This three year survey effort is collecting information using ultra-high resolution digital imagery on the presence of marine mammals, turtles, birds, cartilaginous fish, other taxa, and boats and other structures. For this project, data analyses methods that integrate data from collaborators and facilitate remote access for data processing have been developed. This provides efficient data flow, traceable QA/QC, and provides quality data outputs in a timely manner.Year 2 Survey Dates (mm/dd/yyyy):Survey5_Summer 2017: 8/6/2017, 8/9/2017, 8/11/2017, 8/14/2017, 8/16/2017, 8/17/2017, 8/20/2017, 8/21/2017Survey6_Fall 2017: 11/9/2017, 11/11/2017, 11/12/2017, 11/17/2017, 11/18/2017, 11/20/2017, 11/23/2017, 11/26/2017, 11/27/2017Survey7_Winter 2017-18: 2/18/2018, 2/19/2018, 2/24/2018, 2/27/2018, 2/28/2018, 3/1/2018Survey8_Spring 2018: 4/21/2018, 4/22/2018, 4/23/2018, 4/24/2018, 4/26/2018



Supplemental information

Transect area is calculated based on the planned aircraft altitude and assumed to be a consistent value. Actual coverage of the area may vary due to fluctuations in the aircraft altitude during the survey. This may result in target observation points being displayed outside the transect area.

Tracklines are viewable online as a static layer.
