Endocranial anatomy of the earliest Cretaceous European neosuchian crocodyliform Pholidosaurus purbeckensis provides new evidence for the ecological evolution of Pholidosauridae

open access: yesJournal of Anatomy, EarlyView.
We present new insights into the internal cranial anatomy of the neosuchian crocodyliform Pholidosaurus purbeckensis, based on CT‐scan data of material from the lowermost Cretaceous Purbeck Limestone Group, southern UK. From the study of the endocast, we obtained new information on the phylogeny and the ecological evolution of the Family ...

Understanding marine biodiversity patterns and drivers: The fall of Icarus

open access: yesMarine Ecology, EarlyView.
Abstract Biodiversity patterns are fundamental in our understanding of the distribution of life, ecosystem function, and conservation. In this concept analysis, A survey of the existing knowledge on marine biodiversity patterns and drivers across latitudes, longitudes, and depths indicates that none of the postulated patterns represent a rule.

Modelling the controls on melt generation during continental extension and breakup

open access: yes, 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.

Numerical Simulation of Precipitation Induced by Hot Mid-Ocean Ridges

open access: yes, 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.

Earthquake and volcanic processes at mid-ocean ridges

open access: yes, 2019
In this thesis, I present results that broadly fall into two themes. The first involves understanding active tectonic and magmatic processes at mid-ocean ridges.

That sinkin’ feeling: Environmentally induced distress on a disappearing island

open access: yesMedical Anthropology Quarterly, EarlyView.
Abstract Residents of Tangier Island, Virginia, a subsiding island in the Chesapeake Bay, embody psychosocial dimensions of environmental change. Analysis of ethnographic data shows islanders’ experiences and articulations of anxiety, panic, and despair as “that sinkin’ feeling,” resulting from the stress of living with the long‐term threat of imminent

Effects of variable magma supply on mid‐ocean ridge eruptions: Constraints from mapped lava flow fields along the Galápagos Spreading Center

open access: yesGeochemistry, Geophysics, Geosystems, 2012
Mapping and sampling of 18 eruptive units in two study areas along the Galápagos Spreading Center (GSC) provide insight into how magma supply affects mid‐ocean ridge (MOR) volcanic eruptions. The two study areas have similar spreading rates (53 versus 55

Specialized Committees of International Organizations an Important Source of Organizational Autonomy

open access: yesRegulation &Governance, EarlyView.
ABSTRACT Assigning the preparation of decisions to specialized committees composed of member state representatives is a widespread response to the ‘governor's dilemma’, that is, the tension between competence and control, in international organizations (IOs). We theorize a causal mechanism referring to self‐selection and agenda‐setting effects and show

The Role of Peridotite for Oceanic Volcanism

open access: yesGeochemistry, Geophysics, Geosystems
The complementary products of oceanic crust formation are compositionally variable melt‐depleted peridotites. Together with the oceanic crust, the melt‐depleted peridotites are continuously recycled back into the mantle.

Quantifying melt production and degassing rate at mid‐ocean ridges from global mantle convection models with plate motion history

open access: yes, 2018
The Earth's surface volcanism exerts first‐order controls on the composition of the atmosphere and the climate. On Earth, the majority of surface volcanism occurs at mid‐ocean ridges. In this study, based on the dependence of melt fraction on temperature,
