Satellite Data Versus Female Nesting Density
NOAA VIIRS satellite imagery from sampling area (Figure a). Imagery was a composite of moonless & cloudless night skies for the month of May 2014, spatial resolution is 500m/pixel (ca. 180 data points). The coastline was trimmed from the larger imagery and expressed as a line graph by latitude. Units of measurement are W m-2 sr-1 μm-1 . Female nesting density (Figure b) versus average light values within the sampling area of ca 7o km. Nesting data were mean values of 2009-2014 acquired from the data archive maintained at Seaturtle.org.
