Cool Geo-Pic: Currents Collide and Coastal Waters Bloom off Patagonia
This Cool Geo-Pic comes again from NASA's Earth Observatory. I love the nutrient patterns based on the blooms from change ocean currents. The pathways from my fridge to the couch are much less interesting ....
Quick "Cut & Paste" Highlights:
" ...Located over the continental shelf of southeastern South America is one of the world’s most productive and complex marine ecosystems. Covering about 1.2 million square kilometers (4.6 million square miles) of coastal waters, the Patagonia Large Marine Ecosystem stretches from the Rio de le Plata (a wide estuary at the mouth of the Paraná River) to the southern tip of the continent...."
"... In November 2009, as summer approached in the Southern Hemisphere, the foundation of the ecosystem’s food web—plant-like microorganisms called phytoplankton—bloomed expansively, brightening the waters with living ribbons of color...."
"....The sea surface temperature image (right) reveals one of the reasons for the region’s productivity: the convergence of two wind-driven ocean currents. The warm, salty Brazil Current meanders south over the continental shelf, where it meets the cold, less-salty Falklands/Malvinas Current, a north-flowing branch off the Antarctic Circumpolar Current...."
"....In the spring and summer, the convergence zone occurs at about the latitude of the Rio de la Plata, which is where it seems to be based on the water temperatures shown in the sea surface temperature image. Blues and purples (cooler water) dominate the image south of the estuary, while pinks and yellows (warmer water) dominate the image north of there...."

Aqua has been collecting data on the ecological and physical state of the ocean since its launch in 2002. Monthly maps of chlorophyll and sea surface temperature from Aqua are available in Global Maps on the Earth Observatory.

Cool Geo-Pic: Winter Temperatures and the Arctic Oscillation
This Cool Geo-Pic comes again from NASA's Earth Observatory. What I find fascinating is that the changes in climate patterns vary by geography, terrain and element (land/water).
Quick "Cut & Paste" Highlights:
" ... Much of the Northern Hemisphere experienced cold land surface temperatures, but the Arctic was exceptionally warm. This weather pattern is a tale-tell sign of the Arctic Oscillation.
The Arctic Oscillation is a climate pattern that influences winter weather in the Northern Hemisphere. It is defined by the pressure difference between air at mid-latitudes (around 45 degrees North, about the latitude of Montreal, Canada or Bordeaux, France) and air over the Arctic. A low-pressure air mass usually dominates the Arctic, and while higher pressure air sits over the mid-latitudes.
This pressure difference generates winds that confine extremely cold air to the Arctic. Sometimes, the pressure systems weaken, decreasing the pressure difference between the Arctic and midlatitudes and allowing chilly Arctic air to slide south while warmer air creeps north..... When the pressure systems are strong, the Arctic Oscillation is positive.... Cold Arctic air chilled the land surface at midlatitudes, while Arctic land, such as Greenland and Alaska, was much warmer than usual...."

Cool Geo-Pic: A Global Good Mornin' to Ya
This cool Geo-Pic shows "Good Morning" tweets.
Full credits to Jer Thorp : blog.blprnt.com GoodMorning! Full Render #2 from blprnt on Vimeo.
Per the site: " GoodMorning! is a Twitter visualization tool which shows about 11,000 tweets collected over a 24 hour period between August 20th and 21st. The tweets were harvested to find people saying 'good morning' in English as well as several other languages.The tweets appear as blocks and are colour-coded. Green tweets are early in the morning, orange tweets are at about 9am, and red tweets are later in the morning. Black tweets are 'out-of-time' messages (sent at times that aren't in the morning at that location)....."

Cool Geo-Pic: Planetary Visualization of the S&P 500
This Cool Geo-Pic blends planetary rotations to stock performance. Helps me understand why my stock portfolio went from the size of Jupiter to the mini-moon of Pluto.
