This portion of the USGS data release presents eelgrass distributions derived from towed underwater video surveys of the Nisqually River delta, Washington in 2014 (USGS Field Activity Number D-01-14-PS). Eelgrass data were collected from the R/V George Davidson equipped with a towed underwater video system and global navigation satellite system (GNSS) receiver. The underwater video system consisted of a Splashcam standard definition video camera connected to a Sony GV-D1000 video monitor and tape recorder. Positioning of the survey vessel was determined at 0.5 Hz intervals using a Garmin 76c GNSS receiver. The positioning data from the GNSS were encoded onto the audio track of the digital video recording using Red...
In September 2013 the Springs Stewardship Institute received funding from the BOR to map springs and springs-dependent species in the DLCC. Since then we have configured our server, migrated our geodatabase to an ArcSDE, and published several WMS and WFS to our domain at https://arcgis.springsdata.org/arcgis/rest/services . This includes a WMS of springs in the DLCC that we have also made available through ArcGIS Online at http://bit.ly/1k6zo7p . We have also migrated our non-spatial survey data to an online application at http://springsdata.org/index.php . This is a user-friendly interface for a MySQL database that includes georeferencing, geomorphology, flow, flora, fauna, water quality, and condition assessment...

This portion of the USGS data release presents eelgrass distributions derived from towed underwater video surveys of the Nisqually River delta, Washington in 2017 (USGS Field Activity Number 2017-614-FA). Eelgrass data were collected from the R/V George Davidson equipped with a towed underwater video system and global navigation satellite system (GNSS) receiver. The underwater video system consisted of a Splashcam standard definition video camera connected to a Sony GV-D1000 video monitor and tape recorder. Positioning of the survey vessel was determined at 1 Hz intervals using a Trimble R7 GNSS receiver and Trimble Zephyr Model 2 antenna. The positioning data from the GNSS were encoded onto the audio track of the...
