The Maine Edge published a report about an article in the Proceedings of the National Academy of Sciences (PNAS) that documents nearly 15 years of vernal pools research and management by the University of Maine’s Aram Calhoun who is leading an interdisciplinary team at the Sustainability Solutions Initiative (SSI), a program of the Sen. George J. Mitchell Center. In the article, Calhoun and three co-authors analyze a timeline of action and scholarship that spans from 1999 to the present. In that time, the professor of wetland ecology and director of UMaine’s Ecology and Environmental Sciences program has collaborated closely with academic colleagues, government at all levels, nongovernmental organizations, landowners, developers and concerned citizens in an effort to create an environment in which these small, but significant, wetlands can flourish.
All five of the Upward Bound Math Science student groups will present their final videos for the summer program’s Group Sustainability Design Project from 1:30 to 4:30 p.m. Friday, July 25, in the Foster Center for Student Innovation.
The Upward Bound Math Science Program is affiliated with the UMaine College of Education and Human Development and offers a six-week college preparatory program to first-generation college students from eight Maine high schools. The program specifically targets students who are interested in pursuing STEM (science, technology, engineering and mathematics) majors and careers.
This summer, 35 students are attending from Central High School in Corinth, Foxcroft Academy in Dover-Foxcroft, Mattanawcook Academy in Lincoln, Nokomis Regional High School in Newport, Oxford Hills Comprehensive High School in South Paris, Portland High School, Stearns High School in Millinocket, and Schenck High School in East Millinocket.
Students will present posters of their individual research projects and explorations completed over the summer from 5 to 9 p.m. Monday, July 28 in the atrium of the D.P. Corbett Business Building during the program’s conference-style STEM symposium.
University of Maine student Ray Peck spoke with Bill Green for a segment on WLBZ (Channel 2) about Maine’s declining heron population. This summer, Peck is assisting biologist Danielle D’Auria of Maine’s Department of Inland Fisheries and Wildlife. To study the birds, Peck and D’Auria are visiting dozens of heron colonies and monitoring bird behavior and reproductive rates. “There’s an aura to them — the way they act, the way they look,” Peck said. “They don’t look like they should be able to fly but they do. They’re really beautiful creatures; really amazing.”
Christopher Burns, a University of Maine student studying English, wrote an opinion piece for the Bangor Daily News, titled “Older adults have addictions, too. Is Maine ready to address the problem?” Lenard Kaye, director of the University of Maine Center on Aging and professor in the UMaine School of Social Work, was quoted in the op-ed. Burns is an intern at the BDN.
The Free Press reported spots are still available for Dive In, a two-day summer immersion program offered to college-bound high school students who are interested in marine sciences. The program, which will be held Aug. 4–5, will offer hands-on, field-oriented activities at the University of Maine Darling Marine Center in Walpole and the UMaine campus in Orono. It will showcase the university’s marine science faculty and facilities and the academic and research opportunities available to students.
Phys.org published a University of Maine report about UMaine oceanographer Ivona Cetinic participating in a NASA project that brings together marine and atmospheric scientists to tackle optical issues associated with satellite observations of phytoplankton. The goal is to better understand marine ecology and phytoplankton’s major role in the global cycling of atmospheric carbon between the ocean and the atmosphere. “Teams involved in this project are working together to develop next-generation tools that will change forever how we study oceans,” says Cetinic, a research associate at UMaine’s Darling Marine Center.
Erik Blomberg, an assistant professor of wildlife ecology in the Department of Wildlife, Fisheries and Conservation Biology at the University of Maine, received a $181,518 grant from the Maine Department of Inland Fisheries and Wildlife for his proposal, “Understanding population dynamics of ruffed grouse.”
The three-year project aims to better understand how forest management practices and sport hunting influence Maine’s ruffed grouse populations. According to the proposal, the native bird benefits from many forms of forest harvest and is widely used as a game species by Maine residents and visitors.
Blomberg and his team will implement a large-scale field study to evaluate how components of ruffed grouse biology, such as seasonal and annual survival and nest success, respond to different types of forest composition and management. Researchers also will estimate harvest rates throughout the annual hunting season from October to December.
Collected information will close a large gap in the current understanding of ruffed grouse ecology in the region and will contribute to future management of Maine’s popular game bird, as well as contribute to the general understanding of wildlife ecology in forest ecosystems, according to the researchers.
The researchers say they will work closely with the Maine Department of Inland Fisheries and Wildlife to ensure results provide the greatest benefit to Maine wildlife management.
University of Maine oceanographer Ivona Cetinic is participating in a NASA project to advance space-based capabilities for monitoring microscopic plants that form the base of the marine food chain.
Phytoplankton — tiny ocean plants that absorb carbon dioxide and deliver oxygen to Earth’s atmosphere — are key to the planet’s health. And NASA wants a clear, global view of them.
NASA’s Ship-Aircraft Bio-Optical Research (SABOR) mission will bring together marine and atmospheric scientists to tackle optical issues associated with satellite observations of phytoplankton.
