| Current profiler time-series data collected in 2009 offshore of Wainwright, Alaska | Nortek AWAC | 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. | Li Erikson |
| Water depth time-series data collected in 2009 offshore of Wainwright, Alaska | Nortek AWAC | 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. | Li Erikson |
| Wave time-series data collected in 2009 offshore of Wainwright, Alaska | Nortek AWAC | 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. | Li Erikson |
| Conductivity, temperature and salinity time-series data collected in 2009 in the vicinity of Wainwright, Alaska | microCat | 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. | Li Erikson |
| Grain-size distribution from foreshore and beach samples collected in 2009 in the vicinity of Wainwright, Alaska | hand auger | 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. | Li Erikson |
