Assessment and monitoring of ocean noise in Irish waters
(Environmental Protection Agency, 2013)This desk study was aimed to help Ireland meet the requirements of the Marine Strategy Framework Directive (MSFD) (2008/56/EC) under Descriptor 11: The introduction of energy, including underwater noise, is at levels that ... -
Assessment and monitoring of ocean noise in Irish waters
(Environmental Protection Agency, 2012)Anthropogenic noise is now recognised as a significant pollutant in the marine environment and there is a growing interest from the scientific community, policy makers and the general public in the effects of anthropogenic ... -
The use of deep water berths and the effect of noise on bottlenose dolphins in the Shannon Estuary cSAC
(2016)The Shannon Estuary on the west coast of Ireland is one of Europe’s premier deepwater berths catering for ships up to 200,000 deadweight tonnage. It is also Ireland’s only designated candidate special area of conservation ... -
Assessment of impulsive and continuous low- frequency noise in Irish waters
(Springer-Verlag, 2016)As part of the European Union Marine Strategy Framework Directive (MSFD), member states are required to address noise pollution in the marine environment under Descriptor 11. This study aimed to provide a practical desk-based ... -
Temporal and spatial variation in group size of bottlenose dolphins (Tursiops truncatus) in the Shannon Estuary, Ireland
(2016-09)Bottlenose dolphin group size is known to be determined by food availability, social interactions and predator defence. This paper analyses data gathered over seven years from dolphin tour boats operating in the Shannon ... -
Density estimates of harbour porpoises phocoena phocoena at eight coastal sites in Ireland
(2014)Single platform line-transect surveys with distance sampling were carried out at eight sites between July and September 2008 to derive density and abundance estimates of harbour porpoises. Over 37 days at sea, a total of ... -
Cetaceans in Irish waters: a review of recent research
(2009)To date, 24 cetacean species have been recorded in Irish waters. These are protected by a range of legislation, including the Whale Fisheries Act, the Wildlife Act and the EU Habitats Directive, which oblige Ireland to ... -
Mucus: aiding elasmobranch conservation through non-invasive genetic sampling
(Endangered Species Research, 2013-09)Large-scale genetic sampling by non-invasive methods is of vital importance for the conservation of vulnerable or elusive species. In the marine environment, non-invasive genetic sampling can provide a powerful alternative ... -
Modelling abundance hotspots for data-poor Irish sea rays
(Elsevier, 2015)Skates and rays represent one of the most vulnerable components of fish communities in temperate demersal fisheries such as the Irish Sea. They also tend to be data poor in comparison to commercially exploited teleost fish. ... -
Short note: the first confirmed successful refloat of a stranded bottlenose dolphin (Tursiops truncatus) in Ireland and subsequent resighting with a neonate
(2014-05)The article presents a study which discusses the refloating of bottlenose dolphins (Tursiops truncatus) and the subsequent resighting with a neonate in Ireland. Topics include the live-stranding events of a bottlenose ... -
Accounting for the effects of lipids in stable isotope (δ13C and δ15N values) analysis of skin and blubber of balaenopterid whales.
(John Wiley & Sons, 2012)RATIONALE: Stable isotope values (d13C and d15N) of darted skin and blubber biopsies can shed light on habitat use and diet of cetaceans, which are otherwise difficult to study. Non-dietary factors affect isotopic variability, ... -
Breeding habitat of poorly studied humpback whales (Megaptera novaeangliae) in Boa Vista, Cape Verde
(2013)The waters surrounding Cape Verde comprise one of two known breeding grounds for humpback whales in the North Atlantic. The population remains very small and has apparently failed to recover since the cessation of whaling ... -
Prey preferences of sympatric fin (Balaenoptera physalus) and humpback (Megaptera novaeangliae) whales revealed by stable isotope mixing models
(2013)Over-exploitation of top predators and fish stocks has altered ecosystems towards less productive systems with fewer trophic levels. In the Celtic Sea (CS), discards and bycatch levels have prompted concern about some ... -
Levels of persistent organic pollutants in eastern north Atlantic humpback whales
(2013)Blubber lipid concentrations of 14 organochlorine compounds and 10 polychlorinated biphenyls (PCB) were measured by gas chromatography with electron-capture detection in eastern North Atlantic humpback whales Megaptera ... -
An abundance estimate for humpback whales Megaptera novaeangliae breeding around Boa Vista, Cape Verde Islands
(2014)The abundance of humpback whales occurring around Boa Vista, Cape Verde Islands, was estimated by mark-recapture modelling. Photographs of markings on tail flukes of individual whales were collected during the breeding ... -
A flexible decision support tool for MSY-based MPA design
(2016)ICES WGEF recommends that demersal elasmobranchs be managed using spatial proxies 11 for Maximum Sustainable Yield. Here we combine escapement biomass – the percentage of the stock which must be retained each year to ... -
Insights into the trophic ecology of bottlenose dolphins (Tursiops truncatus) in Irish waters
(2015)The stomach contents of 12 bottlenose dolphins were examined. Ten of the 11 samples originated from dolphins that stranded on the west coast of Ireland between 1999 and 2011, while the remaining dolphin was bycaught. Ten ... -
A note on long-distance matches of bottlenose dolphins (tursiops truncatus) around the Irish coast using photo-identification
(International Whaling Commission, 2009-01)Images of 120 individual bottlenose dolphins from around the Irish coast were obtained from three photo-identification catalogues. Twenty three individuals were subsequently re-sighted, which is a re-sighting rate of 19%. ... -
Discrete or not so discrete: Long distance movements by coastal bottlenose dolphins in UK and Irish waters
(2012)The potential for long distance movements in common bottlenose dolphins (Tursiops truncatus) from six UK and Irish study sites was examined using photographs of natural markings. Here we provide the first evidence for ... -
Social structure within the bottlenose dolphin (Tursiops truncatus) population in the Shannon Estuary, Ireland
(2010)The Shannon Estuary is home to Ireland’s only known resident population of bottlenose dolphins (Tursiops truncatus) and is designated as a candidate Special Area of Conservation (cSAC) for this species. Proper conservation ...
