After a short search, the MOSAiC team found a new ice floe. The so-called MOSAiC floe 2.0 was discovered eleven nautical miles from the route that the original floe took in January 2020. [17] Polarstern left the MOSAiC floe 2.0 on 20 September 2020, one year after the start of the expedition.
Polar ecology is the relationship between plants and animals in a polar environment. Polar environments are in the Arctic and Antarctic regions. Arctic regions are in the Northern Hemisphere , and it contains land and the islands that surrounds it.
Polar seas is a collective term for the Arctic Ocean (about 4-5 percent of Earth's oceans) and the southern part of the Southern Ocean (south of Antarctic Convergence, about 10 percent of Earth's oceans). In the coldest years, sea ice can cover around 13 percent of the Earth's total surface at its maximum, but out of phase in the two hemispheres.
2017: Polar Row, led by Fiann Paul, is the world's most record-breaking expedition (14 Guinness World Records). The team covered 1440 miles measured in a straight line in the Arctic Ocean open waters in a row boat and pioneered ocean rowing routes from Tromsø to Longyearbyen, from Longyearbyen to Arctic Ice Pack (79º55'500 N) and from the ...
Also known as Arctic bases, polar stations or ice stations, these bases are widely distributed across the northern polar region of Earth. Historically few research stations have been permanent. Most of them were temporary, being abandoned after the completion of the project or owing to lack of funding to continue the research.
The Polar Earth Observing Network (POLENET) is a global network involving researchers from 24 nations for the geophysical observation of the polar regions of our planet. [1] POLENET focuses mainly on data collection of GPS (Global Position System) and seismic sensors, by means of autonomous systems. Its research includes geophysical ...
The Cretaceous is characterized by warm global temperatures caused by the high amounts of carbon dioxide and possibly methane greenhouse gases in the atmosphere. This caused a lack of permanent ice coverage in the polar regions, though the carbon dioxide level dropped between 115 and 66 million years ago (mya), possibly allowing some permanent ice cover.
Polar ecosystems are particularly sensitive to climate change, where small changes in temperature result in greater changes in local hydrology, dramatically affecting ecosystem processes. [ 3 ] Soils in Antarctica are nearly two-dimensional habitats, with most biological activity limited to the top four or five inches by the permanently frozen ...
