Patterns of Arctic Sea-Ice Loss: Melt versus Export // Sep 6, 2018
Following up on my previous video, posted September 5th 2018 as Arctic Sea Ice Melt Patterns and Analysis, the summer melting characteristics for Arctic Sea-Ice are definitely changing.
Melt occurs on:
- 1) the top of the ice (air temperature above freezing, melt ponds, water within/between ice crystals, and ash/dirt in ice lower albedo),
- 2) the edge of the ice (wave action fracturing, water mixing, turbulence),
- 3) the bottom of the ice (water above freezing, fresh water lens, warmer salty water below).
Also, ice is exported out:
- a) the Fram Strait (less now as ice retreats),
- b) to the Atlantic north of Svalbard,
- c) out the Nares Strait (more now) and
- d) out the Canadian Archipelago channels (more now; no ridged ice left to block it).

Further Dynamics of Arctic Sea Ice Loss // Sep 7, 2018
Following up on my previous 2 videos, the mechanisms for ice loss (surface melt, edge melt, bottom melt, export out Fram Strait, Nares Strait, Canadian Archipelago) are in flux.Understanding the dynamics of the melt is necessary to get a better educated guess on when the first total ice loss (blue ocean event) will occur, how long it will last, and how it will precondition the Arctic Ocean for subsequent years.
I make use of Zack Labe’s excellent Arctic Sea Ice graphics to explain to you many of the dynamics of Arctic Sea ice Loss.

Arctic Sea-Ice Loss as a Pivot Point for Humanity // Sep 8, 2018
Fourth video of a series of four on the changing dynamics of Arctic Sea-Ice Loss (melt versus export) as we tease out clues as to when the first blue-ocean event will occur. Also:
- what will happen after the first blue-ocean event, both in the Arctic and elsewhere?
How will things proceed in subsequent years, and what impacts will humanity have to face?
