Snowball Earth: A thin-ice solution with flowing sea glaciers
[1] The late Neoproterozoic era, 600–800 Myr ago, was marked by at least two intervals of widespread cold that left glacial deposits at low paleolatitudes. Both ‘‘Snowball’’ solutions with global ice cover and ‘‘Slushball’’ solutions with ice-free tropical oceans have been proposed to explain the paleomagnetic data. The Snowball model is best able to explain the auxiliary geological evidence, p...
متن کاملRapid changes in ice discharge from Greenland outlet glaciers.
Using satellite-derived surface elevation and velocity data, we found major short-term variations in recent ice discharge and mass loss at two of Greenland's largest outlet glaciers. Their combined rate of mass loss doubled in less than a year in 2004 and then decreased in 2006 to near the previous rates, likely as a result of fast re-equilibration of calving-front geometry after retreat. Total...

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
15 صفحه اولOrigin of stratified basal ice in outlet glaciers of Vatnajökull and Öræfajökull, Iceland
During the period 2000–2005, we collected samples of englacial ice, vent water, frazil/anchor ice and stratified basal ice from warm-based outlet glaciers of Vatnajökull and Öræfajökull, Iceland, and analysed them for H, O and D. Results of H analyses show that the stratified basal ice contains H from atmospheric thermonuclear testing and is younger than the englacial ice. Results of the O and ...
متن کاملRadar Measurements of Ice Sheet Thickness of Outlet Glaciers in Greenland
We have conducted airborne measurements over the Greenland ice sheet from the NASA P-3B aircraft using a 150MHz coherent radar depth sounder to obtain extensive ice sheet thickness measurements. Simultaneous measurements of ice sheet elevation were also made using a laser altimeter. In outlet glacier areas along the ice sheet margin, the ice surface is characterized by a very rough, crevassed s...
