Iceberg Headed for Sub-Antarctic Island Could Threaten Wildlife

first_img– Advertisement – It’s unpredictable what could happen if the iceberg were to run aground near South Georgia, said M Jackson, a glaciologist who is an explorer with the National Geographic Society. Such episodes are not unheard-of but greater attention is usually given to them when they pose a threat to people and wildlife, she said.- Advertisement – An iceberg roughly the size of Delaware that is headed toward the sub-Antarctic island of South Georgia has experts worried about the possibility of it blocking wildlife from food sources and threatening the island’s ecosystem.The iceberg, known as A68a, was about 400 kilometers, or about 250 miles, away from the coast of the British island territory of South Georgia as of Wednesday, the British Antarctic Survey said.- Advertisement – There is a chance that if A68a does run aground, it could disrupt part of South Georgia’s ecosystem, affecting some of the areas and paths that animals, such as seals and penguins, travel to hunt and gather food.“Essentially, seals and penguins birth on land, then commute back and forth into the ocean to source and return with food to feed their young,” Dr. Jackson said. “The iceberg might disrupt this, and seals and penguins might not be able to source and deliver food to their land-based pups and chicks, potentially triggering widespread starvation.”Douglas R. MacAyeal, a professor of geophysical sciences at the University of Chicago who has studied the behavior of large icebergs, compared A68a with another large iceberg, B-15A. In the 2000s, B-15A struck parts of Ross Island in the Ross Sea as well as the other icebergs surrounding it, disturbing the island’s penguin colonies. Some colonies went years without hatching chicks. The disturbance led to some penguins interbreeding with those from different colonies.“This led to a genetic benefit of exchange, of genetic material from different, normally isolated, cohorts,” Dr. MacAyeal said in an email. “In my view: If A68a were to encounter the island itself or the shoals around it, it would be spectacular for a few days but would not lead to an ecosystem catastrophe.”Some experts predict A68a will eventually break into large pieces as a result of strong currents.“The Southern Ocean around South Georgia is an utterly wild place with strong currents and sea-swell that will ‘flex’ the iceberg on top of the grounding point, causing it to stress and fracture much like a ship,” Dr. MacAyeal said.If the iceberg does break close to the island’s coast, there’s the potential that it could displace large amounts of seawater “that can inundate coastal communities,” Dr. Jackson said.This kind of hazard is something experts have had to grapple with as climate change has led to ice melting and ice systems breaking at significant rates.“I am doubtful given the increasing rate of ice melt worldwide that this is the last time we’ll see this,” Dr. Jackson said. “I wouldn’t be surprised in the years to come if we continue to see bigger icebergs presenting bigger hazards to communities of people and wildlife alike.”center_img The iceberg broke off from the Antarctic Peninsula in 2017 and is about 100 miles long and 30 miles wide. The trajectory of the iceberg could change and steer clear of the island, because it’s in the strongest ocean current where waters are not impeded by continents. This means the iceberg could easily sail past the island, all depending on the course nature takes. – Advertisement – The iceberg may run aground near the island and be a few weeks out from the island’s coast, said Andrew Fleming, a remote sensing manager with the survey.last_img read more

