Early East Antarctic Ice Sheet growth recorded in the landscape of the Gamburtsev Subglacial Mountains

first_imgThe Gamburtsev Subglacial Mountains are regarded as a key nucleation site for the Antarctic Ice Sheet and they retain a unique long-term record of pre-glacial and early glacial landscape evolution. Here, we use a range of morphometric analyses to constrain the nature of early glaciation and subsequent ice sheet evolution in the interior of East Antarctica, using a new digital elevation model of the Gamburtsev Subglacial Mountains, derived from an extensive airborne radar survey. We find that an inherited fluvial landscape confirms the existence of the Gamburtsev Subglacial Mountains prior to the onset of glaciation at the Eocene–Oligocene climate boundary (ca. 34 Ma). Features characteristic of glaciation, at a range of scales, are evident across the mountains. High elevation alpine valley heads, akin to cirques, identified throughout the mountains, are interpreted as evidence for early phases of glaciation in East Antarctica. The equilibrium line altitudes associated with these features, combined with information from fossil plant assemblages, suggest that they formed at, or prior to, 34 Ma. It cannot be ruled out that they may have been eroded by ephemeral ice between the Late Cretaceous and the Eocene (100–34 Ma). Hanging valleys, overdeepenings, truncated spurs and steep-sided, linear valley networks are indicative of a more widespread alpine glaciation in this region. These features represent ice growth at, or before, 33.7 Ma and provide a minimum estimate for the scale of the East Antarctic Ice Sheet between ca. 34 and 14 Ma, when dynamic fluctuations in ice extent are recorded at the coast of Antarctica. The implications are that the early East Antarctic Ice Sheet grew rapidly and developed a cold-based core that preserved the alpine landscape. The patterns of landscape evolution identified provide the earliest evidence for the development of the East Antarctic Ice Sheet and can be used to test coupled ice–climate evolution models.last_img read more

Shaping problem-solvers

first_img“The existing system in many developing countries is not working for the masses, so almost by definition you need entrepreneurship,” Tarun Khanna said of the social and economic issues facing India, Pakistan, Bangladesh, and other nations of South Asia.Khanna, the Jorge Paulo Lemann Professor at Harvard Business School and the director of Harvard’s South Asia Institute, leads the Gen Ed course “Contemporary South Asia: Entrepreneurial Solutions to Intractable Social and Economic Problems.” He was speaking just outside Sever 113, where his students were working furiously on plans for improving maternal mortality in one of two places — India’s state of Uttar Pradesh or the Pakistani state of Punjab. A few minutes earlier, they had been presented with two scenarios and a sheet of relevant data, and then given half an hour to brainstorm solutions.The scenarios weren’t Khanna’s, but those of Sue J. Goldie, the Roger Irving Lee Professor of Public Health and the director of the Global Health Education and Learning Incubator at Harvard. Goldie is one of a handful of co-instructors who have joined Khanna this semester to lend their expertise in key fields.While Goldie has addressed health issues, the Graduate School of Design’s Rahul Mehrotra has discussed challenges stemming from urbanism; Conor Walsh, an assistant professor of mechanical and biomedical engineering from the School of Engineering and Applied Sciences, has looked at technology; and Parimal Patil, a professor of religion and Indian philosophy and the chair of the Department of South Asian Studies, is in the middle of four weeks of teaching about solutions enabled by the arts and humanities.“I think it exposes students to wonderfully different voices,” Mehrotra, the chair of the Department of Urban Planning and Design, said of the interdisciplinary approach. “These are critical issues and linked to each other. You can’t talk about public health without talking about urbanization. … One critical question that [recurs] is the lack of capacity of government and other entities to respond.”Khanna and officials at the South Asia Institute say that the cross-faculty approach of the course reflects the mission of the institute itself.The South Asia Institute supports Harvard scholarship in the region and fosters collaboration with scholars based there, according to Executive Director Meena Hewett. The institute, which also explores the region for lessons of broader global relevance, has supported the course and publicized it to students, Hewett said.The development of the four-year-old course has been part of the institute’s broader growth, Khanna said, and filled a gap, shaping a University-wide approach to teaching about South Asia.After a period of tinkering, the course has hit its stride, he said.“It’s become a real test bed of experimentation.”One of the key concepts Khanna wants students to take away is an understanding that though data collection is a crucial part of problem solving, it is not sufficient in itself. Students have to be willing to act on less-than-perfect information, trust themselves and their local partners, and be ready to make adjustments.“In real life, as entrepreneurs, you don’t have enough data, but you have to act,” Khanna said. “Where is the ‘good enough to act’ point?”The course is offered for credit by several of Harvard’s Schools, and draws 60 to 65 students. This year, 25 of the 60 students are undergrads, with the others attached to the Law School, the Kennedy School, the Graduate School of Education, the Business School, the School of Public Health, the Graduate School of Arts and Sciences, and even Tufts University.In her four-week portion of the class, Goldie sought to give students background on the region’s health scene before drilling down to nation-specific challenges. She directed students’ attention not to memorizing statistics, but to methods of investigation.Their job as budding health entrepreneurs, Goldie told students during one class, is to “scan that horizon” for opportunities, looking for institutional voids — a concept coined in 1997 by Khanna and Ross Graham Walker Professor of Business Administration Krishna Palepu — in areas where partner organizations and some infrastructure provide a platform for growth.“You’re a health entrepreneur,” Goldie urged the students. “You’re action-oriented, you want to do something.”Partnership, Goldie said later, is key in health settings. She cautioned against narrow thinking and hubris, saying that local partners can provide both resources and the sort of front-line knowledge that often turns out to be decisive.The course’s health module has been successful enough that an online version has been developed and is being offered via Harvard’s open online course platform, HarvardX. It kicked off Oct. 30 and has more than 10,000 participants.Back in the bricks-and-mortar classroom, students are required to complete a semester-long project that proposes an entrepreneurial solution to a specific problem and builds a business plan to execute it. Students work in teams that often include peers from different Schools, bringing a range of perspectives to bear. Cherie Ramirez, a staff leader at the Global Health Education and Learning Incubator who has supported Goldie’s health modules for the course, said that the practical focus is a way to boost learning.“It’s great to have knowledge for its own sake, but you’re [learning as you] try to figure out how to build a business in the basement.”For Rabiya Mahmood, who is collaborating with two fellow Kennedy School students on her project, the course has provided a chance to explore ways to empower women in Pakistan, work she wants to continue after graduating. For her project, Mahmood is developing a Web-based tool to connect consumers in developed nations with Pakistani tailors.Mahmood said she has enjoyed the course’s interdisciplinary nature, which has given her a better idea of challenges in important areas.“It was great to understand the whole health care system,” Mahmood said. “I’m learning a lot.”Zeenia Framroze, a Harvard College senior from Adams House, ranked the course among her favorites. The focus on the problem-solving aspects of entrepreneurship has resonated with her.“It’s not just something to make money. That’s important to me and to other people taking the class.”last_img read more

