    Science 8 July 2011: Vol. 333 no. 6039 pp. 173-175 Galaxy Zoo Volunteers Share Pain and Glory of Research 1.

Figure View larger version: * In this page * In a new window Space oddity. Greenish "voorwerp" spotted by a Dutch volunteer still intrigues scientists. "CREDIT: NASA, ESA, W. KEEL (UNIVERSITY OF ALABAMA), AND THE GALAXY ZOO TEAM" The automated surveys that are becoming increasingly common in astronomy are producing an embarrassment of riches for researchers. Projects such as the Sloan Digital Sky Survey (SDSS) are generating so much data that, in some cases, astronomers don't know what to do with them all. SDSS has compiled a list of more than 1 million galaxies. To glean information about galaxy evolution, however, astronomers need to know what type of galaxy each one is: spiral, barred spiral, elliptical, or something else. At present, the only reliable way to classify galaxies is to look at each one. But the SDSS list is so long that all the world's astronomers working together couldn't muster enough eyeballs for the task. Enter the "wisdom of crowds." An online effort called Galaxy Zoo, launched in 2007, set a standard for citizen-scientist participation projects. Zealous volunteers astonished the project's organizers by classifying the entire catalog years ahead of schedule. The results have brought real statistical rigor to a field used to samples too small to support firm conclusions. But that's not all. Buoyed by the curiosity and dedication of the volunteers, the Galaxy Zoo team went on to ask more-complicated classification questions that led to studies they hadn't thought possible. And in an online discussion forum on the Galaxy Zoo Web site, volunteers have pointed to anomalies that on closer inspection have turned out to be genuinely new astronomical objects.

"CREDIT: KOOS VAN DER LENDE/NEWSCOM" DENVER, COLORADO-The people who brought us the bad news about climate change are making an effort to help us figure out what to do about it. As climate scientists have shown, continuing to spew greenhouse gases into the atmosphere will surely bring sweeping changes to the world-changes that humans will find it difficult or impossible to adapt to. But beyond general warnings, there is another sort of vital climate research to be done, speakers told 1800 attendees at a meeting here last month. And so far, they warned, researchers have delivered precious little of the essential new science. At the meeting, subtitled "Climate Research in Service to Society,"* the new buzzword was "actionable": actionable science, actionable information, actionable knowledge. "There's an urgent need for actionable climate information based on sound science," said Ghassem Asrar, director of the World Climate Research Programme, the meeting's organizer based in Geneva, Switzerland. What's needed is not simply data but processed information that an engineer sizing a storm-water pipe to serve for the next 50 years or a farmer in Uganda considering irrigating his fields can use to make better decisions in a warming world.

USC researcher experiments with changing ocean chemistry | 89.3 KPCC - 0 views

    "USC researcher experiments with changing ocean chemistry Jan. 19, 2011 | Molly Peterson | KPCC In his lab, USC's Dave Hutchins is simulating possible future atmospheres and temperatures for the Earth. He says he's trying to figure out how tiny organisms that form the base of the food web will react to a more carbon-intense ocean. Burning fossil fuels doesn't just put more carbon into the atmosphere and help warm the climate. It's also changing the chemistry of sea water. KPCC's Molly Peterson visits a University of Southern California researcher who studies the consequences of a more corrosive ocean. Tailpipes and refineries and smokestacks as far as the eye can see in Los Angeles symbolize the way people change the planet's climate. They remind Dave Hutchins that the ocean's changing too. Hutchins teaches marine biology at USC. He says about a third of all the carbon, or CO2, that people have pushed into earth's atmosphere ends up in sea water - "which is a good thing for us because if the ocean hadn't taken up that CO2 the greenhouse effect would be far more advanced than it is." He smiles. Hutchins says that carbon is probably not so good for the ocean. "The more carbon dioxide that enters the ocean the more acidic the ocean gets." On the pH scale, smaller numbers represent more acidity. The Monterey Bay Aquarium Research Institute estimates we've pumped 500 million tons of carbon into the world's oceans. Dave Hutchins at USC says that carbon has already lowered the pH value for sea water. "By the end of this century we are going to have increased the amount of acid in the ocean by maybe 200 percent over natural pre-industrial levels," he says. "So we are driving the chemistry of the ocean into new territory - into areas that it has never seen." Hutchins is one of dozens of scientists who study the ripples of that new chemistry into the marine ecosystem. Now for an aside.

