JNCC advocates an international cooperative approach for long term surveillance and monitoring of cetaceans. The Joint Cetacean Protocol (JCP) has been set up with the aim of delivering information on the distribution, abundance and population trends of cetacean species occurring in the North Sea and adjacent sea regions. This reports present the revised phase III analysis of the available data resources.
 

Introduction

 

Effort-linked sightings data contained within the Joint Cetacean Protocol data resource were used to estimate spatio-temporal patterns of abundance for seven species of cetacean over a 17-year period from 1994 – 2010 over a 1.09 million km2 prediction region from 48° N to c. 64° N and from the continental shelf edge west of Ireland to the Kattegat in the east. The species were harbour porpoise Phocoena phocoena, minke whale Balaenoptera acuturostrata, bottlenose dolphin Tursiops truncatus, short-beaked common dolphin Delphinus delphis, Risso’s dolphin Grampus griseus, white-beaked dolphin Lagenorhynchus albirostris and Atlantic white-sided dolphin Lagenorhynchus acutus. There were 38 data sources with data from at least 542 distinct survey platforms (ships and aircraft) representing over 1.05 million km of effort.
