Dam busy: beavers and their influence on the structure and function of river corridor hydrology, geomorphology, biogeochemistry and ecosystems

Annegret Larsen, Stuart N Lane, Joshua R Larsen

Published: 2020-10-22
Subjects: Education

Beavers (castor fiber, castor canadensis) are the most influential mammalian ecosystem engineer, heavily modifying river corridors and influencing hydrology, geomorphology, nutrient cycling, and ecology. As an agent of disturbance, they achieve this first and foremost through dam construction, which impounds flow and increases the extent of open water, and from which all other landscape and [...]

Published: 2020-07-24
Subjects: Earth Sciences, Education, Physical Sciences and Mathematics, Volcanology

The Volcanic and Magmatic Studies Group (VMSG) takes equality, diversity and inclusion (EDI) seriously and we recognise that the under-representation and/or unconscious marginalisation of any group impacts on our ability to fulfill our mission to serve the volcanology, petrology and geochemistry community. The following report summarises the findings from both the 2016-2020 VMSG annual meetings [...]

“Enriching Lives within Sedimentary Geology”: Actionable Recommendations for Making SEPM a Diverse, Equitable and Inclusive Society for All Sedimentary Geologists

Innovative science benefits from diversity of thought and influence at all waypoints along the scientific journey, from early education to career-length contributions in research and mentorship. Scientific societies, like the Society for Sedimentary Geology (SEPM), steward their innovators and the direction of the science, thereby defining the societal impact and evolution of a discipline. They [...]

Range-based intensity normalization of ALS data over forested areas using a sensor tracking method from multiple returns

Airborne laser scanning (ALS) point-clouds are used in forest inventory to map properties of the resource. In most cases, only the (x,y,z) coordinates of the point cloud are used to build predictive models of forest structure. Despite being recorded and provided by data suppliers, the intensity values associated with each point are rarely used as an input to such models because raw intensity [...]

Towards local bioeconomy: A stepwise framework for high-resolution spatial quantification of forestry residues

Shivesh Kishore Karan, Lorie Hamelin

Published: 2020-07-08
Subjects: Education, Engineering, Environmental Monitoring, Environmental Sciences, Life Sciences, Natural Resources and Conservation, Other Environmental Sciences, Physical Sciences and Mathematics, Sustainability

In the ambition of a transition from fossil carbon use, forestry residues are attracting considerable attention as a feedstock for the future bioeconomy. However, there is a limited spatially explicit understanding of their availability. Confronted with limited resources for extensive field measurement campaigns, there are also limited discussions on the best practices towards a harmonized [...]

Same but different: A framework to design and compare riverbank plastic monitoring strategies

Subjects: Education, Engineering, Environmental Sciences, Life Sciences, Physical Sciences and Mathematics, Water Resource Management

Plastic pollution in rivers negatively impacts human livelihood and aquatic ecosystems. Monitoring data are crucial for a better understanding of sources, sinks and transport mechanisms of riverine macroplastics. In turn, such understanding is key to develop effective plastic pollution prevention, mitigation and removal strategies. Riverine plastic has been observed in all compartments, of which [...]

Creating Geological Field Trips with the Google Earth Creation Tools

Published: 2020-05-12
Subjects: Earth Sciences, Education, Instructional Media Design, Physical Sciences and Mathematics

Streetcar2Subduction (https://www.agu.org/streetcar2subduction) was launched in December 2019 as a digital update and extension of the timeless 1984 classic field trip guide “Streetcar to Subduction” by Clyde Wahrhaftig . Supported by the American Geophysical Union, we were given early access to the Google Earth Creation Tools in order to build and launch several geology and tectonics field trips [...]

Sedimentary Ripple marks from pavements of forts in Jaipur, Rajasthan. India

Srikanth Guruswamy

Published: 2020-03-18
Subjects: Education, Outdoor Education

Prolific occurrence of a variety of ripple trains in popular forts of Jaipur are observed. The occurrence of extensive Geological sample within man-made buildings form a valuable record for a variety of teaching and research needs. Random samples from these rippled sandstone slabs are classified to highlight their variability. Few standard measures are made on a sample pointing to quantitative [...]

‘Scallywag Bunkers’: Geophysical Investigations of WW2 Auxiliary Unit Operational Bases (OBs) in the UK

In 1940, with the fall of France imminent, Britain prepared for invasion. After Dunkirk, with most armour and transport lost, a defence ‘stop line’ (GHQ Line) was prepared. Local Defence Volunteers (later Home Guard) were raised to buy time for the Home Army to deploy. Secret ‘Auxiliary Units’ were also formed, tasked with ‘Scallywagging’ – guerrilla activities ––in the invading army’s rear. 4-8 [...]

High Attenuation Recycled Materials as landfill liners (the HARM project) – A new concept for improved landfill liner design

A new approach in landfill liner design which combines hydraulic containment of leachate with contaminant attenuation to improve the performance of these environmental control systems at landfills is described. The idea is to re-use readily available industrial waste residues (construction and biomass waste) as additives for natural clay liners, wherein the additives have specific properties [...]

Single-blind test of airplane-based hyperspectral methane detection via controlled releases

Evan David Sherwin, Yuanlei Chen, Arvind P Ravikumar, Adam R. Brandt

Published: 2020-01-08
Subjects: Education, Engineering, Other Engineering

Methane leakage from point sources in the oil and gas industry is a major contributor to global greenhouse gas emissions. The vast majority of such emissions come from a small fraction of "super-emitting" sources which, once detected, can generally be fixed at relatively low cost. We evaluate the emission detection and quantification capabilities of Kairos Aerospace’s airplane-based hyperspectral [...]

Learning by Doing: Enhancing Hydrology Lectures with Individual Fieldwork Projects

Anne Van Loon

Published: 2019-03-19
Subjects: Education, Higher Education, Scholarship of Teaching and Learning

Hydrology teaching deals with processes happening outside the classroom, which calls for active-learning methods to complement lectures. In a geography undergraduate course, new teaching methods and assessment were designed, in which students investigated a river of their choice by completing homework tasks and presenting their results on a poster. During a 3-year implementation process, the [...]

Unfolding Veined Fold Limbs to Deduce a Basins Prefolding Stress State

Koen Van Noten, Manuel Sintubin

Published: 2019-03-06
Subjects: Earth Sciences, Education, Outdoor Education, Physical Sciences and Mathematics, Tectonics and Structure

Tectonic structures that developed prior to folding, such as pre- and early-kinematic veins, hold valuable information on the stress state of the paleobasin in which these early structures formed. To derive the parental orientation of these prefolding brittle structures, folds need to “unfold.” A fold restoration methodology is presented in which fold limbs, and the structures they contain, are [...]
