Dataset of North Passage Channel Measurements (NP-ChaM)

A comprehensive multi-year field campaign, the North Passage Channel Measurements (NP-ChaM), was designed and executed to enhance our understanding of the hydro- and sediment dynamics in the North Passage, the primary navigational channel of the Changjiang Estuary, China. The NP-ChaM campaign comprised eight observational sites and spanned 50 days, distributed over four years, including two dry seasons and two wet seasons. A series of tripod systems, equipped with multiple instruments, were deployed on the seabed to monitor near-bed physical processes reliably.

为深化对中国长江口主要通航航道——北航道的水动力与泥沙动力学特征的认识，科研团队设计并实施了一项综合性多年野外观测项目：北航道测量项目（North Passage Channel Measurements，缩写为NP-ChaM）。该项目共布设8个观测站点，总观测时长50天，观测周期分布于4年时间内，涵盖2个枯季与2个洪季。研究团队在海底部署了多套搭载多种观测仪器的三脚架式观测系统，以可靠监测近底物理过程。

背景概述

该数据集是2015-2018年在长江口北槽（中国）进行的多年度综合野外观测数据，涵盖干湿季节，包括八个观测站点和50天的测量。数据通过部署在海底的多个仪器（如ADCP、ADV等）采集，专注于近床水动力和沉积物浓度动态研究，旨在增强对主要航道环境过程的理解。
