The Brahan HF Radar Demonstration Project (http://www.thebrahanproject.com/) is a collaboration between Marine Scotland Science, Qualitas Remos, and others, to show the application of High Frequency (HF) Radar in Scottish waters. This data collection comprises the HF Radar measurements of currents and waves in the area around Orkney and Shetland. The data collected during the Brahan project is vast and a number of projects are ongoing to further explore features identified in this initial data exploration.
