    The European Union (EU) Habitats Directive requires Member States to monitor and maintain at favourable conservation status those species identified to be in need of protection, including all cetaceans. In July 2005 we ...
  • Investigation into a prominent 38 kHz scattering layer in the North Sea 

    Mair, Angus MacDonald (University of St Andrews, 2008-07) - Thesis
    The aim of this study was to investigate the composition of an acoustic scattering layer in the North Sea that is particularly strong at 38 kHz. A full definition of the biological composition of the layer, along with its ...
  • Seals, sandeels and salmon : diet of harbour seals in St. Andrews Bay and the Tay Estuary, southeast Scotland 

    Sharples, Ruth Jemma; Arrizabalaga, B; Hammond, Philip Steven (2009) - Journal article
    Harbour seal populations have declined by up to 40% around northern and eastern Britain since 2000 due to unknown causes; prey availability is one important factor that could be contributing to the decline. We estimate the ...

    Fässler, Sascha M.M. (University of St Andrews, 2010-11-30) - Thesis
    Acoustic survey techniques are widely used to quantify abundance and distribution of a variety of pelagic fish such as herring (Clupea harengus). The information provided is becoming increasingly important for stock ...
