"Deepwater CTD - d93g063.bdo.nc - 27.92N, -90.51W - 1993-11-10"

The Minerals Management Service (MMS) of the U. S. Department of the Interior funded the Deepwater Physical Oceanography Reanalysis and Synthesis of Historical Data Study in the Gulf of Mexico. MMS awarded the contract to the Texas A&M Research Foundation in July 1998. The basic study area is bounded by the shelf edge and the 25DGN latitude, which is the southern boundary; it extends from sea surface to sea floor. MMS has four objectives for the study. First is to create an inventory of physical oceanographic data and compile it into a single database on a CD-ROM. Second is to conduct analyses and interpretations of the physical oceanographic data to identify physical processes and phenomena. Third is to produce a climatology of the processes from available data and analyses and to prioritize the processes in terms of importance to improved understanding, simulation, and prediction of deepwater circulation. Fourth is to provide criteria and constraints useful in design of future field observations and numerical modeling efforts. Study results will provide MMS with information needed to direct its resources more efficiently and effectively in the review and assessment of potential environmental impacts of offshore oil and gas operations in the deepwater Gulf of Mexico.

美国内政部矿产资源管理局（MMS）资助了墨西哥湾深海物理海洋学历史数据再分析和综合研究项目。MMS于1998年7月将合同授予德克萨斯A&M研究基金会。研究的基本区域由大陆架边缘和25DGN纬度界定，该纬度为南部边界；该区域范围从海面延伸至海底。MMS对该研究设定了四个目标。首先，编制物理海洋学数据的清单，并汇总至单一生成数据库中，存储于CD-ROM。其次，对物理海洋学数据进行分析和解释，以识别物理过程和现象。第三，从可用数据和数据分析中生成过程气候学，并按其对深化对深海环流的理解、模拟和预测的重要性进行过程优先级排序。第四，提供对未来现场观测和数值模拟工作设计有用的准则和限制条件。研究结果的产出将为MMS提供所需信息，以更高效、更有效地指导其资源在审查和评估墨西哥湾深海海上石油和天然气作业潜在环境影响方面的工作。
