Peggy’s data were a bit of a shock.From an anchored vantage point in an expanse of the southeastern Bering Sea west of Alaska, Peggy, or mooring M2, had monitored conditions in the water for 25 years. A line of sensors extended down more than 70 meters to where Peggy was tethered to the seafloor, collecting information on temperature, salinity and other properties of the water.Most years, the waxing and waning of floating sea ice follows a consistent seasonal pattern that is reflected in Peggy’s data. By November, sea ice migrates in through the Bering Strait or forms in some parts of the Bering Sea. As a by-product of the sea ice formation, a large mass of cold, salty water begins to pool near the seafloor. In the spring, phytoplankton bloom, and by early summer, the sea ice begins to melt away. The cold pool, however, lingers through the summer. With an average temperature just below zero degrees Celsius — a few degrees colder than the surrounding water — … [Read more...] about What happens when the Bering Sea’s ice disappears?
What polar bear eat
A combination of dwindling sea ice and an all-you-can-eat-buffet of garbage may be drawing a massive influx of polar bears to towns on a Russian archipelago. It’s a worst-case scenario for both the polar bears and people because proximity increases the potential for conflict. At least 52 polar bears have visited the village of Belushya Guba on the Novaya Zemlya islands in northern Russia over the past few months, The Washington Post reports. The bears are getting into homes and office buildings, prompting officials to declare a state of emergency. Videos uncovered by The Guardian that purport to show the bear invasion show them chowing down at the local dump. It’s exactly the behavior experts expect given the easy access to garbage in the town and the shrinking sea ice where polar bears would typically hunt. It’s a preview of what’s to come as climate change continues to reduce sea ice and people keep expanding into a thawing Arctic. To be clear, polar bear … [Read more...] about Why polar bears invaded a Russian village
Much of the deep sea has never been explored close-up by humans. Some submarines have plumbed its depths, but reaching the ocean bottom is a complicated and expensive journey, challenging because the seabed lies under more than three miles of water, which exerts huge amounts of pressure. “We know more about space than about the bottom of the oceans in our own planet, even though more than two-thirds of the surface of the Earth is covered by marine sediments,” said Olivier Sulpis, a researcher and doctoral student at McGill University’s department of earth and planetary sciences.Thus, “we hear less about the effects of human activity at the seafloor than on corals, for instance, simply because coral bleaching sounds more appealing than mud dissolving at the bottom of the sea,” he added. “When you think that before Google maps arrived, it took humans several centuries to map the continents, it’s easy to understand why exploring the deep sea is so … [Read more...] about As oceans grow more acidic, they’re eating away at their protective floors
'I told him to go' By Mike Moffitt, SFGATE Published 12:01 pm PDT, Thursday, August 2, 2018 Photo: Brian Melley / Associated Press Black bears should never be allowed in your kitchen.

A 95-year-old Vancouver Island, B.C., woman chased an "annoying" black bear out of her kitchen — twice in the same day. Anna Stady told CTV News she was watching television in her Union Bay home when she heard noises coming from her kitchen. She went to check out the disturbance and came upon a large black bear rooting around for something to eat. "I was annoyed," she said. "I told him to go and then he just went about halfway to the backyard and I said 'No! Go home!'" The bear finally got the message and left. But it wasn't long before it returned. Stady found him again in … [Read more...] about ‘Annoyed’ woman, 95, shoos bear out of her kitchen — twice in one day
SEATTLE, July 12 (Reuters) - Jeff Bezos' rocket company plans to charge passengers about $200,000 to $300,000 for its first trips into space next year, two people familiar with its plans told Reuters.Potential customers and the aerospace industry have been eager to learn the cost of a ticket on Blue Origin's New Shepard space vehicle, to find out if it is affordable and whether the company can generate enough demand to make a profit on space tourism.Executives at the company, started by Amazon.com Inc founder Bezos in 2000, told a business conference last month they planned test flights with passengers on the New Shepard soon, and to start selling tickets next year.The company, based about 20 miles (32 km) south of Seattle, has made public the general design of the vehicle - comprising a launch rocket and detachable passenger capsule - but has been tight-lipped on production status and ticket prices.Blue Origin representatives did not respond to requests for comment on its programs and … [Read more...] about Sources reveal what Jeff Bezos plans to charge for space rides
