9726003PetersonThis project is a study of the seasonal variability and long term change of the upper ocean structure of the Drake Passage. It consists of high density sections obtained on each crossing by the U.S. Antarctic Program's research vessel Laurence M. Gould, using expendable bathythermographs, supplemented by expendable conductivity-temperature-depth probes.This information will lead to the establishment of a high quality data base with which to study the magnitude and depth of penetration of the seasonal signals, connections to atmospheric forcing, and the effects of interannual variations such as those associated with the Antarctic Circumpolar Wave. Six sections were obtained from the R/V Polar Duke between September 1996 and April 1997. The probes are being supplied by the institution with other funds, and are launched by the scientific shipboard personnel on each cruise. The continuing data analysis is carried out in cooperation with the Argentine Antarctic Institute in Buenos Aires.***

9726003 peterson这个项目是对德雷克海峡上层海洋结构的季节变化和长期变化的研究。它由美国南极计划的研究船劳伦斯·m·古尔德（Laurence M. Gould）在每个交叉点获得的高密度剖面组成，使用消耗性深海温度仪，辅以消耗性电导率-温度-深度探测器。这些资料将导致建立一个高质量的数据库，用以研究季节信号的穿透强度和深度、与大气强迫的联系以及年际变化的影响，例如与南极环极波有关的年际变化。1996年9月至1997年4月期间从R/V极地公爵号获得了6个剖面。这些探测器由该机构提供其他资金，并由每次巡航的科学船上人员发射。继续进行的数据分析是与布宜诺斯艾利斯的阿根廷南极研究所合作进行的
