Description: This layer shows the distribution of Bull Kelp (Nereocystis leutkeana) in Kachemak Bay in 2002. The kelp map was generated by manual interpretation of low level (1500-5000 ft) oblique color air photos. The photos were obtained during the lowest tides of the month, targeting August and September. Optimal weather conditions were set for visibility greater than 5 miles, surfaces winds less than 10 knots, sea/swell state less than 1 m and sun angle greater than 30 degrees above the horizon. Kelp canopies were delineated on air photo hard copies, scanned at 600 dpi, and rectified to 1 m black and white digital orthophotos (collected by USGS September 9, 1996). The kelp canopy polygons were then traced on-screen.
