Particle Fluxes in the North-East Atlantic and Southern Ocean
… buoyant sediment trap (PELAGRA). In the north-east Atlantic<br/>organic carbon fluxes were measured using this new technology and compared to indirect<br/>estimates of export based on 234Th and nutrient budgets. The vertical fluxes of 234Th into the<br/>traps were less than those …

Spatial modelling of blue whiting population dynamics in the north-east Atlantic
… blue whiting, Micromesistius poutassou, in the North-East Atlantic has been developed. Since stock biomass fluctuations recorded in the past decades have raised concerns for the stock sustainability, improving our understanding of blue whiting population dynamics has become necessary for …

Determination of Dissolved Iron Speciation in the North East Atlantic Ocean by Flow Injection Chemiluminescence
… (< 0.2 µm) in two contrasting study areas in the North East Atlantic Ocean and for a study of aerosol iron dissolution in seawater. The FI-CL method was evaluated and was found to be robust and sensitive, to have low limits o f detection (5-12 pM) and short analysis times 3 min) suitable for the …

Microplastic pollution in the deep sea ecosystem: a study from the Rockall Trough, North East Atlantic Ocean
… site located >2000 m deep in the Rockall Trough, North East Atlantic Ocean. The hypothesis that microplastics are present within this ecosystem is tested and their historical occurrence over different time-scales is investigated. Potential sources of the microplastics and their distribution …

Observations of oceanic potential vorticity and its relationship with other tracers
… investigated. The regions studied were in the North-east Atlantic, the Sargasso Sea and the Bellingshausen Sea (Southern Ocean).The only earlier work known in this field was by Fischer et al. (1989), which found a near-linear relationship between PV and isopycnic potential temperature on a …

Human activities in the deep North Atlantic
… of the extent of human activities in the deep North East Atlantic, OSPAR Maritime Area, revealed that during 2005 bottom-trawl fisheries affected an area of seafloor at least one order of magnitude greater than all the other the activities in the study combined. It was also found that …

Scotland’s blue carbon: the contribution from seaweed detritus
… taken in Scottish fjords and in areas of the North-East Atlantic shelf. The presence of macroalgae DNA also correlated with presence of polyphenols, strongly suggesting compounds from macroalgae accumulate in sediments. Macroalgae DNA was also found in sediment cores up to 60 cm deep, which …

Effects of hematodinium infection on the Norway lobster, nephrops norvegicus (L.)
… of the most valuable shellfish resources in the north east Atlantic ocean and considerable knowledge exists with regard to its biology and life history. During the late 1980s, populations of N. norvegicus were shown to harbour an infection by a parasite of the genus Hematodinium (Dinoflagellata: …
