UMaine Mentioned in Press Herald, BDN Articles on Tick Increase

Wednesday, August 20th, 2014

The University of Maine was mentioned in articles by the Portland Press Herald and Bangor Daily News on climate change and the increase of ticks and Lyme disease. Both reports referenced a question on the November ballot that will ask voters to approve an $8 million bond that would support a laboratory administered by the University of Maine Cooperative Extension for monitoring Lyme disease and other health threats related to mosquitoes, bed bugs and ticks. Research from UMaine’s Climate Change Institute also was referenced in the BDN article. A clinical research associate at the Maine Medical Center Research Institute, which tracks tick populations in the state, said CCI research shows the state will grow significantly warmer by 2050.

Pulse Morning Show Interviews Davids about HIAD

Tuesday, August 19th, 2014

Bill Davids, chair of the University of Maine Civil and Environmental Engineering Department and the John C. Bridge Professor, was a Tuesday morning guest of host Don Cookson on The Pulse Morning Show on AM 620. Davids talked about how UMaine engineers and students are helping NASA test Hypersonic Inflatable Aerodynamic Decelerator (HIAD) technology. HIAD — a spacecraft nose-mounted “giant cone of inner tubes” stacked like a ring toy — slows a spacecraft as it enters a planet’s atmosphere. The technology may make it possible for a spaceship large enough to carry astronauts and heavy loads of scientific equipment to explore Mars — 34,092,627 miles from Earth — and beyond. Davids said the minimum three-year project is a wonderful opportunity for the university, as well as the two full-time doctoral candidates and six undergraduate students taking part in the testing.

Nelson Quoted in BDN Article on Acid Rain Effects

Monday, August 18th, 2014

Sarah Nelson, an assistant research professor with the Senator George J. Mitchell Center and cooperating assistant research professor in Watershed Biogeochemistry in the UMaine School of Forest Resources, was interviewed for a Bangor Daily News article about her research with Steve Kahl, a sustainability professor at Unity College, on acid rain. After a decades-long study, the researchers found the negative effects of acid rain have been reversed much faster than expected. Nelson said the study shows the value of long-term monitoring. “Because these lakes have been sampled for so long, they’re really sentinels of what’s been going on in the Northeast,” she said. “It’s really an amazing resource.”

CCAR Outreach Efforts Featured in Aquaculture North America Article

Thursday, August 14th, 2014

The University of Maine’s Center for Cooperative Aquaculture (CCAR) in Franklin was mentioned in an Aquaculture North America article about Acadia Harvest Inc. of Brunswick, Maine, reaching the final pilot phase of its work on land-based re-circ aquaculture of California yellowtail. The company also is laying the groundwork for commercial production of yellowtail, and hopes to add black sea bass in the future, the article states. Taylor Pryor, a chief scientist and marine biologist at Acadia Harvest Inc., said the company wouldn’t have accomplished as much in the past three years without the expertise at CCAR, which supports aquaculture business incubation. “The CCAR staff are wonderfully competent in their hatchery work,” Pryor said. “Having their expertise and the CCAR facility can vastly reduce the time needed to move projects forward.”

Media Report on $20M Grant to Launch Sustainable Ecological Aquaculture Network in Maine

Thursday, August 7th, 2014

The Portland Press Herald, WABI (Channel 5), Maine Public Broadcasting Network, Bangor Daily News and Mainebiz reported a $20 million National Science Foundation EPSCoR grant will establish a Sustainable Ecological Aquaculture Network (SEANET) program in Maine. Maine EPSCoR at the University of Maine will use the grant to mobilize the collective capacity of Maine’s coastal science resources to establish SEANET, a research network focused on sustainable ecological aquaculture. The public-private partnership led by UMaine, in collaboration with the University of New England and other institutions, will use the state’s 3,500-mile coastline as a living laboratory to study physical oceanography, biophysical, biogeochemical, socioeconomic and policy interactions that have local, bioregional, national and global implications. Paul Anderson, director of SEANET at UMaine, told MPBN the grant offers a good opportunity to look at how aquaculture can be part of the seafood sector by working with the commercial fishing and tourism industries.

UMaine Researchers Studying Availability of Iron in Ocean, Primary Production

Wednesday, August 6th, 2014

Understanding why phytoplankton — the base of the food web — are not able to use all the iron in seawater is the focus of a three-year study by University of Maine researchers.

Mark Wells, a marine science professor at UMaine, is leading the project that will look at how the chemistry of iron in seawater is controlled by tiny particles, where the particles are most important, and how the chemistry of the particles affects the ability of phytoplankton to grow on iron in seawater.

