A detailed assessment of the wave energy resource at the atlantic marine energy test site
(MDPI AG, 2016-11-18)Wave characteristic assessments of wave energy test sites provide a greater understanding of prevailing wave conditions and are therefore extremely important to both wave energy test site operators and clients as they can ... -
A model prediction of the yield of cloud condensation nuclei from coastal nucleation events
(Wiley-Blackwell, 2002-01-01)[1] The formation and evolution of new particles during coastal nucleation events are examined using the aerosol dynamic and gas-phase chemistry model AEROFOR2. Coastal regions are known to be a strong source of natural ... -
A multi-decade record of high-quality <i>f</i>co<sub>2</sub> data in version 3 of the surface ocean co<sub>2</sub> atlas (socat)
(Copernicus GmbH, 2016-09-15)The Surface Ocean CO2 Atlas (SOCAT) is a synthesis of quality-controlled fCO(2) (fugacity of carbon dioxide) values for the global surface oceans and coastal seas with regular updates. Version 3 of SOCAT has 14.7 million ... -
Chemical and physical characteristics of aerosol particles at a remote coastal location, mace head, ireland, during namblex
(Copernicus GmbH, 2006-08-09)A suite of aerosol physical and chemical measurements were made at the Mace Head Atmospheric Research Station, Co. Galway, Ireland, a coastal site on the eastern seaboard of the north Atlantic Ocean during NAMBLEX. The ... -
Detection of salmonid alphavirus rna in celtic and irish sea flatfish
(Inter-Research Science Center, 2014-04-23)Pancreas disease (PD) caused by the salmonid alphavirus (SAV) has been the most significant cause of mortalities in Irish farmed salmon Salmo salar L. over the past decade. SAV is a single-strand positive-sense RNA virus, ... -
Distribution and biological characteristics of atlantic salmon (salmo salar) at greenland based on the analysis of historical tag recoveries
(Oxford University Press (OUP), 2012-06-13)In this study, we examined 5481 records of tag recoveries at Greenland from a new tagging database held by ICES that contains information on salmon tagged in Canada, France, Faroes, Greenland, Iceland, Ireland, Norway, ... -
Do anthropogenic, continental or coastal aerosol sources impact on a marine aerosol signature at mace head?
(Copernicus GmbH, 2014-10-10)Atmospheric aerosols have been sampled and characterised at the Mace Head north-east (NE) Atlantic atmospheric research station since 1958, with many interesting phenomena being discovered. However, with the range of new ... -
Facets of diazotrophy in the oxygen minimum zone waters off peru
(Springer Nature, 2014-05-09)Nitrogen fixation, the biological reduction of dinitrogen gas (N-2) to ammonium (NH4+), is quantitatively the most important external source of new nitrogen (N) to the open ocean. Classically, the ecological niche of oceanic ... -
Historical gene flow constraints in a northeastern atlantic fish: phylogeography of the ballan wrasselabrus bergyltaacross its distribution range
(The Royal Society, 2017-02-01)The distribution and demographic patterns of marine organisms in the north Atlantic were largely shaped by climatic changes during the Pleistocene, when recurrent glacial maxima forced them to move south or to survive in ... -
Lithosphere-asthenosphere interaction beneath ireland from joint inversion of teleseismic p-wave delay times and grace gravity
(Oxford University Press (OUP), 2011-01-28)P>The nature and extent of the regional lithosphere-asthenosphere interaction beneath Ireland and Britain remains unclear. Although it has been established that ancient Caledonian signatures pervade the lithosphere, ... -
Missing so<sub>2</sub> oxidant in the coastal atmosphere? – observations from high-resolution measurements of oh and atmospheric sulfur compounds
(Copernicus GmbH, 2014-11-20)Diurnal and seasonal variations of gaseous sulfuric acid (H2SO4) and methane sulfonic acid (MSA) were measured in NE Atlantic air at the Mace Head atmospheric research station during the years 2010 and 2011. The measurements ... -
Observations indicative of rain-induced double diffusion in the ocean surface boundary layer
(Wiley-Blackwell, 2015-05-19)Double diffusion can result in the formation of thermohaline staircases, typically observed in the ocean interior. The observations presented here were acquired in the ocean surface boundary layer with the autonomous ... -
Prey preferences of sympatric fin (balaenoptera physalus) and humpback (megaptera novaeangliae) whales revealed by stable isotope mixing models
(Wiley-Blackwell, 2013-04-25)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 ... -
Satellite and in situ salinity: understanding near-surface stratification and subfootprint variability
(American Meteorological Society, 2016-08-01)Remote sensing of salinity using satellite-mounted microwave radiometers provides new perspectives for studying ocean dynamics and the global hydrological cycle. Calibration and validation of these measurements is challenging ... -
Signals from the deep: spatial and temporal acoustic occurrence of beaked whales off western ireland
(Public Library of Science (PLoS), 2018-06-21)Little is known of the spatio-temporal occurrence of beaked whales off western Ireland, limiting the ability of Regulators to implement appropriate management and conservation measures. To address this knowledge gap, static ... -
Stable isotope analysis of baleen reveals resource partitioning among sympatric rorquals and population structure in fin whales
(Inter-Research Science Center, 2013-04-08)Stable isotope analysis is a useful tool for investigating diet, migrations and niche in ecological communities by tracing energy through food-webs. In this study, the stable isotopic composition of carbon and nitrogen in ... -
