The Material Basis of 18th‐Century Meissen Porcelain
Archaeometry, EarlyView.ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.

Genetic and Ecological Management of Pacific Salmon Fisheries for the 21st Century
Fisheries Management and Ecology, EarlyView.ABSTRACT Based on ecological adaptation theory, tremendous effort is being spent on measures that are eliminating salmon hatcheries and fishing opportunities with the intention of protecting wild runs deemed to be of particular genetic importance to the survival of the species.

Earth, Planets and Space, 2018 A pyroclastic density current (PDC) was observed with the phreatomagmatic eruption of the Kuchinoerabujima volcano, southern Japan, on May 29, 2015. The PDC flowed down in all direction from the source crater, forming three major branches.

Sedimentology, EarlyView.ABSTRACT Subaerial Pyroclastic Density Currents (PDCs) and Subaqueous Eruption‐Fed Density Currents (SEFDCs) produced during volcanic eruptions can present major hazards to surrounding communities and ecosystems. The bedforms deposited by these volcanic density currents can provide insights into the nature of transport and depositional processes, which

Paleointensity Estimates From Ignimbrites: The Bishop Tuff Revisited
Geochemistry, Geophysics, Geosystems, 2018 Volcanic ash flow tuffs (ignimbrites) may contain single domain‐sized (titano) magnetite that should be good for recording geomagnetic field intensity, but due to their complex thermal histories also contain other magnetic grains, which can complicate ...

Temperatures of the A.D. 79 pyroclastic density current deposits (Vesuvius, Italy) [PDF]
Journal of Geophysical Research: Solid Earth, 2004 The temperature of the deposits left by different types of pyroclastic density currents (PDCs) of the A.D. 79 “Pompei” eruption of Vesuvius was estimated by measuring the thermal remanent magnetization (TRM) of lithic clasts carried by the currents. More than 200 lava clasts and roof tile fragments were collected at different sites and distances from ...

A Combined Field and Numerical Approach to Understanding Dilute Pyroclastic Density Current Dynamics and Hazard Potential: Auckland Volcanic Field, New Zealand [PDF]
, 2014 The most dangerous and deadly hazards associated with phreatomagmatic eruption in the Auckland Volcanic Field (AVF; Auckland, New Zealand) are those related to volcanic base surges - dilute, ground-hugging, particle laden currents with dynamic pressures ...

Infrasound from Volcanic Rockfalls [PDF]
, 2015 Proximal infrasound arrays can robustly track rapidly moving gravity-driven mass wasting, which occurs commonly at erupting volcanoes. This study reports on detection, localization, and quantification of frequent small rockfalls and infrequent ...
