I wonder when this stable situation might change
Indeed, there has not been a progressive retreat of the front the last ten years; calving continues but more or less in balance with the glacial ice moving down the hill.
The big retreat years involve buttressing melange melting away early and high melt inflow upstream. However fundamental changes are often attributed to warming ocean water eating away at the base.
The S2 imagery Espen provided has a slight tint to it, perhaps because it is low angle early season. Splitting the initial RGB into 3 grayscale channels and comparing by differencing, it appears that the red channel alone has better quality than the full RGB.
The question is, do the green and blue channels somehow carry additional information about the ice below and if so, what.
