Mitigation of effects of high power sonars on marine mammals

Updated 2003-06-25

• This proposal is to develop a reliable method for forecasting the occurrence of marine mammals based on time of year, location and oceanographic conditions. • The work will exploit components of existing NERC-funded research within the core science programmes of SMRU and SAMS. • Pre-existing data on marine mammal aggregations lead us to believe that the proposed method has a high probability of success. • The main study area will be the Sea of the Hebrides and the Minch. • Historical data on marine mammal sightings will be supported by an observational programme, including the use of acoustics and satellite and radio tags. • Simultaneous oceanographic data will be collected during the above programme, supplementing the extensive SAMS archive of time-series from this area. • A proposed operational monitoring network in the southern Minch will be adapted to add acoustic observations to the planned suite of physical and chemical sensors. • The datasets will be analysed using a variety of statistical techniques to yield a practical relationship between observables (local oceanographic conditions, season, location) and species abundance. • The validity of this relationship as an operational tool will be tested in a variety of scenarios. • The work is expected to run from the summer of 2002 to the summer of 2005.
