The World Ocean Circulation Experiment (WOCE) was a component of the international World Climate Research Program, and aimed to establish the role of the World Ocean in the Earth's climate system. WOCE's field phase ran between 1990 and 1998, and was followed by an analysis and modeling phase that ran until 2002.〔(Ocean Circulation and Climate: World Ocean Circulation Experiment. Retrieved 7 December 2013. )〕 When the WOCE was conceived, there were three main motivations for its creation. The first of these is the inadequate coverage of the World Ocean, specifically in the Southern Hemisphere. Data was also much more sparse during the winter months than the summer months, and there was—and still to some extent—a critical need for data covering all seasons. Secondly, the data that did exist was not initially collected for studying ocean circulation and was not well suited for model comparison. Lastly, there were concerns involving the accuracy and reliability of some measurements. The WOCE was meant to address these problems by providing new data collected in ways designed to “meet the needs of global circulation models for climate prediction.” 〔(The World Ocean Circulation Experiment. J.D. Woods. Retrieved 7 December 2013. )〕 ==Goals== Two major goals were set for the campaign.〔 1. Develop ocean models that can be used in climate models and collect the data necessary for testing them. Specifically, understand: * Large scale fluxes of heat and fresh water * Dynamical balance of World Ocean circulation * Components of ocean variability on months to years * The rates and nature of formation, ventilation and circulation of water masses that influence the climate system on time scales from ten to one hundred years 〔(Scientific Plan for the World Ocean Circulation Experiment. J.D. Woods. Retrieved 7 December 2013. )〕 In order to achieve Goal 1, the WCRP outlined and established Core Projects that would receive priority. The first of these was the “Global Description” project, which was meant to obtain data on the circulation of heat, fresh water and chemicals, as well as the statistics of eddies. The second project—“Southern Ocean”—placed particular emphasis on studying the Antarctic Circumpolar Current and the Southern Ocean’s interaction with the World Ocean. The third and final Core Project serving goal one was the “Gyre Dynamics Experiment.” The second and third of these focuses are designed specifically to address the ocean’s role in decadal climate changes. Initial planning of the WOCE states that achievement of Goal 1 would involve “strong interaction between modeling and field activities,” which are described further below. 2. Find the representativeness of the dataset for long-term behavior and find methods for determining long-term changes in ocean currents. Specifically: * Determine representative of specific WOCE data sets * Identify those oceanographic parameters, indices and fields that are essential for continuing measurements in a climate observing system on decadal time scales * Develop cost effective techniques suitable for deployment in an ongoing climate observing system〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「World Ocean Circulation Experiment」の詳細全文を読む スポンサード リンク
