Heceta Bank - Oregon's Hidden Wonder

Add some more info about this item...

Hidden below the surface, 35 miles offshore from Cape Perpetua, there is a submerged feature that has a huge impact on Oregon's coastal habitats. This is the story of one of the least known but most important natural features on the West Coast.

'All our crabs were dead': Oregon's hypoxia hazard

October 29, 2018

Hypoxia is a seasonal occurrence along the West Coast where areas of ocean surface water have little to no oxygen, creating an environment where fish and crustaceans cannot survive.

Due to changing ocean waters caused by climate change, hypoxia has the potential to crash Oregon’s crab and halibut fishing industries.

The Changing Sea

March 21, 2010

"In our final episode ... we discover that the ocean is sending us clear signals. Off the rugged and beautiful coast of British Columbia we meet scientists and fishermen who are shocked at the recent arrival of a voracious new creature ? the Humboldt squid. This monster-sized squid native to the equatorial waters of Mexico has moved north and ushered in a cascade of changes to the ecosystem. Their arrival is part of a disturbing pattern that is emerging with species movement being tracked around the world ... we illustrate how the ocean's chemistry and systems are being compromised by increased acidity, less oxygen and warming temperatures ... In the idyllic waters of the Bay of Naples, we get a glimpse of our future ocean, thanks to the mythic Mount Vesuvius. As scientists swim through lush green seagrass beds, they collect creatures whose shells are dissolving, and we discover that this amazing place has a terrible secret. It has been naturally acidified for millennia ? could this be our ocean's future?"-- One Ocean series website.

Dead Zone Update

March 18, 2010

"A one time dead zone off Oregon’s coast turns out not to be an isolated incident. Oxygen levels are plummeting every summer now. Scientists deploy an army of sensors, including a diving robot explorer, to learn what’s changed in our ocean." -OPB

Hypoxia: Dead Zone


"How did the dead zones in the ocean off Oregon form? Join scientists Jack Barth and Francis Chan of Oregon State University as they conduct hypoxia research along Oregons coast. Produced by Green Fire for the Partnership for Interdisciplinary Studies for Coastal Oceans." -piscoweb

Broader Coastal and Ocean Efects


"What do "dead zones" have to do with climate change? How might increased levels of carbon dioxide affect sea life? How will storms and flooding affect the landscape in the coming years?" -Oregon Sea Grant

Community Organization, Ocean Style: Ocean Observatories Initiative

October 27, 2009

"We’ve talked to numerous scientists on Ocean Gazing about their shared dream of piping data from the ocean onto the web and into the palm of your hand in real time, 24 hours a day. That dream has a name: the Ocean Observatories Initiative." -Ari Daniel, COSEE NOW

Dead Zones: Dr Kiki's Science Hour

October 21, 2009

"Dead Zones: another ecological scourge that may earn a place on the ever-lengthening list of problems associated with climate change: the formation of some types of so-called "dead zones"--marine expanses covering hundreds, or even thousands, of square miles that become too oxygen-starved during the summer to support most life forms." -This Week in Technology Wiki

Dead Zones: Webcast

October 8, 2009

"Yet another ecological scourge may earn a place on the ever-lengthening list of problems associated with climate change: the formation of some types of so-called "dead zones"—marine expanses covering hundreds, or even thousands, of square miles that become too oxygen-starved during the summer to support most life forms.

In a webcast that features a Q&A with reporters, Jack Barth of Oregon State University explains how climate change may be promoting the development of Oregon's dead zones, summarizes the ecological impacts of dead zones, discusses why scientists believe that dead zones are now regular summer fixtures in Oregon's coastal waters, and describes his research team's pioneering methods for studying dead zones in Oregon and Chile. 

The results of Barth’s analyses of the Pacific Northwest’s dead zones are particularly surprising because most of the Earth’s 400+ dead zones are caused by pollution dumped into coastal areas by rivers." - National Science Foundation (US)

Ocean Circulation


"It took decades to develop systems that help us predict the weather in the atmosphere. Now scientists want to be able to do the same within the ocean, helping us better forecast the weather, develop pollution and erosion controls and aid in search and rescue. Oregon State scientists have exciting new tools which are allowing them to track the complexities of ocean circulation using robot submarines, navigational satellites and computers." -OPB
