Cover of the 2019-20 Oregon Coast Quests Book

Oregon Coast Quests are suitable for individuals, families and groups of all ages who wish to explore parks, trails and other outdoor spaces at their own pace.

The 2019-20 edition of Oregon Sea Grant’s popular “Oregon Coast Quests Book” is now available, featuring 28 of the clue-directed hunts in English and one in Spanish. Most of the Quests are in Clatsop, Tillamook, Lincoln, Lane, Coos, and Curry counties; three are in Benton County.

Eight of the Quests are new, and the directions for many of the previous Quests have been updated to reflect changes in site terrain, landmarks, signage and other details.

Cait Goodwin, an educator with Oregon Sea Grant and the coordinator of its Quests program, described Quests as 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. They’re 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.

The price for the 252-page book is just $10, with funds going to support Oregon Sea Grant’s Oregon Coast Quests program. You can buy copies online here, or from the retailers listed here.

Researchers at Oregon State University have launched a 3.5-year project funded by Oregon Sea Grant that aims to help coastal towns become more resilient to storms, earthquakes, tsunamis and a rising sea. Oregon Sea Grant is providing nearly $900,000 in funding.

Launched in July, the project is led by Peter Ruggiero, a coastal geomorphologist in OSU’s College of Earth, Ocean, and Atmospheric Sciences.

It aims to:

  • use a computer model to simulate how climate change, earthquakes, tsunamis, population growth, land use, and hypothetical policy scenarios might affect communities’ abilities to weather coastal hazards;
  • help policymakers understand the impacts of their decisions;
  • result in a better understanding of options, costs and benefits for adapting to coastal hazards; and
  • develop an interactive Web portal that will provide decision-makers and the public with information on how to increase coastal resilience.
Researchers will look at how land use impacts towns’ abilities to weather coastal hazards.

Other faculty on the project are:

  • John Bolte, an expert in computer simulations in OSU’s College of Agricultural Sciences;
  • Dan Cox, an engineer in OSU’s College of Engineering;
  • Steven Dundas, an economist in OSU’s College of Agricultural Sciences;
  • Jenna Tilt, a land-use planning specialist in OSU’s College of Earth, Ocean, and Atmospheric Sciences; and
  • Pat Corcoran, a coastal hazards specialist with Oregon Sea Grant and the OSU Extension Service.

The project will conclude in 2022.

New video: ‘Tsunami Quests’ help coastal residents and visitors prepare for major earthquake and tsunami

Posted on by

Scientists say there is a 30 percent chance of a massive earthquake and tsunami striking the Pacific Northwest in the next 50 years. One way coastal residents and visitors can prepare for such a disaster is to learn evacuation routes.

A new video from Oregon Sea Grant, “Tsunami Quests,” reveals how the program is helping coastal residents and visitors prepare. One way it does this is by teaching people how to create and use self-guided evacuation routes modeled after a treasure hunt.

In these hunts, which are called Quests, walkers follow a map and a series of educational clues about their surroundings to reach higher ground. At the end, they find a hidden box that contains a guest book and rubber stamp to mark their accomplishment. The aim is that by exploring these routes for fun in their free time, residents and visitors will later know where to flee in the event of a tsunami.

Background

In February 2016, Oregon Sea Grant (OSG) organized a series of workshops at the Hatfield Marine Science Center (HMSC) in Newport, Oregon, to bring educators, state parks personnel, researchers and emergency management experts together to discuss how communities can prepare for tsunamis. Participants also learned how to help students create a tsunami Quest.

In the spring of 2016, workshop attendees imparted their knowledge to 120 Newport seventh-graders at HMSC. The students listened to presentations from engineers and geologists, studied tsunami inundation maps and interpretive signs, calculated how fast they would need to walk to escape, and learned about soil liquefaction. They also walked an evacuation route that starts at the OSG-operated Visitor Center at HMSC, which is expected to be flooded during a tsunami, and ends about a mile away, atop Safe Haven Hill. The students created a Tsunami Quest for that route and tested the activity on community members and two classes of fifth-graders in Newport. Their Quest is online (“HMSC Tsunami Quest,” http://bit.ly/2s0O1YI). To date, nearly 300 people have walked the HMSC Tsunami Quest.

Partners

Partners in the Tsunami Quests effort include the Lincoln County School District, Oregon State University, Oregon Parks and Recreation, Hatfield Marine Science Center, the Gray Family Foundation, and the OSUEA Hoecker Award.

Five years after Japanese tsunami, concern over invasives still exists

Sam Chan tells visitors to the washed-up Japanese dock about invasive species that may have hitched a ride

Oregon State University Natural Resources Leadership Academy (NRLA) Agate Beach, tsunami debris field trip, June 21, 2012.

