Eelgrass Extent 2014 - Central Coast

Eelgrass extent mapped out for selected sites for the Hakai Outer Shores program. Polygons represent eelgrass beds digitized using underwater video. People involved: Luba Reshitnyk (boat operator and data producer), Ondine Pontier (field assistant and video analysis), Midoli Bresch (field assistant),Carolyn Knapper (field assistant), Ben Millard-Martin (field assistant)

Equipment: Splashcam pro, Field computer, Hakai Blue Refer to Video Habitat Mapping protocol.pdf at https://drive.google.com/a/hakai.org/?tab=mo#folders/0Byed_WX-ZNMabWxFTS04MUppWW8

Methods: Georeferenced video data were analyzed by Ondine Pontier with classification of video every 2 seconds for substrate and biological features in a hierarchical classification scheme in an excel spreadsheet. Data were sent to Luba Reshitnyk September 14th 2014. Video data were imported into ArcGIS and polygons were drawn around transect lines where eelgrass was present.
