Tiree Passage Time Series: Oceans 2025 Theme 10, SO12

— filed under:

Temperature, salinity and flow variability on the north-west European Shelf west of Scotland have been monitored by SAMS since 1981. Analyses are derived from a range of marine and atmospheric data sources which together comprise a “proto-observatory” of the European Shelf to the west of the Scottish mainland.

The main time series are from a current meter mooring which has been maintained on the northwest European continental shelf since June 1981 (the Tiree Passage mooring), and a hydrographic section repeated at least annually across the shelf at ~56°N since 1975 (The Ellett Line).
