Cretaceous–Palaeogene Plate Boundary Evolution at the Pacific Margins of Zealandia and West Antarctica

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.
Improved satellite‐derived gravity data support updated interpretations and models of ancient plate boundaries and plate motions affecting Zealandia and West Antarctica. The models combine to confidently resolve hundreds of kilometres of Late Cretaceous–Eocene motion between the Pacific and Lord Howe plates, confirming that plate circuit constructions ...

Oil Slick Detection in X-Band Marine Radar Imagery: Leveraging a Boundary-Aware SBR Feature and an Improved Whale Optimization Algorithm

Journal of Marine Science and Engineering
Marine oil spills pose a persistent threat to marine ecosystems and coastal economies, and their rapid and unpredictable spread requires timely and reliable monitoring. In X-band marine radar images, oil slicks usually appear as low-contrast dark targets

Automated Detection of Precipitation induced Artefacts in X-band SAR Images [PDF]

, 2008
Synthetic aperture radar (SAR) images recorded during heavy precipitation events may be severely affected as wavelengths become shorter and acquired SAR images in X - band offer the possibilities to scrutinize the disturbance on SAR images due to weather

Creativity Under Pressure: A Case Study of Drug Cartel Innovation

The Journal of Creative Behavior, Volume 60, Issue 4, December 2026.
ABSTRACT This article examines drug cartels as creative, innovation‐driven organizations rather than solely violent criminal enterprises. Building on creativity research applied to terrorist groups, we use a qualitative case study approach—drawing from news reports, official documents, open‐source materials, and academic work—to analyze 10 cases of ...

Bridging Geomythology and Geospatial Analysis for Flood Risk Assessment in Tamil Nadu

Journal of Flood Risk Management, Volume 19, Issue 4, December 2026.
ABSTRACT The need for more holistic and context‐aware approaches to flood‐risk assessment has become increasingly urgent with extreme climate change events faced globally. Modern models overlook the long‐term environmental knowledge incorporated in ancient literature, myths, and cultural memory as they rely primarily on hydrological and geospatial ...

Ocean surface wind retrieval from stationary and moving platform marine radar data

, 2012
In this paper we evaluate different methods to retrieve wind information from marine radar data. In contrast to traditional in-situ sensors, marine radar wind data cover a large area and therefore are much less susceptible to air flow distortion by the ...

The Stability‐Instability Paradox and the Evolving Balance of Terror in the Middle East

Middle East Policy, Volume 33, Issue 4, Winter 2026.
Abstract In launching its war on Iran, Washington has committed a grave mistake by allowing a weakened Islamic Republic to reconstitute a regional balance of terror. This article shows how the Cold War‐era stability‐instability paradox has been restored in a new form, creating an equilibrium that discourages open warfare while reducing the advantages ...
