Abstract:
In order to provide a better understanding of the fate of sedimentary chlorophyll and chlorophyll degradation products in all kinds of environments, we have recently expanded our studies to include examination of sediments returned from Legs which are not rich in organic matter, nor are even primarily biogenic. Eight core samples from the Mariana Basin and Trench, obtained from DSDP Leg 60, were analyzed for products of chlorophyll diagenesis. To date, the sediment samples from the South Philippine Sea have been the most organically barren examined. Through elimination of the bias of examining only sediments rich in organic matter, we hope that the fate of chlorophyllous material on a more global scale will eventually be elucidated.

| 11 | Tetrapyrrole pigment yield | TPY | ng/g | Baker, Earl W | Calculated | Calculated as chlorins, using the specific absorption coefficient for pheophytin-a (alpha = 63.7). Trace implies definite presence of pigment but in extremely low quantities and unable to be purified for valid quantitation. <0.1 = traces, #0 = void; #0.1 = trace unidentified metalloporphyrin. |
| 12 | Pigment yield index | PYI | Baker, Earl W | Calculated | Calculated as µg pigment/g sediment, dry weight divided by percentage of organic carbon, dry weight |
