Student ROV design and engineering regionals set for May 4

Posted by: | April 29, 2013 Comments Off |

Student launches an ROV during last year's Oregon Regional competitionLINCOLN City – More than 100 junior high, high school and college students will converge on the Lincoln Community Center this Saturday (May 4) to compete in the Oregon Regional Marine Advanced Technology ROV Competition – and a chance to advance to the international finals.

Teams from Albany, Astoria, Corbett, Corvallis, The Dalles, Eddyville, Lincoln City, Salem, Toledo, Portland and Waldport are expected for the competition which runs from 8:30 am to 4:30 p.m. at the community center, 2150 NE Oar Place. The event is open to the public.

Competing teams, ranging from 6th grade to college age, have designed and built tethered underwater robots known as remotely operated vehicles, or ROVs. The annual competition is sponsored by Oregon Sea Grant, the OregonCoast STEM Center, and the Oregon Chapter of the Marine Technology Society, and is intended to encourage Oregon students to learn and apply science, technology, engineering and math skills.

Full-scale ROVs are widely used in scientific research,  ocean exploration, homeland security, the offshore oil and gas industry, and other industries.  This year’s contest highlights the role ROVs play in the installation, operation, and maintenance of ocean observing systems,  collections of high-tech instruments above and below the waves that provide around-the-clock information about what is happening in the ocean. Via fiber optic cable, the data collection equipment continuously communicates information to scientists, engineers and technicians who use it to understand and make predictions about the ocean, coast, and ocean resources. Ocean Observing Systems provide critical information on climate change, toxic algal blooms, tsunamis and other ocean hazards.

Competing teams must pilot their ROVs to perform a variety of underwater mission tasks, from installing a simulated power and communications “hub” and scientific instruments in order to complete a seafloor ocean observatory to removing bio-fouling organisms from instruments and performing maintenance on moorings.

The winning team will advance to the 12th annual MATE International ROV Competition, June 20-22 in Federal Way, Wash.

The regional MATE program, one of 22 such competitions around the world, is supported by local sponsors including the Marine Technology Society, the Oregon Coast Regional STEM Center, OSU’s Pre-College Programs, Northwest Aquatic and Marine Educators, the Siletz Tribe Charitable Funds, the Oregon Coast Aquarium, Pro-Build, Advanced Research Corporation, and the NOAA Officers Family Association. Local marine technology professionals volunteer as judges for the competition, evaluating the students’ ROVs, poster displays, and engineering presentations.

Oplegnathus-fasciatus-WDFW-photox250Scientists at Oregon State University’s Hatfield Marine Science Center are examining a handful of Japanese fish that may have survived a nearly two-year trip aboard a small fishing boat torn off the Japanese coast by the 2011 tsunami.

The fish – Oplegnathus fasciatus, known as Barred knifejaw or Striped beakperch – were found in the bottom of a Japanese boat that washed ashore at Long Beach, WA on March 22. The vessel is one of a growing number of large items cast to sea by the Japanese tsunami that have made their way across the ocean to Pacific Northwest shores.

Sam Chan, Oregon Sea Grant’s invasive species specialist, said the fish species normally are found only as far east as Hawaii. Scientists aren’t yet sure whether the fish traveled all the way from Japan, or if they somehow got onboard the derelict vessel as it crossed the ocean. “Either way, it’s an interesting case of organisms ‘rafting’ across the ocean,” Chan said.

OSU’s Jessica Miller, a marine fisheries ecologist with the HMSC-based Coastal Oregon Marine Experiment Station, as four of the fish and is examining their stomach contents and otoliths (specialized bones found in the ears of fish and other species) for insight into what the fish had been eating and the environmental conditions they encountered during their transit. The fifth fish is on display at the Seaside Aquarium.

Explore behind the scenes at HMSC Marine Science Day

Posted by: | April 1, 2013 Comments Off |

NEWPORT, Ore. – Oregon State University’s Hatfield Marine Science Center invites public to explore its marine science labs and Visitor Center,  “behind the scenes”  on Saturday, April 13, when the Newport facility hosts its annual Marine Science Day.

The free event, which runs from 10 a.m. to 4 p.m., will feature scientists and educators from OSU, Oregon Sea Grant, federal and state agencies, Oregon Coast Aquarium, and the nearby NOAA Marine Operations Center-Pacific. It is a chance for the public to explore one of the nation’s leading marine science and education centers.

An full schedule of events is available at: hmsc.oregonstate.edu/marinescienceday

In addition to a varietyof marine science presentations, two research themes will be highlighted. One is the science behind bycatch reduction devices, which will be featured by researchers from NOAA Fisheries, Oregon Department of Fish and Wildlife, OSU, Pacific States Marine Fisheries Commission, and Foulweather Trawl, a Newport netmaker.

Marine Science Day visitors will see actual bycatch reduction devices and have an opportunity to view videos showing how fish are excluded or retained, depending on their size, swimming ability or other characteristic. Other research will highlight genetics or other tools used to distinguish between wanted and unwanted catch. Scientists will be on hand to answer questions and discuss their research.

