The University of Minnesota's Institute on the Environment has made some great movies examining what they call "big questions."
Big question: Feast or famine?
IonE's first Big Question asks: How do we feed a growing world without destroying the planet?
Big question: Is Earth past the tipping point?
Have we pushed our planet past the tipping point? That's a critical issue the IonE explores in our second Big Question video.
Big question: What is nature worth?
Plants, animals, even entire ecosystems are disappearing. So what? "What is Nature Worth" offers a three-minute look at what we’re REALLY losing – and what we can do about it.
Interesting problems, right? If you're intrigued, and want to know more about the folks posing the questions and trying to find the solutions, jump over to Future Earth.
Courtesy C-MOREYou’ve probably seen all sorts of colors in the ocean: deep-blue, turquoise-blue, light-green, brown, even gray on a gray day. But red? Microbial oceanographers on C-MORE's (Center for Microbial Oceanography: Research and Education) BiG RAPA oceanographic expedition have seen a red ocean off the coast of Chile! Huh?! Learn what a plankton net is, and then see what caused the strange red color.
Courtesy C-MOREDr. Dan Repeta from the Woods Hole Oceanographic Institution (WHOI) is C-MORE’s Chief Scientist on the BiG RAPA expedition, which is conducting research off the coast of Chile. Dr. Repeta and his team of scientists are sampling the underwater microbial environment using a variety of instruments, including a water collector called a CTD (see educational resource below). Two interesting results have turned up in the CTD data:

Courtesy C-MOREWell, yeah, that’s right. Microbes don’t smile, and they sure don’t command an oceanographic ship. However, there are lots of microbes in the sea; in fact, they account for most of the total marine biomass. With that in mind, there’s no question about microbes being fundamental to the functioning and health of the oceans.
Courtesy Scripps Institution of OceanographyScientists from C-MORE (Center for Microbial Oceanography: Research and Education) and the Universidad de Concepción, Chile have organized an expedition to one of the most sparsely sampled oceanic regions on the planet…the southeast Pacific Ocean. The expedition’s official name is BiG RAPA (Biogeochemical Gradients: Role in Arranging Planktonic Assemblages). It departed from Chile on November 17 on the research ship Melville and will travel almost due west, ending at Rapa Nui (Easter Island) on December 14.
Courtesy C-MOREOceanographers will conduct studies on a microbial community that exists in a very curious environment. The Melville will travel from the nutrient-rich coastal waters off Chile into the low-nutrient area known as the South Pacific Subtropical Gyre. The SPSG is the most oligotrophic, or nutrient-poor, of all sub-tropical gyres. What kind of microbes can live in such an impoverished area? How do they do it?

Courtesy B. MayerWho hasn’t heard about the very great scientific and social problems of global warming and ocean acidification? As microbiologist Louis Pasteur noted more than a century ago, “The very great is accomplished by the very small.” Part of the answer to these very great problems can be accomplished by understanding the very small: ocean microbes, living things that are less than a hundredth of the thickness of a human hair.
Our effort to understand the very small in the ocean has just taken a big step. C-MORE Hale (Hawaiian language for “house,” pronounced hah-lay) was officially dedicated in a ceremony that took place on October 25, 2010. C-MORE, or the Center for Microbial Oceanography: Research & Education, is all about studying ocean microbes. Scientists at C-MORE are looking into microorganisms at the genomic, DNA level and all the way up to the biome level where microbes recycle elements in ocean ecosystems.
Headquartered at the University of Hawai`i, C-MORE’s interdisciplinary team includes scientists, engineers and educators from the Massachusetts Institute of Technology, Monterey Bay Aquarium Research Institute, Oregon State University, University of California – Santa Cruz and Woods Hole Oceanographic Institution. As a National Science Foundation center, C-MORE is a dynamic “think tank” community of researchers, educators and students from a variety of cultural backgrounds, including native Hawaiian and other Pacific Islander.
Courtesy B. MayerC-MORE Hale will be equipped completely and ready for scientists to put on their lab coats and get to work in January 2011. For now, e komo mai! (welcome!) Imagine yourself walking along this sidewalk leading to C-MORE Hale. Stop for a moment to look at the round pavers; they depict ocean microbes first discovered by 19th century zoologists on the worldwide HMS Challenger expedition. Step past these unique designs and take a tour of the brand-new building!
During the 1960s an average of 5 dams per day were built in the U.S. Many of those were licensed for thirty or fifty years of operation. So, as we approach the close of 2010, a lot of our dams are itchin’ to come down.
As you may imagine, removing a 95-year-old, 210-foot tall dam is no easy feat.
Enter Dr. Gordon Grant, research hydrologist with the USDA Forest Service and professor at Oregon State University. Gordon has worked on some of the largest dam removals in the history of the U.S. Tonight he is all set to tell us about such endeavors. Gordon will be speaking at Research at the Red Stag at 5:30pm. His talk is entitled “Out, out damn’d dam: freeing wild rivers.” It will certainly be a highlight of my November.

Have you ever heard of ‘ocean acidification’? If not, don’t feel alone. You are in vast majority. A new study by Dr. Anthony Leiserowitz at Yale University found that that just 25 percent of Americans have ever heard of ocean acidification – the process whereby carbon dioxide released into the atmosphere by human activities eventually dissolves into the sea producing carbonic acid which depresses the pH of the ocean. Ocean acidification threatens to dramatically alter marine life if present trends continue. A more informed citizenry is essential if steps are to be taken to address this threat to our futures.
The Science Museum of Minnesota and Fresh Energy on the evening of Thursday, November 4 are hosting the Twin Cities film premiere of the documentary, A Sea Change . The screening of this award-winning, 90-minute film will begin at 6:30 PM followed by Q&A with the film’s director, co-producer, lead NOAA ocean acidification scientist, and Fresh Energy’s science policy director and then concluding with a dessert reception. I hope that you will take advantage of this unique opportunity to see the film and then socialize afterwards. Go to the Science Museum's adult programs to order your tickets.

She was part of the STARS program (Science Teachers Aboard Research Ships) operated by C-MORE (Center for Microbial Oceanography: Research and Education) at the University of Hawai`i's School of Ocean, Earth Science & Technology.
Courtesy C-MORE Ever since 1988 scientists from UH’s HOT program (Hawai`i Ocean Time-series) have been gathering monthly baseline data from station ALOHA, a deep-water site about 60 miles north of Honolulu. This data lead to the discoveries about rising sea surface temperatures and ocean acidification. Dana and two other teachers were part of this continued ocean chemistry and physics data collection, as they worked alongside shipboard scientists at station ALOHA.

Courtesy C-MORE Dana also came face-to-face with Pacific Ocean micro-critters that were captured in a plankton net. What a variety there were! Some were phytoplankton, the microscopic floating plants of the open ocean, and others were tiny animals belonging to the zooplankton. As a whole, plankton are extremely important to the oceanic ecosystems because they form the base of most food webs. Dana used dichotomous keys from C-MORE's Plankton science kit to identify the open-ocean specimens.
