Photo Credit: © Brian Skerry, www.brianskerry.com Despite covering 70 percent of the earth's surface, the ocean doesn't often make it into the news. But when it does, it makes quite a splash (so to speak). Here are the top ten ocean stories we couldn't stop talking about this year, in no particular order. 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. Schooling sardines form a "bait ball." Small fish, such as these schooling sardines, received well-deserved attention for being an important part of the food chain in 2012.

    "Science 25 November 2011: Vol. 334 no. 6059 p. 1040 DOI: 10.1126/science.334.6059.1040 * News & Analysis Climate Change Humans Are Driving Extreme Weather; Time to Prepare 1. Richard A. Kerr Figure View larger version: * In this page * In a new window Thai floods 2011 Hurricane Katrina 2005 Texas drought 2011 "CREDITS (LEFT TO RIGHT): PAULA BRONSTEIN/GETTY IMAGES; JEFF SCHMALTZ, MODIS RAPID RESPONSE TEAM, NASA/GSFC; NOAA" An international scientific assessment finds for the first time that human activity has indeed driven not just global warming but also increases in some extreme weather and climate events around the world in recent decades. 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

  •  
    RISE ABOVE PLASTIC (RAP) SUCCESS! Green Ambassadors, in partnership with The Surfrider Foundation and The Algalita Marine Research Foundation, created the Rise Above Plastics Program, a student speaker series that encourages Los Angelenos to curb their single-use habits. Through the program, students learn about the impact of plastics on our lives and the environment, including plastic marine debris, chemicals and toxins. Students spread the word to their peers and the community by delivering engaging presentations that encourage practical solutions. In addition to learning about the inherent problems of living in a throwaway society, students learn the value of teamwork and polish their public speaking and presentation skills. In 2009, nearly 20 students participated in the program, delivering 30 presentations to more than 850 students and community members!

But usable knowledge is in short supply. Figure View larger version: * In this page * In a new window Adapt to that. Climate will change, but decision-makers want to know how, where, and when. "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. Researchers preparing for the next international climate assessment, due in 2013, delive

    perspective "The distribution of species on Earth and the interactions among them are tightly linked to historical and contemporary climate, so that global climate change will transform the world in which we live. Biological models can now credibly link recent decadal trends in field data to climate change, but predicting future impacts on biological communities is a major challenge. Attempts to move beyond general macroecological predictions of climate change impact on one hand, and observations from specific, local-scale cases, small-scale experiments, or studies of a few species on the other, raise a plethora of unanswered questions. On page 1124 of this issue, Harley (1) reports results that cast new light on how biodiversity, across different trophic levels, responds to climate change. "

    "Stephanie Keske does computer visualization work, and is starting a graduate program this fall at Texas A&M University. She told me, "Just living on a ship, I think … you know, I try to be outside as much as I can so just being trapped on a floating hunk of metal is maybe going to be a little difficult. I don't know: I've never been in one place with an inability to leave it for 2 months solid." At the moment, Keske's in the northeast Pacific onboard an oceanographic research vessel. She and six other educators and artists from the US and France are working with the science team to do unprecedented outreach. Have a listen."

    "Welcome to the Penguin Science Education Page! Here you will find fun and educational activities to help students learn about many interesting aspects of Adelie penguin life, history and their relationship to climate change. Students can also send questions to the researchers who study penguins, check the nests of penguins as they look today, and (if the season is right) even receive a postcard from Antarctica! Adelie Penguin's existence in the far south region of our planet is a fascinating subject. The average day in the life of a penguin is filled with adventure and drama, as they struggle to live and thrive in a challenging environment and changing climate. "

    Summary: Assess coral bleaching using water temperature data from the NOAA National Data Buoy Center. Objectives * Describe the relationship between corals and zooxanthellae. * Identify stresses to corals. * Explain coral bleaching and the processes that cause coral bleaching. * Examine water temperature data and compare to levels known to induce coral bleaching. * Predict the effects of prolonged, increased temperaturs on coral reefs. Introduction The magnificent beauty of a coral reef is a true masterpiece of Mother Nature. A reef is a sculpture of living organisms, varied in color, texture, shape, and size. The creation of these works of art takes many, many years (some reefs are thousands of years old), and they don't exist solely for show. Reefs are building blocks for rich communities, providing habitat for a myriad of organisms, and they are some of the most diverse ecosystems on the planet. In addition, they support fishing grounds, attract tourists, and protect shorelines from waves and storms. "

Joint Expedition Discovers Deep-Sea Biodiversity, New Volcanoes - 0 views

  •  
    The shallow water reefs of the Coral Triangle, which stretches across Indonesia and north through the Philippines, host the world's greatest diversity of corals, fish, crustaceans, mollusks, and marine plant species. Now preliminary results from a joint Indonesian-U.S. marine survey indicate that the biodiversity runs deep. A remotely operated vehicle has captured stunning images of massive corals, as well as unusual crustaceans and fish living at depths never before surveyed, thousands of meters below the surface. And mapping of that sea floor has turned up a huge, previously unknown volcano.

    "What are the impacts of ocean acidification on key benthic (seabed) ecosystems, communities, habitats, species and their life cycles? The average acidity (pH) of the world's oceans has been stable for the last 25 million years. However, the oceans are now absorbing so much man made CO2 from the atmosphere that measurable changes in seawater pH and carbonate chemistry can be seen. It is predicted that this could affect the basic biological functions of many marine organisms. This in turn could have implications for the survival of populations and communities, as well as the maintenance of biodiversity and ecosystem function. In the seas around the UK, the habitats that make up the seafloor, along with the animals associated with them, play a crucial role in maintaining a healthy and productive marine ecosystem. This is important considering 40% of the world's population lives within 100km of the coast and many of these people depend on coastal systems for food, economic prosperity and well-being. Given that coastal habitats also harbour incredibly high levels of biodiversity, any environmental change that affects these important ecosystems could have substantial environmental and economical impacts. During several recent international meetings scientific experts have concluded that new research is urgently needed. In particular we need long-term studies that determine: which organisms are likely to be tolerant to high CO2 and which are vulnerable; whether organisms will have time to adapt or acclimatise to this rapid environmental change; and how the interactions between individuals that determine ecosystem structure will be affected. This current lack of understanding is a major problem as ocean acidification is a rapidly evolving management issue and, with an insufficient knowledge base, policy makers and managers are struggling to formulate effective strategies to sustain and protect the marine environment in the face of ocean acidification."

    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.

    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.
