The Sea Mammal Research Unit carries out fundamental, cutting-edge research on marine mammals in many different subject areas. This research is carried out worldwide with a core objective of understanding the causes and consequences of changes in populations. With ever increasing pressure on the world's oceans and it resources, marine mammals are consequently often impacted by man's marine activities. One of our main aims is to therefore determine the nature, magnitude and significance of these expanding interactions.

    The number of Mexico’s endemic porpoise, the vaquita (Phocoena sinus), is collapsing primarily due to bycatch in illegal gillnets set for totoaba (Totoaba macdonaldi), an endangered fish whose swim bladders are exported ...
  • The challenges of analyzing behavioral response study data : an overview of the MOCHA (Multi-study OCean acoustics Human effects Analysis) project 

    Harris, Catriona M; Thomas, Len; Sadykova, Dinara; De Ruiter, Stacy Lynn; Tyack, Peter Lloyd; Southall, Brandon L.; Read, Andrew J.; Miller, Patrick (Springer Science and Business Media, 2016) - Conference item
    This paper describes the MOCHA project which aims to develop novel approaches for the analysis of data collected during Behavioral Response Studies (BRSs). BRSs are experiments aimed at directly quantifying the effects of ...
  • Sperm whale codas may encode individuality as well as clan identity 

    Oliveira, Cláudia; Wahlberg, Magnus; Silva, Mónica A.; Johnson, Mark; Antunes, Ricardo; Wisniewska, Danuta M.; Fais, Andrea; Gonçalves, João; Madsen, Peter T. (2016-05) - Journal article
    Sperm whales produce codas for communication that can be grouped into different types according to their temporal patterns. Codas have led researchers to propose that sperm whales belong to distinct cultural clans, but it ...
  • Adapting a computational multi agent model for humpback whale song research for use as a tool for algorithmic composition 

    Mcloughlin, Michael; Ingram, Simon; Rendell, Luke Edward; Lamoni, Luca Ubaldo; Kirke, Alexis; Garland, Ellen Clare; Noad, Michael; Miranda, Eduardo (Hochschule für Musik und Theater Hamburg, 2016-08-31) - Conference item
    Humpback whales (Megaptera Novaengliae) present one of the most complex displays of cultural transmission amongst non-humans. During breeding seasons, male humpback whales create long, hierarchical songs, which are shared ...
