Pentland Firth
The Pentland Firth The Pentland Firth is the channel of water that separates the Orkney archipelago from Caithness, the northern most county of Scotland. It is deep, wide, and famously dangerous to cross, even with modern boats and navigation systems. From the ferry crossing from Caithness to South Ronaldsay interesting surface phenomena indicate what is happening beneath the hull of the boat. Flat shiny areas of water commonly suggest an upwelling mix of currents , while whirlpools imply water being drawn down into the murky deeps. "The Pentland Firth’s eastern approach hosts intricate sediment transport pathways. Time-averaging the modelled flow field revealed the recirculatory nature of the residual flow also reflected by the inferred sediment transport field identified via timeseries bathymetric analysis. The Pentland Firth (PF), located between mainland Scotland and Orkney, is an area of the UK continental shelf (UKCS) that experiences extreme ...