Sandro focuses on return

first_imgSandro says he is on course to return to action this summer when he hopes to go back to a Tottenham team who are competing in the Champions League. Press Association Last month Tottenham allowed Sandro to return to Brazil to recover from the serious knee injury which he sustained against QPR in January. In his absence, Tottenham have suffered. With six matches of the season remaining the north London club are in danger of just missing out on Champions League football for the second successive season. “We have to fight to stay in fourth place,” Sandro told Globo Esporte. center_img “Last year was complicated. We did not classify because Chelsea were the champions of Europe. The Champions League is a different competition (to the Europa League). Everything the fans see is what the player feels… the entrance music, the stadia, the fans… everything is amazing. “I first played in the competition in 2010 when we beat AC Milan at the San Siro. We beat Inter Milan, too, and we only lost in the quarter-finals to Real Madrid. It was a really great experience. Hopefully the club will compete in the competition again.” The good news for Tottenham boss Andre Villas-Boas is that, three months after twisting his knee, Sandro is on the mend. The midfielder’s rehab with his former club Internacional is going well, he insists, and he looks set to be fit for pre-season. “I’ve got three months to go,” Sandro said. “I’ve started to run, I’m developing. Sometimes I try too much and the knee swells up. I have to listen to the doctor. I have to give the injury enough time, but I dream that I am playing.” Sandro admits he was in the best form of his life before he suffered the injury. He now hopes to regain that sort of form so he can earn a place in Luiz Felipe Scolari’s squad for the 2014 World Cup in his homeland. “I was in the best phase of my life as a player, so it was hard when I had the injury,” said Sandro, who won a silver medal with his country at the Olympics. “I struggled with the language when I moved to Spurs (in March 2010), but (goalkeeper) Heurelho Gomes helped me. Today the coach is Portuguese, which helps me a lot. Hopefully I’ll be back playing with my club and then I can think about the national team. When I return I will be stronger.” last_img read more

Users of Apache Mesos and the Mesosphere Data Cent

first_imgUsers of Apache Mesos and the Mesosphere Data Center Operating System will be pleased to hear that they can begin integrating Google’s Project Kubernetes into their containerized cloud environments. Mesosphere today announced that it would begin including Kubernetes as a standard feature of its Mesosphere DCOS.Kubernetes, which was first announced publicly by Google last June, is an open-source project that can be used to manage an entire cluster of containerized applications as a single entity. Just two weeks ago, Kubernetes was integrated into CoreOS, and Red Hat has also been involved in the project.Craig McLuckie, product manager of cloud compute at Google, and one of the founders of the Kubernetes Project, said that the long-term goal is to bring Google’s internal cloud architecture and capabilities to the public as standard issue for all data centers. “The intent here is to make the tech as ubiquitous as possible,” he said. “The technology behind Kubernetes was inspired by the way we run all our workloads at Google. Kubernetes is about making containers operationally viable. We understand the value proposition of doing this. We launch 2 billion containers a week. Everything is running on containers. We’ve learned a few things around the complexity of managing container-packaged applications, and the value that provides.”To that end, one of the first things on the current Kubernetes road map is making the system production-ready. McLuckie said that this should happen in the next few months, and is currently the team’s top priority.Longer term, however, the goal is to make Kubernetes an even more effective resource-management platform than is currently available. McLuckie said the future of Kubernetes is “us moving up the stack and providing richer capabilities. This offers an amazing framework for resource isolation, so you can get more out of your infrastructure. You’ll see us providing ways to do much, much more efficient scheduling, and to get more efficiency out of data centers than most customers get.”last_img read more

