In-air evoked potential audiometry of grey seals (Halichoerus grypus) from the North and Baltic Seas. [PDF]
PLoS ONE, 2014 In-air anthropogenic sound has the potential to affect grey seal (Halichoerus grypus) behaviour and interfere with acoustic communication. In this study, a new method was used to deliver acoustic signals to grey seals as part of an in-air hearing ...

Highly Pathogenic Avian Influenza A(H5N8) Virus in Gray Seals, Baltic Sea
Emerging Infectious Diseases, 2019 We detected a highly pathogenic avian influenza A(H5N8) virus in lung samples of 2 gray seals (Halichoerus grypus) stranded on the Baltic coast of Poland in 2016 and 2017. This virus, clade 2.3.4.4 B, was closely related to avian H5N8 viruses circulating
