At the intersection of science and art, you’ll find Jerri Bartholomew, a microbiologist and salmon researcher who also has a passion for working with glass.
“I see my artwork as being parallel to my scientific experimentation,” she says. “Science is often a very long process–it may take months, years, or even decades to find an answer to something, whereas art… you can get into the studio and experiment and come out with a product within hours, days, or weeks.”
But whatever the time scale, Bartholomew’s passion for scientific processes is evident as she shares her successes in solving some of the mysteries behind a growing threat to Pacific salmon, a parasite called Ceratomyxa shasta. Like many other parasites, C. shasta has a complex life cycle, requiring both vertebrate and invertebrate hosts to successfully reproduce.
In this installment of Netcasts, we visit the John L. Fryer Salmon Disease Laboratory, where Bartholomew and her team are using genetic tools to piece together a puzzle, searching for the right ways to target parasites while protecting salmon. We’ll also get a glimpse at some of her artwork, including some more recent pieces in a set called “Pages From a Naturalist Notebook.”
In this episode of Netcasts, we travel to Astoria to visit Pat Corcoran, coastal hazards specialist for Oregon Sea Grant Extension. Corcoran works with coastal community members and researchers around the world to prepare coastal residents for natural hazards, such as erosion and tsunamis. Corcoran talks about his experiences bringing the findings of research conducted by OSU’s Peter Ruggiero to the community of Neskowin, where residents are exploring strategies to mitigate shoreline retreat. Corcoran also shares some photographs and wisdom from his recent visit to Japan, where he was able to view the aftermath of the March 2011 tsunami. Stay tuned to Sea Grant’s YouTube channel for more Netcasts.
Who are Sea Grant’s Extension agents and researchers? What do they do, exactly? What are some current research topics? Netcasts, a new YouTube video series from Oregon Sea Grant, goes behind the scenes to find out the answers to these and other questions. The first installment features Mark Whitham, a seafood product developer for Oregon Sea Grant Extension, who takes us to the Skipanon micro cannery in Warrenton, Oregon. Be sure to watch for more Sea Grant Netcasts on YouTube.
Grab your hiking boots and binoculars! This video will take you on a scenic and historical walk through the beautiful prairie headlands, forests, and grassy marshes of Cascade Head and the adjoining Salmon River estuary.
Ever heard of Pixieland? Kami Ellingson, from the Siuslaw National Forest, will take us on a guided tour of the complex history of commercial and residential developments that once threatened to pave paradise.
Stay on the trails, because that little blue violet up on the headlands feeds the Oregon silverspot caterpillar, one of four threatened or endangered animal species that live here. The Nature Conservancy’s Debbie Pickering tells us the butterfly’s story.
Back in the marshes, NOAA Fisheries scientist Dan Bottom describes the history of a massive habitat-restoration project, in which dikes were removed from the estuary in the hope of improving salmon runs. Western Oregon University Professor Karen Haberman shares her Sea-Grant sponsored research in the marsh–an unusual focus area with surprising consequences.
And finally, Eric Vines gives us a tour of the Sitka Center for Art and Ecology, one of the many recreational opportunities at Cascade Head.

Tsunami alerts were triggered up and down the Oregon Coast this morning, following a deadly 8.9 magnitude earthquake in Japan. Reverse 911 calls and emergency sirens alerted Oregon coastal residents to potentially dangerous tsunami waves created by the distant quake, and the National Weather Service has issued a tsunami advisory. Oregon Sea Grant features a short film on tsunami preparedness: “Reaching Higher Ground: The 3 Things You Need to Know” (3:09).
To learn more about what causes a tsunami, check out our longer film, “Reaching Higher Ground” (14:02).
A new video is available documenting part of the public dissection of a 12-foot great white shark that was featured in an earlier blog post. The shark died after becoming entangled in the ropes of a crab pot, but the shark’s death may mean educational benefits to scientists.
William Hanshumaker, a marine science educator at the Hatfield Marine Science Center, explains: “There are researchers from throughout the country who are interested in what we’re doing here and have requested sample materials…. This is also an opportunity for the public to observe first-hand this unique creature and how scientists conduct research and share information.”
The 2-minute video is a time-lapse sequence showing the fin removal portion of the necropsy.
Dan Cox is the director for the O.H. Hinsdale Wave Research Lab at Oregon State University. This bonus footage was recorded for the film Reaching Higher Ground: Oregon Sea Grant’s Tsunami Research and Community Engagement, which has been released to DVD and is available to view for free online. In this short video clip (which does not appear in the film), Cox explains why the city of Seaside was chosen for developing a 1:50 scale model to flood repeatedly with scale-size tsunami waves. You can learn more about the project here.

In this preview to an upcoming documentary featuring Climate Change in Oregon, Michael Harte (Oregon State University’s College of Oceanic and Atmospheric Sciences, or COAS) explains that the effects of global climate change on our day-to-day lives are not necessarily the effects talked about in the larger discussion of climate change.
The documentary, scheduled for release this summer, will feature interviews with researchers that are already identifying effects on Oregon’s coast linked to climate change. Part of the film will include recent research findings by Jack Barth (COAS) who discusses how local salmon are affected by changes in ocean conditions. Sea Grant Extension agent, Robert Emmanuel, will describe recent increases in flooding in Tillamook, and Nathan Mantua, from the University of Washington, will talk about the effects of increasing winter storm activity.

In the Hinsdale Wave Research Lab at Oregon State University, Associate Professor Tuba Ozkan-Haller studies how beaches recover after winter storms. The hope is that this information will go into predictive models that can help developers make smart decisions about how to protect properties or infrastructure along coastlines. “People who have lived near the coast know that in the summertime the dry beach actually increases,” says Ozkan-Haller. “There’s more sand that is just sitting on the dry beach area in the summertime. And that sand actually goes away in the wintertime because of the storms and forms a bar, sort of a submerged island offshore. It’s the way that the beach protects itself…. as the summer then approaches again during springtime, waves move that bar, that mound, back onto the beach. And, we found out that we’re actually very bad at predicting how that happens.”
She is joined by civil engineering professor Merrick Haller, who describes how the instrumentation is used to interpret the data. After the data is analyzed, they hope to build numerical models that will help predict what will happen to the beaches after severe storms, and whether there will be increased need for protective structures or beach nourishment.
