Palaeolimnology of Lake Sapanca and identification of historic earthquake signals, Northern Anatolian Fault Zone (Turkey) [PDF]

open access: yes, 2009
Lake Sapanca is located on a strand of the Northern Anatolian Fault Zone (NAFZ, Turkey), where a series of strong earthquakes (Ms >6.0) have occurred over the past hundred years. Identifying prehistoric earthquakes in and around Lake Sapanca is key to a

Diatoms in the Bottom Sediments of Two Closely Located Lakes in Khakassia [PDF]

open access: yesЖурнал Сибирского федерального университета: Серия Биология, 2018
Diatoms are one of the main paleo-indicators of lake changes, as they are preserved in bottom sediments for centuries. The present study reports new data on diatoms in the bottom sediments of Lake Shira and compares them with diatoms from the bottom ...

Prevalence, source and risk of antibiotic resistance genes in the sediments of Lake Tai (China) deciphered by metagenomic assembly: A comparison with other global lakes

open access: yesEnvironment International, 2019
Lakes are one of the natural reservoirs of antibiotic resistance genes (ARGs) in environments. Long retention times in lakes potentially allow ARGs to persist and may create increased opportunities for the emergence of resistant pathogens. In this study,

Contamination of surface waters by mining wastes in the Milluni Valley (Cordillera Real, Bolivia): Mineralogical and hydrological influences [PDF]

open access: yes, 2008
This study is one of very few dealing with mining waste contamination in high altitude, tropical-latitude areas exploited during the last century. Geochemical, mineralogical and hydrological characterizations of potentially harmful elements (PHEs) in ...

Spatial and temporal variations of Rb/Sr ratios of the bulk surface sediments in Lake Qinghai

open access: yesGeochemical Transactions, 2010
The Rb/Sr ratios of lake sediments have been suggested as indicators of weathering intensity by increasing work. However, the geochemistry of Rb/Sr ratios of lake sediments is variable between different lakes.

Refining the interpretation of lacustrine carbonate isotope records: Implications of a mineralogy-specific Lake Van case study [PDF]

open access: yes, 2019
Oxygen and carbon isotope (δ18O and δ13C) data from bulk carbonates are widely applied proxies for temperature, the precipitation/evaporation ratio and productivity in lacustrine palaeohydrology and palaeoclimatology. In case of the terminal and alkaline
