| Elevation data | RTK GPS | 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. | Li Erikson |
| Conductivity, temperature, depth, salinity, dissolved oxygen, nitrogen, and fluorescence data collected in 2009 in the vicinity of Wainwright, Alaska | tripod | 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. | Li Erikson |

| 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 |