IOU upheaval, push for more renewables moves to co-op arena

first_imgIOU upheaval, push for more renewables moves to co-op arena FacebookTwitterLinkedInEmailPrint分享The Gazette (Colorado Springs):Luis Reyes drove up to Durango from Taos, N.M., on a sunny April day in 2017 to tell folks how the Kit Carson Electric Cooperative, which he heads, left its interstate wholesale power provider and struck out on its own — and the room where he spoke at Durango’s Strater Hotel was packed.Kit Carson had paid $37 million to get out of its long-term contract with the Westminster-based Tri-State Generation and Transmission Association, which serves 43 electric cooperatives in four states, including 18 in Colorado.Several co-ops have complained about what they see as Tri-State’s high power costs, limits on developing local renewable energy and the loss of dollars sent out of town to buy electricity.Since Reyes’ talk, the Durango-based La Plata Electric Association has begun to explore its options, and the Delta-Montrose Electric Association is in separation talks with Tri-State. On the Front Range, large co-ops, such as Brighton-based United Power and Fort Collins-based Poudre Valley Rural Electric Association, are pressing for more local renewable generation.“When Kit Carson left last year, the lightbulb went on at the other 42 co-ops,” said Jerry Marizza, new energy program coordinator for United Power.This turmoil is born of rapid changes in the utility industry as power prices are falling due to cheap generation powered by natural gas, wind and solar and growing demands from consumers for homegrown renewable energy.Many co-ops, however, chafe at Tri-State’s 7.5 cents a kilowatt-hour charge when the going Western wholesale price is around 3.1 cents a kilowatt-hour, according to energy wholesaler Guzman Energy.“Tri-State is changing,” Marizza said. “It just isn’t changing fast enough.”More: Colorado rural electric cooperatives look at cutting the cordlast_img read more

