L112 Stranding Report Released
On May 15 the Northwest Regional Office of NOAA's National Marine Fisheries Service released "Progress Report 2" in the investigation of the stranding of Southern Resident Killer Whale L112 this past February.
Earthfix's Ashley Ahearn interviewed Joe Gaydos for a story on the investigation. The story, titled "Report Inconclusive on What Killed Orca L112" quotes Joe acknowledging that it's challenging for everyone that they can't yet pinpoint a cause of death.
The Progress Report from NOAA describes in detail what has been done so far in the investigation and what's left to do. Worth a read: http://www.nwr.noaa.gov/Marine-Mammals/Whales-Dolphins-Porpoise/Killer-Whales/L112-rpt2.cfm.
The preliminary conclusion is that there's evidence of physical trauma of sufficient force to kill the animal, but it's not clear what that trauma was.
Photos of the necropsy (referred to in the report as the Gross Examination) are here. Viewer discretion advised.
Joe Gaydos was also featured in an NPR story on the whale's death.
