| Beach profile data collected in 2010 and 2011 in the vicinity of Arey Lagoon and Barter Island, Alaska | Ashtech Z-Xtreme GPS | Beach elevation profiles were measured along 29 shore-normal transects on and around Arey and Barter Islands, Alaska in August 2010 and July 2011. Profile data are available in a single comma-delimited file and a zip file including multiple .jpg images that show a visual representation of the individual profiles. | Li Erikson |
| Single-beam bathymetry data collected in 2010 and 2011 in the vicinity of Arey Lagoon and Barter Islands, Alaska | Humminbird | Single-beam bathymetry data were collected in 2010 and 2011 in the nearshore waters around Barter Island, Arey Island, and within Arey Lagoon, Alaska. Measurements were made from a small boat or dinghy using one of three systems: a Humminbird 898 SI Fish Finder with integrated GPS (2010 and 2011), an Ohmex Sonarmite BT integrated with a Trimble GeoHX series GPS (2011), or a Garmin Sounder with integrated GPS (2011). Each system collected single-beam water depth with accuracies better than 4 meters (m) horizontal and 25 centimeters (cm) vertical. | Li Erikson |
