Geophysical characterisation of the ocean–continent transition at magma-poor rifted margins [PDF]

, 2009
Geophysical characterisation of the ocean-continent transition (OCT) at magma-poor riftedmargins has focused primarily on the determination of P wave velocities using wide-angleseismic techniques. Such experiments have shown that the OCT is heterogeneous,

A revised classification system of the marronoid clade of spiders (Araneae), based on dense sampling phylogenomics and comparative morphology

Cladistics, EarlyView.
Abstract The marronoid clade is a globally distributed, ecologically diverse group of spiders. It is an important faunal component in both natural and synanthropic environments, and even found in aquatic and extreme habitats such as desert salt flats. The systematics of the marronoid clade has been notoriously unstable due to the widespread character ...

Modelling the controls on melt generation during continental extension and breakup

, 2008
Rifting is the process that leads to the formation of oceans. Rifting is the break up ofcontinents, leading to the formation of new oceanic floor between the two continentalplates.

An Updated Ecology of Atlantic Salmon (Salmo salar) at Sea

Fisheries Oceanography, EarlyView.
ABSTRACT Atlantic salmon have had a key role in European and North American oceans and human societies. Salmon are exploited and observed in rivers and along coasts, but there has always been great interest in knowing where salmon are going when they are at sea.

Migration of the Antarctic Polar Front through the mid-Pleistocene transition: evidence and climatic implications [PDF]

, 2010
The Antarctic Polar Front is an important biogeochemical divider in the Southern Ocean. Laminated diatom mat deposits record episodes of massive flux of the diatom Thalassiothrix antarctica beneath the Antarctic Polar Front and provide a marker for ...

Seasonal shifts in network structure and species roles in a tropical island plant–flower visitor community Cambios estacionales en la estructura de la red de interacciones entre plantas y visitantes florales y en los roles de las especies en una comunidad insular tropical

Insect Conservation and Diversity, EarlyView.
Constant visitation rates across the flowering season masked major shifts in plant and flower visitor interaction structure, specialization, species roles and trait‐driven patterns shaping interaction intensity. Plants and flower visitors changed ecological roles over time, with native flower visitors playing key roles in maintaining network cohesion ...

Larval Dispersal: Vent Life in the Water Column [PDF]

Oceanography, 2012
Visually striking faunal communities of high abundance and biomass cluster around hydrothermal vents, but these animals don't spend all of their lives on the seafloor.

Volcano-tectonic interactions revealed by inversion of focal mechanisms: stress field insight around and beneath the Vatnajökull ice cap in Iceland

Frontiers in Earth Science, 2014
Volcano-tectonic processes in the central part of Iceland, covered by the Vatnajökull glacier, are investigated by inversion of focal mechanisms. Working on a large catalogue of focal mechanisms determined by the Icelandic Meteorological Office, we used ...

The volcanic history and geochemical evolution of the Hveragerði Region, S. W. Iceland. [PDF]

, 1992
The Hveragerði Region is situated at the Hengill Triple junction, SW Iceland, where there are three volcanic systems. The crust in the area is constructed from both fissure (elongate) and lava shield (conical) eruptive units.

Numerical Simulation of Precipitation Induced by Hot Mid-Ocean Ridges [PDF]

, 2020
A numerical global circulation model developed at the National Center for Atmospheric Research was used to simulate the wind and precipitation patterns caused by a hot sea-surface temperature over the current mid-ocean ridge locations.
