Gray Whale Carcass Washes Ashore in Gearhart, Oregon: A Growing Strandings Trend

Gearhart Stranding
On the Oregon coast near Gearhart, a 41-foot male gray whale washed ashore last week after being dead for months, Seaside Aquarium general manager Keith Chandler said. The carcass was too decomposed for a necropsy.
Recent Strandings on Oregon and Washington Coasts
Seaside Aquarium reports 19 gray whale strandings on Oregon beaches in 2024. The Cascadia Research Collective records at least 30 strandings along Washington’s coastline this year. More than half of the deaths show signs of malnutrition, though necropsies were omitted for roughly a dozen Washington cases.
Background: Seasonal Winds and Recent Strandings
Strong westerly winds this year have accelerated the drift of marine debris and carcasses onto shorelines, contributing to the recent spike in strandings.
Environmental Context: Warming Waters and Food-Chain Stress
Chandler attributes the strandings to climate-driven warming of coastal waters, which thins plankton and reduces its nutrient content. Gray whales rely on plankton as their main food, and poorer plankton quality can lead to emaciation. Warmer water reduces plankton nutrient density, further lowering food quality for whales.
Official Observations and Stakeholder Responses
Seaside Aquarium officials note that strong westerly winds this year have increased the number of marine carcasses reaching shore. The Portland State University team conducts necropsies on fresher whales, while the West Coast Marine Mammal Stranding Network provides a 1-866-767-6114 hotline for public reports. The Cascadia Research Collective tracks ongoing strandings across the region.
Data Gaps and Unresolved Causes
Necropsies were not performed on about a dozen Washington strandings, leaving cause of death uncertain. The Gearhart whale’s advanced decay also prevents tissue analysis, so its specific mortality factors remain unverified.
Implications for Marine Ecosystems and Coastal Communities
The rise in gray whale strandings suggests stress in the coastal marine ecosystem, potentially affecting other species that share the same plankton base. Local towns face increased beach-clean-up workloads, and scientists lose data when carcasses decompose beyond scientific use. The observed decline in food quality may affect other marine species dependent on the same plankton.
Verbatim Quotes
- “The food sources have been compromised. The warmer water means the nutrients that they're getting aren't as good, so the whole food chain is kind of not as healthy,” — Keith Chandler, General Manager, Seaside Aquarium
- “The fresher ones, the team from Portland State [University] will come down and they'll go in and do measurements, take samples and stuff, measurements of the internal organs. But on one this decayed, you won't gain anything from it scientifically. And it's just kind of a mess to do when they're this rotten,” — Keith Chandler, General Manager, Seaside Aquarium
Future Monitoring and Reporting
Portland State University will prioritize necropsies on less-decomposed strandings. Authorities continue to urge the public to call the West Coast Marine Mammal Stranding Network hotline to improve reporting and response.
