Spatial and temporal variations in basal melting at Nivlisen ice shelf, East Antarctica, derived from phase-sensitive radars

first_imgThinning rates of ice shelves vary widely around Antarctica, and basal melting is a major component of ice shelf mass loss. In this study, we present records of basal melting at a unique spatial and temporal resolution for East Antarctica, derived from autonomous phase-sensitive radars. These records show spatial and temporal variations of basal melting in 2017 and 2018 at Nivlisen, an ice shelf in central Dronning Maud Land. The annually averaged basal melt rates are in general moderate (∼0.8 m yr−1). Radar profiling of the ice shelf shows variable ice thickness from smooth beds to basal crevasses and channels. The highest basal melt rates (3.9 m yr−1) were observed close to a grounded feature near the ice shelf front. Daily time-varying measurements reveal a seasonal melt signal 4 km from the ice shelf front, at an ice draft of 130 m, where the highest daily basal melt rates occurred in summer (up to 5.6 m yr−1). In comparison with wind, air temperatures, and sea ice cover from reanalysis and satellite data, the seasonality in basal melt rates indicates that summer-warmed ocean surface water was pushed by wind beneath the ice shelf front. We observed a different melt regime 35 km into the ice shelf cavity, at an ice draft of 280 m, with considerably lower basal melt rates (annual average of 0.4 m yr−1) and no seasonality. We conclude that warm deep-ocean water at present has a limited effect on the basal melting of Nivlisen. On the other hand, a warming in surface waters, as a result of diminishing sea ice cover, has the potential to increase basal melting near the ice shelf front. Continuous in situ monitoring of Antarctic ice shelves is needed to understand the complex mechanisms involved in ice shelf–ocean interactions.last_img read more

Royal Navy, Auxiliary Fleet to receive Kelvin Hughes radars

first_img Approximately 60 Royal Navy and Royal Fleet Auxiliary ships, submarines and shore facilities will be fitted with Kelvin Hughes’ SharpEye™ radars.The company said it would supply the radars in association with Lockheed Martin Integrated Systems UK who have signed a £44 million contract with the Ministry of Defence (MOD).The systems will be fitted on Royal Navy’s Type 23 frigates, Hunt and Sandown class Mine Counter Measure Vessels, Royal Fleet Auxiliary support vessels and fast patrol boats as well as the Astute, Trafalgar and Vanguard class submarines.Kelvin Hughes said the contract with Lockheed Martin also included options for the introduction of navigation radar systems for future Royal Navy platforms such as the Queen Elizabeth carriers, the Type 26 Global Combat Ship and Successor submarines.Rohan Dearlove, Kelvin Hughes’ UK Maritime Sales Director, commented: “The provision of SharpEye™ under this contract supports the MOD’s desire for technological convergence, with similar radars being already in service with the Fleet and selected for MOD programmes such as the Tide class tankers and the new OPVs.”Dearlove added: “We are confident that MOD will decide to exercise options within the NRP contract which facilitate the roll out of SharpEye across additional platforms. This would extend the operational benefits associated with technological convergence to the newer vessels types such as Type 45, the two new carriers and future Type 26 and general purposes frigates.”Kelvin Hughes’ Chief Executive, Russell Gould, added: “SharpEye™ systems are currently being deployed by 27 of the world’s navies and this major new project is a further vote of confidence in the superior performance and reliability of Kelvin Hughes SharpEye™ technology.” Royal Navy, Auxiliary Fleet to receive Kelvin Hughes radars View post tag: Royal Navy March 21, 2016 Share this article Authorities View post tag: Kelvin Hughes Back to overview,Home naval-today Royal Navy, Auxiliary Fleet to receive Kelvin Hughes radars View post tag: Royal Fleet Auxiliarylast_img read more

