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. Purpose: Data were obtained to provide inputs and validation data for a numerical model, and additionally to provide baseline environmental data previously not available.

Process_Step: Process_Description: Single-beam bathymetry data were collected from a small boat on August 25-29, 2010 using a Humminbird 898 SI Fish Finder with integrated GPS. Accuracy is better than 4 meters (m) horizontal and 25 centimeters (cm) vertical. Data were processed using SonarWiz software and depths were extracted using automated bottom tracking methods. Depth values are meters below the water surface. The 2010 data were not adjusted to a Mean Sea Level datum. Process_Date: 20110927 Process_Step: Process_Description: Single-beam bathymetry data were collected in 2011 from a small boat or dinghy using one of three systems: a Humminbird 898 SI Fish Finder with integrated GPS, an Ohmex Sonarmite BT integrated with a Trimble GeoHX series GPS, or a Garmin Sounder with integrated GPS. For shallow areas within Arey lagoon, a small dinghy with a draft of <0.5 m was equipped with the Ohmex Sonarmite; however, even with this low draft, measurements were not possible in the western part of Arey Lagoon owing to the very shallow water depths. Because the substrate was composed primarily of silt, making it unsafe for walking across, it was not possible to obtain depth measurements in this area. Each system collected single-beam water depth with accuracies better than 4 meters (m) horizontal and 25 centimeters (cm) vertical. Data were processed using SonarWiz software and depths were extracted using automated bottom tracking methods. Garmin Sounder and Ohmex Sonarmite data were processed using their respective proprietary software packages. Depth are referenced in meters to approximate mean sea level (MSL) using three months of water-level measurements obtained with concurrently recording Aquadopp and AWAC instruments.
