79North Ocean Data

Last updated (Loading...)

In August 2016, we deployed an ice-tethered mooring in sea ice near the floating ice tongue at 79North glacier. This mooring measures temperature and salinity in the ocean water beneath the floating ice tongue. This data will be important for understanding how ocean processes affect glacier behaviour.

The data are transmitted from the glacier daily and made available via the plots below.



November 16, 2016 — After relaxing downward about 0.5 meters, the direction of mooring drift has veered from northeast to north-northwest

November 7, 2016 — Pressure at all instruments has fallen by about 2.15 dbar, consistent with the entire mooring being hoisted 2 meters

October 21, 2016 — Salinity measurements from the 500 m sensor (Aquadopp 4) appear to have returned to normal

October 12, 2016 — Salinity measurements from the 500 m sensor (Aquadopp 4) are giving anomalously low values