NSF Touts Family-Friendly Policies as Boon to Women - 0 views

    "Scientific Workforce NSF Touts Family-Friendly Policies as Boon to Women 1. Jeffrey Mervis Young women are forever asking Meg Urry, an astrophysicist at Yale University, if it's possible "to have a successful scientific career and a family." A tenured professor with both, Urry tells them "yes." Perhaps more telling, however, is that the issue doesn't seem to interest half of her students. "I've never been asked that question by a man," she says. This week, the National Science Foundation (NSF) rolled out a set of family-friendly policies that it hopes will reduce the number of young women who jettison scientific careers because of responsibilities outside the lab. "Too many women give up because of conflicts between their desire to start a family and their desire to ramp up their careers," says John Holdren, the president's science adviser and head of the Office of Science and Technology Policy. It was a rare moment in the spotlight for the low-profile basic research agency: First Lady Michelle Obama announced the policies at a White House ceremony touting the importance of women to the nation's economic recovery and, in particular, the need to improve the proportion of women in the so-called STEM (science, technology, engineering, and mathematics) workforce.

Add your own in the comments! 2012: The Year of the Squid From the giant squid's giant eyes (the better to see predatory sperm whales, my dear), to the vampire squid's eerie diet of remains and feces, the strange adaptations and behavior of these cephalopods amazed us all year. Scientists found a deep-sea squid that dismembers its own glowing arm to distract predators and make a daring escape. But fascinating findings weren't relegated to the deep: at the surface, some squids will rocket themselves above the waves to fly long distances at top speeds. James Cameron Explores the Deep Sea Filmmaker James Cameron has never shied away from marine movie plots (See: Titanic, The Abyss), but this year he showed he was truly fearless, becoming the first person to hit the deepest point on the seafloor (35,804 feet) in a solo submarine. While he only managed to bring up a single mud sample from the deepest region, he found thriving biodiversity in the other deep-sea areas his expedition explored, including giant versions of organisms found in shallow water.

    Webcast: 'We Sea Change,' a Climate Change Education Video 0 What is climate change, and how is it affecting coastal Carolina? That is the question that a group of teens from Isaac Bear Early College High School set out to answer for their Third National Student Summit on the Ocean & Coasts project. Representing the North Carolina Aquarium at Fort Fisher, four teens spent months researching climate change issues such as salt water intrusion in rivers, changes to barrier islands, disappearing beaches, and habitat loss in longleaf pine forests in the Wilmington, N.C., region. The students presented a video documenting this research during the National Student Summit on February 15, 2011 at the Smithsonian's National Museum of Natural History. After the Summit, the team broadened the project's scope to include climate change education through the production of a second video. This film, We Sea Change, aims to give their local community in Wilmington an understanding of climate change, impacts on the coastal Carolina region, and how people can be part of the climate change solution. We Sea Change will be broadcast live to the Ocean Portal from the North Carolina Aquarium at Fort Fisher on Wednesday, September 28, 2011 at 7pm. There will be a panel discussion on climate change immediately following the 7pm screening. Meet the team! The Cape Fear Beach Bears: Sandy Paws for a Cause team members include students Jessica Lama, Keela Sweeney, Evan Lucas, and Dustin Chambers. They have conducted research and produced their videos under the guidance of teachers Bryan Bishop from Isaac Bear Early College High School and Megan Ennes from the North Carolina Aquarium at Fort Fisher.

E-mail: porterm@maths.ox.ac.uk Visualization is a crucial but underappreciated part of science. As venues like the American Physical Society's Gallery of Fluid Motion and Gallery of Nonlinear Images illustrate every year, good visuals can make science more beautiful, more artistic, more tangible, and often more discernible. Katy Börner's continuing exhibition Places & Spaces: Mapping Science (1) and her book Atlas of Science: Visualizing What We Know arise from a similar spirit but are much more ambitious. Visualization is one of the most compelling aspects of science. Breathtaking visuals from sources like fractals and Disneyland's long-dead "Adventure Thru Inner Space" ride are what originally inspired me toward my personal scientific path, so I welcome any resource that promises to bring the visual joys of discovery to a wide audience. Importantly, Börner's exhibition and book are not mere artistic manifestations, although they would be impressive accomplishments even if that were her only goal. Some scientists have occasionally had great success in the visual arts; for example, physicist Eric Heller has long exhibited the gorgeous fruits of his research on quantum chaos and other topics (2). To fully appreciate Börner's efforts, however, one must be conscious that she is deeply concerned not just with visualization itself but with the science of visualization. Accordingly, her book discusses the history of the science of visualization, where it is now, and where she thinks it can go. Atlas of Scie

