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.
