Ocean Primary Productivity Study

Welcome to the IMCS Ocean Primary Productivity Team's (OPPT) home page. We have constructed this web site with the intent of providing:

• Access to datasets of primary productivity measurements based on ¹⁴C uptake and stimulated fluorescence techniques, with the hope that these data will be used for productivity model development snd testing,
• Computer source code, input data fields, and ocean productivity estimates for the Vertically Generalized Production Model (VGPM) developed by the OPPT, and
• Information on activities of the NASA-sponsored Ocean Primary Productivity Working Group (OPPWG), which has been conducting round-robin algorithm testing exercises since 1994 to compare, in an investigator-independent manner, the performence of various productivity models with the intent of establishing a NASA resident "consensus" algorithm for the routine generation of ocean productivity maps.

We view the productivity databases, VGPM, "consensus" algorithm, as well as this web site, as continuously evolving entities. As such, we hope you will participate in their evolution by providing us with productivity measurements data and/or any helpful suggestions.
