The year 2020 has thrown yet another curveball our fashion , in the form of a coloration - vary lake .
Lonar Lakelies in a meteorite impingement volcanic crater in Maharashtra State , India , some 500 kilometers ( 311 miles ) east of Mumbai , and is commonly dated to around 50,000 years ago ( although late dating suggest it could bea lot honest-to-goodness ) . before this week the normal blueish - green hue of the lakereportedly turnedto a reddish - pinkish color . Whilst further tests need to be pack out to determine the exact cause , experts have hint that changing saltiness levels and the presence of a specific algae in the lake could be to fault .
According tolocal - knowledge and disc , a similar color - change was witness around 2000 , but did not earn as much attention , nor was it as prominent . This meter , lake water samples have been send off to the National Environment Engineering Research Institute ( NEERI ) for psychoanalysis to bring out the exact grounds for the phenomenon . In the lag , local geologist , Gajanan Kharat offer up his account in a television onMaharashtra Tourism ’s Twitter Feed .
“ Salinity in the lake has increase as water level has gone down drastically this class and it has become warm too result in overgrowth of algae , ” Kharat was quoted as say byAFP . “ This alga turns reddish in warmer temperatures and hence the lake turn pink overnight . ”
Indeed , other experts , such as Professor Suresh Mapari , suggest to local newspaperLokmatthat the vent of a crimson pigment ( carotenoid ) by a with child bloom ofHalobacteriaandDunaliella salinaalgae was the perpetrator . Although for him , the trigger for this stay unreciprocated at present tense .
The 150 - metre - deep ( 500 foot ) and 1.8 - km - wide ( 1.12 land mile ) encroachment volcanic crater , is one of the largest known to exist inbasaltic(volcanic ) rock anywhere on Earth . This caused some confusedness with geologist when the volcanic crater wasoriginally discovered in the nineteenth century , as they believed it to be of volcanic origin . However , the crater has since been attributed to a cosmic encroachment due to the presence ofmaskelynite , a of course fall out chicken feed only formed by extremely high - velocity impact .
scientist from across the globe have go along to be intrigue by both the volcanic crater and its lake . The water itself is both alkaline and saline solution , and in 2007 grounds forbiological nitrogen fixation(conversion of atmospherical nitrogen to ammonia ) was discovered . This late development will certainly add another colorful chapter to Lonar Lake ’s history .