The goal is to better understand marine ecology and phytoplankton’s major role in the global cycling of atmospheric carbon between the ocean and the atmosphere.
“Teams involved in this project are working together to develop next-generation tools that will change forever how we study oceans,” says Cetinic, a research associate at UMaine’s Darling Marine Center (DMC) in Walpole, Maine.
“Methods that will be developed during this experiment are something like 3-D glasses. They will allow us to see more details on the surface of the ocean and to see deeper into the ocean, helping us learn more about carbon in the ocean — carbon that is fueling oceanic ecosystems, as well as the fisheries and aquaculture.”
Cetinic will be a chief scientist aboard RV Endeavor that departs July 18 from Narragansett, Rhode Island. She received $1,043,662 from NASA’s Ocean Biology and Biogeochemistry program for her part in the three-year project.
Cetinic’s crew, which includes Wayne Slade of Sequoia Scientific, Inc., Nicole Poulton of Bigelow Laboratory for Ocean Sciences and UMaine Ph.D. student Alison Chase, will analyze water samples for carbon, as well as pump seawater continuously through on-board instruments to measure how ocean particles, including phytoplankton, interact with light.
Chase, who recently earned her master’s in oceanography at UMaine, will blog about the experience at earthobservatory.nasa.gov/blogs/fromthefield.
Interim DMC director Mary Jane Perry, who is participating in another research cruise this summer (umaine.edu/news/blog/2014/07/08/under-the-ice), will be involved in future data analysis.
Mike Behrenfeld of Oregon State University also will be aboard Endeavor and he and his team will use a new technique to directly measure phytoplankton biomass and photosynthesis.
“The goal is to develop mathematical relationships that allow scientists to calculate the biomass of the phytoplankton from optical signals measured from space, and thus to be able to monitor how ocean phytoplankton change from year to year and figure out what causes these changes,” he says.
Another research team also will be aboard Endeavor, which for three weeks will cruise through a range of ecosystems between the East Coast and Bahamas.
Alex Gilerson of City College of New York will lead a crew that will operate an array of instruments, including an underwater video camera equipped with polarization vision. It will continuously measure key characteristics of the sky and the water.
The measurements taken from aboard the ship will provide an up-close perspective and validate measurements taken simultaneously by scientists in aircraft.
NASA’s UC-12 airborne laboratory, based at NASA’s Langley Research Center in Hampton, Virginia, will make coordinated science flights beginning July 20.
One obstacle in observing marine ecosystems from space is that atmospheric particles interfere with measurements. Brian Cairns of NASA’s Goddard Institute for Space Studies in New York will lead an aircraft team with a polarimeter instrument to address the issue.
From an altitude of about 30,000 feet, the instrument will measure properties of reflected light, including brightness and magnitude of polarization. These measurements will define the concentration, size, shape and composition of particles in the atmosphere.
Polarimeter measurements of reflected light should provide valuable context for data from another instrument on the UC-12 designed to reveal how plankton and optical properties vary with water depth.
Chris Hostetler of Langley is leading that group. He and others will test a prototype lidar (light detection and ranging) system — the High Spectral Resolution Lidar-1 (HSRL-1). A laser that will probe the ocean to a depth of about 160 feet should reveal how phytoplankton concentrations change with depth, along with the amount of light available for photosynthesis.
Phytoplankton largely drive the functioning of ocean ecosystems and knowledge of their vertical distribution is needed to understand their productivity. This knowledge will allow NASA scientists to improve satellite-based estimates of how much atmospheric carbon dioxide is absorbed by the ocean.
NASA satellites contributing to SABOR are the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO), which view clouds and tiny particles in Earth’s atmosphere, as well as the Terra and Aqua satellites, which measure atmospheric, land and marine processes.
Analysis of data collected from the ship, aircraft and satellites is expected to guide preparation for a new, advanced ocean satellite mission — Pre-Aerosol, Clouds, and ocean Ecosystem (PACE), according to NASA.
PACE will extend observations of ocean ecology, biogeochemical cycling and ocean productivity begun by NASA in the late 1970s with the Coastal Zone Color Scanner and continued with the Sea-viewing Wide Field-of-view-Sensor (SeaWiFS) and the Moderate Resolution Imaging Spectroradiometer (MODIS) instruments on Terra and Aqua.
SABOR is funded by the Earth Science Division in the Science Mission Directorate at NASA Headquarters.

A WLBZ (Channel 2) report on the economic impact of Maine craft breweries on local communities cited several University of Maine studies. The report states that according to UMaine economic impact studies, Maine’s wild blueberry harvest was worth about $69 million in 2012, and the lobster catch was worth about $340 million. A study conducted by UMaine and the Maine Brewers’ Guild found the state’s craft brewing industry has an economic impact of nearly $200 million and is growing. The study looked at Maine’s 35 craft breweries in 2013. Now there are 55 breweries, with three more scheduled to open this year, according to the report.
Robert Lilieholm, the E.L. Giddings professor of forest policy at the University of Maine, wrote the opinion piece, “Bay to Baxter: As the Penobscot River changes, so must we,” for the Bangor Daily News.
