Oceanographers are carving up the world’s seas like the last of the
holiday turkey. A new 3D map sorts global water masses — from deep,
frigid circumpolar waters to the oxygen-starved Black Sea — into
map groups together marine regions of similar temperature, salinity,
oxygen and nutrient levels. It has been available for only a few months,
and researchers are still working through how they might use it. But
its international team of developers hopes that the map will help
conservationists, government officials and others to better understand
the biogeography of the oceans and make decisions about which areas to
preserve. It could also serve as a data-rich baseline for analysing
future ocean changes.
Many existing systems
also attempt to classify variations in the ocean, such as lists of large
marine ecosystems or the Longhurst biogeographical provinces that are
defined by the rate at which ocean life consumes carbon. But these are
often limited to surface or coastal ecosystems. The latest effort, known
as the ecological marine units (EMUs), is the most detailed attempt yet
to cover the global ocean in three dimensions.
often missing is all that’s between the surface of the ocean and the
ocean bottom,” says Dawn Wright, chief scientist of Esri, a geographic
information-systems company in Redlands, California, that helped to
develop the 3D map. “That’s what our project will hopefully bring to the

I’m gonna work on the Pisces area now. Thank to the Map God I finished all the mapping in Capricorn. I think I’ll have a huge post up later about the entirety of the game (mechanics, more details about the story, etc). Maybe this will be up tomorrow, since I’m very busy with tilesets today.
An 18 minute ski trip through the mountains and ice sheets in East Greenland, narrated by the folks who took it, plus some details on mapping and digitizing the landscape. This is pretty great.
On one of the wildest coastlines on Earth, a group of four skiers plan to climb and ski new routes. Setting out from a small Inuit village, and with very little recorded information available, they hope a new piece of mapping technology can help them commit to ski down faces they haven’t seen. Featuring glorious footage of this rarely visited region, this documentary will give viewers a glimpse into the stunning, endless mountain ranges of East Greenland.
