North Pole Environmental Observatory (NPEO) Oceanographic Mooring Data

This data set, acquired with an oceanographic bottom-anchored mooring, includes sea-ice draft and depth data, conductivity, temperature, pressure, salinity, and ocean current measurements such as speed and direction. Each mooring contains vertically distributed instruments, which measure ocean properties at fixed depths and record data internally. These data are retrieved annually when the mooring is recovered. Located on the Pole Abyssal Plain about 50 kilometers from the North Pole, the original 2001 mooring was chosen because it provided a suitable landing site for the supporting aircraft. Ocean depth was approximately 4300 m. Data were recorded half-hourly to hourly. The North Pole Environmental Observatory (NPEO) is a year-round, automated scientific observatory, deploying various instruments each April in order to learn how the world's northernmost sea helps regulate global climate. It consists of a set of unmanned scientific platforms that record oceanographic, cryospheric, and atmospheric data throughout the year. Data are in ASCII text format.

本数据集通过海洋学海底锚定系泊装置（oceanographic bottom-anchored mooring）获取，涵盖海冰吃水数据、水深数据、电导率、温度、压力、盐度数据，以及流速、流向等海流观测数据。每套系泊装置均搭载垂直分布的观测仪器，可在固定深度处测量海洋环境参数并实现内置数据存储。待系泊装置回收时，即可按年取回存储的观测数据。该首套系泊装置于2001年布设于距北极点约50公里的北极深渊平原（Pole Abyssal Plain），其选址原因为可为保障作业的飞行器提供合适的着陆点，该处海洋水深约4300米。数据按每半小时至一小时的间隔记录。北极点环境观测站（North Pole Environmental Observatory, NPEO）是一套全年无人值守的自动化科学观测站，每年4月会布设各类观测仪器，旨在探究全球最北端海域如何调节全球气候。该观测站由多套无人科学观测平台组成，可全年连续记录海洋学、冰冻圈与大气圈相关观测数据。数据集采用ASCII文本格式存储。
