Bend Science Pub to feature OSG invasive species educator

Posted on by

Science PubBEND – Oregon Sea Grant’s invasive species specialist, Sam Chan, is the featured speaker for the OSU Cascades Science Pub event on Tuesday, May 21 at McMenamins Old St. Francis School in Bend. The informal event runs from 5:30 to 7:30 p.m and features a full pub menu and no-host bar.

Chan, a Sea Grant Extension specialist and biologist with the OSU Institute for Water and Watersheds, will talk about how invasive species arrive in Oregon via land, air and sea, and can cause serious harm to our economy and environment.  Learn how these invaders arrive in ways we would never anticipate – through innocent classroom projects, gardening, and on floating tsunami debris – and what you can do to prevent and minimize their impact.  Chan’s research guided the creation of the award-winning statewide “Silent Invasion” program.

Use this online form to reserve a seat for Hitchhikers from Afar: Aquatic Invasive Species & You. Science Pubs are free but due to their popularity, reservations are required no later than 5:00 p.m. the day prior to each lecture.

Marina owners, users, team up to clear Fernridge lake of boat-fouling invader

Posted on by

Photo by Roger BaileyEUGENE –  The Fern Ridge Reservoir just west of Eugene, Ore., is a popular recreation spot for boaters and swimmers during the spring and summer months. The marina attracts freshwater sailors and provides ample fishing opportunities for anglers. There’s only one problem: An invasive species is steadily taking over the lake, and the worse it gets, the less welcoming the lake becomes.

The invader, known as Eurasian watermilfoil, is an aquatic plant that forms tangled mats as it grows. Eurasian watermilfoil tends to show up in shallow waters where it can access sunlight. These thick tangles are obstructive enough to stop boat motors from working, and they can prevent kayakers from maneuvering through the water.

Not only is the milfoil an obstacle, but it also saps oxygen from the water and can cause fish to suffocate. As the fish decay at the bottom of the lake, the smell can get pretty strong.

For boaters  like Scott Coleman, the owner of Underway LLC and manager for the Orchard Point Marina, it’s a worrying problem. “Specifically in this marina, if this plant really got going and clogged up the marina, then you wouldn’t be able to get your boat through here,” Coleman says. “And, it would be no fun to swim in.”

Last year, Coleman and a band of concerned marina users decided to take action. After consulting with Tania Siemens, WISE Program coordinator, and Sam Chan, invasive species specialist at Oregon Sea Grant, the boaters created a management plan that could correct their core problem: standing water.

Audubon highlights OSG’s work to educate about marine invaders

Red-eared slider, another classroom invader

The latest issue of Audubon, the magazine of the National Audobon Society, reports that in the 1970s an Alaskan high school science teacher purchased red-legged frogs from a supply house in the Pacific Northwest. Once the amphibians were no longer needed, the educator released them. Four decades later, studies show that frogs that have decimated local Alaskan amphibian populations have genetic ties to those found in Washington’s Columbia Basin. …

Oregon Sea Grant Extension specialist Sam Chan, a biologist who researches invasive species at Oregon State University, is leading a collaborative project with U.S. and Canadian researchers to educate teachers about the dangers of letting aliens loose. In one survey of nearly 2,000 teachers, Chan’s team found that schools had released dozens of well-known invasive species, like crayfish, waterweeds, mosquito fish, and red-eared slider turtles (above).

Science on Tap: Dan Bottom on sustaining salmon

Posted on by

Dan BottomNEWPORT – Dan Bottom, fisheries biologist with NOAA’s Northwest Fisheries Science Center, steps up to the bar to talk about salmon at the next Science on Tap event on March 13 at Brewer’s on the Bay.

“Celebrating Diversity: Sustaining Pacific Salmon in a Changing World” is Bottom’s theme for the evening, which takes place in the downstairs Board room at Rogue Ale’s South Beach waterfront location. Doors open at 5:30 p.m. and the talk begins at 6; the event is free and open to the public. Appetizers will be served, and additional food and drinks available for purchase from the menu.

Bottom, editor and contributing author for Oregon Sea Grant’s 2011 book Pathways to Resilience: Sustaining Pacific Salmon in a Changing World, will discuss the importance of salmon diversity and the attributes of resilience. His talk will draw from the book’s 11 peer-reviewed articles, including case studies of salmon and salmon fisheries, and will explore management actions that draw on salmon life history and genetic diversity to maintain salmon populations into the future.

Bottom notes, “Salmon exhibit a wide variety of life history traits. These include salmon runs and populations that exhibit differences in migration timing, duration of estuary rearing and size when the salmon enter the ocean.” Healthy, diverse watersheds, says Bottom, provide habitat connections that not only sustain diverse salmon life histories but also provide diverse social and economic opportunities for people.

The 392-page, full-color book, with a prologue by Governor John Kitzhaber, will be available at the event for purchase and author signing. It can also be purchased online from Oregon Sea Grant.

Science on Tap is a regular program of OSU’s Hatfield Marine Science Center, co-sponsored by Oregon Sea Grant, NOAA, the Pacific States Marine Fisheries Commission, MidCoast Watersheds Council, Native Fish Society, and The Wetlands Conservancy. For more information about the event, call 541-867-0234.

Tsunami dock piece to be dedicated March 10

Cleaning the tsunami dock (Photo: OSU Hatfield Marine Science Center)NEWPORT – A new tsunami awareness exhibit, featuring a piece of the massive Japanese dock that washed ashore at Agate beach last year, will be dedicated at OSU’s Hatfield Marine Science Center in a public ceremony and grand opening on Sunday, March 10.

