Examples of mass spectra of
n
-hexane/dichloromethane (F1) extractable
surfactants isolated by foam tower stripping from a bulk surface seawater sample
(upper), an unslicked microlayer (centre), and a heavily slicked microlayer
(lower). The spectra show the dominance of polyoxy components in the bulk sea-
water surfactants and different degrees of enrichment of more hydrophobic lipid
surfactants in the microlayer. Note that these particular spectra were chosen to il-
lustrate the range of composition observed and the impact on surface elasticity
(see Figure 4), not to represent bulk seawater, unslicked and slicked microlayers
generally
