The QPE Pilot Study took place 22 Aug – 13 Sep 2008. The experiment was designed to acquire baseline hydrographic data for future experiments and to explore acoustic propagation properties in the intensive acoustic area. Nowcast and forecast products with dynamics and uncertainty descriptions and adaptive sampling recommendations were provided for physical (T, S, velocity) and acoustical (sound speed and transmission loss) variables for the period 6 – 12 September 2008.
