Mapping Scytonemin Pigment Content and Biocrust Functional Indicators Using High‐Resolution Multispectral Imagery

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
We demonstrate that high‐resolution multispectral imagery combined with machine learning can accurately predict key biocrust functional indicators, particularly the UV‐protective pigment scytonemin, across dryland ecosystems. Using fine‐scale imagery acquired in the Chihuahuan Desert and Colorado Plateau, we identified spectral bands strongly ...

Platinum Group Element Traces of CAMP Volcanism Associated With Low‐Latitude Environmental and Biological Disruptions

open access: yesGeophysical Monograph Series, Page 263-304., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Snow-Water Equivalent Observation by Pressure Pillow

open access: yesJournal of the Japanese Society of Snow and Ice, 1977
During the period from 26 November 1976 to 10 May 1977, a continuous observation of snow-water equivalent by the use of surface-mounted type pressure pillow 2. 4 m in diameter, mounted on ground surface. was carried out at Hassaki, Yunotani-mura, Kitauonuma-gun, Niigata-ken, Japan.The inner pressure of this pillow was measured electrically by a ...

A Dual‐Mode Photoconductive Colorimetric Wearable UV‐Dosimeter: Strategies for Tunable UV‐Band Sensitivity

open access: yesSmall, EarlyView.
The harmful ultraviolet component of sunlight necessitates reliable and wavelength‐selective personal UV monitoring technologies. Here, thermally evaporated CuBr thin films enable dual‐mode UV dosimetry through persistent photoconductive and colorimetric responses arising from charge trapping and surface oxide formation.

Estimating Daily Snow Density Through a Spatiotemporal Random Forest Model

open access: yesWater Resources Research
Snow density is of paramount importance in water resource management, snow avalanche warning, and climate change research. However, the lack of competent methods for long‐term and vast‐scale snow density mapping persists due to the intricate ...

Emergent Innovation in Systemic Programme Design: Retrospective Reflections on the Development of a Student‐Centred Masters in Systems Thinking

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT Our theory of education, based on a systemic understanding of the subjective and intersubjective construction of knowledge, is that students are motivated to study what is most meaningful to them. Meaningfulness is grounded in the students' prior experiences, which are highly diverse.

The “We” and “Me” of Identity in Hazardous Industry Organizations: Face Work Tactics Among Practicing Engineers

open access: yesSymbolic Interaction, EarlyView.
In this paper, we use Goffman's notion of “face work” to examine how pipeline engineers perform and present their working selves as competent experts. Our analysis identifies various faces and face work tactics, including a focus on professional judgment, actively selling one's expertise relative to others, protective self‐deprecatory strategies, and ...

On the Measured Values of Water Equivalent of Deposited Snow

open access: yesJournal of the Japanese Society of Snow and Ice, 1956
In this report are shown results of some experiments concerning the error of value of water equivalent of the deposited snow by snow sampler on the level land.From author's experiments, it seems that the measured values of water equivalent of the deposited snow vary considerably due to the difference of time, places and diameter size of the sampler ...

Unusual vertical oscillations of a radiosonde

open access: yesWeather, EarlyView.
In summer 2023 in southern England, several unusual balloon launches were observed which descended for a few minutes before resuming ascent. This unusual vertical oscillation was repeated several times in a ‘roller‐coaster’‐like pattern. This article discusses the behaviour of the balloons.
