NASA’s ER-2 aircraft found the enormous melt pond after it appeared on an unnamed glacier in Alaska. Its lively blue color is an outcome of how the immersed ice takes in sunshine.

FAST FACTS
Where is it? An unnamed glacier in southeastern Alaska
What’s in the image? A big swimming pool of water sitting on top of the ice
What took the image? NASA’s ER-2 plane
When was it taken? July 16, 2014
This 2014 aerial image reveals what appears like an uncommonly big and deep puddle of lively blue meltwater sitting on top of an unnamed Alaskan glacier. Comparable melt ponds are ending up being more typical throughout the Arctic due to environment modification and are additional speeding up the rate at which the area is losing its ice.
The striking melt pond, which is cluttered with numerous small icebergs, is around 2,300 feet(700 meters) throughout at its best point. The swimming pool’s dynamic blue color makes it look like it is remarkably deep. This is most likely simply an impression triggered by the ice listed below. Usually, Arctic sea ice melt ponds are just around 9 inches(22 centimeters )deep, according to a 2022 research studyIt is uncertain precisely how deep this puddle is.
Zoomed-out variations of the picture program that the melt pond was surrounded by absolutely nothing however snow for miles. Generally, melt ponds are organized close together in clusters. It is uncertain what triggered this pond to grow so big in seclusion.
The icy lagoon was identified by the Multiple Altimeter Beam Experimental Lidar (MABEL) instrument onboard NASA’s ER-2 aircraft– an unique research study airplane that can fly more than two times as high as business jets. The airplane was sweeping the location as part of a broader study of Arctic melt ponds, and it caught numerous comparable pictures. This pond was one of the biggest observed, according to NASA’s Earth Observatory

Melt ponds form in late spring and early summertime as the ice defrosts from the heat and the resulting water swimming pools in anxieties within the ice. These functions have actually constantly existed in the Arctic. They have actually ended up being much more typical in current years due to the impacts of human-caused environment modification
The increased look of melt ponds is worrying for scientists due to the fact that the dark blue puddles take in a lot more sunshine than snow and ice do. This triggers the ponds to heat up and melt more of the ice around them, specifically when they appear on vulnerable sea ice. This “positive feedback loop” might wind up setting off a runaway result in which the rate of melting tremendously increases.

As an outcome, the variety of melt ponds that appear each summertime is an excellent predictor of a year’s Arctic’s minimum sea ice level, or the point at which the area of the area’s sea ice is least expensive, Mongabay just recently reported
In spite of the significance of keeping an eye on these melt ponds, some scientists state we still do not comprehend them enough to make such forecasts.
In a 2023 evaluation postspecialists composed that “limited observations of melt ponds are far from adequate,” which is causing a “lack of spatial and temporal scale-knowledge” about when and where they form. This cultivates unpredictability about their function in the environment crisis. This issue might be fixed by increasing the quantity of aerial observations of the Arctic and utilizing synthetic intelligence to assist comb through the information, the evaluation authors argue.
