    "description": "Grey seals Halichoerus grypus are among the rarest seals in the world: the UK population represents about 40% of the world population and 95% of the EU population. Globally, there are three reproductively-isolated stocks of grey seal: a west Atlantic (northern North American) stock; a Baltic stock; and an East Atlantic stock. The latter extends from Iceland and northern Norway southwards to northern France, with the majority breeding around Great Britain and Ireland. \r\n\r\nThe extent of connectivity within the Irish Sea grey seal (Halichoerus grypus) population has been investigated every year since 2006 using photo-identification and bio-logging techniques.\r\n\r\nThe purpose of this data capture was to survey Bardsey seal population fluctuations. Surveys were undertaken by both trained staff and volunteers.",