“Visitors will learn not only about the problem of bycatch but also about the solutions, which range from simple and elegant to complex and cutting-edge,” said Maryann Bozza, program manager of the center. “All of the different HMSC research displays on bycatch reduction will be grouped together.”

A second theme will be wave energy, highlighting the efforts of the OSU Northwest National Marine Renewable Energy Center to improve and facilitate testing of wave energy devices and evaluate their potential effects on marine habitats. HMSC’s Sarah Henkel, a senior research assistant professor in the OSU Department of Zoology, will present an update of wave energy developments on the Oregon Coast.

Henkel’s talk begins at 3 p.m. in the Visitor Center auditorium.

Among other highlights of Marine Science Day:

  • Visitor Center activities will include new wave energy exhibits, the recently dedicated Japanese tsunami dock exhibit and a new interactive wave tank.
  • The center’s new octopus, named “Miss Oscar,” will be featured in a 1 p.m. interpretive talk and octopus feeding demonstration.
  • Visitors can take self-guided tours through the facility’s marine research labs, library and classrooms, where scientists will have interactive exhibits explaining their research. Guided tours of HMSC’s seawater facilities and aquatic animal husbandry laboratory will also be offered.

A number of educational activities for children and families will be available, presented by Oregon Sea Grant, U.S. Fish and Wildlife Service and the Oregon Coast Aquarium.

The OSU Hatfield Marine Science Center is located at 2030 S.E. Marine Science Drive in Newport, just south of the Highway 101 bridge over Yaquina Bay.

Science on Tap: Dan Bottom on sustaining salmon

Posted by: | March 6, 2013 Comments Off |

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.

Clever video aims to reduce rockfish deaths from barotrauma

Posted by: | February 13, 2013 Comments Off |

This clever video  uses a catchy rap tune, a wise-cracking puppet and some simple, practical instructions to engage fishermen in protecting rockfish from dying of barotrauma, by reaching them how to return their excess catch to the deeps – alive.

Barotrauma results when a rockfish is caught and hauled rapidly to the surface and its internal, air-filled swim bladder expands, often causing the animal’s eyes to bulge and even pushing its stomach out of its mouth. If thrown back in the water, the inflated bladder can cause the fish to float, making it easy prey for seabirds and other hungry animals.

But if the animal can be returned to the deeps quickly, water pressure will often reverse the expansion, allowing the  fish to survive. The video demonstrates a number of effective tools – home-made and commercial – for getting the fish back to the bottom quickly and with as little harm as possible.

The video, funded in part by California Sea Grant, was produced by a team including Alena Pribyl, a NOAA Southwest Fisheries Science Center researcher who earned her PhD. at Oregon State University while studying barotrauma.

Magnetic navigation may hold a key to salmon migration

Posted by: | February 11, 2013 Comments Off |

Salmon - photo by Jeffrey BasingerAfter years at sea, sockeye salmon returning to their freshwater homes may be guided by an early memory of the Earth’s magnetic field, encoded at the site where natal streams empty into the Pacific Ocean, according to a an Oregon Sea Grant-supported study published today in Current Biology.

Oregon State University’s Nathan Putnam and David Noakes, along with researchers from the University of North Carolina Chapel Hill, the University of Washington, and the University of California Davis, pored over 56 years of dta from federal fishery scientists who tracked the movements of salmon at the mouth of British Columbia’s Fraser River, where fish must choose to swim north around Vancouver Island, or around to the south. They matched that data with  measurements of the Earth’s geomagnetic field, which shifts predictably in strength and orientation over time and found that fish tended to choose the path where the field strength was more similar to that of the river mouth when they’d left, two years before.

Scientists hope the finding will help solve the mystery of how salmon find their way back to the rivers of their birth across thousands of miles of ocean. It’s already accepted that in the final stages of the journey to their breeding grounds, salmon use odors to guide them back to the stream or inlet where they hatched. But how the fish find their target river remains a mystery, although scientists have suspected for a while that magnetic cues play a role. Last summer, a team including UNC-Chapel Hill researcher Kenneth Lohmann – also part of this study – reported that rotating magnetite crystals in a fish nose responded to magnetic field orientation, providing a possible biological mechanism for magnetic field tracking.

The OSU researchers hope to further investigate the magnetic field correlation by subjecting captive fish to artificial magnetic fields and studying their behavior.

OSU to take lead in designing new NSF research ships

Posted by: | January 31, 2013 Comments Off |

R/V Oceanus, OSU's current primary research vesselOregon State University has been chosen to lead a project to design and build as many as three new coastal research vessels, the first multi-ship expansion of the National Science Foundation’s academic research fleet since the 1970s, and one intended to boost the marine science research capabilities of the United States.

