Rb-Sr geochronology of Graham Land, Antarctica

first_imgThirty-five new Rb-Sr whole-rock and mineral isochrons are reported for igneous rocks from Graham Land. Magmatism was essentially continuous but peaks of activity occurred in early Jurassic, early Cretaceous, late Cretaceous and Eocene times. The oldest dated granite is Triassic (209 ± 3 Ma). Volcanic rocks were erupted throughout this history and some previously supposed Upper Jurassic volcanic rocks must be mid-Cretaceous or younger. A change in magma type, from uniformly acid to predominantly basic or intermediate, combined with westward migration of the arc, may be partly responsible for previously reported transverse geochemical variations. There is a marked trend of decreasing initial 87Sr/86Sr ratio of the plutonic rocks with time, from c. 0.707 to 0.704, although volcanic rocks tend to have higher values. This trend is ascribed to the waning influence of an, as yet unidentified, pre-magmatic crustal basement, due to increasing depth of magma generation. Close parallels to the observed age pattern imply continuity of the Andean belt through southern South America into Graham Land back to early Mesozoic times and are not compatible with reconstructions of Gondwana in which the Antarctic Peninsula is located W of South America.last_img read more

Diving behaviour of the grey-headed albatross

first_imgForaging grey-headed albatrosses spent 86% of the night but only 20% of the day sitting on the sea; most diving activity occurred during daylight. During the broad-guard period of nesting, peaks of diving activity occurred at midday and dusk. During the subsequent chick-rearing period, however, diving was mainly at dawn and dusk. Of 485 dives measured, the depth averaged 0.74 m, with maximum depth at 6.5 m. On average grey-headed albatrosses dived 24 times during a five day foraging trip. Dive depths increased towards midday, probably as a function of the birds’ visual acuity rather than due to vertical migration of their prey. We estimate that grey-headed albatrosses may obtain 30–45% of their daily food requirements by diving.last_img read more

Statewide Variety Testing

first_imgWhen Gassett and his team receive the information for each crop at each different location, the information is combined and two- or three-year averages taken. Results can vary due to different weather conditions, like rainfall on the crops or high and low temperatures. For example, excessive rainfall defined the growing season in 2013, whereas, during this year, July and August incurred a drought. Gassett publishes the information for farmers as soon as the crops are harvested.According to Gassett, every detail of each crop’s performance is crucial to farmers. The program documents yields, bloom dates, maturity dates, weights, heights, lodgings, seed sizes and seed shatterings. “Many things affect agriculture. The more farmers know, the better decision they can make for their farm, future and family,” Gassett said.Farmers across the state and throughout the Southeast use the information Gassett’s team provides. “We are a major part of the tools that the university has to offer the agriculture industry. I feel that our Extension agents utilize our data to assist farmers in their decisions. The UGA crop production guides, Extension agents and our crop specialists should also be a part of a farmer’s toolbox,” Gassett said. “The more information available, the more educated decisions can be made.”For more information about the program, see the Statewide Variety Testing program’s website at www.swvt.uga.edu.(Jordan Hill is an intern with the UGA Tifton Campus.) Georgia farmers need to know what crops can be grown efficiently and successfully in their region of the state. Guidance from University of Georgia College of Agricultural and Environmental Sciences personnel with the college’s Statewide Variety Testing program help farmers decide what to plant in the spring.John Gassett, coordinator of the Statewide Variety Testing program, works with other UGA personnel to research which crops are most successful in different regions of the state. Gassett’s team tests corn, soybeans, peanuts, cotton and small grains, including barley, oat, rye, triticale hay and wheat to help in this determination.“The farmer’s number one decision is variety selection,” Gassett said. “If farmers don’t choose an adapted variety, they will not be successful.”Adapted varieties refer to crops that are suitable for planting in a specific climate and soil type. A variety that may be conducive in Midville, or southeast Georgia, may not produce the same results when planted in Plains, or southwest Georgia. Gassett and his team work year-round to provide accurate, timely, unbiased data to help farmers make the best variety selection possible. During the year, the team plants, manages and harvests these crops at seven locations across Georgia, including Blairsville, Rome, Griffin, Athens, Midville, Tifton and Plains.Anthony Black, superintendent of the college’s Southeast Georgia Research and Education Center in Midville, cites the importance of testing the same crops in different locations: “Different varieties behave differently in different environmental situations,” he said.last_img read more

