Akimiski Island, Canada

Scraped clean and weighted down for thousands of years by Pleistocene ice sheets, Akimiski Island in James Bay provides a case study of how Earth's land surfaces evolve following glaciation.

This image tells the story of Akimiski Island's recovery after the last Ice Age, when it was covered with glaciers so large they sunk the island. The layered scarring on highlighted in the lower image was caused by waves as the island rebounded and rose along with the rising oceans as glaciers melted.

 

I wonder what forces are at work to raise the elevation of the island, possibly just decompression from the millions of pounds of pressure the island was under during the Ice Age.

This set of maps and articles help to explain why sea level rise is such an issue for many major metropolitan areas.  In coastal cities with substantial economic development, much of the current coastal areas where once underwater until landfill projects filled in the bay.  During storm surges (or if and when sea levels rise) these will be the first places to flood.

James Hobson's curator insight, September 10, 2014 3:18 PM

Here's somehing to "Swett" over for those who live along the coast:

"Coastal cities are now living in what Brian Swett calls a “post-Sandy environment.” In this new reality, there is no more denying the specter of sea-level rise or punting on plans to prepare for it. And there is no more need to talk of climate change in abstract predictions and science-speak. We now know exactly what it could look like."

Keep in mind that as globalization expands, urbanizaion does as well, putting more and more people at this type of risk.

Seth Dixon's curator insight, March 8, 2013 8:03 AM

The United States Geologic Survey (USGS) scientists are encouraging app developers and earth scientists to design creative apps that will aid researchers in tackling the important questions. USGS datasets include biogeographical, vegetation and land cover change data. Submissions will be judged on their relevance to today’s scientific challenges, innovative use of the datasets, and overall ease of use of the application. Prizes will be awarded to the best overall app, the best student app, and the people’s choice.  Do you have an idea?
