Barrow, the most northerly community in Alaska, observed a warming of 1.51°C for the time period of 19212012. This represents about twice the global value, and is in agreement with the well-known polar amplification. For the time period of 1979-2012, high quality sea ice data are available, showing a strong decrease in sea ice concentrations of 14% and 16% for the Beaufort and Chukchi Seas, res...

Precise definitions of elliptic islands and chaotic seas are difficult to give. Models for chaotic seas are rare in theory and practice. A few results on the dynamics in the chaotic region are available [1-2-3-4-6-7-9-15-16]. Some topological characterizations of elliptic islands in a chaotic sea are available in [5-8-11-12-17-18-19]. One of the techniques uses rotation numbers [13-14]. There a...

This paper reviews North Atlantic shelf seas palaeoclimate during the interval 4-3Ma, prior to and incorporating the 'Mid-Pliocene warm period' (ca 3.29-2.97Ma). Fossil assemblages and stable isotope data demonstrate northwards extension of subtropical faunas along the coast of the Carolinas-Virginia (Yorktown and Duplin Formations) relative to the present day, suggesting a more vigorous Florid...

[1] Although shelf seas account for only 7% of the oceanic surface area, recent observations demonstrate that they host significant ocean-atmosphere CO2 fluxes. A mechanism implicated in driving a significant CO2 sink in the temperate shelf seas is the Continental Shelf Pump. Here we present an analysis of the impact of sea-level rise, and the consequent flooding of continental shelves, on the ...

Existing methods to predict the effects of climate change on the biomass and production of marine communities are predicated on modelling the interactions and dynamics of individual species, a very challenging approach when interactions and distributions are changing and little is known about the ecological mechanisms driving the responses of many species. An informative parallel approach is to...

The paper presents an investigation of fix-referenced and self-referenced wave energy converters and a comparison of their corresponding wave energy conversion capacities from real seas. For conducting the comparisons, two popular wave energy converters, point absorber and oscillating water column, and their power conversion capacities in the fixed-referenced and self-referenced forms have been...

BACKGROUND Most lung cancers present symptomatically, but the pathway to diagnosis in primary care can be complex and is poorly understood. Significant event audit (SEA) is a quality improvement technique widely used in UK general practice. AIM To gain insights into the diagnostic process for lung cancer, drawn from analysis of SEA documents. DESIGN AND SETTING Qualitative analysis of SEAs...

The practicality of common wave breaking criteria is reviewed. Video recordings of the sea surface taken from aboard R/P FLIP are used to extract breaking wave properties. The key quantity is Λ(c)dc, the length of breaking crests per unit area propagating with speeds in the range (c, c+ dc). Independent of wave field development, Λ(c) is found to peak at intermediate wave scales and to drop off...

Prorocentrum minimum is a potentially harmful and widely distributed marine dinoflagellate. Several P. minimum strains have already been studied, showing phylogenetical relations of strains isolated from the same geographical regions. Similarity among the strains was further examined on the basis of their physiology. Pigment composition and concentration, as well as delayed fluorescence (DF) de...

Reliable forecasts of the timing of sea ice advance are needed in order to reduce risks associated with operating in the Arctic as well as planning of human and environmental emergencies. This study investigates the use of a simple statistical model relating the timing of ice retreat to the timing of ice advance, taking advantage of the inherent predictive power supplied by the seasonal ice-alb...
