Lake

By NASA Earth Observatory July 17, 2023The stark color contrasts on the east and west banks of the Egyptian Lake Nasser are due to the varying amounts of sand coverage, with more sand resulting in lighter hues and less sand exposing darker soil.Differences in the amount of sand cover explain the starkly contrasting colors of the Egyptian lake’s west and east banks.An astronaut aboard the <span class="glossaryLink" aria-describedby="tt" data-cmtooltip="<div…

Scientists have picked the bottom of Crawford Lake in Ontario as the "golden spike" to mark the start of a new proposed geological epoch — the Anthropocene. The announcement was made at a media conference in Berlin Tuesday by a group of scientists called the Anthropocene Working Group — more on them later. Here's why the lake was chosen and what evidence it provides that humans have made such big changes to the Earth that we may be in a new geologic time period.Crawford Lake is unusually deep compared to its surface area.…

Like the pages of a diary hidden beneath a child's bed, the floor of Crawford Lake in Ontario, Canada, preserves Earth's most recent memories in clear, chronological order.The story within its laminated sediments is dominated by humans, detailing at an annual resolution the activities of local Iroquoian communities in the late 13th to 15th centuries, through the arrival of the European colonists to today.For this reason, a team of experts nominated the UNESCO Biosphere Reserve as the site that ought to represent the…

Ever since her clear and unequivocal loss in the race for Arizona governor, Kari Lake has traveled the country posing and strutting like a conquering hero.As a candidate, the former Fox TV anchorwoman was all in on former President Trump and his Big Lie about the 2020 election being stolen. Her brazen duplicity is probably what cost Lake the gubernatorial contest in November.But in characteristic fashion, she’s refused to acknowledge defeat, filing a lawsuit — since thrown out of court — and widely peddling false claims…

LEMOORE, Calif. —  When Leo Sisco was growing up on his tribe’s reservation, he heard elders’ stories about the great lake that once sustained their people, and how it was drained and taken away from them.This year, Sisco has been witnessing a remarkable transformation as Tulare Lake has reappeared on low-lying farmland near the reservation.The chairman of the Santa Rosa Rancheria Tachi Yokut Tribe has been noticing the water is attracting many birds, and he has been coming regularly to the lakeshore to offer prayers…

Shoreline change is a problem plaguing many communities on the Great Lakes, as locals watch sections of it slip into the water.Now, the Maitland Valley Conservation Authority in southwestern Ontario has created urgently needed maps showing the huge impact of these shifts in temperatures and weather — large swaths of Lake Huron's shoreline could be under water in 100 years, including cottages, waterfronts and a marina. "It's really, to me, the most jarring thing to see," said Patrick Huber-Kidby about land that's already…

Edited by Dava Sobel 1. THE SOUTHERN LIGHTS AT –50° FAHRENHEIT —a zeitgeber When winds were bearable, we sought bliss, sat, admired the aurora australis as an escape from our blackest abyss. We gazed up into rarefied air, clear and pristine in every echelon, an atmospheric phenomenon, solar wind collisions of protons and electrons high in the exosphere. Who needs Parthenon or Birth of Venus when blue lights swirl low, pink coronas kiss clouds, neon greens arc, deep reds…

Intel will shake up its naming scheme for Core family CPUs with the launch of the 14th Gen later this year. The familiar Core i3, i5, i7 and i9 names denoting performance tiers will be retired after nearly 15 years and replaced with shorter Core 3, Core 5, Core 7 and Core 9 labels for mainstream consumer CPUs. However, a new set of Core Ultra 5, Core Ultra 7 and Core Ultra 9 tiers will also denote high-performance "leadership" models. Moreover, Intel will stop emphasising generation numbers on its stickers and in…