Flanked by desert, Ulan Bator will be cooled in summer by an "ice shield." "CREDIT: BRÜCKE-OSTEUROPA/WIKIPEDIA" As the coldest capital on Earth, you might think the last thing Ulan Bator needs is more ice. But that is just what it's about to get under a geoengineering trial aimed at "storing" freezing winter temperatures to cool and water the city during the summer. At the end of this month, engineers will drill a series of bores through the ice on the Tuul River, pump up water from below, and spray it on the surface where it will freeze. This process will be repeated throughout the winter, adding layer after layer to create a chunk of ice that will be 7 or 8 meters thick by the spring. It's an attempt to artificially create the ultra-thick slabs-known as naleds in Russian-that occur naturally in far northern climes when rivers or springs push through surface cracks. Nomads have long made their summer camps near such phenomena, which melt much later than normal ice. Flanked by desert and plagued by summer temperatures that can rise close to 40°C, Ulan Bator's municipal government hopes the $724,000 experiment will create a cool microclimate and provide fresh water as the naled melts. ECOS & EMI, the Anglo-Mongolian company behind the plan, has still greater ambitions. "Everyone is panicking about melting glaciers and icecaps, but nobody has yet found a cheap, environmentally friendly alternative," says Robin Grayson, a geologist in Ulan Bator for ECOS & EMI. "If you know how to manipulate them, naled ice shields can repair permafrost and build cool parks in cities." The process, Grayson says, can be replicated anywhere where winter temperatures fall below −5°C for at least a couple of months.

    "Some of the planet's most beautiful and diverse ecosystems are at risk. With temperatures on the rise, coral reefs are at greater risk for coral bleaching. Using ocean observing system data from NOAA's National Data Buoy Center, this classroom activity examines ocean temperatures off Puerto Rico to see how coral reefs are being impacted and predict what's on the horizon. Brought to you by Sea Grant's Bridge website and COSEE-NOW. This activity was developed in response to the 2005 massive coral bleaching event in the Caribbean caused by high sea surface temperatures. Using ocean observing system data, water temperatures can be monitored to evaluate the likeliness of other bleaching events. Via the COSEE-NOW online community, we were able to receive valuable feedback on making the graph of water temperature more user-friendly and expanding the discussion questions to evoke some higher level thinking from students. This activity has been demonstrated to teachers at the National Marine Educators Association conference and Virginia Sea Grant professional development institutes; and to graduate students in several different settings. http://www2.vims.edu/bridge/DATA.cfm?Bridge_Location=archive0406.html"

    The term ocean acidification is used to describe the ongoing decrease in ocean pH caused by human CO2 emissions, such as the burning of fossil fuels. It is the little known consequence of living in a high CO2 world, dubbed at the 2009 United Nations Climate Change Conference (COP15) as the "evil twin of climate change". The oceans currently absorb approximately half of the CO2 produced by burning fossil fuel; put simply, climate change would be far worse if it were not for the oceans. However, there is a cost to the oceans - when CO2 dissolves in seawater it forms carbonic acid and as more CO2 is taken up by the oceans surface, the pH decreases, moving towards a less alkaline and therefore more acidic state. Already ocean pH has decreased by about 30% and if we continue emitting CO2 at the same rate by 2100 ocean acidity will increase by about 150%, a rate that has not been experienced for at least 400,000 years. Such a monumental alteration in basic ocean chemistry is likely to have wide implications for ocean life, especially for those organisms that require calcium carbonate to build shells or skeletons. Ocean acidification is a relatively new field of research, with most of the studies having been conducted over the last decade. While it is gaining some attention among policy makers, international leaders and the media, scientists find there is still a lack of understanding.

Gulf Drilling Disaster Triggers Scrutiny of Mediterranean Oil Rush - 0 views

    "Oil Exploration Oil Exploration Gulf Drilling Disaster Triggers Scrutiny of Mediterranean Oil Rush 1. Laura Margottini* A rush to find and extract oil in the Mediterranean Sea is threatening one of the planet's marine biodiversity hot spots, scientists warn. PANTELLERIA, ITALY-This tiny speck in the Mediterranean, home to a few thousand people, seems like one of the most tranquil places in the world. But looks are deceptive. Pantelleria, in the Strait of Sicily halfway between Palermo and Tunis, is close to one of the world's busiest shipping lanes, and of late, its waters have also become the center of a new oil rush. Attracted by Italy's easygoing drilling regulations and low tax on oil extraction, dozens of companies have new plans for exploration and drilling in this part of the Mediterranean Sea. At a recent meeting here,* however, scientists, conservationists, and environmental activists warned that such efforts put several important biodiversity hot spots in danger. An oil disaster like the Deepwater Horizon explosion, which sent oil gushing into the Gulf of Mexico for months, could easily ruin the Mediterranean ecology for a century or longer, some said. The Italian government has recently issued 66 permissions for drilling around its coasts and 25 concessions for exploration. Another 67 applications for exploration are under review. "Italy now represents the region that holds the most exciting and significant long-term opportunities," one company, Northern Petroleum, says on its Web site. The Strait of Sicily is the center of attention, but other biodiversity hot spots, such as the Tremiti Islands in the Adriatic Sea, could soon be explored as well. Italy isn't alone. Tunisia, for example, has granted concessions for oil exploration for most of its Mediterranean waters, without much political opposition. But the areas coveted by oil companies are ecological treasures, researchers and groups such as Greenpeace Italy stress. Last year, the Uni