Construction begins at hybrid wind, battery storage project in Australia

first_imgConstruction begins at hybrid wind, battery storage project in Australia FacebookTwitterLinkedInEmailPrint分享Renew Economy:The first of 56 turbines that will make up the nearly 200MW wind power component of Neoen’s Bulgana Green Power Hub is being installed, marking a new milestone for the ground-breaking hybrid renewables and battery storage project in Victoria.The project, which broke ground at the site of an old gold mine in Stawell in May last year, will deliver 100 per cent renewable energy to what will be the country’s biggest vegetable glasshouse, owned by Nectar Farms.In a statement on Wednesday, the Australian branch of French renewables developer Neoen said the first wind turbine was on the way up, while construction across the wider site continued to build momentum.“The integrated wind and battery storage facility continues to create hundreds of local jobs and is well on its way to meeting the targeted delivery date of August 2019,” said Neon Australia managing director Franck Woitiez. “Upon completion, the $A350 million facility will generate over 740,000MWh of emission-free, clean, competitive renewable energy per annum for the Stawell region and wider Victoria.”In comments to RE back in May of 2018, Neoen’s Woitiez said that project’s like the Green Power Hub served to demonstrate that the clean energy transition was well underway, and that coal was “a thing of the past.”The hydroponic greenhouse will take around 15 per cent of the output of the wind farm, and its needs will be backed up by a 20MW/34MWh Tesla battery storage facility.More: First turbine goes up at Neoen’s wind and battery hub in Victorialast_img read more

Brazilian Navy Installs Monitoring System to Fight Organized Crime

first_imgBy Andréa Barretto/Diálogo September 14, 2018 The Brazilian Navy (MB, in Portuguese) is in the midst of a project in Guanabara Bay that follows vessels as they reach Rio de Janeiro’s eastern zone, as well as 14 municipalities in the state of the same name, in real time. Rio de Janeiro’s status as one of the largest centers of Brazilian organized crime, led to the project’s launch. The area is a point of entry and departure for weapons and drugs, and is center stage for other crimes. Illegal goods are smuggled via land, air, and water. “By the end of 2018, the Navy hopes to complete installation of fixed sensors and cameras that form the monitoring and control system,” said MB Commander Rodrigo Pinheiro Padilha of the Naval Operations Command’s Systems Division. About 70 percent of the system, including radars, is ready. Authorities set up the equipment at strategic points along the bay’s entrance and surrounding areas. Four command centers, headquartered in different MB units throughout Rio de Janeiro, operate the equipment remotely. The setup, according to Cmdr. Padilha, allows for control and identification of suspicious activities aboard large and small ships that mostly travel at night to transport illegal goods and serve as an escape means for criminals. The Guanabara Bay monitoring project started in 2015. Authorities used the system for security during the 2016 Olympic Games. The experience in Rio de Janeiro serves as a pilot project for a much broader program, the Blue Amazon Management System (SisGAAz, in Portuguese) that aims to protect mineral resources and fishing areas within Brazil’s maritime territory. The region, known as Blue Amazon, consists of about 4.5 million square kilometers. Material and human resources SisGAAz’s initial stage includes completion of the technological operational structure at Guanabara Bay, and agreements to exchange information with public security agencies. The goal is to provide concrete data to military commands and civil institutions to improve strategies against criminal actions that use maritime routes. In late July 2018, in an operation with MB’s support, officers from the Federal Police’s Narcotics Enforcement Bureau located and seized 336 kilograms of cocaine inside a fishing boat. Authorities arrested three people pretending to be fishermen. “[Criminals] brought in the illegal goods via land. The gang typically receives goods in São Paulo, and transfers them to Rio using fishing boats,” said Carlos Eduardo Thomé, the officer who conducted the investigation leading to the drug seizure. “Interoperability is the pilot project’s keyword,” Cmdr. Padilha said, adding that MB’s research and technology teams developed the system. The approach enables the integration and operation of monitoring equipment of the Navy and other information tools intelligence and security agencies, such as the Federal Police and the department of Federal Revenue, use. “The project’s goal is to optimize the use of security forces, hence the development of IT support,” said Cmdr. Padilha. Currently, MB monitors Guanabara Bay through the Marine Corps General Command, the First Naval District Command, and the Rio de Janeiro Coast Guard, among other military units. Members of the Combat Divers Group also participate. Known as amphibious combatants, the service members are trained to approach ships and take action in situations when the crew under investigation shows resistance. Guaranteed additional security Resources available to service members mobilized in the war on crime at Guanabara Bay increased with the addition of a new speedboat in July 2018. The DGS 888 Raptor vessel is armored, fast, and has broad maneuvering capacity. According to MB Commander Ataíde de Melo, of the Naval Operations Command’s District Resources Division, the vessel manufacturer customized it to MB’s needs. “The company customized the existing DGS 888 Raptor model by creating an extended armored cabin for a small crew of up to six persons, guaranteeing more security for the crew during operations.” The Fist Naval District currently uses the speedboat. MB purchased two additional boats of the same model that will be delivered in 2018.last_img read more

