(a) Total beach tar accumulation for the Coal Oil Point study area. (b) Study area tar accumulation versus Julian day with 28-day smoothing with 75% overlap (7/28) and 7-day smoothing with 50% overlap (3.5/7), respectively. Low data density in late December-January reflects poor student availability. (c) Beach tar accumulation versus wind speed for individual and monthly averaged surveys.
