When Oregon’s legislative session kicks off in January, a doctoral student in environmental science will be providing lawmakers with information on marine and coastal issues, thanks to funding from Oregon Sea Grant.

As a recipient of Oregon Sea Grant’s 2019 Legislative Fellowship, Valerie Stephan-LeBoeuf will be assigned to the office of Rep. David Brock Smith, the incoming chair of the Coastal Caucus.

Among her duties, she will organize weekly meetings of the Caucus, research legislation that affects marine resources and the Oregon coast, and report on the progress and outcomes of marine and coastal issues addressed during the session.

The Idaho native started her fellowship on Nov. 1 and is based in Salem. She plans to continue her studies during the fellowship, which runs through June 30 when the legislative session ends. She is pursuing a doctorate at the University of Idaho, where she is studying restoration efforts for sea otters along the Oregon coast.

“This fellowship opportunity will not only enhance my understanding of the legislative process in Oregon, but will also provide valuable networking opportunities that will enrich my future graduate studies and professional career,” Stephan-LeBoeuf said.

A former zookeeper, Stephan-LeBoeuf also spent 10 years rehabilitating and releasing wildlife, including bears and cougars. She has also worked as an educator and facilitator for human-wildlife conflict resolution, focusing on humane and sustainable solutions to environmental issues. She earned a bachelor’s degree in psychology with a minor in paralegal studies from Boise State University, a master’s in education from Concordia University, and a master’s in environmental science from the University of Idaho.

“I am specifically interested in the management of marine mammals, and in the use of methods that integrate collaboration with stakeholders during policy development and review,” Stephan-LeBoeuf said.

“Valerie’s strong interpersonal skills complement her experience with navigating key natural resource issues,” said Sarah Kolesar, the leader of Oregon Sea Grant’s research and scholars program. “Working with coastal lawmakers will provide her additional experience with marine and ocean topics. Her excellent work ethic makes her a valuable asset for the Caucus.”

Each legislative session, Oregon Sea Grant sponsors one Fellow. The goal is not only to help lawmakers but to help the recipient understand the legislative process and develop skills for collaborating with government and other organizations. Fellows receive a competitive monthly stipend. They do not assume a political position or lobby on any issue.

The next application deadline will be in August 2019 (date TBA). Applicants must be enrolled in a master’s, doctorate, or professional degree program (e.g., law school) in any discipline at an institution of higher education with work physically located in Oregon, or have completed their degree after December 2017. Women and minorities are encouraged to apply.

Former OSU student helps Portland brewery win pollution prevention award

Posted by: | October 25, 2018 Comments Off on Former OSU student helps Portland brewery win pollution prevention award |

10-25-18

By Rick Cooper

Portland’s Widmer Brothers Brewing has won a national award for pollution prevention, thanks in part to an intern who was an engineering student at Oregon State University at the time.

Alan Haynes, a summer 2017 intern with Oregon Sea Grant’s Oregon Applied Sustainability Experience program, helped the craft brewery win the 2018 Most Valuable Pollution Prevention Project award from the National Pollution Prevention Roundtable.

Haynes graduated from OSU’s School of Chemical, Biological and Environmental Engineering in 2018.

“The work kicked off by the pollution prevention internship led to significant, measurable impacts on the brewery and as a result, cleaner wastewater is being discharged,” said Julia Person, Widmer Brothers Brewing’s sustainability manager.

She said that Haynes and the brewery team explored ways to reduce biological oxygen demand (BOD) and total suspended solids (TSS), regulated wastewater pollutants. BOD and TSS in breweries result from excess yeast, grain or hops that find their way to the drain. The goal was to find methods that saved on extra-strength sewer charges resulting from the BOD and TSS in the brewery’s wastewater discharge.

“Everyone across the brewery was engaged to help identify areas of waste and improvement opportunities,” Person said. “Alan identified the appropriate technology to implement the solutions and ran the numbers on the return on investment for each.”

“My main focus,” Haynes said, “was to ensure that there was a strong financial argument for implementation, which included researching available technologies and building tools to help model the impact on wastewater charges if they were installed.”

The project resulted in changes in equipment and processes that helped reduce Widmer’s annual biological oxygen demand by 11 percent (10,000 pounds) and total suspended solid waste by 60 percent (6,000 pounds), Person said. The improvements will save the brewery more than $150,000 a year, she said.

The addition of a pump to divert high-TSS liquids from spent grain was the main contributor to the savings. Other innovations resulting from the project include testing at key process points such as tank cleaning, yeast harvesting and kegging, and preventing overflow of a waste yeast capture system. This waste yeast is now hauled to regional dairy farms and used in feed.

Haynes, who is seeking employment in the Portland metro area, said that because he had little background in wastewater processes, it was a challenge to get up to speed on brewery terminology and chemistry while working to identify promising areas to focus on. But the challenge was tempered by Widmer’s “extremely welcoming and friendly” work environment and helpful brewers and engineers, he said. “They made a point of ensuring I was treated as a valuable member of the team and not just another intern.”

The internship program that Haynes took part in is a partnership with Oregon Sea Grant and Oregon’s Department of Environmental Quality (DEQ). Funded by the Environmental Protection Agency and launched in 2017, it provides paid 10-week summer internships. Undergraduate and graduate students in Oregon are matched with businesses in the state to help them reduce toxic chemicals, energy, water use and waste.

The first cohort interned at five companies. If those businesses were to implement the interns’ recommendations, they could annually save nearly $900,000, reduce water use by 60 million gallons, and decrease solid or hazardous materials by 8.5 tons, according to DEQ’s website.

Information on how to apply to be an intern next summer will be announced in early 2019.

