We conducted four dives using the Urashima autonomous underwater vehicle (AUV) over three hydrothermal vent
fields (Snail, Archean, and Pika) within the South Mariana Trough in July 2009, and measure...
Analysis of ADCP data above a bottom observatory
ADCP sensitivity current lines inclination observatory’ s wake
2015/9/7
A 300-kHz ADCP was set on GEOSTAR, a six-m3 deep-sea observatory. It was operated with cells of 80 cm during a three-week test experiment at 42-m water depth in
the northern Adriatic sub-basin. Altho...
Measurement Method of Turbidity Depth Profiles using ADCP for Monitoring of Coastal Sea Area
Turbidity Depth Profiles ADCP Coastal Sea Area

A month-long circumnavigation of the Bering Sea basin in August 1991 was designed to study the basin-scale circulation. For the first time in this region vessel-mounted acoustic Doppler current profil...
船用声学多普勒海流剖面仪(ADCP)
多普勒海流剖面仪 海流测量仪 海洋测量仪器
2008/6/26
一、背景和意义：走航式声学多普勒海流剖面仪(ADCP)与其他海流计相比最大的特点是具有走航、遥测、多层的功能，就是说它具有走航遥测剖面流的能力，它的出现是海流测量技术的一次重大革命。目前中国有些部门已经引进了国外的ADCP。中国自行研制的国产ADCP，将替代进口，有着深远意义。该项目由国家海洋局海洋技术研究所完成，获国家海洋局科技进步二等奖。二.主要技术内容：ADCP是根据声学多普勒原理，用矢量...
走航式声学多普勒海流剖面仪（ADCP）
海流剖面仪 多普勒原理 海流计
2008/6/26
走航式声学多普勒海流剖面仪与其他海流计相比最大的特点是具有走航、遥测、多层的功能，也就是说它具有走航遥测剖面流的能力，它根据多普勒原理，用矢量合成法，遥测海流的垂直剖面分布。它对流场不产生任何扰动，并能实时显示流速剖面和存储数据及回放剖面时变曲线图等。项目创新：采用创新的频率跟踪、滤波跟踪技术，提高信噪比和仪器的可靠性。
ADCP在长江口悬沙输运观测中的应用
2007/8/24
声学多普勒流速剖面仪（ADCP）是近年来发展起来的一种用于测量流速的声学仪器，同时还可以通过建立回声强度和现场取得水样的回归关系式而获得悬沙浓度的数据。本文利用在长江口两个站位的高频观测数据，对现场取得的悬沙作粒度分析，在此基础上对枯季长江口地区悬沙输送机制和悬沙粒度对水动力的响应进行了分析和探讨。结果表明：平均流输运在整个悬沙输送中占主导地位，同时潮扩散和垂向扩散作用也是...
