Abstract:

Fatty acid and selected pigment distributions from stomach-oil deposit WMM7. Pigments are reported according to the absorbance at 4 key wavelengths (e.g. P410 = absorbance at 410 nm). Absorbances are reported normalised to extracted mass of stomach-oil deposit (abs g-1) and normalised to total organic carbon content (abs gTOC-1).
