| dc.description.abstractEn | A new approach is described to identify the dominant process (physical versus biological) in a pelagic marine ecosystem, from simple biological oceanographic field variables. The approach is based on quantification of the matching (M) between phytoplankton production (P) and losses, from held estimates of chlorophyll a (Chl) and P. Coefficient Ail is estimated for a wide range of oceanic and coastal environments and of trophic characteristics, using data from the literature. Results show that M characterizes the dominance of physical versus biological processes in pelagic systems. The coefficient may be especially useful as a means for extracting process information on pelagic marine ecosystems from large data sets of Chi and P, e.g. recorded by moored instruments or provided by satellite images of ocean colour. | |