The new vessels, which could take a decade to design, build and equip, will become part of the University-National Oceanographic Laboratory System, the nationwide program which provides research-capable ships to universities which could not afford to build and own the vessels themselves in order to advance the nation’s marine science capacity.

OSU initially will receive nearly $3 million to coordinate the design phase of the project – and if funds are appropriated for all three vessels, the total grant is projected to reach $290 million over 10 years. The first phase of the project is scheduled to begin early this year. The final number of ships constructed, and where the vessels will be berthed, will be determined by the NSF based on geographic scientific requirements and availability of funding.

If all three vessels are built, it is likely that one each would be positioned on the East Coast, West Coast and Gulf Coast, officials say. As part of its proposal to lead the effort, OSU proposed to be the operator of the first vessel.

Distributing the vessels geographically allows scientists from all over the country to book research cruise time from locations nearest to the ocean and coastal areas they are studying.

The university now operates the R/V Oceanus, which replaced the R/V Wecoma when it was retired from service last year and sent away to be scrapped. Both vessels dated to the mid 1970s, and the Oceanus is expected to be ready for retirement about the time the new research vessels become available.

A project team led by Oregon State’s College of Earth, Ocean, and Atmospheric Sciences will finalize the design for the 175-foot long, technically enhanced Regional Class ships, select a shipyard, oversee construction, and coordinate the system integration, testing, commissioning and acceptance, and transition to operations.

“These will be floating, multi-use laboratories that are flexible and can be adapted for different scientific purposes, yet are more seaworthy and environmentally ‘green’ than previous research vessels,” said Mark Abbott, dean of the OSU College of Earth, Ocean, and Atmospheric Sciences. “These ships will be used to address critical issues related to climate change, ocean circulation, natural hazards, human health, and marine ecosystems.”

OSU vice president for research Rick Spinrad, who previously directed research programs for the U.S. Navy and the National Oceanic and Atmospheric Administration (NOAA), said the new vessels would “revitalize and transform” coastal ocean science in the United States.

“Many of the most pressing issues facing our oceans are in these coastal regions, including acidification, hypoxia, tsunami prediction, declining fisheries, and harmful algal blooms,” Spinrad said. “Because of their flexibility, these new vessels will attract a broad range of users and will become ideal platforms to training early-career scientists and mariners.”

The project had the support of Oregon Gov. John Kitzhaber’s Office, noted OSU President Ed Ray, who said the university will benefit from the process long before the first ship hits the water in 2019 or 2020.

The successful OSU proposal was submitted to the National Science Foundation by Clare Reimers, an oceanography professor, and Demian Bailey, the university’s marine superintendent. As part of that submission, OSU proposed to be the operator of the first vessel. Additional operating institutions will be determined once the total number of vessels to be built is known.

“The National Science Foundation hasn’t authorized a multi-ship project since the 1970s,” Bailey said, “and these are likely the only ships scheduled by NSF to be built during the next decade – so this is a big deal. The endurance and size of the new ships will be similar to that of Oceanus and Wecoma but they will be much more efficient and have far greater scientific capacity and flexibility.”

Washington state declares war on ocean acidification

Posted by: | November 28, 2012 Comments Off |

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.

Traces of Fukushima radiation found in Pacific albacore

Posted by: | October 24, 2012 Comments Off |

Researcher Delvan Neville labels containers of albacore tuna samplesCORVALLIS, Ore. – Samples of albacore tuna caught off the West Coast of the United States show minute traces of radiation that can be traced to the Fukushima reactor disaster, according to an interdisciplinary team of scientists from Oregon State University and the National Oceanic and Atmospheric Administration.

The radiation levels in fish analyzed to date are far below anything that would pose a risk to humans who consume the fish, the research team emphasized. The findings are preliminary; additional fish remain to be tested.

But the findings could reveal new information about where Pacific albacore travel during their migratory lives – and how what happens in one part of the ocean can affect the food web thousands of miles away.

The team has collected and tested fish caught off the U.S. West Coast both before and after the devastating March 2011 Japanese tsunami and subsequent release of radioactive material into the ocean by the Fukushima Daiichi nuclear reactor.

“We’re still processing new fish, but so far the radiation we’re detecting is far below the level of   concern for human safety,” said Delvan Neville, a graduate researcher with OSU’s Radiation Health Physics program and a co-investigator on the project.

People are constantly exposed to radiation from the natural environment, Neville pointed out. “To increase their normal annual dosage of radiation by just 1 percent, a person would have to eat more than 4,000 pounds of the highest (radiation) level albacore we’ve seen.”

Neville will present the team’s preliminary findings on Oct. 27 at the Heceta Head Coastal Conference in Florence. Richard Brodeur, the NOAA Northwest Fisheries Science Center biologist who serves as lead investigator on the project, reported the same findings to the recent annual meeting of  PICES, the North Pacific Marine Science Organization, in Japan. The researchers also plan scientific journal articles.

Public forum aims to demystify ocean acidification, hypoxia

Posted by: | October 18, 2012 Comments Off |

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.
