title: Data from "Burrowing depth mediates the extent of metabolic suppression in a soil-overwintering insect"

description: <em>Metadata are provided in each data sheet. Links to a Shiny app of an interactive simulation, and the underlying R script (on GitHub) are provided below. Refer to manuscript for full details.</em> <br> <strong>Abstract</strong> 1. Conserving energy through winter is important for the fitness of temperate insects. While insects can use buffered microhabitats, metabolic suppression, or decreases in the thermal sensitivity of metabolic rate to override seasonal-scale thermal trends, the relative importance of these strategies for limiting energy use by insects overwintering in soil remains largely underexplored. 2. We used a combined laboratory, field, and simulation approach to investigate the overwintering energetics of the western bean cutworm (<em>Striacosta albicosta</em>), a univoltine lepidopteran pest of dry beans and corn that overwinters underground as a dormant prepupa. 3. We hypothesized that (1) the selection of thermally-buffered microhabitats (<em>i.e.</em> deeper soil sites) reduces energy use in early autumn and late spring, and that (2) changes in the metabolic rate-temperature relationship reduce the impact of elevated temperatures on overwintering energy use. 4. We provide evidence that during the warmest parts of winter, dormant <em>S. albicosta</em> prepupae that had burrowed deep benefited from a cool, stable microclimate, whereas those near the soil surface appeared to rely on deeper metabolic suppression to maintain their energy stores. 5. Although elevated temperatures in the laboratory depleted their energy reserves, these strategies appear sufficient to limit energy drain under natural conditions in the field. 6. We suggest that small-scale variation in the depth of soil refuges may mediate the interaction between the risk of energy drain and changes in the metabolic rate-temperature relationship in soil-overwintering insects. <br> <br>

title: Characterization of seafloor photographs near the mouth of the Elwha River during the first two years of dam removal (2011-2013)

description: We characterized seafloor sediment conditions near the mouth of the Elwha River from underwater photographs taken every four hours from September 2011 to December 2013. A digital camera was affixed to a tripod that was deployed in approximately 10 meters of water (Tripod location from September 2011 to April 2013: 48.15333, -123.55931; tripod location from April 2013 to December 2013: 48.15407, -123.55444). Each photograph was qualitatively characterized as one of six categories: (1) base, or no sediment; (2) low sediment; (3) medium sediment; (4) high sediment; (5) turbid; or (6) kelp. For base conditions, no sediment was present on the seafloor. Low sediment conditions were characterized by a light dusting of sediment; medium sediment conditions were characterized by a layer of sediment that covered all rock surfaces but did not obscure the relief of the seafloor; high sediment conditions were characterized by a layer of sediment that covered all rock surfaces and obscured the relief of the seafloor. During turbid conditions, suspended sediment in the water column obscured the view of the seafloor, and during kelp conditions, blades of kelp covered the camera lens, blocking our view of the seafloor.

title: Oceanographic measurements and hydrodynamic modeling of the mouth of the Columbia River, Oregon and Washington, 2013

description: During May and June of 2013, the U.S. Geological Survey in collaboration with Naval Post-Graduate School, the University of Miami, and Deltares USA, participated in the Office of Naval Research-funded River and Inlets Dynamics (RIVET II) experiment to investigate the hydrodynamics of the mouth of the Columbia River (MCR). The field experiment consisted of the collection of continuous oceanographic data at three moorings, shipboard surveys and Lagrangian drifter deployments to characterize spatial variability in hydrodynamics and water properties, and hydrographic surveys to characterize seafloor morphology in the MCR. These datasets were used to calibrate and validate a hydrodynamic model of the MCR, estuary, and adjacent coast. The majority of field observations were made between Astoria and the North and South Jetties where the Columbia River meets the Pacific Ocean. The RIVET II experiment was conducted between May 9, and June 16, 2013 during the peak discharge measured at Bonneville Dam for the 2013 water year. River discharge at the beginning of the experiment was approximately 10,000 cubic meters per second and decreased to about 6,000 cubic meters per second by the end of the field campaign. Wave heights measured offshore of the MCR during the experiment varied between 0.6 m and 3.9 m and dominant wave periods between 4 s and 20 s. Wind speeds recorded at the land-based weather station ASTO3 varied daily with maximum speeds of up to 12 m/s with variable directions throughout the RIVET II experiment. The data in this release are divided into separate categories including hydrodynamic modeling, Lagrangian drifter data, oceanographic time-series data from moorings, surface-sediment grain-size data, spatial surveys of water column currents and acoustic backscatter. Digital files containing the data from each of these categories generated during the RIVET II experiment and associated metadata are available for download from the child item pages.

