Thanks for the leg work!
Natural foam usually:
appears as light tan or brown in color, but may be white;
smells earthy, fishy or has fresh cut grass odor;
can occur over large areas and accumulate in large amounts, especially on windward shores, in coves and eddies; and
dissipates fairly quickly, except when agitated (as in high wind conditions).
Unnatural foam from human activity usually:
appears white in color;
gives off a fragrant, perfumed or soapy odor; and
usually occurs over small area, localized near source of discharge.
