TL;DR: The entire EU Atlantic continental shelf was surveyed in July 2005 to generate robust estimates of abundance for harbour porpoise and other cetacean species, and abundance in 2005 was similar to that in 2004.

TL;DR: New and revised data for the phocine distemper virus (PDV) epidemics that resulted in the deaths of more than 23 000 harbour seals Phoca vitulina in 1988 and 30,000 in 2002 are presented and it is suggested that grey seal populations could act as reservoirs for PDV if infection rates in sympatric species are lower than in harbour seals.

TL;DR: In this article, the authors investigated the potential impact of the construction of one of the first major, offshore wind farms (>100 MW) on harbour porpoises Phocoena phocoenas by means of acoustic porpoise detectors (T-PODs) monitoring porcoise echolocation activity.

TL;DR: Steel monopile foundations for offshore wind turbines were driven into hard sand in shallow water at Horns Reef, the North Sea, and impulsive sounds generated had high sound pressures and a strong low frequency emphasis but with significant energy up to 100 kHz.

TL;DR: It is reported that porpoises forage nearly continuously day and night, attempting to capture up to 550 small fish prey per hour with a remarkable prey capture success rate of >90%, which means that they must forage almost continually to meet their metabolic demands with such small prey, leaving little margin for compensation.
