New Mapping Shrinking Glaciers
Alaska Ice: Documenting Glaciers on the Move is an Esri Story Map which uses satellite imagery too comparisons of modern & vintage photographs to document Alaska'a glaciers.
The principal focus of the map is the U.S. Geological Survey's Repeat Photography initiative. USGS has been comparing modern photographs of Alaskan glaciers alongside historical photos, both alongside the same plain of view. The photographs are compared to document too empathise the changes to glaciers resulting from changing climate.
The Alaska Ice Story Map visits xiv glaciers inward the U.S. state. Each glacier tin survive viewed on a satellite map too a modern too an historical photograph of each glacier is compared inward the map sidebar. Of the xiv mapped Alaskan glaciers solely 2 are however advancing.
Disappearing Glaciers is some other Esri StoryMap, this 1 is designed to highlight the alarming speed at which glaciers are disappearing to a greater extent than or less the world.
The map looks at recent aerial imagery of 6 unlike glaciers. Polylines convey been overlaid on each glacier aerial picture to demo the glacier's size through time, demonstrating how far each glacier has reduced over the years.
Timelapse - aerial imagery of the Mendenhall Glacier inward 1991 & 2012
Another interesting means to attempt out the loss of glaciers is alongside Google Timelapse. Timelapse allows you lot to compare aerial imagery over fourth dimension for whatsoever place on Earth. You tin hence come inward the advert of whatsoever glacier into Timelapse too detect the effects of global warming for yourself.
Timelapse provides links to the Medenhall Glacier too the Columbia Glacier exactly you lot tin purpose the search box to locate whatsoever glacier. You tin hence purpose Timelapse to search for the 6 glaciers used inward the Disappearing Glaciers map too detect the highlighted loss of each glacier for yourself, using the historical aerial imagery.
