrammetric techniques to derive high-resolution digital surface models (DSM), orthomosaic imagery, and topographic point clouds. In order to maximize the extent of the subaerially exposed area, the survey was timed to coincide with a spring low tide occurring at approximately 18:36 Universal Coordinated Time (UTC) (11:36 Pacific Daylight Time (PDT)), with an observed water level of -1.47 meters relative to the NAVD88 vertical datum at the Tacoma NOAA tide station (station ID 9446484). One acquisition flight was conducted at each site: flight F01 covered the Puget Creek area and was conducted between 18:43 and 18:54 UTC (11:43 and 11:54 PDT); flight F02 covered the Dickman Mill Park area and was conducted between 19:24 and 19:37 UTC (12:24 and 12:37 PDT). The flights were conducted using a Department of Interior-owned 3DR Solo quadcopter fitted with a Ricoh GR II digital camera featuring a global shutter. The UAS was flown on pre-programmed autonomous flight lines at an approximate altitude of 50 meters above ground level (AGL), resulting in a nominal ground-sample-distance (GSD) of 1.3 centimeters per pixel. The flight lines were oriented roughly shore-parallel and were spaced to provide approximately 70 percent overlap between images from adjacent lines. The camera was triggered at 1 Hz using a built-in intervalometer. Before each flight, the camera's digital ISO, aperture, and shutter speed were adjusted for ambient light conditions. Twelve temporary ground control points (GCPs) were distributed throughout each survey area to establish survey control. The GCPs consisted of a combination of small square tarps with black-and-white cross patterns and "X" marks placed on the ground using temporary chalk. The GCP positions were measured using post-processed kinematic (PPK) GPS, using corrections from a GPS base station ("TACO") located approximately 5 kilometers from the study area which is operated by the Washington State Reference Network (WSRN). This data release presents five data products derived from these surveys which are available for download: 1) orthomosaic images with a resolution of 1.3 centimeters per pixel, 2) digital surface models (DSM) and hillshade images with a resolution of 2.5 centimeters per pixel, 3) topographic point clouds in LAZ format 4) the geographic positions of the ground control points, and 5) the raw aerial imagery in JPG format.

title: Aerial imagery and structure-from-motion data products from UAS survey of the intertidal zone at Lone Tree Point, Kiket Bay, WA, June 2019

description: An unmanned aerial system (UAS) was used to acquire high-resolution imagery of the intertidal zone at Lone Tree Point, Kiket Bay, Washington on June 5, 2019. This imagery was processed using structure-from-motion (SfM) photogrammetric techniques to derive a high-resolution digital surface model (DSM), orthomosaic imagery, and topographic point clouds. In order to maximize the extent of the subaerially exposed area, the survey was timed to coincide with a spring low tide occurring at approximately 20:19 Universal Coordinated Time (UTC) (13:19 Pacific Daylight Time (PDT)), with a predicted water level of -0.69 meters below mean lower-low water (MLLW) at the Sneeoosh Point NOAA harmonic tide station (station ID 9448576). A total of five flights were conducted for the survey between 19:29 and 20:36 UTC (12:29 and 13:36 PDT). The flights were conducted using a Department of Interior-owned 3DR Solo quadcopter fitted with a Ricoh GR II digital camera featuring a global shutter. The camera was mounted using a fixed mount on the bottom of the UAS and oriented in an approximately nadir orientation. For flights F01, F02, F03, and F04, the UAS was flown on pre-programmed autonomous flight lines at an approximate altitude of 70 meters above ground level (AGL), resulting in a nominal ground-sample-distance (GSD) of 1.8 centimeters per-pixel. The flight lines were oriented roughly shore-parallel and were spaced to provide approximately 70 percent overlap between images from adjacent lines. For flight F05, the UAS was flown manually to acquire imagery over areas not mapped in the previous flights. For all flights, the camera was triggered at 1 Hz using a built-in intervalometer. Before each flight, the camera's digital ISO, aperture, and shutter speed were adjusted for ambient light conditions. Eighteen temporary ground control points (GCPs) were distributed throughout the area to establish survey control. The GCPs consisted of a combination of small square tarps with black-and-white cross patterns and &quot;X&quot; marks placed on the ground using temporary chalk. The GCP positions were measured using post-processed kinematic (PPK) GPS, using corrections from a GPS base station (&quot;SKGT&quot;) located approximately 16 kilometers from the study area operated by the Washington State Reference Network (WSRN). This data release presents five data products derived from these surveys which are available for download: 1) an orthomosaic image with a resolution of 2 centimeters per-pixel, 2) a digital surface model (DSM) and a hillshade image with a resolution of 4 centimeters per-pixel, 3) topographic point clouds in LAZ format, 4) the geographic positions of the ground control points, and 5) the raw aerial imagery in JPG format.
