Chemical Variability in Ocean Frontal Areas: Results of a Workshop Conducted 19-22 September 1983

摘要

Between 19 and 22 September 1983, over 50 scientists met at the Naval Ocean Research and Development Activity (NORDA) to discuss issues related to the study of biological and chemical processes at oceanic fronts. In lieu of the publication of NORDA Report 78, this document has been printed to distribute the abstracts of the meeting. It was evident from the discussion of this workshop that rapid progress could be made in understanding chemical variability and processes at fronts, if a coordinated plan of research is pursued. The scope of the work to be done is multidisciplinary and extensive; this is a problem that would benefit greatly from a long-range, multi-investigator, coordinated study. The major components of such an investigation would include: 1) satellite and aircraft remote sensing, 2) physical characterization of the frontal system and its exchange processes, 3) measurements of chemical gradients and rates for substances participating in biological, photochemical, and solid phase processes, and 4) determination of the abundance and rates of biological activity associated with a front. It is likely that there is a wide range of frontal systems in the ocean that need to be distinguished. A coordinated investigation would provide the greatest advancement of knowledge for a given investment of resources.
