Abstract
Fourteen techniques for sampling the sea surface microlayer were compared for their collection efficiencies and the degree to which they may preferentially adsorb lipid, protein, and carbohydrate material in the films collected. 3H:14C ratios in doubly labeled surface films generated in the laboratory show that widely disparate results for the chemical nature of in situ films can be obtained depending on the collection device and its compositional material. Stainless steel and Nitex screens exhibit a strong preferential adsorption of lipid material which can only be removed by rinsing in solvent. Filters yield a more representative sample than screens and are better sampling devices when small quantities of film material are needed. Collection efficiencies of slides and prisms are much lower than those of screens or filters.Keywords