The public ceremony, which runs from 2-4 pm,  marks the two-year anniversary of the devastating earthquake and tsunami that hit northern Japan. Sponsors include Oregon Sea Grant, the HMSC and the City of Newport.

The dock was among the first – and largest – fragments of debris to wash up on Pacific Northwest shores more than a year after the magnitude 9.03 undersea megathrust earthquake off the coast of Japan on March 11, 2011. The dock’s arrival on Agate Beach last June, sparked concern over the potential spread of non-native plants and marine animals, thousands of which were found alive and clinging to the dock.

Teams of state Parks and Recreation workers, scientists and volunteers scoured the dock’s surface and scorched it with blow-torches to destroy the organisms – and also collected specimens for identification and analysis by researchers at the HMSC.

The dock, roughly the size of a railroad boxcar and weighing tons, was sawn into pieces for disposal, and one section was saved to be placed at the Hatfield Center as a memorial to the Japanese disaster – and to aid in educating visitors about the risks of similar tsunamis generated by subduction zone quakes off the Oregon coast.  On initial delivery, however, the concrete-and-steel segment was discovered to be too big for its site, and was hauled to the Port of Newport docks to be recut to fit the space.

Oregon Sea Grant publishes booklet on drinking-water systems in coastal Oregon

Posted on by

The following publication is available as a free download from Oregon Sea Grant.

The print version may be purchased from Oregon Sea Grant’s e-commerce store.

Planning for Resilience in Oregon’s Coastal Drinking Water Systems

On Oregon’s rugged coast, large-scale infrastructure for public utilities is virtually nonexistent, meaning that drinking water must be obtained through small systems, domestic wells, or springs. While a portion of Oregon’s coastal population utilizes a domestic or private source, the vast majority of residents rely on small public systems for their drinking water. Unfortunately, risks associated with small drinking-water systems are not widely documented nor well understood.

Planning for Resilience in Oregon’s Coastal Drinking Water Systems is the result of case studies of 13 drinking-water sytems in coastal Oregon. It examines risks to these systems including infrastructure issues, contamination, climate change, earthquakes, and tsunamis, and explores actions to increase resilience, such as planning, backup supply, source water protection, infrastructure improvements, and communication. The publication will be of value to coastal water system managers, city planners, and coastal residents interested in water supply issues.

 

Washington state declares war on ocean acidification

Posted on by

Washington state, the leading US producer of farmed shellfish, this week launched a 42-step plan to reduce ocean acidification. The initiative — detailed in a report by a governor-appointed panel of scientists, policy-makers and shellfish industry representatives — marks the first US state-funded effort to tackle ocean acidification, a growing problem for both the region and the globe.

The state governor Christine Gregoire,  says she will allocate $3.3 million to back the panel’s priority recommendations.

“Washington is clearly in the lead with respect to ocean acidification,” says Jane Lubchenco, administrator of the US National Oceanic and Atmospheric Administration (NOAA).

As growing carbon dioxide gas emissions have dissolved into the world’s oceans, the average acidity of the waters has increased by 30% since 1750. Washington, which produces farmed oysters, clams and mussels, is particularly vulnerable to acidification, for two reasons: seasonal, wind-driven upwelling events bring low-pH waters from the deep ocean towards the shore, and land-based nutrient runoff from farming fuels algal growth, which also lowers pH.

Rising stream temperatures could spell trouble for salmon

Posted on by

A newly published study by researchers at Oregon State University and two federal agencies concludes that high temperatures coupled with lower flows in many Northwest streams is creating increasingly extreme conditions that could spell trouble for salmon and other organisms.

The study, published in the professional journal Hydrobiologia, was funded and coordinated by the U.S. Geological Survey and the research branch of the U.S. Forest Service. It points to climate change as the primary cause.

“The highest temperatures for streams generally occur in August, while lowest flows take place in the early fall,” said Ivan Arismendi, a research professor in OSU’s Department of Fisheries and Wildlife. “Each period is important because it is a time of potentially high stress on the organisms that live in the stream. If they occur closer in time – or together – they could create double trouble that may be greater than their combined singular effects.”

Public forum aims to demystify ocean acidification, hypoxia

Posted on by

How is Oregon's ocean affected by hypoxia and acidification?TILLAMOOK – Hypoxia and ocean acidification get a lot of press, but how many people know what these phenomena are, what causes them and what they mean for marine species and coastal communities? Now’s the chance to find out, in an Oct. 23 public forum that aims to take some of the mystery out of the science behind measuring, understanding and minimizing the effects of of these ocean conditions.

The forum, starting at 6:30 pm in rooms 214-215 at Tillamook Bay Community College, 4301 3rd St., is free and open to the public. Pre-registration is encouraged, but not required. For more information, visit the PISCO Website.

Organized by the Partnership for Interdisciplinary Studies of the Ocean (PISCO) and Oregon Sea Grant, the forum will focus on cutting edge research by scientists from many disciplines, and how resource managers and industries are responding.  A series of speakers will address:

  • The definitions of ocean acidification and coastal hypoxia, and how they are related – Francis Chan, OSU Zoology/PISCO
  • Why this is happening off our coast and what makes Oregon vulnerable – Burke Hales, OSU College of Earth, Ocean and Atmospheric Sciences (CEOAS).
  • How scientists are monitoring the ocean for these changes – Jack Barth (CEOAS/PISCO)
  • The impacts of acidification on shellfish hatcheries – Alan Barton (Whiskey Creek Shellfish Hatchery)

Speakers will be followed by a question-and-answer panel featuring scientists and representatives of the Oregon Department of Fish and Wildlife and the National Oceanic and Atmospheric Administration.

The event is hosted by PISCO through funding from Oregon Sea Grant.
