Topology‐based Visual Analysis of Hydrothermal Plumes

open access: yesComputer Graphics Forum, EarlyView.
Abstract Hydrothermal plumes are turbulent structures of intense heat and mineral smoke that rise and disperse into the deep ocean. Existing models generally characterize these systems as a single axisymmetric plume originating from a point source. However, this assumption breaks down in weakly venting, spatially distributed systems, where low‐flux ...

On the Role of Climate Forcing by Volcanic Sulphate and Volcanic Ash [PDF]

open access: yesAdvances in Meteorology, 2014
There is overall agreement that volcanic sulphate aerosols in the stratosphere can reduce solar radiation reaching the earth’s surface for years, thereby reducing surface temperatures, affecting global circulation patterns and generally the global climate system.

Electric charge within volcanic plumes on Earth and Io [PDF]

open access: yes, 1998
Field, experimental and theoretical investigations have been carried out into the electrification of volcanic plumes. At Sakurajima volcano, Japan, ground-level perturbations of the atmospheric electric potential gradient generated by particulate plumes ...

Exploring the Potential of “La Scienza Nell'arte” as an Approach to Science Through Art

open access: yesCurator: The Museum Journal, EarlyView.
ABSTRACT European policies and academic research are striving to bridge the gap between the humanities and sciences as interconnected fields. This paper analyses how science can be approached through art by exploring the Italian “La scienza nell'arte” initiative.

Volcanic ash beds in the Waikato district

open access: yes, 1967
This report lies somewhere between the "pathfinder" variety and the completed account for the reason that the results of detailed mapping and identification are still being prepared for publication. For the younger beds less than 36,000 years we now know

Interstitial 11q Deletions and Terminal 11q Duplications Cause a Bleeding Tendency due to Platelet Dysfunction That Is Similar to 11q Deletions Causing Jacobsen Syndrome

open access: yesEuropean Journal of Haematology, EarlyView.
ABSTRACT Introduction Jacobsen syndrome, resulting from a terminal deletion of chromosome 11 (11q), may lead to an increased bleeding tendency due to low platelet counts or platelet dysfunction. Currently, information on bleeding tendency and platelet function in patients with nonterminal 11q‐aberrations such as larger deletions, interstitial 11q ...

An investigation of changes to commercial aircraft flight paths during volcanic eruptions

open access: yesJournal of Applied Volcanology
Volcanic eruptions can inject ash into the atmosphere, which is then advected by meteorological winds, potentially affecting large volumes of airspace. Volcanic Ash Advisory Centres (VAACs) issue volcanic ash advisories (VAAs) when airspace is likely to ...

Contorted stratification with clay lobes in volcanic ash beds, Raglan-Hamilton region, New Zealand

open access: yes, 1970
Contorted stratification in basal volcanic ash beds of the Pleistocene Hamilton Ash Formation incorporates halloysitic clay lobes which project upward into a bed of predominantly allophanic material.

The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman

open access: yesJournal of Petroleum Geology, EarlyView.
ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.
