Marine Science Day opens HMSC labs to visitors

Posted on by

Pearl, the HMSC Visitor Center's newest octopusNEWPORT – OSU’s Hatfield Marine Science Center will open its doors a bit wider on Saturday, April 14, when the Newport facility hosts its first Marine Science Day.

The free public event, which runs from 10 a.m. to 4 p.m., will feature scientists and educators from OSU, federal and state agencies, the Oregon Coast Aquarium, and the new NOAA Marine Operations Center-Pacific. It offers a rare opportunity for the public to go behind the scenes of one of the nation’s leading marine science and education facilities.

Oregon Sea Grant and its marine education program will offer special activities at the HMSC Visitor Center, and behind-the-scenes tours of its ornamental fish laboratory.

Oregon First Lady Cylvia Hayes will speak briefly at 3 p.m. in the Visitor Center auditorium, along with OSU Vice President for Research Richard Spinrad. Bruce Mate, director of OSU’s Marine Mammal Institute, will follow with a presentation showcasing the center’s pioneering role in tracking whales by satellite.

“Marine Science Day will be fun and engaging for people of all ages,” said Maryann Bozza, HMSC program manager. “Visitors will wind through the campus, getting a true behind-the-scenes experience with an unparalleled opportunity to learn directly from marine scientists.”

Most Marine Science Day exhibits and activities will be indoors, but some tours will take visitors outside to walk from one lab to another, and some exhibits will be outdoors.

“The diverse science conducted at the facility reaches from local coastlines and estuaries to the depths of the world’s oceans,” she added, “and in scale from microbes on the seafloor to undersea volcanoes and the whales that swim over them.”

Visitors can meet Pearl, the Visitor Center’s newest octopus and watch her being fed at 1 pm; observe a sea turtle necropsy; and meet fisheries scientists and geologists whose research is described in center exhibits. The public also can participate in self-guided tours through the facility’s marine research labs, library and classrooms, where scientists will have interactive exhibits explaining their research. Highlights include:

  • Hear volcanoes erupt and whales ‘sing’ in an audio display by NOAA and OSU researchers using undersea hydrophones
  • Learn how researchers are supporting sustainable fisheries through innovative, collaborative research
  • Collect biological data from fish, plankton and even a shrimp parasite through hands-on experimentation
  • Explore novel oceangoing and ocean floor instrument platforms and meet the scientists who designed them.

Visitors may also take guided tours of HMSC’s seawater facilities and ornamental fish laboratory. More information, including program and special events, is available at on the HMSC Website.

The event is intended to showcase OSU’s unique partnership with state and federal agencies, which makes the HMSC a national leader in marine research and education, according to director George Boehlert.

“OSU’s Newport campus is known for a diversity of research and the expertise of its scientists, which offer unique opportunities in education and outreach,” Boehlert said. “Visitors to Marine Science Day will get a sense of the innovation and synergy that makes the Hatfield Marine Science Center unique.”

Collaborative research partners that share the campus with OSU labs include six federal and state agencies: National Oceanic and Atmospheric Administration (NOAA) Fisheries and NOAA Research, Oregon Department of Fish and Wildlife, U.S. Environmental Protection Agency, U.S. Fish and Wildlife Service, U.S. Geological Survey, and U.S. Department of Agriculture.

 

 

 

 

New Oregon Sea Grant publication probes the mysteries of hypoxia

Posted on by

Hypoxia: How Is It Affecting Ocean Life and Why?The causes and effects of hypoxia have been confounding marine scientists since the 1970s, when so-called “dead zones” first started appearing in oceans and large lakes. Currently there are more than 400 dead zones worldwide.

How did this happen, and how can it be fixed?

As Nathan Gilles, Oregon Sea Grant’s 2011 Science Communication Fellow, spent time with Sea Grant-funded researchers Francis Chan, Lorenzo Ciannelli, and Stephen Brandt, he uncovered a rich and complex story. That story is revealed in Oregon Sea Grant’s new publication, Hypoxia:How Is It Affecting Ocean Life, and Why?

The publication is available for purchase, and as a free download.

Science on Tap: Ocean science and good beer in Newport

Posted on by

Steller sea lionsNEWPORT – Oregon State University marine mammal researcher Markus Horning  steps to the bar for this month’s Science on Tap lecture, with The secret lives or seals: Using high-tech marvels to pry into ocean depths.

The talk, co-sponsored by the Hatfield Marine Science Center and Rogue Ale, starts at 6 pm  March 15 at Brewers on the Bay, on the South Beach waterfront south of the Yaquina Bay Bridge. Admission to the family-friendly event is free, and food and beverage will be available for purchase from the pub’s menu.

Horning, a pinniped ecologist with OSU’s Newport-based Marine Mammal Institute,   studies seals and sea lions in Oregon, Alaska and the Antarctic using telemetry – the science and technology of remote measurement via such devices as satellite-linked data recorders and tags.

