Allison, supported by a scientific programmer, developed a method for delineating and estimating the length of shoreline associated with offshore kelp beds. Input GIS data included kelp bed polygons, and coastline arcs. This project developed an automated, repeatable, and intuitive approach for associating offshore features (kelp beds) with corresponding sections of shoreline.  Various techniques were tested for projecting a line from regular sampling points along the shore in a way that would be both systematic and representative of a biologist’s intuitive interpretation of ‘offshore’. As an indicator of fisheries habitat value, this technique was used to quantify the percentage of West Coast shoreline that has offshore kelp beds. Project results were presented at the Sixth International Conference on Remote Sensing for Marine and Coastal Environments.
