Dispersal, source and glass chemistry of a third tephra unit within Iceland's Settlement Layer

open access: yesBoreas, EarlyView.
Tephra layers may be studied to understand the dynamics and sequence of past explosive volcanism. In Iceland, the distinctive Settlement Layer (AD ~877) underlies almost all archaeological evidence for the Norse Settlement and is preserved in soils across Iceland and as cryptotephra overseas.

Abstract Oil and gas producing municipalities host Canada's highest‐emitting industries while facing economic and social risks as the country pursues carbon neutrality. Understanding how these communities envision their economic futures, and the barriers and enablers they encounter in pursuing low‐carbon opportunities, can inform decision‐makers ...

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 ...

Greenhouse gases resulting from grid‐connected electricity demand

open access: yesContemporary Economic Policy, EarlyView.
Abstract Many businesses would like to claim their electricity use results in no greenhouse gases. Because electricity cannot be traced from specific generators to purchasers, regulators and users propose an approximation. Clean electricity use would meet three conditions, or “pillars.” It must be generated (1) nearby, (2) during the same hour, and (3)

Francisella orientalis in Aquacultured Tilapia (Oreochromis spp.): A Case Work‐Up of Diagnostics and Pathologic Findings in the North Central Region (USA)

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Tilapia (Oreochromis spp.) is an increasingly popular aquacultured fish worldwide. While tilapia enjoy a ‘hardy‐fish’ reputation among fish farmers, they are susceptible to a variety of infectious diseases that can be difficult to recognize pondside and have similarities in their gross presentations. This report describes gross and microscopic