    Key Findings Current Coastal Management Challenges Current coastal management challenges are worsening. Top management challenges will be exacerbated by climate change. Current management challenges make adaptation planning and decision-making difficult. Climate Change Concerns, Knowledge, and Actions Attitudes and knowledge about climate change are strongly supportive of adaptation action. Attention to adaptation has increased markedly over the past five years. Adaptation planning and implementation is still in the very early stages. There is limited familiarity with innovative adaptation approaches. Information, Technical Assistance, and Training Needs Organizational missions, job responsibilities, and legal requirements shape common information use. Ease of access to information is the overriding determinant of information use. Specific information needs differ by professional group. Critical opportunities exist to meet coastal professionals' information, technical assistance, and training needs Survey Background Decision-makers in California's (CA) coastal counties recognize that climate change will impact their communities and coastline. Yet, coastal CA communities are at different stages in developing and/or implementing climate change adaptation plans. During the Summer of 2012, USC Sea Grant, in partnership with 14 other CA-based organizations (listed below), launched a survey to understand the needs and barriers coastal communities have in planning for climate change in order to develop appropriate trainings and technical assistance for communities and determine the best way to link communities to resources and tools already available.

    http://www.alaskafisheries.noaa.gov/newsreleases/2011/orangesubstance081811.pdf Alaska - NOAA determines "orange goo" in Alaska's Kivalina village is fungal spores The "orange goo" that washed ashore earlier this month in the remote Eskimo village of Kivalina along Alaska's northwest coast is fungal spores, not microscopic eggs as preliminary analysis indicated. Scientists at the NOAA Alaska Fisheries Science Center's Auke Bay Laboratory announced last week that the substance was biological in nature, rather than oil or pollution as originally thought by concerned residents of Kivalina. Per standard scientific procedure, samples were sent to NOAA's Analytical Response Team for a more thorough and detailed analysis and verification process. At NOAA's National Ocean Service Center for Coastal Environmental Health and Biomolecular Research, based in Charleston, S.C., a team of scientists highly-specialized and equipped to analyze microbiologic phenomena such as this determined that the substance is consistent with spores from a fungi that cause rust, a disease that infects only plants causing a rust-like appearance on leaves and stems. Rust fungi reproduce to infect other plants by releasing spores which disperse often times great distances by wind and water. However, whether this spore belongs to one of the 7,800 known species of rust fungi has not yet been determined. More information will be posted on the Alaska Fisheries Science Center website as it becomes available.

And those and likely other weather extremes will worsen in coming decades as greenhouse gases mount, the report finds. But uncertainties are rife in the still-emerging field of extreme events. Scientists cannot attribute a particular drought or flood to global warming, and they can say little about past or future trends in the risk of high-profile hazards such as tropical cyclones. Damage from weather disasters has been climbing, but the report can attribute that trend only to the increasing exposure of life and property to weather risks. Climate change may be involved, but a case cannot yet be made. Despite the uncertainties, the special report from the Intergovernmental Panel on Climate Change (IPCC) released 18 November stresses that there is still reason for taking action now. The panel recommends "low-regrets measures," such as improvements in everything from drainage systems to early warning systems. Such measures would benefit society in dealing with the current climate as well as with almost any range of possible future climates. The report takes a cautious, consensus-based approach that draws on the published literature. Headlines and even some scientists may point to the current Texas drought or the 2003 European heat wave as the result of the strengthening greenhouse. But the report fin

Researchers at NOAA developed Science On a Sphere® as an educational tool to help illustrate Earth System science to people of all ages. Animated images of complex processes such as ocean currents, sea level rise, and ocean acidification are used to to enhance the public's understanding of our dynamic environment. Ocean Acidification on Science On a Sphere® The movies below were developed for use on Science On a Sphere® and show computer model simulations of surface ocean pH and carbonate mineral saturation state for the years 1895 to 2094. The first movie shows a computer recreation of surface ocean pH from 1895 to the present, and it forecasts how ocean pH will drop even more between now and 2094. Dark gray dots show cold-water coral reefs. Medium gray dots show warm-water coral reefs. You can see that ocean acidification was slow at the beginning of the movie, but it speeds up as time goes on. This is because humans are releasing carbon dioxide faster than the atmosphere-ocean system can handle.