EPA Recognizes Electronics Manufacturers, Retailers and Brand Owners for Making Electronics More Sustainable

first_imgTomorrow, the U.S. Environmental Protection Agency (EPA) will recognize leading electronics manufacturers, retailers, and brand owners for their significant contributions in diverting electronics from landfills. The winners will be honored during an event at the 2017 Consumer Electronics Show (CES) in Las Vegas.“The successful practices spearheaded by our Sustainable Materials Management (SMM) Electronics Challenge participants are inspiring examples of how other manufacturers, retailers and brand owners throughout various industries can make their products more sustainable throughout their life cycles,” said Mathy Stanislaus, Assistant Administrator for EPA’s Office of Land and Emergency Management. “I am proud to recognize the awardees and all SMM Electronics Challenge participants who are leading the industry in creating innovative ways to meld environmental responsibilities with sound business practices, which are necessary for future growth.”“CTA is honored to host EPA at CES 2017 and recognize the winners of the annual SMM Awards Challenge,” said Walter Alcorn, vice president, Environmental Affairs and Industry Sustainability, Consumer Technology Association. “These awards help demonstrate our industry’s focus on advancing sustainable operations to reduce e-waste and our industry’s overall environmental impact. In fact, through the consumer tech industry’s leadership, EPA research shows electronics recycling has increased more than that of any other product stream in the U.S.”Electronic products are a global economic driver, with supply chains reaching around the world. By designing with the environment in mind and through a lifecycle lens, the product can be made to be more readily repairable and reusable, while toxic materials can be designed out of the product, which extends product life and facilitates recycling.In the spirit of innovation, the EPA is unveiling a new award this year: The Cutting Edge Award. This award promotes bold ideas that have the potential to make a huge impact on the future of sustainable electronics management across a product’s full supply chain. It is designed to encourage life cycle thinking while creating ambitious and new ideas that have the potential to be game changers in addressing sustainability in electronics.Leaders from Best Buy (Gold Tier Award), Dell (Gold Tier), LG Electronics (Gold Tier), Samsung (Gold Tier), Sony (Bronze Tier), Sprint (Gold Tier), Staples (Gold Tier), and VIZIO (Bronze Tier) will gather at CES to celebrate their environmental achievements, which include diverting more than 256,000 tons of used electronics from landfills in 2015 – equivalent to taking 129,000 passenger vehicles off of the road for one year. Of the used electronics collected, almost all (more than 99.9 percent) were sent to third-party-certified recyclers, which helps to ensure that used electronics are handled in a manner that protects human health and the environment.EPA is also honoring Dell, Staples and Samsung as the SMM Electronics Challenge Champion Award winners for exemplifying exceptional leadership and innovation in the sustainable management of electronics. These three companies serve as examples in demonstrating significant environmental, social, and economic outcomes for their organizations and the public that go above and beyond the requirements of the SMM Electronics Challenge.Dell is receiving an award for its pioneering use of post-industrial recycled carbon filled polycarbonate in the Latitude E7450 laptop.Staples is receiving an award for its “Make More Happen” initiative, an outreach and public education campaign that has provided information on Staples’ Technology Recycling Program to more than 6 million people.Samsung is receiving the inaugural Cutting Edge Award for its Cadmium-free Quantum Dot ultra-high-definition televisions.Mr. Stanislaus will also introduce a CES panel, “Can Sustainability Payoff in Tech?” The panel will bring together policymakers, researchers and leaders in the industry to discuss sustainability issues.Both the SMM Awards and the sustainability panel are open press.WHEN and WHERE:Awards Ceremony10:00 -10:30 a.m. PST – Saturday, January 7, 2017LVCC, Grand Lobby Consumer Technology Association Center StageTech East Las Vegas Convention Center3150 Paradise RoadLas Vegas, NV 89109Panel Discussion1:00 – 2:00 p.m. PST – Saturday, January 7, 2017North Hall N254 Las Vegas Convention Center3150 Paradise RoadLas Vegas, NV 89109 FacebookTwitterCopy LinkEmailSharelast_img read more

