Ionosphere‐Thermosphere Coupling in the Northern Polar Region During the May 2024 Geomagnetic Superstorm

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract The May 2024 superstorm, as the most intense geomagnetic storm since 2003, caused a variety of disturbances in the magnetosphere‐ionosphere‐thermosphere system. This study investigates the long‐lasting electron density depletion in the polar region and the underlying ionosphere‐thermosphere coupling, based on a comprehensive set of ...

Persistent Ocean‐Shelf Transport Across the North West European Shelf Edge

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract Transport mechanisms between the deep ocean and adjacent continental shelf seas play an important role in the spatial distribution of nutrient delivery to the coastal ocean and in the temporal variability of shelf biogeochemical processes. Along the North West European Shelf (NWES) edge, nutrient‐rich waters of oceanic origin are found below ...

Detrital Zircon Data Support Stronger, Inland‐Tracking Hurricanes During the Miocene Climatic Optimum, Maryland USA

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 2, February 2026.
Abstract Climate models run under warmer‐than‐modern conditions indicate that hurricanes pass closer to the US East Coast and show that a higher proportion of tropical cyclones achieve “major hurricane” strength with winds >209 km/hr. Empirical observations indicate that the dominant southward longshore current direction off the US East Coast is ...

The NextGen Water Resources Modeling Framework: Community Innovation at the Intersection of Hydrologic, Data and Computer Sciences

open access: yesJAWRA Journal of the American Water Resources Association, Volume 62, Issue 1, February 2026.
ABSTRACT Hydrologic science lacks a comprehensive theory of stormflow generation, preventing the development of a general hydrologic model. Studies show that models focusing on dominant local processes often outperform general models that rely on parameter tuning, leading to higher confidence solutions.

Waves Under Control? A Meta‐Analysis of Morphological Restoration as a Strategy to Mitigate Navigation‐Induced Disturbances

open access: yesFreshwater Biology, Volume 71, Issue 2, February 2026.
ABSTRACT Ship‐induced waves significantly impact freshwater ecosystems, estuaries and tidal rivers by accelerating shoreline erosion and reducing aquatic biodiversity. Morphological protection measures are implemented to mitigate these adverse effects, but their effectiveness in preventing shoreline zone deterioration has not been systematically ...

Sampling the volcanic plumes at Io: Impact speeds and shock conditions

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 2, Page 241-271, February 2026.
Abstract The desire to sample material from the interior of Io, by flying through its volcanic plumes, requires consideration of the flyby speed and the types of sample collection techniques that can be utilized. Low speed collection (1–2.5 km s−1) would require an orbit around Io itself, which is unlikely due to the accumulated radiation dose that ...

Sustainability and Its Seven Sisters

open access: yesNatural Resource Modeling, Volume 39, Issue 1, February 2026.
ABSTRACT There are many concepts of sustainability. Robert Solow argued that sustainability would consist of conserving human well‐being over the “very long run”, through the interactions of the environment and other stocks in human decisions and activity.

The regional evolution of a dryland fluvio‐aeolian and lacustrine succession in response to allocyclic forcing: insights from the Early Permian Cutler Group, Utah, USA

open access: yesSedimentology, Volume 73, Issue 2, Page 297-354, February 2026.
ABSTRACT Preserved allocyclic signatures in the rock record often reflect basin‐scale climatic variability and serve as key proxies for correlating ancient dryland successions. The notion of climate cyclicity, however, remains largely untested on regionally constrained, outcrop‐calibrated studies.

How natural are the sediments on our beaches? Characterising urban anthropogenic mixed beaches in Scotland

open access: yesSedimentology, Volume 73, Issue 2, Page 519-539, February 2026.
ABSTRACT Mixed beaches containing anthropogenic geomaterials such as bricks, concrete, glass, ceramics, tarmac and slag are globally understudied. These materials enter natural beach systems through erosion or dumping, and rising sea levels and increased storminess are expected to intensify coastal erosion, reworking and re‐exposing previously dumped ...

Levelised cost of energy site selection tool for tidal stream energy devices

open access: yes, 2021
In order for the tidal stream energy sector to achieve commercial maturity, procedural improvements must be made in order to increase economic viability. This thesis targets the site selection procedure specifically. The aim is to improve the established method of site selection and increase the capability of this project phase, by demonstrating the