Five years after a massive earthquake struck Japan and triggered a tsunami that is still washing debris onto the West Coast of the United States, scientists are unsure whether any of the 200-plus non-native species that hitchhiked over on that debris have gained a foothold in Northwest waters.

Four separate findings of barred knifejaws (Oplegnathus fasciatus) – a fish native to Japan – have been reported over the past three years, and Mediterranean blue mussels have been ubiquitous on tsunami debris. Yet no populations of non-native species that arrived with the tsunami debris are known to have established reproductive populations.

“Maybe we dodged the bullet, although it is still too early to tell,” said John Chapman, an Oregon State University invasive species expert who has investigated tsunami debris along the Pacific coastline. “It is possible that we have not yet discovered these reproductive populations, or that some species from Japan may be cross-breeding with our own species.”

Scientists have not had adequate resources to look extensively up and down the Pacific coast for evidence of establishment by non-native species – especially along long stretches of rugged shoreline.

The magnitude-9 earthquake that struck Japan on March 11, 2011, was the largest in that country’s history and generated a tsunami that had waves estimated as high as 133 feet. The power of these two events, combined with the growth of human settlement over the past two to three centuries, created a new paradigm, said Samuel Chan, Oregon Sea Grant’s expert in aquatic ecosystem health and invasive species.

“A tsunami 300 years ago, or even just 60 years ago, would not have created as much marine debris that became a vehicle for moving species across the Pacific Ocean that could become invasive,” Chan said. “What makes these major tsunami-driven events different in modern times is the substantial human industrial infrastructure that we have built along the Pacific coast.”

OPB’s “Unprepared:” Are we ready for the Big One?

Posted on by

“Unprepared,” a special edition of Oregon Public Broadcasting’s Oregon Field Guide series airing Oct 1, examines whether Oregonians are ready for the magnitude 8 or stronger earthquake scientists are predicting for the offshore Cascadia Subduction Zone within the next .

The program looks at what it takes to get ready for a disaster of that scope – and the potential consequences if we don’t.

Oregon Sea Grant’s coastal hazards specialist, Patrick Corcoran, is among the experts who contributed to the program. Corcoran is accustomed to talking people through preparedness, from how families can create a “Quake Kit” of supplies that can be grabbed at the first sign of earthquake to how entire coastal communities can – and should – relocate critical facilities such as hospitals and schools from the likely path of the devastating tsunami that likely would accompany such a quake.

“Unprepared” is part of a year-long initiative by OPB and Oregon Field Guide to inform people about the dangers of a megaquake, and to examine ways that our region can be better prepared for such a disaster. Visit the OPB Website for more information.

Cascadia earthquake: Finding the sweet spot between fear and action

Posted on by

A recent national news article suggesting that everything in Oregon west of Interstate-5 “would be toast” in a major Cascadia Subduction Zone earthquake certainly drew attention to the seismic reality facing the Pacific Northwest.

The concern, though, is that people are focusing on the most draconian or extreme scenarios, experts say, which can lead to a sense of fatalism. The reaction illustrates the state of earthquake and tsunami preparedness – or lack thereof – in the United States, said Patrick Corcoran, Oregon Sea Grant’s Astoria-based coastal hazards specialist, who works with coastal communities on disaster preparedness.

It’s a matter of feast or famine.

“The Cascadia Subduction Zone has shifted from a science project to a social studies project,” Corcoran said. “We need to find a sweet spot between fear and action. What I try to do is temper the tendency of people to toggle between the poles of ‘it won’t happen here’ and ‘it will be so bad that there’s no use worrying about it.’”

Japanese fish found off Oregon; 2011 tsunami link possible

Striped Knifefish

The striped knifejaw caught off Port Orford in veterinary quarantine tank at HMSC

NEWPORT – Oregon scientists, including specialists from Oregon Sea Grant, are examining an unusual fish hauled out of the ocean near Port Orford in a crab pot last week for possible connections to the 2011 Japanese tsunami.

The fish, an Oplegnathus fasciatus (sometimes called a barred knifejaw or striped beakfish) is in quarantine at OSU’s Hatfield Marine Science Center, under the care of OSG aquatic veterinarian Tim Miller-Morgan.

While it’s hard to say whether the fish was transported across the Pacific by debris from the 2011 Tōhoku earthquake and tsunami that struck Japan, its appearance in US waters raises questions, according to OSU’s John Chapman, an aquatic invasive species specialist based at the Hatfield Center.

Sea Grant invasive species expert Sam Chan estimates the fish to be around 1-2 years old, which makes it unlikely the animal left Japan in 2011. But, he added, “a boat could have been milling around Asian waters for the past 2-3 years and then picked up the fish and ridden the currents over. The big question is – are there more of these.” He said Sea Grant would work with Oregon commercial fisherman, crabbers and others to keep a lookout for more of the species.
