Summary
[edit]DescriptionПоверхня озера Нар DSCF5603.jpg |
Українська: Озеро Нар (турецькою Narlıgöl - Гранатове озеро) є вулканічним кратерним озером типу маар. У цьому районі все ще існує геотермальна активність, яка породила гарячі джерела навколо озера. Геотермальна вода подається у сусідні готелі для використання в гарячих ваннах.
Площа озера 0.7 км2, середня глибина 21 м, висота над рівнем моря 1363 м. Озеро є домом для виду мікроскопічних діатомових водоростей під назвою Clipeoparvus anatolicus. Води озера Нар зазнають значних змін між сезонами. Взимку вода в озері холодна наскрізь. Коли температура навесні підвищується, вода в озері ділиться на верхню половину, яка є теплою (епілімніон), а нижня половина (гіполімніон) залишається холодною та безкисневою. Озеро Нар особливо відоме своїм значенням для науки. Керни відкладень, взяті з озера, були датовані шляхом підрахунку окремих шарів, що відклались тисячоліття назад. Лабораторний аналіз кернів цих осадових відкладень дозволив дуже детально відтворити історію клімату та діяльності людини. Наприклад, аналіз пилку показав, як арабські вторгнення в центральну Анатолію протягом 8-го і 9-го століть знищили пізньоантичну сільську економіку Каппадокії, засновану на вирощуванні дерев і злаків.English: Lake Nar (Turkish: Narlıgöl - Pomegranate Lake) is a volcanic crater lake of the maar type. There is still geothermal activity in the area, which has given rise to hot springs around the lake. The geothermal waters have been pumped up to nearby hotels for use in their hot baths.
The area of the lake is 0.27 sq mi, the average depth is 69 ft, the surface elevation is 4,472 ft. The lake is home to a species of microscopic diatom algae called Clipeoparvus anatolicus. The waters of Lake Nar undergo a remarkable change between different seasons. In winter, the lake water is cold from top to bottom. As the temperature increases in the spring, the lake water divides into an upper half which is warm (epilimnion), while the lower half (hypolimnion) stays cold and lacking in oxygen. Lake Nar is particularly known for its scientific importance. Sediment cores taken from the lake have been dated by counting individual layers back thousands of years. Laboratory analysis of these sediment cores has enabled the history of climate and human activities to be reconstructed in great detail. For example, pollen analysis has shown how the Arab invasions of central Anatolia during the 8th and 9th centuries destroyed Cappadocia’s late antique rural economy based on tree crops and cereal cultivation.English: Lake Nar near Narköy village, Turkey |