The technology allows Horning and other scientists to monitor rarely observed aspects of marine mammal life in remote locations around Alaska and the Antarctic. Using advanced monitoring technology, researchers are able to follow the life – and death – of individual animals in the Bering Sea or under the Antarctic ice.

In recent research, the high-tech tools have helped show that more juvenile Steller sea lions are falling to predators than had been thought, casting doubt on prospects for the animals’ ability to recover from recent population decline in Alaskan waters.

OSU’s new research vessel arrives in Newport

Posted on by

R/V Oceanus: Almost homeNEWPORT – Greeted by welcoming blasts from the horns of NOAA research ships berthed nearby, the Research Vessel Oceanus steamed under the arch of Yaquina Bay Bridge in a rainy mist on Tuesday and into her new home port at Oregon State University’s Hatfield Marine Science Center.

It was the end of a 28-day voyage for the Oceanus, which sailed out of its former home at Woods Hole Oceanographic Institute on Jan. 25 and cruised down the East Coast and through the Panama Canal before heading northward for Oregon and her new home port.

Marine science fans on both coasts were able to follow the voyage via a Webcam affixed to the ship’s mast, which also beamed its geographic coordinates to a Google map set up for the occasion.

OSU acquired the Oceanus via the  University National Oceanographic Laboratory System, a consortium of 60 academic research institutions that operate 16 vessels around the country. OSU, a member of UNOLS, was retiring its venerable research vessel, The Wecoma, and looked to the consortium for a replacement. Although the two vessels are about the same age, a National Science Foundation rapid assessment determined that the Oceanus would be more cost-effective to operate for the next 5-10 years. By that time, OSU hopes to have a new ship.

The Oceanus was greeted by the same sounds that saw her off from Woods Hole: A chorus of horns from other research vessels, this time those docked at the new NOAA Marine Operations Center facility not far from the Hatfield Center docks.

A formal retirement ceremony for the Wecoma is being planned for March.

OPB highlights Sea Grant researcher

Posted on by

Oregon Sea Grant’s Guillermo Giannico and his study of the role flooded farmlands can play in fish survival are the subject of a new episode of Oregon Field Guide, broadcast on on Oregon Public Television this week.

Giannico, a fisheries ecologist with OSU’s Department of Fisheries & Wildlife who also serves as Sea Grant Extension fisheries specialist, was part of a team that set out a few years ago to learn whether dry-all-summer ditches that criss-cross Willamette Valley agricultural lands might house fish during the wet winter months.

What they found surprised them – and some of the farmers, too: A thriving winter habitat for several species of native fish.

Sea Grant research: learning-based tourism could spur major growth in travel industry

Posted on by

Children learn about octopuses at HMSC Visitor CenterNew research suggests that major growth in the travel, leisure and tourism industry in the coming century may be possible as more people begin to define recreation as a learning and educational opportunity — a way to explore new ideas and cultures, art, science and history.

But in a recent study published in the Annals of Tourism Research, John Falk, Oregon Sea Grant Professor of Free-Choice Learning, says that increasingly affluent and educated people around the world are ready to see travel in less conventional ways, and that lifelong learning and personal enrichment can compete favorably with sandy beaches or thrill rides.

“The idea of travel as a learning experience isn’t new, it’s been around a long time,” said John Falk, an international leader in the free-choice learning movement. Falk is among a group of Sea Grant professionals focusing their research on how people learn in their free time – through travel, in museums and aquariums, and through other experiences outside conventional classrooms.

At OSU’s Hatfield Marine Science Center in Newport, Dr. Shawn Rowe and colleagues are working under a $2.6 million National Science Foundation grant to create a Free-Choice Learning Laboratory, using high-tech tools to observe and analyze use of the Center’s public aquarium exhibits and what people take away from them.

Falk, meanwhile, holds one of two Free-Choice Learning professorships established by Sea Grant with the OSU Department of Science and Mathematics Education, which has developed a masters’ degree program in the emerging discipline.

Writing in the Annals of Tourism Research, Falk and his partners from the University of Queensland, Australia explore travel as part of a  “life-long and life-wide” learning experience, tracking the history of travel-for-learning back through the centuries, and examining how the experience has grown and changed in recent times.

“You’re already seeing many tour operators and travel agencies offer educational opportunities, things like whale watching, ecotourism,” Falk is quoted as saying in an article about the new research published today in Science Daily. “The National Park Service does a great job with its resources, teaching people about science, geology and history. The push for more international travel experiences as a part of formal education for students is an outgrowth of this concept.

“We’re convinced this is just the beginning of a major shift in how people want to spend their leisure time, and one that could have important implications for intellectual and cultural growth around the world.”

Documentary follows Sea Grant-supported research into salmon disease

Posted on by

Jerri Bartholomew with juvenile salmonKLAMATH FALLS – A new documentary, airing Feb. 7 on Southern Oregon Public Television, looks at the work of an Oregon Sea Grant-funded research effort to understand more about a lethal parasite that can infect wild salmon in the Klamath River and elsewhere in the Northwest.

