L. A. Codispoti’s recent research activities are concentrated on the following three activities:

1- The global oceanic fixed-N and Nitrous oxide budgets.  His most recent paper on this subject  (Codispoti, 2007) is available on this web site, as is an older paper that he has been asked to post because it is in a volume that is difficult for some folks to obtain (Codispoti et al., 1992).
2 - A second active line of research involves working with a team to provide a synthesis of marine primary production in the Arctic Ocean and its adjacent and its adjacent and marginal seas.  His team’s activities under this project are concentrated on producing a high quality nutrient data base for the region that enables inferences on primary production to be made from changes in nutrient concentrations.  A web site that  gives more information on this project is available at: http://psc.apl.washington.edu/cgi-bin/PPobs/PPobs.cgi





This figure (right) was generated using the data in the nutrient data base for the Arctic Ocean and its seas that is being created by the team led by L.A. Codispoti as part of a collaborative project to provide a synthesis of what is known about primary production (photosynthetic production) in the Arctic Ocean and its adjacent seas.  It shows the large differences in nitrate + nitrite (N+N): phosphate (PO4) ratios in Arctic waters that originate in the Atlantic vs the Pacific.

3 - A third line of research involves developing instruments and systems that facilitate real-time, autonomous acquisition and posting of  chemical oceanographic data.  This research is conducted in collaboration with Green Eyes Observing LLC: http://greeneyesobserving.com/.  One product is a “water to web” system that can integrate data from a suite of sensors and post edited data on a web site within 2 hours of autonomous collection: http://greeneyesobserving.com/water2web.html.  Another product is an autonomous profiling system (CLASP) that is being designed to operate for one year without requiring servicing or calibration: http://greeneyesobserving.com/CLASP/ .   Finally we are developing a device designed to alleviate  the problem of biofouling that plagues many sensors: http://greeneyesobserving.com/probe.html
