For all AVIRIS-detected oil slicks (N = 52,100 continuous features) binned into four thickness classes (\u2264 50 \u03bcm but thicker than sheen, 50\u2013200 \u03bcm, 200\u20131000 \u03bcm, and > 1000 \u03bcm), the median lengths, widths, and length\/width ratios of these classes ranged between 22 and 38 m, 7\u201311 m, and 2.5\u20133.3, respectively. The AVIRIS data were further aggregated to 30-m (Landsat resolution) and 300-m (MERIS resolution) spatial bins to determine the fractional oil coverage in each bin. Overall, if 50% fractional pixel coverage were to be required to detect oil with thickness greater than sheen for most oil containing pixels, a 30-m resolution sensor would be needed.<\/p>\n<p><a href=\"http:\/\/www.sciencedirect.com\/science\/article\/pii\/S0025326X15302071\">Ref: Sun, S., C.
