From page 37...
... The long time scale of oceanic heat anomalies may be an important factor for climate forecasting, but the length of time needed to describe and understand these anomalies presents a problem in experimental design. Furthermore, events like the Southern Oscillation occur sporadically (typically at 2- to 10-year intervals)
From page 38...
... , in a series of workshops led by Henry Stommel, recommended the establishment of "phantom weather ships." In this program, commercial ships would collect measurements as they passed certain designated points in the ocean. The resultant time series of observations would provide regular samples at fixed locations and function much as the Ocean Weather Stations did but without the great expense of maintenance.
From page 39...
... In a recent study on the effects of atmospheric carbon dioxide chaired by Joseph Smagorinsky (Climate Board, 1982) , an ocean monitoring system for early detection of climate change was recommended.
From page 40...
... Although exploratory time series are a useful preliminary step, ocean climate research programs will need a reliable source of routine global data. There thus ultimately must be a commitment to ocean climate monitoring.
From page 41...
... Some support should go as well to the development of techniques and instruments for ocean monitoring. Techniques should include means for measuring the annual cycle and interannual variability of the upper-ocean heat budget, for volumetric surveys of water-mass properties as a means for determining trends, and for measuring the fluxes of mass, heat, salt, and tracers associated with the circulation of water and its exchange with the surface layers.
From page 42...
... considered a comprehensive range of topics: existing data bases, improving ocean circulation models, network design, large-scale experiments, altimetric and hydrographic surveys, national and institutional programs, instruments and methods, and data management. Subsequent to that meeting, however, significant additional steps have not been taken.
From page 43...
... 43 need for ocean climate monitoring, the implementation of a pilot network, and the use of the system to develop prototype products. If this is done in cooperation with IGOSS, it might encourage IGOSS to take over and run whatever is developed.
