International Nusantara Stratification And Transport - INSTANT

INSTANT: A New International Array to Measure the Indonesian Throughflow. The INSTANT field program (International Nusantara Stratification And Transport) began in August 2003 and consists of a 3-year deployment of an array of moorings and coastal pressure gauges that will directly measure sea level and full depth in situ velocity, temperature, and salinity of the ITF. For the first time, simultaneous, multipassage, multiyear measurements will be available, and allow the magnitude and properties of the interocean transport between the Pacific and Indian Oceans to be unambiguously known. The array will also provide an unprecedented data set revealing how this complex and fascinating region responds to local and remote forcing at many timescales never before well resolved. Moorings were located at the following locations: (115 45.48, 8 26.77) (115 53.77, 8 24.56) (122 58.36, 11 31.76) (122 57.40, 11 22.19) (122 51.5, 11 16.6) (122 46.8, 11 9.67) (125 32.26, 8 32.33) (125 2.26, 8 24.04)

INSTANT计划：用于测量印度尼西亚贯穿流（Indonesian Throughflow）的新型国际观测阵列。
本INSTANT野外考察计划（全称：International Nusantara Stratification And Transport，努沙登加拉分层与输送国际计划）于2003年8月启动，将开展为期3年的观测部署，布设一系列锚系浮标与沿岸压力计，直接采集印度尼西亚贯穿流（ITF）的海平面变化、全剖面原位流速、温度与盐度数据。
这将首次实现同步、多断面、多年度的观测数据获取，从而能够明确确定太平洋与印度洋之间跨洋输送的强度与相关特性。
该观测阵列还将提供前所未有的数据集，揭示这片复杂且极具科研价值的区域如何响应局地与远程强迫作用，且其对应的时间尺度范围此前从未被清晰解析。
锚系浮标的布设位置如下：(115°45.48′, 8°26.77′)、(115°53.77′, 8°24.56′)、(122°58.36′, 11°31.76′)、(122°57.40′, 11°22.19′)、(122°51.5′, 11°16.6′)、(122°46.8′, 11°9.67′)、(125°32.26′, 8°32.33′)、(125°2.26′, 8°24.04′)