Dr. Jerri Bartholomew, a microbiologist and director of Oregon State University’s salmon disease laboratory, has been studying Ceratomyxa shasta since she was an undergraduate. The parasite is a major cause of mortatlity in juvenile salmon, and may infect up to 80 percent of outmigrating juveniles in the Klamath River.  Bartholomew’s work – much of it funded by Sea Grant –  has led to new understanding of the parasite’s unusual life cycle, and how changes in water temperature and other environmental factors can cause it to proliferate.

The documentary, Saving Salmon, was scripted, directed and produced by Judith Jensen, director of Educational Solutions, a Klamath Falls nonprofit. Sea Grant videographer Steve Roberts contributed footage to the project, which is scheduled to air at 9 pm Feb. 7 on SOPTV.

Oregon floods: fish should fare better than people

Posted on by

Calapooia River flooding near Albany, Jan. 20, 2012Heavy rain and melting snowpack that flooded Western Oregon last week turned creeks and rivers into broad, brown torrents that might look like bad news for fish. But an Oregon Sea Grant fisheries specialist says his research suggests the opposite.

Guillermo Giannico, a research professor in Oregon State University’s Department of Fisheries and Wildlife, has conducted studies showing that fish – especially native species – can find refuge and food in flooded grass-seed fields.

Giannico’s research grew out of a project by fellow OSU researcher Stan Gregory to map the historic path of the Willamette River. The Willamette and its many tributaries once were more complex, braided streams. Multiple channels dispersed the impact of flooding, but dams, housing developments and forest transition have since funneled many rivers into single channels that run fast and furious during floods.

Giannico and others wondered how fish adapted to the change. Floods have happened for thousands of years, he said, and fish traditionally escaped high water in the main river stems by moving to off-channel habitat.

Turns out they still do. During seasonal floods, researchers took a look at ditches, low-lying farmland and other spots that are above water most of the year. To their surprise, they found 14 fish species — 11 of them native.

“That’s high diversity for this area, more than I would have bet we were going to get,” Giannico said.

Giannico noted a couple implications from the findings. Salmon, steelhead and other native fish, he said, are keenly tuned to changes in light and water temperature, and move to sheltering habitat — even if it turns out to be a flooded grass seed field. Invasive fish, often warm-water species, don’t get it. They’re unable to respond to the clues. As a result, native fish get a temporary break from predation and competition for food.

“Floods have always been a dynamic part of the system, much the same way that snow is for elk in Yellowstone,” said Giannico  “Over time, animals will adapt to get the most out of their habitat. We have found that native fish have adjusted their behavior to use these floodplains, mostly in agricultural lands, to great benefit.”

Sea Grant coastal erosion, climate work in Terra

Posted on by

High waves on the Oregon coastIncreasing winter storms since the 1980s have been sending higher, harder waves crashing into the Oregon coast, cutting away at seacliffs, roads and infrastructure in an area never known for its seismic stability. Scientists say the increased storm activity is consistent with predictions for the sorts of hazards the world’s coastlines will face as an effect of changing climate.

In Oregon, Sea Grant is partnering with communities and researchers to better understand the growing risks of coastal erosion, and to help counties and towns come up with plans for adapting to changes happening now, and predicted for the future.

In the latest issue of Terra, Oregon State University’s research magazine, Nick Houtman focuses on coastal hazard research and public engagement, highlighting the work Oregon Sea Grant is doing with Tillamook County and the town of Neskowin, where coastal hazards specialist Pat Corcoran has been working with a local group to develop the state’s first coastal hazards action plan.

Goodbye, Wecoma; hello, Oceanus

Posted on by

R/V WecomaNEWPORT – The Research Vessel Wecoma, which has been serving Oregon State University marine scientists for more than 35 years, is being retired from service and replaced with a somewhat smaller ship from the University National Oceanographic Laboratory System fleet.

The 184-foot Wecoma made her last cruise in November; her replacement, the Oceanus, is expected to dock in Newport in February, after making the long voyage from her former port at the Woods Hole National Oceanographic Institute on the East Coast, down through the Panama Canal and up the Pacific Coast to Oregon. A retirement celebration for the Wecoma will be held at the Hatfield Marine Science Center in Newport in March.

Both vessels are owned by the National Science Foundation, and operated by the University National Oceanographic Laboratory System, a consortium of 60 academic research institutions that operate 16 vessels around the country.

Mark Abbott, dean of the College of Earth, Ocean, and Atmospheric Sciences at OSU, had approached the National Science Foundation for  a rapid analysis of the two ships to see which one would be more cost-effective to operate over the next several years.  A team of technicians returned the verdict – a strong recommendation for the 177-foot Oceanus – after discovering some problems with corrosion and other issues with the Wecoma.

R/V Oceanus“There are a few differences in science capabilities,” Abbott said, “but Oceanus is very capable and will be more cost-effective to operate over the next five to 10 years, at which point we hope to have a new ship.’