Oceans contribute about 50 percent of the world’s photosynthesis, with the majority coming from marine phytoplankton, Wells says. The growth of the single-celled organisms in many ocean regions is limited by the availability of micronutrient iron.

The researchers will meld chemistry, physics and biology to learn more about dissolved iron in the ocean that is tied up in colloidal particles, which are too small for gravity to control, and therefore don’t sink in seawater.

“The question is whether the marine colloids are releasing iron, or gathering it up, and this pattern almost certainly will change for different waters,” Wells says. “It is like a Tic Tac container. The Tic Tacs are there but you have to wait for the container to release them before you can eat them.”

Bioavailable iron is an essential nutrient for shaping the distribution and composition of marine phytoplankton production, as well as the magnitude of ocean carbon export, the researchers say. Iron exists in many phases in the ocean and colloidal, or nonsoluble, phases account for a significant portion of dissolved iron.

The colloidal phase of iron may serve as a biological source of stored iron, according to the researchers, but the physical and chemical characteristics of these phases are presently poorly understood.

“We know the particles are there, but we haven’t had the techniques to really see them in a technical way, and that’s what makes this project unique,” Wells says.

To better understand this key part of iron cycling, researchers will use new analytical chemistry methods to quantitatively separate the colloidal iron sizes present in a sample and measure the composition of the colloidal portions in shelf and oceanic waters.They will use flow field-flow fractionation (flow FFF) with multi-angle laser light scattering to make measurements of the uniformity or uniqueness of the colloidal size spectrum, as well as the physical and chemical characteristics of the phases. Flow FFF, according to Wells, uses flow in thin streams along a membrane to separate small particles by size.

“Researchers in the past have just used filters, but filters aren’t a very efficient way to separate size,” Wells says.

Using this method will allow the researchers to learn more about the shape, size range and chemical composition of the particles.

“A mixture of particle sizes go in one end of the channel but particles come out the other in order of their size. We can use the method to determine what particle sizes have the most iron in them,” Wells says.

The findings will aid future studies to better link the source and fate of iron in the marine environment, according to the researchers, who also expect the project will have broad implications in the fields of marine ecology and biogeochemistry and to modeling studies of ocean-atmospheric coupling and climate change.

“This study will help us understand where iron will be more available and less available in the oceans, which will help us understand why ocean productivity is lower in some areas than others,” Wells says.

The project, “Assessment of the colloidal iron size spectrum in coastal and oceanic waters” recently received a $269,334 grant from the National Science Foundation.

A former UMaine postdoctoral researcher, who is now a Texas A&M University professor, will serve as a principal investigator on the project that also will support the education and research training of one undergraduate student each year. The researchers plan to conduct outreach activities to K–12 students and teachers.

Media Report on $18M Grant Awarded to Network for Biomedical Research, Workforce Training

Tuesday, August 5th, 2014

The Associated Press, Maine Public Broadcasting Network, WLBZ (Channel 2), WABI (Channel 5) and WVII (Channel 7) reported on an event held at the MDI Biological Laboratory in Bar Harbor on Aug. 4 where Sen. Susan Collins joined leaders from colleges and research institutions across Maine as well as dozens of Maine college students to celebrate the receipt of an $18.4 million grant from the National Institutes of Health. The five-year award aims to strengthen biomedical research and hands-on workforce training in Maine through the continuation of the Maine IDeA Network of Biomedical Research Excellence (INBRE), a collaborative network of 13 Maine research institutions, universities and colleges led by the MDI Biological Laboratory. The University of Maine and UMaine’s Honors College are part of the network. Anne Campbell, who graduated from UMaine in 2012 with degrees in chemistry and biochemistry, spoke with MPBN about her experience with the program. As a member of UMaine’s Honors College, she took a weeklong course at MDI Bio Lab on functional genomics, which was paid for by Maine INBRE. Campbell said during that course she met her thesis adviser, and was able to develop a thesis project. The Portland Press Herald carried the AP report.

Maine Edge Publishes Report on Extreme Weather Events Research

Tuesday, August 5th, 2014

The Maine Edge published a report about University of Maine scientists working with agencies to improve the accuracy of forecasts of hurricanes, superstorms, blizzards and floods that endanger people and animals and destroy property. UMaine received $1.5 million of the National Oceanic and Atmospheric Administration’s $5.5 million award to increase the precision of predictions of extreme weather events and coastal flooding in the northeastern United States. “This project allows us to develop rapid response capability and deploy ocean observing assets before extreme weather events, and use these targeted observations to constrain ocean models and issue timely forecasts for coastal cities and towns in the Northeast United States,” said Fei Chai, professor and director of UMaine’s School of Marine Sciences, and one of four university co-investigators taking part.
