The buttressing potential of ice shelves is modulated by changes in subshelf melting, in response to changing ocean conditions. We analyze the temporal variability in subshelf melting using an autonomous phase-sensitive radio-echo sounder near the grounding line of the Roi Baudouin Ice Shelf in East Antarctica. When combined with additional oceanographic evidence of seasonal variations in the stratification and the amplification of diurnal tides around the shelf break topography (Gunnerus Bank), the results suggest an intricate mechanism in which topographic waves control the seasonal melt rate variability near the grounding line. This mechanism has not been considered before and has the potential to enhance local melt rates without advecting different water masses. As topographic waves seem to strengthen in a stratified ocean, the freshening of Antarctic surface water, predicted by observations and models, is likely to increase future basal melting in this area. Plain Language Summary Ice shelves (or the floating parts of the Antarctic ice sheet) lose primarily mass through melting at their bottom in contact with the ocean. This thins them and makes them more vulnerable to potential collapse. To understand the processes governing such thinning, direct and long-time measurements are essential. Here we report on the first high-resolution time series of direct melt measurements on the Roi Baudouin Ice Shelf in Dronning Maud Land during 2016. We find that subshelf melt varies on both seasonal and daily time scales. Temporal variations stem from topographical ocean waves that originate on the continental shelf and transfer ocean properties without time delay within the ice shelf cavity. Therefore, seasonal variations highly depend on the presence/absence of sea ice in front of the ice shelf, which impact the strength of topographical waves. This mechanism is highly efficient at increasing the ice-ocean exchanges and may explain regional differences in ice shelf melt.

Buses are far more than a way of getting from A to B. They are a crucial tool in the fight against loneliness and it is good to see the industry taking steps to tackle isolation. This government is doing more than ever before to reduce emissions across all modes of transport and I’m delighted to see the bus industry putting itself at the forefront of this. Communities across the UK will benefit from greener journeys thanks to 263 new low emission buses, Minister Nusrat Ghani will announce today (Wednesday 6 February 2019). A £48 million investment from the Office for Low Emission Vehicles will fund new green vehicles and infrastructure to drive forward government plans to clean up the air in towns and cities. 263 new ultra-low emission buses will double numbers in the UK fleet Industry pledge to tackle loneliness through new community initiatives and innovative vehicle design funding for new buses and charging infrastructure will help meet low emission targets in the government’s Clean Air Strategy Speaking at the UK Bus Summit this morning, the minister will also announce a new partnership with Greener Journeys to reflect the pivotal role played by the bus industry in tackling loneliness and social isolation.The partnership will see companies across the sector pledge to do all they can to tackle loneliness, including through innovative vehicle design and initiatives to encourage bus passengers to talk to each other.Buses Minister Nusrat Ghani said: News desk enquiries Visit the Ultra-Low Emission Bus Scheme winning bidders interactive map. Media enquiries 020 7944 3021 Out of hours media enquiries 020 7944 4292 Nineteen successful bidders across England and Wales will receive funding to purchase new low emission buses and supporting infrastructure, such as charge points.Benefits of Ultra Low emission busesThis is the latest funding in a long line of investment designed to drive the uptake of zero emission vehicles, following the government’s £1.5 billion Road to Zero strategy published last year.In line with the Future of Mobility Grand Challenge – set out in the government’s modern Industrial Strategy – these measures chart a path for Britain to become a world leader in the zero-emission revolution, ensuring that the UK has cleaner air, a better environment and a stronger economy.But buses are not just about cleaning up the air in our towns and cities. As a key mode of transport for older and vulnerable people, buses play a vital role in facilitating social connections.The government also supports bus travel through a £250 million investment every year, as well as a further £1 billion for the free bus pass scheme, paving the way to a more sustainable future.On top of this, there have already been several promising schemes launched by the bus sector, including Go Ahead Group’s ‘Chatty Bus’ campaign, encouraging conversations between passengers, and ‘Hattie,’ a community bus from Stagecoach specifically designed to provide a friendly environment where people can chat to others.Claire Haigh, Chief Executive, Greener Journeys, said: The Prime Minister launched the government’s first loneliness strategy in October 2018, as a vital first step in a national mission to end loneliness in our lifetimes. Loneliness is one of the greatest public health challenges of our time and the strategy, which responds to the findings of the Jo Cox Commission, sets out a range of initiatives to help all age groups build connections. We’re delighted to be partnering with the government to tackle the epidemic of loneliness affecting millions of people in the UK. Research from Greener Journeys shows that a third of people in Britain go at least a day a week without speaking to anyone – not a friend, colleague or family member. Buses play a vital role in facilitating social connections among the most vulnerable people, who rely on them to take them to visit friends and family. It’s fantastic to see the industry come together to launch such a brilliant range of initiatives to address the problem of loneliness. Switchboard 0300 330 3000
