Summary

This dataset consists of hydrographic, geomorphic, and sediment field measurements obtained during the ice-free summer of 2009 in the vicinity of Wainwright, Alaska. Time-series data were collected with a bottom-mounted instrument package and consist of wave statistics, vertical water flow velocity profiles, water temperatures, conductivity, and salinity concentrations. Data collected at distinct time-points consist of bathymetry, salinity, water temperatures, dissolved oxygen concentrations, fluorescence, nitrogen, beach and foreshore elevations, and grain size distributions of foreshore, beach, and bluff sediment.

Environmental Data

  • Conductivity, temperature and salinity time-series data collected in 2009 in the vicinity of Wainwright, Alaska

    Measurements of conductivity and temperature were collected with a high-accuracy conductivity and temperature recorder (Seabird SBE37 microcat) in approximately 10 m water depth at a single location fronting the village of Wainwright, Alaska, from 24 August to 1 October 2009. The instrument was mounted on the frame approximately 0.50 m off the bottom of the seafloor. Salinity was calculated from conductivity measurements.

  • Conductivity, temperature, depth, salinity, dissolved oxygen, nitrogen, and fluorescence data collected in 2009 in the vicinity of Wainwright, Alaska

    Measurements of conductivity, temperature, and depth (CTD), in addition to dissolved oxygen, nitrogen, and fluorescence, were collected in the Wainwright Inlet, the mouth of the Kuk River, and in the nearshore region off Wainwright, Alaska, in August 2009 with a Seabird SBE 19. Post-survey calculations of salinity were made from the conductivity measurements.

  • Current profiler time-series data collected in 2009 offshore of Wainwright, Alaska

    A time-series of binned current-velocities and recorded ping amplitudes were collected offshore Wainwright, Alaska, from August 24 to October 02, 2009 (UTC). Measurements were collected using a 1 MHz NortekTM AWAC acoustic Doppler current profiler mounted on a frame in approximately 10 m of water. The profiler was mounted on the frame 0.55 m off the bottom of the seafloor, and collected data in 8 vertical bins, centered at 1.95(bin1), 2.95, 3.95, 4.95, 5.95, 6.95, 7.95, and 8.95(bin8) meters above the seabed, measuring over 8.53-minute bursts at 2 Hz. These data are available in a single csv file.

  • Water depth time-series data collected in 2009 offshore of Wainwright, Alaska

    A time-series of varying water depths were collected offshore of Wainwright, Alaska, from August 23 to October 02, 2009 (UTC). Measurements were collected with a built-in pressure transducer from a 1 MHz NortekTM AWAC acoustic Doppler current profiler mounted on a frame in approximately 10 m of water. The instrument was mounted to the frame at 0.55 m off the bottom of the seafloor. Reported depth values include the 0.55 m offset, and thus are depths relative to the seabed. These data are available in a single csv file.

  • Grain-size data from samples collected in 2009 at three bluff locations in the vicinity of Wainwright, Alaska

    Grain-size data, including grain size, cumulative frequency, and median, was determined from samples collected at three bluff locations in the vicinity of Wainwright, Alaska. The different locations (termed W1, W2, and W3) represent three different slope-failure modes. Sediment grab samples for most bluff locations were collected in August 2009, while sediment samples from the bluff at site W3 and multiple foreshore locations were collected in September and October of 2009. Two of the grab samples were sieved and analyzed for grain size distributions (7 classes ranging from 0.06 to 0.72 mm). The grain size distribution of the remaining samples was determined from referenced photographs of collected samples taken in the lab following the method of Barnard and others (2007) using two-dimensional spectral decomposition of sediment images (Buscombe and others, 2010). Results of sieved samples were used to verify mean grain-size values obtained with the image processing algorithm. Data are available in a single csv file.

  • Grain-size distribution from foreshore and beach samples collected in 2009 in the vicinity of Wainwright, Alaska

    Sediment grab samples were collected at 158 locations on the foreshore and beach in the vicinity of Wainwright, Alaska, in October of 2009. Two of the grab samples were sieved and analyzed for grain size distributions. The grain-size distribution of the remaining samples was determined from referenced photographs of collected samples taken in the lab following the method of Barnard and others (2007) using two-dimensional spectral decomposition of sediment images (Buscombe and others, 2010). Results of sieved samples were used to verify mean grain size values obtained with the image processing algorithm. Data are available in a single csv file.

  • Wave time-series data collected in 2009 offshore of Wainwright, Alaska

    Time series wave data were collected offshore of Wainwright, Alaska, from August 24 to October 02, 2009 (UTC). Measurements were collected using a 1 MHz NortekTM AWAC acoustic Doppler current profiler mounted on a frame in approximately 10 m of water. The instrument was mounted to the frame at 0.55 m off the bottom of the seafloor, and collected data in 8.53-minute bursts at 2 Hz. Significant wave heights (Hs), maximum significant wave heights (Hmax), peak and mean wave periods (Tp and Tm, respectively), and peak and mean wave directions (Dp and Dm respectively) are available in a csv file. Spectral wave data are available as a NetCDF file.

Location-Elevation Data

  • Elevation data collected in 2009 on the beach and foreshore in the vicinity of Wainwright, Alaska

    Beach and foreshore elevation data were collected in the vicinity of Wainwright, Alaska. The area from the mouth of the Kuk River to about 8 km to the northeast was measured in August 2009. The area from the mouth of the Kuk River to about 5 km to the northeast was measured in October 2009. The elevation data were collected with Real-Time Kinematic (RTK) Global Positioning System (GPS) systems mounted on all-terrain vehicles. The GPS sampling rate was 1 Hz with vehicle speeds maintained at less than 15 km/hour, resulting in a sample point resolution of 3-5 m. Data are available in a single csv file.

Sonar Data

  • Single-beam bathymetry data collected in 2009 in the vicinity of Wainwright, Alaska

    Bathymetry data were collected in the Wainwright Inlet, the mouth of the Kuk River, and in the nearshore region off Wainwright, Alaska, in August of 2009. Bathymetry was measured with a single-beam echo-sounder (10 Hz 144 ODOM Echotrac CV-100) mounted on the stern of a small vessel and synchronized to a 145 Real-Time Kinematic (RTK) Global Positioning Systems (GPS). The depth is measured relative to approximate Mean Sea Level (see attribute accuracy report in this file for further details on the MSL), and depth values are meters below the water surface. The GPS sampling rate was 1 Hz with vehicle speeds maintained at less than 15 km/hour, resulting in a sample point resolution of 3-5 meters. Data are available in a single csv file.
