A nearly 30-foot deceased whale that washed up in Newport Beach this week disappeared overnight, likely carried back out to sea by strong surf.
The subadult humpback whale showed up on the shore at about 11th Street, between Balboa and Newport Piers on Wednesday, Feb. 18.
Authorities were figuring out whether to tow it back out to sea or chop it up and take it to a landfill to dispose of the carcass. Taking it back to sea had its challenges with a storm that showed up on Thursday, with strong swells and winds that would make it difficult for the salvage tow boat to get near the shoreline.
But Mother Nature took care of the job for them, the carcass gone by the time lifeguards arrived early morning Friday.
The Whale Response Team from Pacific Marine Mammal Center, alongside Newport Beach lifeguards and public works, dispatched before it was gone to take samples and measurements to gather “important life history data and biological samples,” said a release from PMMC.
The whale measured approximately 29.5 feet in length and is estimated to have weighed around 23,000 pounds, or 11 tons.
A subadult humpback is comparable to a teenager in human years, PMMC said.
“Humpback whales are a sentinel species,” said Dr. Alissa Deming, veterinarian and vice president of Conservation Medicine and Science at PMMC. “Every stranding represents both a loss and an opportunity — a unique chance to better understand the threats these animals face and how we can protect the population as a whole.”
Thursday evening, the PMMC and OARRA’s necropsy teams collected additional samples, including skin, blubber, baleen, and bodily fluids for laboratory analysis, also confirming the whale was a female.
PMMC also deployed a thermography drone to document the whale and assess for visible injuries.
However, a rough surf and a rising tide made it unsafe to conduct a full necropsy at that time, the release said.
“While marine mammal strandings are always difficult to witness, they offer rare and valuable opportunities for scientific investigation. A thorough examination can help determine the cause of death and provide insight into the overall health of whale populations along the Southern California coast,” the PMMC announcement said. “The region has experienced an increase in whale strandings in recent years, coinciding with intensified human activity and changing ocean conditions.”
OARRA had also planned to attach a satellite tag to the whale, allowing researchers to track its movement offshore and gather additional data on post-stranding drift patterns and ocean currents.
“This is a powerful example of what collaboration within the ocean community can accomplish. The samples and documentation collected will provide greater insight into this whale’s untimely death and contribute valuable scientific data to ongoing regional research,” Keith A. Matassa, CEO of OARRA, said.