Brazil and U.S. Sign Agreement for Rocket Launch Center Use

first_imgBy Andréa Barretto/Diálogo April 04, 2019 Brazilian President Jair Bolsonaro conducted his first official visit to the United States, following an invitation from U.S. President Donald Trump, March 17-19, 2019. In one of the highlights of the meeting, both countries signed the Technology Safeguards Agreement (TSA), after nearly 20 years of dialogue. The treaty will allow U.S. companies—and companies from other countries who leverage U.S. technology in their satellites and rockets—to launch from the Alcântara Launch Center (CLA, in Portuguese), with the guarantee that technology and patents will be protected against unauthorized use or copy. “Brazil’s proximity to the equator makes it an ideal launch location. My administration is committed to reviving America’s proud legacy in space. We’re looking very strongly, as you know, and working together with everybody on Space Force. And we are grateful for Brazil’s partnership,” said President Trump during a ceremony at the White House Rose Garden, March 19. CLA—in the state of Maranhão, in the northeast of Brazil—is about 225 kilometers from the equator. Launches from this base shorten space travel, with fuel savings that analysts estimate at 20 to 30 percent. The location also has easy access to the sea, which is important for containers arriving on ships. History of dialogue The terms of the recently signed agreement have been underway since 2000. At the time, differences regarding privacy information and access to certain areas of CLA curbed the progress of negotiations. One of the most controversial topics in the previous agreement was the projection of segregated areas to which Brazilians could not enter. The new terms only call for access restrictions. Some places will only allow the entry of U.S. technicians carrying a badge issued by both Brazil and the United States. Police, firefighters, and Brazilian investigators will enter as needed. U.S. rockets will be assembled in those areas. The United States uses other bases around the world with the same setup and under similar agreements. Another circumvented aspect, according to the current terms, is the inspection of U.S. shipped containers that will now be allowed to go through Brazilian Customs. The Brazilian government must be informed of the rocket’s orbit, as well as the presence of radioactive artifacts housed at CLA. In addition, the use of CLA will be civil and peaceful—an important point as a lot of the equipment and software, which place satellites into orbit, are also used to launch missiles. Those are prohibited from being launched from Alcântara. Leap forward in development “This will be very good for the state and for the [Maranhão] region,” said Brazilian Minister of Science, Technology, Innovation, and Communications Marcos Pontes, a former astronaut. He and Brazilian Minister of Foreign Affairs Ernesto Araújo signed the TSA during a ceremony at the U.S. Chamber of Commerce, in Washington D.C., on March 18, alongside U.S. Assistant Secretary for International Security and Nonproliferation Christopher Ford. The agreement still requires approval from the Brazilian Congress. The U.S. Kennedy Space Center inspired the Brazilian government to transform CLA’s surrounding region. According to Pontes, the commercial use of the U.S. launch base advanced the local economy, following challenges faced toward the end of NASA’s space shuttle program. Likewise, Brazil intends to create a plan to promote professional training and generate jobs in Alcântara, and “help companies and local startups, who can also work with the center, grow, all of which increases local wealth, quality of life, and so forth. This is the only way to make it work well,” Pontes said. In addition to local impact, the agreement enables Brazil to renew dreams of developing its space program. In late 2018, the Brazilian Air Force estimated that tax collections could amount to $35 million per year just on CLA launches. The amount corresponds to five times the annual average the country invested in its national space program in the last 10 years. This new potential capital could allow for planned resource injections in the national space sector.last_img read more

The top social media trends of 2017

first_img 18SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr Have you ever seen a celebrity mention a product in their social media? It probably made you want that product or at least curious about what it is. This is called influencer marketing. It was the number one trend for brands in 2017, and you can plan on it remaining a dominant trend for 2018. Influencer marketing is when a brand gets their product to be mentioned, talked about or shared by a celebrity, influential blogger or industry leader. Consumers want to hear that a product is worth buying from someone they know to be knowledgeable. This type of social media marketing makes you feel as though the product is not only reliable but desirable.  I’ll admit Chrissy Teigen always gets me with any product related to food.Move over millennials. To my fellow millennials, the day has come for us to be referred to as “old.” We are now too old to be considered the primary demographic; brands began targeting a new generation in 2017, say hello to Generation Z.Generation Z refers to people born during or after 1995. They are close to $44 billion in purchasing power and will start defining how we use social media. What’s the difference between millennials and Generation Z? Generation Z values privacy more than millennials, and they are easily bored. The main difference is that they are harder to target because of their resistance to advertising. continue reading »last_img read more

Town of Dickinson receives $1 million grant toward water infrastructure

first_imgTOWN OF DICKINSON (WBNG) — State Senator Fred Akshar and Town of Dickinson Supervisor Mike Marinaccio announced funding to improve water infrastructure in the town of Dickinson Friday morning. The senator’s office says the funds ensure taxes and water rates will not be raised on the people of the town of Dickinson to help complete the project. PHOTO CREDIT: Office of State Senator Fred Akshar In the same press release, Marinaccio called the piping replacement project “major” and said the grant was necessary for the project’s completion. In August, the town had 15 water breaks over the course of three weeks due to failing infrastructure, Akshar’s office says. Senator Akshar’s office says $1 million was secured through the New York State Department of Health to help replace over 6,000 feet of piping. In a press release sent to 12 News, Akshar says clean water is essential to the growth of communities.last_img read more
