We republish it today because of its renewed relevance. Aprile Pazzo was about to call it a day when she noticed that the penguins she was observing seemed strangely agitated. Pazzo, a wildlife biologist, was in Antarctica studying penguins at a remote, poorly explored area along the coast of the Ross Sea. Somehow the ice beneath the bird had melted; the penguin was waist deep in slush.
Fishing activities take up four times as much area as agriculture—and can now be monitored in real time By Tom Yulsman February 25, 1: An interactive website powered by a dataset and algorithm detailed in a new study allows the global footprint of fishing to be tracked in real-time — down to the level of individual vessels.
See below for details on how to use the website. But just how much of the oceans are being fished at an industrial scale, what are the patterns, and how are they changing over time?
|Antarctica () - johnromie||Introduction It has been only years since humans first occupied the continent of Antarcticaand a mere years since seafarers first saw the islands of the Antarctic Peninsula Yet even before they laid eyes on it, most early explorers were convinced a large, southern continent existed.|
|Toad (species) - Super Mario Wiki, the Mario encyclopedia||Economic resources Exploration for resources Antarctica, it has been suggested, may have become a continent for science because it was useful for nothing else. Certainly, the great success of the Antarctic Treaty and of the political experiment in international cooperation is in no small way attributable to the fact that exploitable mineral resources have not been found.|
And now, scientists have come up with some answers. That footprint is, in a word, gargantuan. You can also stop the animation at any time and zoom in all the way to the level of an individual vessel. From here you can play an animation of all fishing activity in the area, month-by-month, over the course of a year.
Global Fishing Watch The new tool could help with management of one of the most important sources of protein in our diets.
Consider that 70 percent of the oxygen we breathe is produced by phytoplankton in the oceans. Continuing down this path will ultimately lead to depletion of the fish stocks — and even an abrupt crash, from which recovery is exceedingly difficult, if not impossible. Fishing activity globally as measured by fishing hours per square kilometer.
Global Fishing Watch To construct it, Costello and his partners relied on the Automated Identification System carried by boats larger than a certain size. The researchers also made sure to cross-check their analyses against actual ship log books.
Among the research findings: Most nations fish within their exclusive economic zones.In total the area boasts roughly km2 of exposed blue ice, easily noticed in aerial imagery by ANSMET personnel in the s.
The blue ice - meteorite . When all the sea-ice in the Arctic has vanished from melt and transport, what will happen? This so-called Blue-Ocean-Event (BOE) in the Arctic will mean that the last bastion of ice and coldness in the Arctic will be Greenland.
This data set is the result of a study of volcanic ash and rock fragment (tephra) layers in exposed blue ice areas on Brimstone Peak (S E) in East Antarctica. Tephra samples were collected between 15 November and 15 January A growing number of foundations and wealthy individuals are concerned about environmental threats to oceans and rivers.
Funders take many approaches: some are narrowly focused on specific geographic areas, whiles others giving more broadly.
A Tour of the Cryosphere Visualizations by Alex Kekesi and Cindy Starr Released on September 1, The cryosphere consists of those parts of the Earth's surface where water is found in solid form, including areas of snow, sea ice, glaciers, permafrost, ice sheets, and icebergs.
A Loftleidir Icelandic crew became the first to land a Boeing passenger jet on a blue ice runway on earth's southernmost continent - bringing it closer to tourists than ever before.
