The Drake Passage High Density XBT/XCTD Program

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考察船劳伦斯·M·古尔德在每次穿越时获得的高密度区段组成，使用一次性水温仪，辅之以消耗性电导率-温度-深度探头。这些信息将导致建立一个高质量的数据库，用来研究季节信号的穿透程度和深度、与大气强迫的联系以及年际变化的影响，例如与南极绕极波有关的影响。这些章节将补充自1996年9月以来获得的大约20个章节。探测器由科学船上的人员在每次巡航中发射。持续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。

0003618Sprintall This 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. These sections will supplement the approximately twenty sections have been obtained since September 1996. The probes 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.***
