Abstract : Twelve species of algae from the Northeast coast of the United States, three species of planktonic algae grown in the laboratory, a pelatic algae, a recent sediment and a sample of mixed marine plankton were analyzed for normal alkane hydrocarbons over the range C14H30 to C32H66. The results: the benthic algae and mixed plankton exhibit a slight odd carbon predominance; the planktonic algae grown under controlled laboratory conditions had a slight odd carbon predominance; the recent sediment sample from Tarpaulin Cove, Mass., shows a pronounced odd carbon predominance; definite differences in hydrocarbon distribution between classes were found (The red algae, the green algae and the mixed marine plankton show a strong predominance of n-heptadecane. In the brown algae n-pentadecane predominates; the Fucules have a higher ratio of n-pentadecane to n-heptadecane than the Laminariales.); all plant samples show a hydrocarbon minimum in the n-C18H38 to n-C21H44 region and a moderate maximum in the n-C27H56 to n-C30H62 region; pristane was found in several samples but phytane was not detected.
