Human activities in the deep North Atlantic

, 2011
To achieve long-term planning and whole-ecosystem management of the oceans requires data on the extent of human impacts and the wider availability of data on human activities. This study, which aimed to provide the first detailed assessment of the extent

North American “warming holes” and European heat during abrupt Holocene cooling events in the Atlantic

Nature Communications
In recent decades, Europe has warmed rapidly while a prominent ‘warming hole’ has muted changes in eastern North America. Paradoxically, the pattern coincides with cooling in the North Atlantic, even though ocean cooling is commonly expected to chill ...

The influence of solar activity on action centres of atmospheric circulation in North Atlantic [PDF]

Annales Geophysicae, 2015
We analyse the response of sea level pressure and mid-tropospheric (500 hPa) geopotential heights to variations in solar activity. We concentrate on the Northern Hemisphere and North Atlantic in the period 1948–2012. Composite and correlation analyses

Intermediate and deep water paleoceanography of the northern North Atlantic over the past 21,000 years [PDF]

Benthic foraminiferal stable isotope records from four high-resolution sediment cores, forming a depth transect between 1237 m and 2303 m on the South Iceland Rise, have been used to reconstruct intermediate and deep water paleoceanographic changes in ...

The musculature and skeleton of the pelvic fin of the crocodile shark, Pseudocarcharias kamoharai (Matsubara, 1936) (Elasmobranchii: Lamniformes): Morphology and sexual dimorphism

The Anatomical Record, EarlyView.
This work brings new information on the sexual characteristics of the crocodile shark (Pseudocarcharias kamoharai) exploring the pelvic fin musculature, as well as the siphon sac and the musculature and skeleton of the clasper. Our paper is the first to point out clearly the sexual dimorphism related exclusively to the pelvic fin musculature in males ...

A seasonal diary of phytoplankton in the North Atlantic [PDF]

, 2014
In recent years new biological and physical controls have been suggested to drive phytoplankton bloom dynamics in the North Atlantic. A better understanding of the mechanisms driving primary production has potentially important implications for the ...

Postnatal craniomandibular growth in Harbor seals (Phoca vitulina vitulina)

The Anatomical Record, EarlyView.
Postnatal ontogeny in Harbor seals (Phoca vitulina vitulina). Cranium and mandible grow rapidly until 5 years of age, followed by a deceleration and finally a stagnation. Abstract As secondarily aquatic carnivores, seals display several phenotypic differences compared to their terrestrial relatives.

Tropical Atlantic rainfall drives bias in extratropical seasonal forecasts

Atmospheric Science Letters
We investigate the impact of seasonal forecast biases in the Tropical Atlantic on the North Atlantic. The analysis uses a novel ensemble‐based method to estimate the impact of tropical rainfall bias on forecasts of the Extratropical North Atlantic.

Temporal variations in English Populations of a forest insect pest, the green spruce aphid (Elatobium abietinum), associated with the North Atlantic Oscillation and global warming [PDF]

, 2007
Based on an exceptionally long modern ecological dataset (41 years), it has been possible to show that warm weather in England associated with a positive North Atlantic Oscillation (NAO) index causes the spring migration of the green spruce aphid ...
