Chlorin acid surface sediments

Marine Surface Sediments.. (0-2m) sediments beneath the highly productive upwelling regions in the Gulf of California and off the coast of Peru were chromatograph cally separated (see "Experimental") into (a) pheophytins, (b) pheophorbides (viz. mono carboxylic acids) and (c) chlorin acids (I.e. di-/tri-acids). Table II contains the result of these preliminary analyses and includes the concentration of pigments, present depositional environment and sample depth. [Pg.113]

In general, pheophorbides and chlorin acids have become the dominant tetrapyrrole pigments In surface sediments, relative to upper water column detritus. The averaged values for the relation-... [Pg.113]
