Cool Geo-Pic: Mapping Earthquakes in Chile

Another cool geo-pic from NASA/s Earth Observatory.  I like the analysis on the historical rippling to other areas.

Quick Cut and Paste:

"The maps above show how the Earth moved in mid-September …..the amount of land motion is represented in shades from yellow to purple. Areas where the ground shifted the most (vertically, horizontally, or both) are represented in yellow, while areas with little change are represented in purple.  …Interferograms can be used to estimate where the fault moved deep in the Earth and which areas have increased stress and higher likelihood of future earthquakes…"

Cool Geo-Video: Sports Timeline linked to Twitter Activity

Here is another cool geo-video built on the CartoDB platform.  Nice timeline relating the game scores to twitter reaction.

Cool Geo-Video: "Sunrise" around the world by Twitter

Recently made the move from Esri to Deloitte Geospatial.  While I will always be an advocate of the Esri platform, the "brand independence" has given me the opportunity to broaden the consideration of WebGIS tools to be truly "platform agnostic". Recently we've been tooling around with CartoDB - here are some of my favorite samples - blending a live twitter feed with WebGIS.

Cool Geo-Video: Mapping Dust from the Sahara to the Amazon

Cool Geo-Pics from NASA's Earth Observatory.



Quick "Cut & Paste":
"....Hundreds of millions of tons of sand and dust particles are lifted from North African deserts each year and carried across the Atlantic Ocean. So much dust is kicked up that the microscopic particles amass into sweeping tan plumes that are visible to satellites......"

"....The data show that wind and weather pick up on average 182 million tons of dust each year and carry it past the western edge of the Sahara. The dust then travels 1,600 miles across the Atlantic Ocean, though some drops to the surface or is flushed from the sky by rain. Near the eastern coast of South America, 132 million tons remain in the air and 27.7 million tons fall to the surface over the Amazon basin....."

Cool Geo-video: Mapping Mega-Droughts

This cool geo-video comes from NASA science in an effort to communicate drought risk base on past drought & soil moisture to drive climate modeling scenarios to estimate the risk & impact of future drought in the 21st century.

Cool Geo-Pic: "Net-net" Global Sea Ice is Shrinking

Today's cool geo-pic is again from NASA's Earth Observatory. It provides a "net-net" comparison of polar ice loss, and comes to the conclusion that global sea ice is still shrinking.

"Cut & Paste" Highlights:
"....Examining 35 years of sea ice data, Parkinson has shown that increases around Antarctica do not make up for the accelerated Arctic sea ice loss of the last decades. Earth has been shedding sea ice at an average annual rate of 35,000 square kilometers (13,500 square miles) since 1979—the equivalent of losing an area of sea ice larger than the state of Maryland every year...."

.... “Even though Antarctic sea ice reached a new record maximum in September 2014, global sea ice is still decreasing,” said Parkinson, who is based at NASA’s Goddard Space Flight Center. “That’s because the decreases in Arctic sea ice far exceed the increases in Antarctic sea ice.....”

".....The line graphs above plot the monthly deviations and overall trends in polar sea ice from 1979 to 2013 as measured by satellites. The top line shows the Arctic, the middle shows Antarctica, and the third line shows the global, combined total. The sparklines at the bottom of the graphs show each year separately, enabling month-to-month comparisons across each year. The thickness of each sparkline indicates the overall growth or loss in sea ice globally. The thinning of the sparklines is indicative of the downward trend in total polar sea ice......"