The Centers for Disease Control and Prevention (CDC) may have underestimated the number of obese adults in the U.S. in its 2013 Obesity Prevalence Maps by at least 12 million because of reliance upon self-reported height and weight figures, according to a new study by researchers at Harvard T.H. Chan School of Public Health, Columbia University Mailman School of Public Health, and colleagues. The researchers upped the estimated number of obese adults in 2013 from about 69 million to 81 million of 240 million adults. Approximately 33 million of the 81 million were considered to have severe obesity, defined as a body mass index (BMI) of 35 or above.The study was published March 8, 2016 in PLOS ONE as part of the CHOICES Project, a research program to identify and prioritize cost-effective strategies to prevent childhood obesity. The CDC maps are updated annually and along with related data help drive state obesity prevention efforts and the allocation of federal obesity prevention resources.“Accurate estimates of state-level obesity are necessary to plan for resources to address this epidemic,” said Zach Ward, lead author and programmer/analyst in the Center for Health Decision Science at the Harvard T.H. Chan School of Public Health. “Our corrected state-level estimates provide decision makers with a more solid foundation of data on which to base obesity prevention policies.” Read Full Story
FacebookTwitterLinkedInEmailPrint分享New Haven Register:State utility regulators have given final approval of five long-term power purchase contracts that will provide Connecticut with 252 megawatts of renewable energy.The Connecticut Public Utilities Regulatory Authority approved the contracts late Wednesday. The 20-year contracts with Eversource Energy and United Illuminating include the state’s first-ever offshore wind power procurement as well as four fuel-cell projects. The projects approved by PURA will produce enough power to account for 4.6 percent of Connecticut’s annual power consumption.The so-called Revolution Wind project will produce 200 megawatts of electricity from a wind farm that will be built in federal waters about halfway between Montauk, N.Y., and Martha’s Vineyard. That’s enough electricity to power 100,000 Connecticut homes.Offshore construction of the Revolution Wind project will begin in 2022, It will begin operating a year later, according to officials with Orsted US Offshore Wind, which is building the project.Jeffrey Grybowski, co-chief executive officer of Orsted US Offshore Wind, said approval of the contracts for the project makes Connecticut “an important player in America’s offshore wind industry. We’re ready to make major investments in our local workforce and in the Port of New London to ramp up this project,” Grybowski said in a statement.More: Connecticut regulators approve contracts for renewable energy projects Connecticut regulators approve state’s first offshore wind project

It says more than 35 GW of capacity is either under construction or in advanced development across 31 states.Wind energy now stands at 96.4 GW of cumulative installed capacity, more than double what it was in 2010. AWEA says the United States now has enough installed wind energy to power more than 30 million homes. According to the report, wind energy now “reliably delivers” more than 20% of the electricity produced in six states: Iowa, Kansas, Maine, North Dakota, Oklahoma and South Dakota.[AWEA CEO Tom] Kiernan attributed the growth to corporate and industrial purchases of wind energy — 11.3 GW of clean wind energy because “Americans want it” — and utility purchase agreements.AWEA says if Texas were a country, it would rank fifth globally in wind energy capacity, with nearly 25 GW of installed capacity. Texas is home to about a quarter of the nation’s wind capacity, and the 7 GW of additional projects under construction or in advanced development is more wind than all but two other states have installed.More: AWEA: Another record-breaking year for wind industry AWEA sees ‘record amount’ of new wind capacity coming online in the next couple years
By Roberto López Dubois/Diálogo September 23, 2018 In July and August, the Panamanian National Border Service (SENAFRONT, in Spanish) seized more than 270 kilograms of cocaine in two operations carried out in the country’s east. During the operations, SENAFRONT’s Special Forces Group (AFFEE, in Spanish) neutralized a Colombian citizen, arrested another, and seized several weapons. AFFEE’s operations in Darién aim to secure territorial control in the jungle area known as the Darién Gap, which extends toward Colombia. The elite unit also seeks to put an end to drug smuggling, focusing operations against narcotraffickers who travel as backpackers through the dense, damp jungle. “Our main mission is to make every effort to prevent illicit substances from entering our country,” Major Oriel De Gracia, head of AFFEE, told Diálogo. “[And prevent] that they