Impact hydrodynamique de la mise en place d’un parc d’hydroliennes en Baie du Mont Saint-Michel

Mont-Saint-Michel and its Bay — 2012 — WHED825F9E17C

A study assessing the hydrodynamic impact of deploying tidal turbines (hydroliennes) in the Bay of Mont Saint-Michel reveals that even with significant energy extraction (up to 55%), the effect on local currents remains minimal. This finding is critical for balancing renewable energy development and ecological preservation, especially in macro-tidal environments like this UNESCO World Heritage Site. Researchers used the MARS3D hydrodynamic model to simulate tidal dynamics, validated against recent current measurements. They then evaluated the potential energy hotspots and modeled the impact of turbine deployment by introducing an energy extraction term into the model equations. The results indicate that small-scale turbine farms could harness substantial energy with negligible disruption to local hydrodynamics.

Impact metamorphism at the Cretaceous-Paleogene Boundary and High-pressure Mineral Physics

Anjar — 2012 — WHE925ECA222F

Research at the UNESCO World Heritage Site of Anjar, India, provides compelling evidence for impact metamorphism at the Cretaceous-Paleogene Boundary (KPB). The study identifies the presence of iridium-rich layers and toluene-insoluble high-pressure phases of fullerene C60 in acid-resistant carbonaceous matter from the Intertrappean sediments. Fourier transform infrared (FT-IR) spectroscopic analysis revealed characteristic absorption peaks at 1381, 741, 608, and 542 cm−1, indicative of non-hydrostatic high-pressure and temperature conditions. These findings strongly support an impact origin for the fullerenes at the KPB, contributing to the understanding of this critical period in Earth's history.

Impact of Shrimp Farm Effluent on Water Quality in Coastal Areas of the World Heritage-Listed Ha Long Bay

Ha Long Bay - Cat Ba Archipelago — 2012 — WHEC13818BDCB

Shrimp farming in the UNESCO World Heritage-listed Ha Long Bay significantly degrades water quality, with effluent containing high levels of nutrient waste causing eutrophication. Research found that concentrations of Total Ammonia Nitrogen (TAN), Nitrite-Nitrogen (NO2-N), Nitrate-Nitrogen (NO3-N), Total Phosphorus (TP), Dissolved Orthophosphate (PO4-P), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Chlorophyll-a (Chl-a) were markedly higher in tidal creeks directly receiving shrimp farm effluent compared to adjacent areas. These levels exceeded recommended thresholds for aquatic ecosystem protection, particularly after the main shrimp crop season. The study employed spatial and temporal sampling across three locations—inside effluent-receiving creeks, outside concentrated farms, and distant from farms—to assess water quality parameters using standard methods. Principal Component Analysis (PCA) revealed distinct patterns of nutrient co-variation, underscoring the urgent need for stricter environmental regulations to sustain Ha Long Bay's marine ecosystem.

Impacts of climate variability and human colonization on the vegetation of the Galápagos Islands

Galápagos Islands — 2012 — WHE13315B95F8

A 2690-year fossil pollen record from the Galápagos Islands reveals that vegetation changes were primarily driven by shifts in species abundance rather than immigration or extinction, with droughts during the Medieval Climate Anomaly inducing rapid but reversible ecological shifts. Human colonization significantly altered the ecosystem, leading to the decline of native species like Alternanthera and Acalypha before 1930 and their potential local extinction due to intensified animal husbandry. Post-1970 reductions in grazing animals did not restore the native flora but instead facilitated exotic species invasions, accelerating habitat change beyond historical variability. The study also suggests increased lowland pollen transport to uplands, consistent with warmer wet seasons and intensified convection.

Kaeng Krachan Forest Complex — 2012 — WHE4A830F8093

Land use changes significantly influence soil erosion risk in Pa Deng sub-district, adjacent to Kaeng Krachan National Park, Thailand. The study found that smaller land cover areas exhibit higher soil erosion risk compared to larger ones over the 1990-2010 period. Researchers applied remote sensing, geographical information systems (GIS), and the Universal Soil Loss Equation (USLE) to assess these impacts. This approach revealed a clear relationship between land use patterns and soil degradation, emphasizing the importance of monitoring and managing land cover to mitigate erosion effects.

Importance of dead wood resources for woodpeckers in coniferous stands of the Białowieża Forest

Białowieża Forest — 2012 — WHE5FD0DC973F

Research in the Białowieża Forest reveals that woodpecker populations, particularly sensitive species such as the Three-toed Woodpecker and White-backed Woodpecker, thrive in coniferous stands with abundant dead wood resources. The study, conducted across three management zones—primeval unmanaged stands (BNP), partially managed reserves (RES), and heavily managed stands (MAN)—found that woodpecker indices were highest in BNP, where dead standing trees were most dense, and lowest in MAN, where dead wood was scarce. While RES supported the greatest species diversity, its dead wood abundance lagged behind BNP. The findings underscore the critical role of dead wood in sustaining woodpecker populations and suggest that management regulations in Polish nature reserves should prioritize retaining at least 2 m² per hectare of freshly killed spruce after bark beetle outbreaks to preserve biodiversity.

Improving archaeological site analysis: a rampart in the middle Orkhon Valley investigated with combined geoscience techniques

Orkhon Valley Cultural Landscape — 2012 — WHE550C7B60C2

A rampart in the Orkhon Valley, Mongolia, was dated to the Turk/Uighur period (6th–9th century AD) with potential reuse during Mongolian rule (12th–17th century AD), marking it as one of the farthest walled structures from Khar Balgas. The study combined geophysical techniques—including SQUID magnetometry, ground-penetrating radar, and electric resistivity measurements—with high-resolution topographic mapping to analyze MOR-2, a challenging site with scarce surface finds. Sediment cores from a nearby meander revealed increased organic content during Medieval times, supporting the dating hypothesis. While the rampart's specific function remains unclear, its construction aligns with known Uighur sites, offering new insights into Eurasian Steppe settlement history.

Influence of basin characteristics on baseflow and stormflow chemistry in the Great Smoky Mountains National Park, USA

Great Smoky Mountains National Park — 2012 — WHEE1C151C9C5

Streams in higher-elevation basins (>975 m) within the Great Smoky Mountains National Park exhibit significantly lower pH, acid neutralizing capacity (ANC), sodium, and silicon concentrations, alongside elevated nitrate levels, compared to those in smaller or lower-altitude basins. The study reveals that basin characteristics—such as elevation, area, geology, soil properties, and vegetation—interactively influence stream chemistry during both baseflow and stormflow conditions. Notably, streams draining basins with Anakeesta geology (>10%) show reduced pH and sodium but higher aluminum concentrations during storm events. Soil hydraulic conductivity emerges as a critical factor, with higher conductivities correlating to lower ANC, base cations, and increased nitrate/sulfate in stormflow. These findings underscore the dominant role of soil and geological properties over topographical factors in shaping aquatic chemistry, guiding prioritization for conservation strategies.
