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.

北航道测量项目（North Passage Channel Measurements, NP-ChaM）是一项综合性多年野外实地观测项目，专为加深对中国长江口核心通航航道北航道内的水动力与泥沙动力学规律的认知而设计并实施。该项目共设置8个观测站点，观测周期跨越四年，累计时长50天，涵盖两个枯季与两个洪季。研究团队在海床布设了多套搭载多类观测仪器的三脚架式观测系统，以可靠监测床面附近的物理过程。