Press release: PM meeting with New Zealand Prime Minister: 18 April 2018

first_imgA Downing Street spokesperson said: The Prime Minister held a bilateral meeting with the New Zealand Prime Minister Jacinda Ardern at Downing Street earlier today. They agreed the bond between the UK and New Zealand was unique and enduring, based on friendship and shared values, and underpinned by strong security, prosperity and people-to-people links. The Prime Minister said New Zealand was an indispensable partner for the UK, noting the relationship has always been important, but is arguably even more vital today, given our shared commitment to free trade and protecting the rules-based international system. The Prime Minister thanked Prime Minister Ardern for New Zealand’s support over the attack against the Assad regime, and following the chemical nerve agent attack in Salisbury. They agreed it was essential to reassert the international norm against chemical weapons use. They agreed that part of reinvigorating the Commonwealth was about fostering more intra-Commonwealth support, and to explore the possibility of working together on development assistance in the Pacific region. They also discussed the bilateral trade and investment relationship, agreeing that UK-New Zealand trade working group discussions were progressing well and confirming our shared ambition to form a new bilateral UK-New Zealand Free Trade Agreement once we have left the EU. They welcomed the approach agreed at the March European Council to provide continuity during the implementation period for international agreements, which could be swiftly transitioned into new bilateral agreements once the implementation period ends.last_img read more

From spreadsheets to city streets

first_img Related Two Harvard efforts are helping craft policy before the shift gains speed In two recently released papers, a pair of scholars affiliated with Harvard Kennedy School’s Ash Center for Democratic Governance and Innovation take a close look at how urban leaders are grappling with the quick pace of technological and regulatory change in America’s cities today. In “Reforming Mobility Management: Rethinking the Regulatory Framework,” Stephen Goldsmith, Daniel Paul Professor of the Practice of Government at Harvard Kennedy School, lays out a new model for how cities can regulate ride-sharing services. Craig Campbell, a fellow with the Ash Center’s Innovations in Government Program and the assistant director for policy and operations in the New York City Mayor’s Office of Data Analytics, in “Replicating Urban Analytics Use Cases,” tackles the question of how cities can adopt and adapt successful civic data analytics programs from peer municipalities.New Urban Mobility ManagementWith the proliferation of ride-sharing services across the country, concerns are arising about how the ever-growing number of Uber and Lyft trips are impacting traffic congestion. Last year, mayors of large cities cited traffic as a top three concern mentioned by citizens. Yet these ride-sharing services have found a ready customer base in urban dwellers frustrated by existing transportation options.To alleviate the tension surrounding urban mobility, cities, writes Goldsmith in his latest paper, “must embrace a new role of planner, coordinator, and facilitator of a distributed system of integrated [transportation] providers.” In his new paper, Goldsmith calls on cities to acknowledge that ride-sharing services can greatly increase access to and availability of urban mobility options and suggests integrating ride-sharing into a more unified transportation system. He advocates for a “light touch” regulatory regime for ride-sharing that employs curbside pricing to create a market-based usage model to wring maximum efficiency from congested urban roadways and curbsides. “By charging for time stopped at the curb, the system incentivizes quick turnover and efficient pickups to avoid the negative effects of vehicles lingering at curbside,” Goldsmith writes.Replicating City SuccessLike nearly every other facet of life, technology has upended city hall operations. Integrating the use of data into municipal functions has city leaders both excited and frustrated. As cities grapple with new models for data-driven decision making, they are increasingly turning to each other for guidance and examples.“How should a data-processing solution in Louisville, or a problem-solving methodology in New York City, get iterated in other cities?” asks Campbell in his paper. Campbell unpacks the theoretical and practical considerations for replicating data analytics use cases from city to city. His specific recommendations include:Look internally for replication opportunitiesAvoid pursuing a project-to-project technological savvinessConnect analytics professions with communities of practice in transportation, economic development, policing, etc.Do not simply replicate specific tools, but “replicate processes for problem-solving”Discuss failureWhile there is much to be learned from peer cities, “successfully connecting use case replication to a city’s long-term analytics ‘journey’ requires a deep investment in data and a sustained appetite for innovation — the foundational layers of problem-solving that cannot be copied,” Campbell concludes.

