Reconstruction the climatic changes of the last 600 years in Southeast Iran, study area, the Lake Sardarya, Taftan Volcano
Introduction: In order to recognize the mechanism of local climatic settings and to be able to establish the future climatic scenarios is essential to understand the past climatic and environmental conditions of the each area. This is also important to explore the response of local areas to the global climatic variations. The palaeoclimate researches carried out in Iran mainly considered the g...
متن کاملHow well do sediment indicators record past climate? An evaluation using annually laminated sediments
The reliability of paleoclimatic inferences from lake-sediment records rests on the understanding of how various sediment indicators respond to environmental changes. Despite the recent proliferation of paleoclimatic records, only a limited number of studies have rigorously evaluated potential indicators by comparing lake-sediment records with instrumental weather data. We analyzed annually lam...
متن کاملDeciphering climatic history from lake sediments
Reconstructing climate from lake sediments can be challenging, because the response of lakes and various components of lake systems are mediated by non-climatic factors, such as geomorphic and hydrologic stetting. As a result, the magnitude of lake response to climatic forcing may be non-linear. In addition, changes in the lake system associated with the aging process or non-climatic influences...

عصر روشنگری زمان شکل گیری ایده های مدرن تربیتی- آموزشی بود اما تاکید بیش از اندازه ی دوشاخه مهم فلسفی زمان یعنی عقل گرایی و حس گرایی بر دقت و وضوح، انسان عصر روشنگری را نسبت به دیگر تواناییهایش نابینا کرده و موجب به وجود آمدن افرادی تک بعدی شد که افتخارعقلانیتشان، تاکید شان بر تجربه فردی، به مبارزه طلبیدن منطق نیاکانشان وافسون زدایی شان از دنیا وتمام آنچه با حواس پنجگانه قابل درک نبوده و یا در ...
Five thousand years of sediment transfer in a high arctic watershed recorded in annually laminated sediments from Lower Murray Lake, Ellesmere Island, Nunavut, Canada
Sediments in Lower Murray Lake, northern Ellesmere Island, Nunavut Canada (81 210 N, 69 320 W) contain annual laminations (varves) that provide a record of sediment accumulation through the past 5000? years. Annual mass accumulation was estimated based on measurements of varve thickness and sediment bulk density. Comparison of Lower Murray Lake mass accumulation with instrumental climate data, ...