PHILOMATH, Ore. – A new self-guided, clue-driven walking tour near Philomath explores the history of a 157-year-old cemetery founded on land donated by a former slave.

The walk, which is part of Oregon Sea Grant’s Quests program, takes place on the 6.7-acre Mt. Union Cemetery where about 2,500 people are buried on a gently sloping hillside. The cemetery was created on May 11, 1861 – one month after the American Civil War started.

Reuben Shipley, who earned his freedom by driving his owner’s oxen from Missouri to Oregon in 1853, donated two acres of his farm to establish the cemetery on the condition that black people could be buried there. Shipley, his wife and six children were the only black family in Benton County at the time, according to the cemetery’s website.

Cait Goodwin, an educator with Oregon Sea Grant and the coordinator of its Quests program, said those who complete the walk will become more familiar with the site’s history and the story of Shipley and others who are buried there.

Goodwin also explained that Quests are self-guided learning adventures that use clues and hints to encourage participants to discover the natural, cultural and historical treasures of a place. At the end of each tour, participants find a hidden box containing a logbook to sign and a stamp to mark their accomplishment. Quests are suitable, she said, for individuals, families and groups of all ages who wish to explore parks, trails and other outdoor spaces at their own pace.

“Going on the Mt. Union Cemetery Quest provides an opportunity to explore the early contributions of persons of color in our community,” said Ann Bateman, a member of the cemetery’s board of trustees. “People who’ve taken the Quest say they want to go back and explore some more.”

The Quest can be found at bit.ly/mtunioncemeteryquest. It was created by Ginny Weeber of Redmond and her granddaughter Kyah Weeber of Philomath, in partnership with Oregon Sea Grant and the Mt. Union Cemetery Association. It is the third cemetery Quest in the program, joining one in Lincoln City and another in Newport. Participants will traverse grassy and gravel surfaces and need about 30 minutes to complete the walk.

The Mt. Union Cemetery Quest is slated to appear in the next edition of Oregon Sea Grant’s Oregon Coast Quests Book. To learn more about Quests and where to obtain the books, visit hmsc.oregonstate.edu/quests.

The cemetery is at 2987 Mt. Union Ave. just outside the eastern city limit of Philomath. It is open during daylight hours.

OSU gets two NOAA aquaculture grants to help oyster industry and marine fish hatcheries

Posted by: | November 7, 2017 Comments Off on OSU gets two NOAA aquaculture grants to help oyster industry and marine fish hatcheries |

11/7/17

by Tiffany Woods

The National Oceanic and Atmospheric Administration (NOAA) has awarded scientists at Oregon State University two aquaculture grants that aim to make oysters safer to eat and help hatcheries feed certain marine fish more efficiently.

The first project, funded at $150,000, aims to reduce bacteria known as Vibrio parahaemolyticus in oysters without altering their texture and consistency. Researchers plan to add naturally occurring marine probiotics, which are live or freeze-dried microbial supplements, to the seawater in depuration tanks. Depuration tanks are where oysters are sometimes held to flush out contaminants that may be in their tissues. Researchers have already isolated various marine probiotics that inhibit the growth of pathogens.

The researchers also aim to develop a dipstick containing antibodies to quickly screen adult oysters for V. parahaemolyticus. The idea is that people would not need special training or equipment to use this diagnostic tool.

The leader of this two-year project is Shelby Walker, the director of Oregon Sea Grant, although the actual research will be conducted by the lab of Claudia Hase, a professor with OSU’s College of Veterinary Medicine. Partners include mAbDx, an immunodiagnostics company in Eugene, Ore.; and Reed Mariculture near San Francisco.

The other grant, worth $629,000, aims to improve the nutritional value of live prey fed to California halibut, California yellowtail and southern flounder. When they’re still in their larval stage, farmed saltwater fish are typically fed tiny rotifers and brine shrimp. However, these organisms are less nutritious than copepods, which are the natural prey of many marine fish in the wild. Given this, the researchers plan to feed rotifers and brine shrimp vitamin C and taurine, an amino acid. To make sure these nutrients don’t dissolve in the seawater, the researchers will encapsulate them in bubble-like liposomes, which can have impermeable membranes.

The researchers plan to:

  • determine the optimal concentrations that should be used for taurine and vitamin C,
  • evaluate how these nutrients affect the growth, survival and stress resistance of the fish,
  • develop methods to produce the liposomes on a larger scale instead of just at the laboratory level,
  • study how long-term storage affects how the liposomes retain the nutrients, and
  • determine how much it would cost to produce and store liposomes and how many liposomes would be needed to feed a certain amount of prey.

Walker will lead the three-year project, but the research will be conducted by the lab of Chris Langdon, a professor with OSU’s Department of Fisheries and Wildlife, and well as by staff at the subcontracted Hubbs-SeaWorld Research Institute in San Diego. Partners include the Texas Parks and Wildlife Department and Reed Mariculture. Bill Hanshumaker, a marine educator with Oregon Sea Grant Extension, will be involved with outreach activities.

Oregon Sea Grant will administer the funding for both projects. They are part of 32 grants totaling $9.3 million awarded by NOAA last week to further develop the nation’s marine aquaculture industry.

“This country, with its abundant coastline, should not have to import billions of pounds of seafood each year,” said Secretary of Commerce Wilbur Ross. “These grants will promote aquaculture projects that will help us reduce our trade deficit in this key industry.”

All projects include public-private partnerships and will be led by university-based Sea Grant programs.

“Industry is working alongside researchers on each of these projects, which will help expand businesses, create new jobs and provide economic benefits to coastal communities,” said Jonathan Pennock, the director of NOAA Sea Grant.

NOAA received 126 proposals requesting about $58 million in federal funds.
