Clams were placed in the field in August 2003 at intertidal (I) and subtidal (S) locations and overwintered subtidally and in the laboratory between October 2003 and May 2004. Sampling took place in the field until October and then in the laboratory until May. Clams were sampled simultaneously in the field and in the laboratory in May to validate agreement between field and laboratory results.
Only fatty acids contributing >1% for at least one treatment combination are reported.