title: Digital image mosaics of the nearshore coastal waters of selected areas on the Hawaiian Islands of Hawai'i, Maui, Moloka'i, and O'ahu using aerial photographs and SHOALS airborne lidar bathymetry data

description: The lack of geographic and thematic maps of coral reefs limits our understanding of reefs and our ability to assess change. The U.S. Geological Survey (USGS) has the capability to compile digital image mosaics that are useful for creating detailed map products. Image maps covering the shallow near-shore coastal waters have been produced for several of the main Hawaiian Islands, including Hawaii, Maui, Molokai, and Oahu and are presented in JPEG2000 (.jp2) format. The digital-image mosaics were generated by first scanning historical aerial photographs. At the time, available satellite image resolutions were not acceptable and the aerial photographs used were the best option. The individually scanned digital images were tone-and color-matched and then digitally mosaicked together using spatial matching. Separately, black and white digital orthophoto quads (DOQs) or digital raster graphics (DRGs) of the same areas were merged with shaded-relief images generated from lidar bathymetry data. The resulting black and white images covering both near-shore coastal waters and on-land areas became the geometric masters for the mosaics generated from the aerial photographs. The aerial-photograph mosaics were geometrically corrected to overlay the master data set by using hundreds of image-to-image geometric control points and slaving the mosaic onto the master. The USGS has been investigating the use of remotely sensed image and spatial data to help map and study coral reef environments. Interpretation of these data is corroborated by extensive field mapping and correlation with field measured distribution and density of coral cover and other coral reef cover types. An immediate result of this effort was the generation of very-high spatial resolution georeferenced image maps of critical coral reef habitat areas being studied by the USGS and others.

title: Bathymetry, topography, and sediment grain-size data from the Elwha River delta, Washington, September 2014

description: Two dams on the Elwha River, Washington State, USA trapped over 20 million cubic meters of sediment, reducing downstream sediment fluxes and contributing to erosion of the river's coastal delta. The removal of the Elwha and Glines Canyon dams between 2011 and 2014 induced massive increases in river sediment supply and provided an unprecedented opportunity to examine the response of a delta system to changes in sediment supply. The U.S. Geological Survey (USGS) developed an integrated research program aimed at understanding the ecosystem responses following dam removal. The research program included repeated surveys of beach topography, nearshore bathymetry, and surface sediment grain size to quantify changes in delta morphology and texture following the dam removals. For more information on the USGS role in the Elwha River Restoration Project, please visit http://walrus.wr.usgs.gov/elwha/. This USGS data release presents data collected during surveys of nearshore bathymetry, beach topography, and surface sediment grain size from the Elwha River delta, Washington. Survey operations were conducted between September 5 and September 8, 2014 (USGS Field Activity Number 2014-649-FA) by a team of scientists from the U.S. Geological Survey Pacific Coastal and Marine Science Center (PCMSC), Washington State Department of Ecology (WA DOE), and Washington Sea Grant. Nearshore bathymetry data were collected using two personal watercraft (PWCs), each equipped with single-beam echosounders and survey-grade global navigation satellite system (GNSS) receivers. Topography data were collected on foot with GNSS receivers mounted on backpacks. Positions of the survey platforms were referenced to a GNSS base station placed on a nearby benchmark with known horizontal and vertical coordinates. Depths from the echosounders were computed using sound velocity profiles measured with a conductivity-temperature-depth (CTD) sensor during the survey. A total of 143 km of nearshore bathymetric survey lines and 124 km of topographic survey lines were collected during the 4 days of survey operations. Environmental conditions were favorable, resulting in excellent coverage of the beach and nearshore region. Surface sediment was sampled using a small ponar, or 'grab', sampler on September 5, 2014 from the R/V Frontier at a total of 63 locations in water depths between about 1 and 17 m around the delta. Digital files containing the nearshore bathymetry data, beach topography data, derived DEMs, and grain-size data from this survey are available for download from the child item pages.