Brazilian Armed Forces Conduct Joint Border Operation

first_imgBy Taciana Moury/Diálogo December 05, 2018 The border area along the Brazilian states of Mato Grosso, Mato Grosso do Sul, Paraná, and Santa Catarina served as the staging ground for security operation Ágata Graal, September 24-28, 2018. The initiative sought to curb drug trafficking, smuggling, and other illegal transnational activities along the 3,500-kilometer border with Bolivia, Paraguay, and Argentina. Operation Ágata is of a continuous nature and is carried out throughout the year in different border regions. The initiative projects preventive operations along the border via air, land, and river patrols. Service members set up checkpoints at river channels and main roads, conduct airstrip and port surveillance, and search vessels, motor vehicles, people, and aircraft. The objective is to step up government’s presence and integrate the activities of the Armed Forces with other federal, state, and municipal agencies responsible for the region’s security. Operation Ágata Graal, a name it acquired in the latest 2018 edition, was unprecedented due to the joint effort with the Brazilian Navy (MB, in Portuguese), Army (EB, in Portuguese), and Air Force (FAB, in Portuguese). Ágata Graal’s headquarters was setup in the city of Cascavel, in Paraná state, in the heart of the border area. There, service members patrolled air, land, and rivers simultaneously. FAB also coordinated aerial support from Aerospace Operations Command in Brasília. According to MB Admiral Ademir Sobrinho, head of the Armed Forces Joint Chief of Staff, previous operations had simpler formats and were developed quickly and more suddenly. “The joint work was limited to a strategic and operational structure, and when it was time for the tactical part, each force would operate separately,” Adm. Ademir said. Public security agencies such as the Federal Police, the Federal Highway Police (PRF, in Portuguese), the Brazilian Internal Revenue Service, and the military police from the states of Paraná and Mato Grosso do Sul took part in the interagency operations. A total of 3,000 service members and civilians, about 40 aircraft, and 1,000 different armored vehicles and boats participated. According to FAB Lieutenant General Ricardo Cesar Mangrich, commander of Ágata Graal, the biggest challenge was to assemble a structure to cover such an extensive and diversified border. “We had Lake Itaipu, at the border with Paraguay, where shores allow for the construction of paths used to board small boats that can carry illegal goods,” Lt. Gen. Mangrich told Diálogo. “We also had the Paraná-Tietê waterway, between Brazil’s southern and southwestern regions, which serve as a gateway into the country, near the state of São Paulo, a highly developed region. Lastly, the dry and complex border of Mato Grosso do Sul, with small roads every 200 meters, made control very difficult.” Joint task forces A general staff consisting of 40 officers from the three branches coordinated operations of the joint task forces created to patrol each area. The objective was to advise the commander according to the characteristics of each branch to optimize the use of available resources. “We used armored vehicles, subunits of EB’s motorized cavalry, FAB aircraft, and other resources,” said Lt. Gen. Mangrich. “The Joint Chief of Staff’s advice was essential to ensure interoperability, and avoid friendly fire from our service members operating side by side on the ground.” Service members conducted Ágata Graal’s operations at night to ensure the element of surprise, since these were not covert. “The troop got to the point where the opponent could not operate at night, which created instability and an extremely positive result,” Lt. Gen. Mangrich said. Air assets used heat sensors and satellites for monitoring and reconnaissance activities, and a command and control system to analyze and interpret the images. The information obtained contributed to the commander’s decision making for troops’ engagement. “During a night flight, a FAB aircraft identified the entry of illegal goods. The satellite provided a visual revealing the number of recipients waiting for the merchandise. Our special forces troops were ready for action at the location. We opted to avoid confrontation and prevent having many fatalities. We chose to throw a stun grenade to disperse the people and stop the illegal activity,” said Lt. Gen. Mangrich. Results For the officer, the operation helped confirm the implementation of a successful operational model that can be used when necessary. “We managed to close the border by sea, land, and air during the operation,” said Lt. Gen. Mangrich. Effective to protect borders, the operation also increased interoperability between forces and coordination with participating agencies. A command and control structure facilitated the coordination of well-organized efforts and efficient results. According to Adm. Ademir, Ágata Graal allowed service members to uncover river and land routes, and docks criminal organizations used in the area, as well as their modus operandi. “We nearly completely stopped drug and arms trafficking, and cross-border crimes,” Adm. Ademir said. “After we left the location, the Federal Highway Patrol broke arrest records,” said Lt. Gen. Mangrich. “We identified trucks gathered across the border and a possible route for illegal entry into the country with satellite help. As soon as the operation ended, they tried to enter and PRF was ready for action.”last_img read more