continue on to other countries in northern America.” Operation Navaja AFFEE started Operation Navaja on July 3rd, based on intelligence from the Colombian National Police’s Counternarcotics Directorate. The information pointed to backpackers carrying illicit substances, who may have crossed into Panamanian territory. With the information, AFFEE devised a mission to locate the group, detain its members, and seize the drugs. “The operational environment in Darién is very complex; it rains one moment, and the next it’s very sunny. [Units] work day and night.” said Maj. De Gracia. “They [the criminals] don’t rest either, and our units work nonstop until they fulfill the mission, as they are prepared, trained, and equipped for this kind of mission.” In mid-July, AFFEE officers found a group of backpackers in the Darién area of Alto Tuira. Units waited for the right time to catch them and then ordered them to stop. “With their knowledge of the terrain, they were able to determine where the suspects would pass through,” Maj. De Gracia said. “The suspects were ordered to stop, which they ignored, and instead opened fire on the units.” In the shooting, AFFEE units neutralized a Colombian national; the rest of the group was able to escape. As a result, authorities seized three AK-47 rifles and three loaders with ammunition. A few days later, the elite forces seized 11 bags of drugs inside a hideout in the same area. The bags, found with the support of canine units, contained 230 kg of cocaine worth more than $7 million in the international market. “Backpackers carry the drug from Colombian communities located on the border to a storage point,” Commissioner José Samaniego, commander of SENAFRONT’s First Eastern Brigade, told Diálogo. “[Criminals] hide the drug to then transport it to markets outside of Panama.” Operation Escudo At the end of August, AFFEE units and backpackers exchanged fire near the Darién village of Guna de Wargandí. The armed clashes, part of Operation Escudo, resulted in the seizure of 43 drug packages worth $1 million, several weapons, and one person captured. “Lately, we’ve had more incidences of arm bearing,” Commissioner Samaniego said. “In the past, we would see two or three armed individuals, but now there are more armed people.” In the first encounter, officers confronted a group of four people, who escaped and left a backpack with about 20 kg of cocaine, an M-4 rifle, and a loader with ammunition. In the second, authorities detained Neider Palacios Pino, a Colombian national who escaped from La Joyita Detention Center in the Panamanian province of Pacora in 2015. Authorities also seized more than 20 kg of cocaine, an M-4 rifle, two loaders, 82 rounds of ammunition, a GPS, and two portable radios. For Panama’s wellbeing AFFEE’s four companies—a total of 400 units—are committed to protecting Panamanian borders. According to Commissioner Eric Estrada, general director of SENAFRONT, the Darién strategy benefits from several components. The information exchange with Colombia, based on binational agreements such as the Colombia-Panama Binational Border Commission, in effect since 2000, strengthens the fight against narcotrafficking. “One [of the components] is intelligence, which obviously attempts to attack the criminal structure as such, and an operational component that seeks to have an active presence,” said Commissioner Estrada. “A very important component is the integrated action that seeks to get to know the human environment of our area of operations, its needs, demands, and expectations, which allows both [the Panamanian and Colombian] authorities to come in and combat the problem.” So far in 2018, AFFEE seized almost 340 kg of cocaine in operations against cocaine backpackers in the Darién region. Meanwhile, SENAFRONT seized 3,559 kg of cocaine between January and August 2018. “Special forces commands are ready and willing to contribute to Panama’s wellbeing,” Maj. De Gracia concluded. “We work day and night, tirelessly, with hope and faith in our Lord for his guidance and care in all our operations.”
CUNA followed its push for a 6-month extension of the Oct. 3 effective date for changes to the Military Lending Act (MLA) rule this week with a joint letter sent to Federal Financial Institutions Examination Council (FFIEC) member agencies requesting the agencies to delay examination of the new rule. FFIEC member agencies include the NCUA and the Consumer Financial Protection Bureau (CFPB).“Given the delays associated with clarifying the rule and setting up systems to ascertain military status–and the severe penalties for MLA violations–we urge the agencies to provide express assurances that MLA examinations will be limited to inquiries about the status of preparations to comply and that examiners will postpone transactional testing for compliance until after March 3, 2017—giving industry six months to implement and test its MLA compliance systems,” the letter reads.“We believe that this approach is not only fair and practical, but will help to ensure that military personnel, their spouses and dependents continue to have access to depository institution credit products they need and value.”The Department of Defense (DOD) finalized changes to the MLA rule in July 2015, adding protections on loans made to covered servicemembers. Since then, CUNA has had a number of meetings with the DOD to share industry concerns and push for guidance. continue reading » ShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr
