Morphology and tectonics of the Mid-Atlantic Ridge, 7°–12°S

, 2003
We present swath bathymetric, gravity, and magnetic data from the Mid-Atlantic Ridge between the Ascension and the Bode Verde fracture zones, where significant ridge–hot spot interaction has been inferred.

Insights into mantle composition and mantle melting beneath mid-ocean ridges from postspreading volcanism on the fossil Galapagos Rise [PDF]

, 2011
New major and trace element and Sr, Nd, and Pb isotope data, together with 39Ar-40Ar ages for lavas from the extinct Galapagos Rise spreading center in the eastern Pacific reveal the evolution in magma compositions erupted during slowdown and after the ...

A new species of Lonchidiidae (Hybodontiformes) from the Late Jurassic of Brazil (Aliança Formation, Jatobá Basin)

The Anatomical Record, EarlyView.
Abstract The Aliança Formation (Jatobá Basin) represents lacustrine deposits formed in oxygenated waters that hosted a diverse fauna, including Hybodontiform sharks. Within this group, the Family Lonchidiidae comprises 11 valid genera, with Parvodus previously reported in Brazilian deposits from the Brejo Santo Formation (Araripe Basin, Late Jurassic ...

Gleaning the Rocky Shore? 2500 Years of Coastal Resource Use at Red Bluff 1, GunaiKurnai Country, SE Australia

Archaeology in Oceania, EarlyView.
ABSTRACT Shell middens in Gippsland along the eastern half of Victoria's coastline have usually been characterised as small, short‐duration camp sites with relatively low shell densities and low taxonomic diversity. Here we present new excavation results from a dense, high‐diversity site at Red Bluff near the eastern end of GunaiKurnai Country, a ...

Geodynamic Models of Melt Generation and Extraction at Mid-Ocean Ridges [PDF]

Oceanography, 2012
It is widely accepted that plate divergence at mid-ocean ridges drives mantle flow, mantle melting, and the formation of new oceanic crust. However, many of the details of this process remain obscure because of the inaccessibility of the mantle to direct

Chemical Heterogeneities along the South Atlantic Mid-Ocean-Ridge (5-11°S): Shallow or Deep Recycling of Ocean Crust? [PDF]

, 2011
Between 5° and 11°S, the Mid-Atlantic Ridge displays anomalous crustal thickness and geochemical compositions, thought to be related to either small scale upper mantle heterogeneities or a weak, diffuse mantle plume.

Injuries in deep time: interpreting competitive behaviours in extinct reptiles via palaeopathology

Biological Reviews, EarlyView.
ABSTRACT For over a century, palaeopathology has been used as a tool for understanding evolution, disease in past communities and populations, and to interpret behaviour of extinct taxa. Physical traumas in particular have frequently been the justification for interpretations about aggressive and even competitive behaviours in extinct taxa.

Changes in water mass composition and circulation in the central Arctic Ocean between 2011 and 2021 inferred from tracer observations [PDF]

Ocean Science
The Arctic Ocean is changing rapidly and Atlantic Water circulation plays a key role in the warming, sea-ice decline, and ecosystem changes observed in the Arctic.