title: Data Release for the BOEM-USGS Study of the Regional Importance of Manmade Structures as Rockfish Nurseries in the Santa Barbara Channel

description: Seafloor substrate data available from multiple sources has been modified for the purpose of characterizing the seafloor for the Regional Importance of Manmade Structures as Rockfish Nurseries study. Substrate was classified from multibeam sonar data using a video supervised numerical classification methodology. The overall objective of this study is to begin to integrate region-wide oceanographic, geologic, and biologic data so Bureau of Ocean Energy Management has an ecosystem-level synthesis of the marine environment on which to base management decisions. The initial efforts in applying this synthesis will focus on understanding the regional importance of platform habitat as rockfish nurseries in order to predict consequences of decommissioning oil rigs to essential fish habitat and managed fish species.

title: Data from coastal circulation and water-column properties in the National Park of American Samoa, February-July 2015

description: In 2015, U.S. Geological Survey (USGS) and U.S. National Park Service (NPS) researchers began a collaborative study to determine coastal circulation patterns and water-column properties along north-central Tutuila, in an area focused on NPSAs Tutuila Unit and its coral reef ecosystem. The continuous measurements of waves, currents, tides, and water-column properties (temperature and salinity) from these instrument deployments, coupled with available meteorological measurements of wind and rainfall, provide information on nearshore circulation and the variability in these hydrodynamic properties for NPSAs Tutuila Unit. These data will complement ongoing and future water quality efforts along north-central Tutuila and in NPSA that will provide baseline information to determine impacts resulting from management and (or) climate change. The field experiment included collection of continuous oceanographic data, as well as spatially extensive shipboard surveys and drifter deployments in NPSA from February through July 2015. The goals of the experiment were to understand controls on flow patterns and water-column properties in the NPSA. This data release includes data from acoustic doppler current profilers, conductivity-temperature-depth profilers, satellite-tracked Lagrangian surface-current drifters, and other time-series oceanographic data. A full description of the data and findings of the study are included in a USGS Open File Report: Storlazzi, C.D., Cheriton, O.M., Rosenberger, K.J., Logan, J.B., and Clark, T.B., 2017, Coastal circulation and water-column properties in the National Park of American Samoa, FebruaryJuly 2015: U.S. Geological Survey Open-File Report 20171060, 104 p., https://doi.org/10.3133/ofr20171060.

title: High-resolution multibeam bathymetry and backscatter data collected in 2004 for the northern Channel Islands region, southern California

description: This data release presents data for 5-m resolution multibeam-bathymetry and acoustic-backsccatter data of the northern Channel Islands region, southern California. In 2004 the U.S. Geological Survey, Pacific Coastal and Marine Science Center collected multibeam-bathymetry and acoustic-backscatter data in the northern Channel Islands region, southern California. The region was mapped aboard the R/V Ewing using a Kongsberg Simrad EM-1002 multibeam echosounder. These data were previously published on-line at http://pubs.usgs.gov/of/2005/1153/. In this data release the data have been reprocessed to a finer spatial resolution (5-m versus 15-m) using more modern processing techniques. Due to the large file sizes the entire survey area is separated into two regions; a northern region and a southern region. Four ASCIIRaster files are available. Each compressed file contains an ASCIIRaster file (.asc), a projection files (.prj), and a FGDC metadata files (.xml).
