'By-the-wind sailor' jellies wash ashore in massive numbers after warmer winters


Observations by citizen scientists help researchers find patterns in jellyfish strandings
Velella velella, also called “by-the-wind sailor” jellies, washed ashore at Moolack Beach, Oregon.
As their name suggests, by-the-wind sailor jellyfish know how to catch a breeze. Using a stiff, translucent sail propped an inch above the surface of the ocean, these teacup-sized organisms skim along the water, dangling a fringe of delicate purple tentacles just below the surface to capture zooplankton and larval fish as they travel.
At the mercy of the wind, these jellies, sometimes numbering in the trillions, can wash ashore on beaches around the world, including up and down the U.S. West Coast, in what is called a stranding event. While these mass stranding events are hard to miss, very little is known about how or why they happen. ....

Lakes on Greenland Ice Sheet can drain huge amounts of water, even in winter


Date Time
Lakes on Greenland Ice Sheet can drain huge amounts of water, even in winter
Using satellite data to ‘see in the dark’, researchers have shown for the first time that lakes on the Greenland Ice Sheet drain during winter, a finding with implications for the speed at which the world’s second-largest ice sheet flows to the ocean.
We don’t yet know how widespread this winter lake drainage phenomenon is, but it could have important implications for the Greenland Ice Sheet, as well as elsewhere in the Arctic and Antarctic
Ian Willis
The researchers, from the University of Cambridge, used radar data from a European Space Agency satellite to show that even when the heat from the Sun is absent, these lakes can discharge large amounts of water to the base of the ice sheet. These ‘drainage events’ are thought to play a significant role in accelerating the movement of the ice by lubricating it from below. ....

Lead Contamination Threat to Migrants Unresolved: Greece


Human Rights Watch
Dozens of families are still accommodated in areas of a migrant camp in Lesbos where soil testing showed elevated lead levels two months after the Greek government confirmed that the areas were contaminated, Human Rights Watch said today. The authorities have yet to conduct comprehensive soil testing inside the camp in the highest-risk areas to assess the extent of contamination.
The Greek government has known the risks since at least December 2020, when test results confirmed lead contamination in parts of the Mavrovouni camp, which houses nearly 6,500 migrants and asylum seekers. The government should have been aware of the risk and was specifically warned by media and civil society organizations shortly after the camp was opened in September because it was built on top of a small arms firing range that had been in use until the camp was opened. ....