Brazilian Navy Acquires Most Modern Science Ship in its Fleet

first_img“For example, if there were an oil spill, we would be able to better understand the behavior of the waters in that area, in what direction the waves would travel, etc.,” Vice Adm. Pontes Lima explained. “What the country manages to demonstrate becomes part of its sovereign territory,” Vice Adm. Pontes Lima said. ”Research conducted by the Vital de Oliveira will undoubtedly contribute to expanding the zone of Brazil’s sovereignty at sea.” Testing sophisticated technology The seabed sampling tool operates at a depth of up to 8,000 meters (4,000 meters more than the ROV) and differs from the underwater robot because it’s launched at sea, from where it drops straight to the ocean floor, while the ROV navigates underwater. Still, the sampling tool has the advantage of penetrating up to 12 meters into the seabed subsoil, a capability that’s important in searching for petroleum or other mineral resources. Delivered to the Navy on July 23, the vessel is undergoing its final phase of testing and crew training in August and September before it’s ready to fulfill its mission: monitoring and preparing physical, chemical, biological, and environmental descriptions of ocean areas of strategic importance for the exploration of natural resources. The Vital de Oliveira’s technological capabilities will help maximize maritime economic opportunities. The ship has two other two laboratories – a “dry lab,” which has computers and data-processing resources, and a “wet lab,” which is equipped to analyze samples of sea water from the seabed and subsoil. The ninth ship in the Brazilian Navy’s Directorate of Hydrography and Navigation fleet, the Vital de Oliveira is noteworthy for its size – it’s 78 meters long with room for 90 crew members and 40 researchers – and for its equipment, as it has 28 devices or systems, well above the four-to-nine on most of the fleet’s other ships. Boosting the economy Naval authorities and scientists have great expectations for the ROV, an underwater robot that can reach a depth of 4,000 meters and features a video camera, sonar, and pincers, which enable it to collect materials from the seabed with great precision. The Vital de Oliveira is also outfitted with a laboratory exclusively for the robot, the space of which serves as a command module where the robot is controlled and where service members can view images it captures in real time. The Vital de Oliveira’s management committee, responsible for drafting the vessel’s plan of work, hasn’t determined the priority studies for the ship’s first scientific mission, which is scheduled for October. The committee will be comprised of four participants from the agencies in the agreement authorizing the ship’s acquisition: the Ministry of Defense; the Ministry of Science, Technology, and Innovation; state oil company Petrobras; and Brazilian mining company Vale. center_img This collection of marine data will be important for civilian purposes – such as searching for oil – and for Military use, like “creating more complete nautical maps used to improve navigational security and to support Naval operations,” said Vice Admiral Antonio Reginaldo Pontes Lima, Jr., director of the Navy’s Directorate of Hydrography and Navigation. Researchers have already used the plankton net to collect phytoplankton and zooplankton – organisms analyzed in oceanographic biological research to help authorities identify the richest areas for fishing. The wave measurement devices calculate the height, periods, and direction of waves and will be used to identify water behaviors. Before the Vital de Oliveira becomes active, Naval officials must complete testing on four technologically advanced devices: the Remotely Operated Vehicle (ROV); a seabed sampling tool; a sound velocity in-water profiler; and a satellite communications system. Everything will be tested by the crew through the end of September while the Vital de Oliveira navigates Rio de Janeiro’s coast. Boosting the Navy’s scientific capacity By Dialogo September 07, 2015 LET’S ADVANCE AGAINST THE WIND AND SEA. BRAZIL IS THE BEST SOUTH AMERICAN COUNTRY AND THEIR ARMED FORCES ARE EXCELLENT, THE BEST IN SOUTH AMERICA. According to the United Nations Convention on the Law of the Sea, all coastal states have rights over an exclusive economic zone, which encompasses the waters superjacent (lying above or upon) to the seabed and its subsoil up to 200 nautical miles (approximately 370 kilometers). The convention also allows states the right to exploit the seabed and its subsoil along the extent of the area, provided the nation uses data to prove its continental shelf extends more than 200 nautical miles. Almost half of the equipment on the new ship – like the underwater robot, the seabed sampling tool, the plankton net, and the wave measurement device – are rare in the Navy’s science fleet because they aren’t routinely used by the Hydrography and Navigation Directorate, or were never before available. Underwater robots, a plankton net, and a deep-sea scanner are some of the equipment that make the Hydro-Oceanographic Research Ship, Vital de Oliveira, the most modern of Brazil’s science ships. The name Vital de Oliveira was chosen to christen the science ship in honor of Cmdr. Manuel Antônio Vital de Oliveira, who perished in the Paraguayan War in 1867. However, his feats in hydrography were recognized with awards such as the French National Order of the Legion of Honor, the Portuguese Military Order of Christ, and the Italian Order of Saints Maurice and Lazarus.last_img read more
