First Steps towards the Automated Detection of Underwater Vocalisations of Grey Seals (Halichoerus grypus) in the Blasket Islands, Southwest Ireland
نویسندگان
چکیده
Underwater vocalisations of grey seals (Halichoerus grypus) were recorded by static acoustic monitoring (SM2M, Wildlife Acoustics) in the vicinity a colony located at White Strand beach on Great Blasket Island, southwest Ireland during pre-breeding and breeding seasons. Grey seal first classified across nine different categories based aural visual characteristics spectrograms, providing an repertoire for seals. This classification was further investigated applying tree analysis, resulting five initial groups being selected. Furthermore, comparison two common approaches detection extraction from files done using software Raven Pro PAMGuard. The outputs this study will present essential step towards development protocol underwater Irish waters elsewhere.

Gas exchange of captive freely diving grey seals (Halichoerus grypus).
When at sea, phocids dive for long periods and spend a high percentage of their time submerged. This behaviour requires some combination of an increased oxygen storage capacity, rapid oxygen loading at the surface and reduced oxygen utilisation when submerged. To assess these adaptations, breath-by-breath ventilation was studied in four adult grey seals (two male, two female, 160-250 kg), freel...
متن کاملGeographic variation of the major histocompatibility complex in Eastern Atlantic grey seals (Halichoerus grypus).
Pathogen-driven balancing selection maintains high genetic diversity in many vertebrates, particularly in the major histocompatibility complex (MHC) immune system gene family, which is often associated with disease susceptibility. In large natural populations where subpopulations face different pathogen pressures, the MHC should show greater genetic differentiation within a species than neutral...
متن کاملIn-Air Evoked Potential Audiometry of Grey Seals (Halichoerus grypus) from the North and Baltic Seas
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 assessment. Using in-ear headphones with adapted ear inserts allowed for the measurement of auditory brainstem responses (ABR) on sedated grey seals e...
متن کاملBy-Catch of Grey Seals (Halichoerus grypus) in Baltic Fisheries—A Bayesian Analysis of Interview Survey
Baltic seals are recovering after a population decline. The increasing seal stocks cause notable damage to fisheries in the Baltic Sea, with an unknown number of seals drowning in fishing gear every year. Thus, sustainable seal management requires updated knowledge of the by-catch of seals--the number of specimens that die in fishing gear. We analyse the by-catch of grey seals (Halichoerus gryp...
متن کاملGrey seals , Halichoerus grypus , of the Dee Estuary and observations on a characteristic skin lesion in British seals
Grey seals on the West Hoyle Bank feed on a variety of fish and have a high incideince of dermal lesions, often associated with emaciation and nematode parasite infection. Corynebacterium phocae has been isolated from an active lesion. The significance of' large numbers of seals in the Dee Estuary bearing lesions is discussed and the occurrence of seals with lesions elsewhere in British waters ...
