Subjects: Environmental Studies, Hydrology, Other Geography

Groundwater depletion, contamination, and governance challenges persist despite decades of groundwater research. Scientific methods are crucial yet seem insufficient to inspire the deep emotional and cultural connections needed for real change – groundwater challenges and opportunities are not reaching enough hearts and minds. This article calls for a bold shift: integrating arts-based research [...]

Doing conferences differently: a decentralised multi-hub approach for ecological and social sustainability

Alexandra Corneyllie, Trudie Walters, Anne Sophie Dubarry, et al.

Published: 2024-12-11
Subjects: Environmental Studies

Conferences are invaluable for career progression, offering unique opportunities for networking, collaboration, and learning. However, there are challenges associated with the traditional in-person conference format. For example, there is a significant ecological impact from attendees’ travel behaviour, and there are social inequities in conference attendance, with historically marginalised [...]

Evaluation and prediction of the Effects of Planetary Orbital Variations to Earth’s Temperature Changes

Mengmeng Cao, Kebiao Mao, Sayed M. Bateni, et al.

Published: 2024-12-11
Subjects: Education, Engineering, Physical Sciences and Mathematics

Existing climate studies mainly assessed the effect of greenhouse gases and aerosols, among other forcings on Earth’s temperature. None of them has not evaluated the effect of the planetary orbital changes on Earth’s temperature. Here, we deconvolved the effects of greenhouse gases and planetary orbital changes on Earth’s temperature and to forecast the latter at different time scales. Our [...]

Demise of the Barra Honda carbonate shoal (Costa Rica) at the Paleocene-Eocene boundary linked to climate change and forearc tectonics

Goran Andjić, Claudia Baumgartner-Mora, Peter Oliver Baumgartner, et al.

Published: 2024-12-11
Subjects: Physical Sciences and Mathematics

The latest Cretaceous(?)–Paleocene Barra Honda Formation represents one of the largest carbonate shoals (>900 km2, 350 m thick) of the convergent margin of Costa Rica. Although the mode of formation of the carbonate shoal is well understood, how environmental and tectonic factors interacted to cause its demise near the Paleocene-Eocene boundary remains poorly constrained. Stable isotopic, [...]

Joint effects of submesoscale lateral dispersion and biological reactions on biogeochemical flux

Lulabel Ruiz Seitz, Mara Freilich

Published: 2024-12-11
Subjects: Applied Mathematics, Oceanography, Oceanography and Atmospheric Sciences and Meteorology, Physical Sciences and Mathematics

Submesoscale dynamics, operating at spatial scales of O(1−10 km) and temporal scales of O(1 day), are particularly important for marine ecosystems as they occur on similar timescales as phytoplankton growth, enabling biophysical feedbacks. While submesoscale dynamics are known to impact biological fluxes by modifying nutrient upwelling, horizontal transport has traditionally been assumed to only [...]

Climate-Induced Sea-Level Rise Implications on Archaeological Taonga at Te Pokohiwi ō Kupe – The Wairau Bar, Aotearoa New Zealand

Subjects: Earth Sciences, Environmental Sciences, Oceanography and Atmospheric Sciences and Meteorology

The northwest portion of Te Pokohiwi ō Kupe (the Wairau Bar) in the Marlborough Region is where one of Aotearoa New Zealand’s earliest archaeological heritage sites dating back to the early 1300’s is located. This paper describes a baseline study to map the effects of present-day and future sea-levels on archaeological heritage land at Te Pokohiwi ō Kupe. Results suggest that approximately 20% of [...]

Small pluton construction through sills stacking, amalgamation and differentiation: Insight from the Beauvoir granite (Massif Central, France)

Nicolas Esteves, Lydéric France, Michel Cuney, et al.

Published: 2024-12-11
Subjects: Earth Sciences

The kinematics, modes of assembly, and the processes governing the evolution of magmas shape plutonic intrusions. Granite bodies have been suggested to emplace incrementally, with successive magmatic batches locally solidified as dikes or sills. Yet, the complexity and longevity of large-scale plutons hinders a unified model for their emplacement and concomitant differentiation. This is [...]

Systemic impacts of low-carbon transition policies for housing in Innsbruck: Mapping the intersections of vulnerability and social justice with affected citizens and stakeholders

Michael Klingler, Fiona Lilith Medea de Fontana, Daniel Gerdes, et al.

Published: 2024-12-11
Subjects: Human Geography

Decarbonizing the building sector is a key priority in the European energy transition, as it is responsible for more than a third of the EU's GHG emissions. To boost energy renovation rates and efforts to phase out fossil fuel-based heating systems, current energy policy directives tar-get in particular the promotion of energy efficiency. However, implementing technology-oriented solutions for [...]

Functional regression for space-time prediction of precipitation-induced shallow landslides in South Tyrol, Italy

Mateo Moreno, Luigi Lombardo, Stefan Steger, et al.

Published: 2024-12-10
Subjects: Applied Statistics, Environmental Indicators and Impact Assessment, Environmental Monitoring, Geology, Geomorphology, Hydrology, Multivariate Analysis, Statistical Models

Shallow landslides are geomorphic hazards in mountainous terrains across the globe. Their occurrence can be attributed to the interplay of static and dynamic landslide controls. In previous studies, data-driven approaches have been employed to model shallow landslides on a regional scale, focusing on analyzing the spatial aspects and time-varying conditions separately. Still, the joint assessment [...]

Disappearance of Homo floresiensis from Liang Bua alongside seasonal aridification of Flores 61,000-47,000 years ago

The cause of the disappearance of the primitive hominin, Homo floresiensis, from the Indonesian island of Flores ~50,000 years ago is a key question in palaeoanthropology. The potential roles of human agency and climate change continue to be debated, but the history of freshwater availability critical to survival at the type locality, Liang Bua, remains unknown. Although speleothem 18O is used [...]

Challenging the turbidity current maximum run-up height paradigm

Ru Wang, Mia Hughes, David Hodgson, et al.

Published: 2024-12-09
Subjects: Earth Sciences, Fluid Dynamics, Geology, Sedimentology, Stratigraphy

Turbidity currents are a primary mechanism for transporting sediments, pollutants, and organic carbon into the deep ocean. They are strongly influenced by seafloor topography because of their relative bulk density and associated gravitational influence being 3-4 orders of magnitude smaller than in terrestrial systems. Marked run-up of turbidity currents on slopes poses a hazard to seafloor [...]