As we continue to innovate in nearly every differe

first_imgAs we continue to innovate in nearly every different aspect of technology, there is one thing that has remained relatively consistent: PDF. That is not to say it hasn’t grown, just that it has been a format that companies have been able to rely on for the past 24 years. “Anytime there’s a need to deliver a document, or make it deliverable, or produce a version of it that is as it existed at a particular time and date, PDF is just the inevitable file format,” said Duff Johnson, executive director of the PDF Association, an organization that promotes the adoption and use of the International Standard for PDFs. “It has no competition in its niche and its niche is fairly significant.”Some of the challenges developers have faced when developing for PDF is that the specification gets very complicated. According to Johnson, the PDF specification is about a thousand pages long and is not similar to a lot of other specifications, especially to those coming from the world of HTML. “PDF has a core syntax that’s very well understood and that has a wide variety of very good implementations,” said Matt Kuznicki, CTO of Datalogics and chairman of the PDF Association. “But there’s a lot to PDF that a lot of people out there don’t know a lot about.” Even though it is fairly easy to get the basics of PDF down, when companies start to want to do more and utilize the full capabilities of PDF, it becomes harder for them. “Not all implementations are created equally so what we find is that the breadth, and the depth, and the quality of support for PDF features in different toolkits and different SDKs can vary quite a bit.” “A qualified PDF developer must be skilled in a broad spectrum of technologies, including cryptography, computer graphics and compiler construction, and must familiarize themselves with the range of application areas in which the format is used,” said Hans Bärfuss, CEO of PDF Tools. PDF Tools suggests developers focus on the application-oriented functions of PDF and leave the more basic functions to be handled by a software library. “The easier such a library is to use, the quicker the developer can implement the desired requirements and effective support from the manufacturer plays an important role in this,” Bärfuss said. Earlier this year, the PDF 2.0 standard was released, featuring many improvements to the format. The new standard was created with the goal of refining the language of the PDF specification and to smooth over areas that were confusing for those that implement PDF, according to Kuznicki. According to Johnson, PDF 2.0 dramatically improves interoperability for PDF. “Developers can now read the specification, choose to support this or that PDF feature and implement it with very high confidence that other developers also supporting that feature will be reading off the same page, and thus improving interoperability,” he said. “It’s a far better specification, more complete, more detailed, and fully documented.”“PDF is part of a universe of document formats such as HTML5, SVG, etc., and rather than standing alone, is part of broader multichannel communications,” said Bärfuss. “PDF should therefore be increasingly focused on interoperability with these formats, and include characteristics such as responsiveness. However, it should also not lose its role as an ‘electronic paper’ format.”Even though PDF 2.0 has been released, work continues to be done to improve it. According to Johnson, the ISO committee that owns PDF met in San Jose at the end of October to discuss their plans for the future, including whether or not to release PDF 2.1 soon or wait until there is a substantial update.  He expects that the 2.0 standard will be the version of PDF that developers continue to implement for next five to 10 years, at least. “I expect work that happens with PDF past 2.0 will really build on an evolutionary manner on PDFs capabilities while continuing to keep as foundational the notion of being a reliable and a portable document format and a means for people to convey information to others,” said Kuznicki. “The future for PDF looks very bright, there’s really nothing else on the horizon that can do what PDF does and it’s very clear that PDF meets critical business needs in a vast variety of workflows,” said Johnson. Utilizing the new features of PDF 2.0SD Times talked to companies about how they are utilizing the new features of PDF 2.0 to make their product better.DatalogicsAs a provider of PDF developer and SDK tools, our products enable our customers to expand and enable the increased functionalities of PDF 2.0. We, too, are keen to see the continued progress of PDF 2.0 ourselves and how our customers will develop new and innovative workflows, tools, and solutions for their end users.We have and will continue to support the PDF 2.0 standard moving forward. In fact, Datalogics donated an initial set of example PDF 2.0 files to the PDF Association to help in their mission of providing technical resources and education to PDF practitioners. Datalogics will maintain active participation in defining the 2.0 standard and supporting its future.PDF ToolsPDF 2.0 offers a wide variety of new features for various application areas. Some of them have already been implemented in our products and others will be implemented in the near future. Here some examples:Digital Signatures are an important means to guarantee the integrity and authenticity of  transaction documents. PDF 2.0 has been extended to support ECC-based certificates, CAdES signatures, long term validation, document security store and timestamps dictionaries. These features help to realize separate signature creation and verification processes over a long time period.Prepress documents now can profit from new features such as use of black point compensation, page-level output intents, external output intents, halftone origins, and extensions to output intents such as mixing hints and spectral data. These features make it easier to process hybrid documents from various sources and for various output devices.Documents for mass-printing now can be structured using document parts. This feature helps to implement document driven print and packaging processes.Documents for interactive use may now contain more features such as rich media annotations, measurement and point data, 3D measurements, various go to actions and many more.Many features have not been mentioned here. Nevertheless, the will be added to our products if the there’s a demand for them in the years to come.last_img read more
