Development of Autonomous Lagrangian Circulation Explorers for the World Ocean Circulation Experiment (WOCE)

自主拉格朗日环流探测器（alace）是一种水下浮子，它周期性地上升到水面，由Argos卫星系统定位，然后返回深处继续跟随洋流。它们将用于绘制海洋环流图，并在世界海洋环流实验（WOCE）中具有特殊价值。建议开发和演示使用这些目前正在开发的浮筒的操作能力。建议的工程是(a)将操作深度从1500米扩展到4000米，(b)扩大数据中继能力，允许卫星在每次上升时中继剖面数据，以及(c)增加RAFOS声学跟踪。拟议的实地作业包括(a)一系列当地寿命试验，(b)展示从机会商船上发射的能力，以及(c)在热带大西洋部署25个alace，其中将使用浮标来描述南极中间水的跨赤道流动。作为向WOCE操作迈进的一步，研究人员将被邀请建议使用斯克里普斯开发的ALACE能力的其他项目。

Autonomous Lagrangian Circulation Explorers (ALACEs) are current-following subsurface floats which periodically rise to the surface to be located by the Argos satellite system and then return to depth to continue following currents. They are intended to be used in mapping the oceanic general circulation and will be of particular value in the World Ocean Circulation Experiment (WOCE). It is proposed to develop and demonstrate an operational capability to use these presently developmental floats. Proposed engineering are (a) extending operational depth improvements from 1500 m to 4000 m, (b) expansion of data relay capacity to permit satellite relay of profile data on each ascent, and (c) addition of RAFOS acoustic tracking. Proposed field operations include (a) series of local tests of longevity, (b) demonstration of a capability to lauch from commerical ships of opportunity, and (c) a deployment of 25 ALACEs in the tropical Atlantic in which floats will be used to describe cross-equatorial flow of Antarctic Intermediate Water. As a step toward WOCE operations, investigator will be invited to suggest other programs to use the ALACE capability developed at Scripps.
