Just north of Cape Morris Jesup, several other small islands had been discovered over the decades, and then disappeared. But there was a mystery afoot in the region. The discoverers named it Qeqertaq Avannarleq - Greenlandic for the northernmost island. It was small and gravelly, and it was declared a contender for the title of the most northerly known land mass in the world. In 2021, an expedition off the icy northern Greenland coast spotted what appeared to be a previously uncharted island. The highly unlikely "bottom blooms," which grow near the seafloor in the Arctic and below sea ice in Antarctica, could support hidden ecosystems that scientists know nothing about.Īrctic 'ghost island' that vanished may have actually been a iceberg grounded at the sea bottom Live Science - September 15, 2022 Logic-defying phytoplankton blooms have been discovered lurking beneath the ocean's surface in both of Earth's polar regions, two unrelated new studies have revealed. Logic-defying 'bottom blooms' could sustain hidden ecosystems in Arctic and Antarctica Live Science - November 18, 2022Ī pair of new studies has revealed 'highly unlikely' phytoplankton blooms appearing near the seafloor and under sea ice at both Earth's poles. The scientists found genetic traces of elephant-like mastodons, reindeer and geese that roamed among birch and poplar trees, and of marine life including horseshoe crabs and algae. Today the area in North Greenland is a polar desert, but the genetic material, extracted from soil, has uncovered a rich array of plants and animals. The most ancient DNA ever sequenced reveals what the Arctic looked like two million years ago when it was warmer. Oldest DNA reveals two-million-year-old lost world BBC - December 7, 2022 Surprising loss of sea ice after record-breaking Arctic storm is a mystery to scientists Live Science - December 7, 2022Īlthough models accurately predicted the evolution of the Arctic storm, scientists were surprised to see just how much sea ice thickness decreased in the storm's aftermath. Life in the Arctic includes organisms living in the ice, zooplankton and phytoplankton, fish and marine mammals, birds, land animals, plants and human societies. In recent years the extent of the sea ice has declined. The cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. The Arctic region is a unique area among Earth's ecosystems. Socially and politically, the Arctic region includes the northern territories of the eight Arctic states, although by natural science definitions much of this territory is considered subarctic. Alternatively, it can be defined as the region where the average temperature for the warmest month July is below 10° C (50° F) the northernmost tree line roughly follows the isotherm at the boundary of this region. The area can be defined as north of the Arctic Circle (66° 33'N), the approximate limit of the midnight sun and the polar night. The Arctic region consists of a vast ocean with a seasonally varying ice cover, surrounded by treeless permafrost. The Arctic consists of the Arctic Ocean and parts of Alaska (United States), Canada, Finland, Greenland (Denmark), Iceland, Norway, Russia, and Sweden. The Arctic is a polar region located at the northernmost part of the Earth. Arctic - North Pole - Seed Vault - Crystalinks
