Anthony H. Knap, Thomas M. Iliffe and James N. Butler. 1980. Has the amount of
tar on the open ocean changed in the past decade? Marine Pollution Bulletin, 11:161-164.
Quantitative surveys of beach tar on Bermuda during
1978-1979 are compared with similar surveys in 1971-1972. A 15%
increase in the mean, while not significantly different from previously
observed levels, is significantly higher than the reported 27% decrease due
to improvements in tanker operations.
