~The legendary "Big Lead" exists, it shows up in various ways depending of date of year
~This February 26 2018 showing comes with lateral and perpendicular fractures with micro-fractures
~ This usually was an early June event....
Look very carefully North of Central Canadian Arctic Archipelago. To the left there will be a small cyclone moving East, it will bring out the Big Lead. A deeper look reveals a chaotic well battered sea ice prior to these lead creations. Right after or during the big coastal movement was like a tremor causing many lead fractures to bring out heat signatures, open water everywhere:
|This kind of break up action was a late May or early June event. This February 26 2018 badly broken up sea ice is a qualifier of current state of Arctic Ocean ice, looser, more fluid, a special feature of a not so long ago beginning of summer. However, Big Leads showed in February's not so distant past, but had a very typical look of a single lead parallel to the Canadian Arctic Archipelago Coast without the fractures, it opened and appeared to shut quickly, because air temperatures were very cold (-45 to -50C) , open water froze rapidly, drifting snow swiftly covered the fresh ice, tides also closed the gaps. It typically visually disappeared in 2 days. WD February 26, 2018|
