A GIS based study on bank erosion by the river Brahmaputra around Kaziranga National Park, Assam, India

Kaziranga National Park — 2012 — WHE8A5E183516

Kaziranga National Park, home to the world's largest population of one-horned rhinoceroses and a rich biodiversity, has experienced significant land loss due to bank erosion by the Brahmaputra River. A GIS-based study revealed that from 1912–1916 to 2008, the park lost 88.188 km² of area, with erosion outpacing sediment deposition in all studied periods (1912–1972, 1972–1998, and 1998–2008). The highest erosion rates were observed between 1972 and 1998 (1.59 km²/year), while the maximum bankline shifts reached 4.58 km during 1912–1972. Loose, non-cohesive sediments along the riverbanks, combined with the river's braided course, were identified as primary causes of erosion. The study suggests future deposition may increase in the park's eastern part, while middle regions face continued erosion risk. Antierosion measures have been implemented only sporadically.

A model for uranium mobility in groundwater in the Grand Pré region, Nova Scotia, Canada

Landscape of Grand Pré — 2012 — WHE89C0CA89C6

A recent study reveals that uranium mobility in groundwater within the Grand Pré region, Nova Scotia, is strongly influenced by redox conditions and regional geology. The research found that while reduced groundwater in Horton Bluff sandstone typically contains elevated levels of iron (Fe²⁺) and manganese (Mn²⁺), high concentrations of uranium are predominantly present in oxidizing environments within the Wolfville Formation's quartz arenite sandstone units. This suggests a complex interplay between lithology and redox conditions, with aesthetically undesirable water (high Fe and Mn) potentially posing less health risk than visually appealing water (low Fe and Mn but high U). The study analyzed 72 cations and 9 major anions from well water samples, identifying uranium levels up to 50.8 µg/L, exceeding Health Canada's limits. These findings underscore the need for further assessment of health risks associated with groundwater consumption in the region.

A monument of early Byzantine Sardis: architectural analysis and graphic reconstruction of Building D

A major architectural reconstruction of Building D, an enigmatic early Byzantine monument at Sardis, reveals its original form and function, providing unprecedented insights into the development of late antique architecture in western Asia Minor. The study demonstrates that despite its dilapidated state, careful analysis of the building's fabric—including a reused fourth-century inscription and construction details—enables the identification of its primary load-bearing elements and an enormous vaulted canopy. This reconstruction not only sheds light on the role of Building D in the urban landscape of Sardis but also contributes to understanding the evolution of early Byzantine monumental architecture during a pivotal period of Christianization and urban transformation (4th–6th centuries AD).

A multi-sensor polarimetric analysis over archaeological sites

Samarra Archaeological City — 2012 — WHE456BD88E7C

Polarimetric synthetic aperture radar (SAR) analysis reveals distinct configurations for optimal detection of archaeological structures. Comparing RADARSAT-2 and ALOS-PALSAR data at similar incidence angles (23.10°, 26.20°, and 27.07°), researchers identified that varying RADARSAT-2 incidence angles (27° vs. 45°) significantly enhances subsurface feature visibility in UNESCO-listed Samarra, Iraq, and Gebel Barkal, Sudan. This multi-sensor approach demonstrates that adjusting radar incidence angle can improve the identification of buried structures, offering a non-invasive method for archaeological mapping.

A new karyotype for the spiny rat Clyomys laticeps (Thomas, 1909) (Rodentia, Echimyidae) from Central Brazil

Cerrado Protected Areas: Chapada dos Veadeiros and Emas National Parks — 2012 — WHEA8E383AC4F

Researchers have uncovered a new karyotype for the spiny rat, Clyomys laticeps, a semifossorial rodent endemic to the tropical savannas and grasslands of central Brazil. Analyzing four specimens from Emas National Park in Goiás, Brazil, the study revealed a diploid number (2n) of 32 chromosomes and a fundamental autosome number (FN) of 54. The karyotype features 12 meta/submetacentric pairs and three acrocentric pairs, with the X chromosome being medium submetacentric and the Y chromosome medium acrocentric. Cytogenetic techniques such as conventional staining, CBG, and GTG-banding were employed to characterize these chromosomal structures. The findings suggest that the semifossorial habits and habitat specificity of this genus may contribute to observed karyological variations.

A New Phase of the Temple of Preah Vihear Dispute before the International Court of Justice: Reflections on the Indication of Provisional Measures of 18 July 2011

Temple of Preah Vihear — 2012 — WHE839C895A9E

A significant legal milestone was reached on 18 July 2011, when the International Court of Justice (ICJ) issued provisional measures regarding the Temple of Preah Vihear dispute between Cambodia and Thailand.
