Dawn Noren

Dawn Noren is a federal research biologist with NOAA. She studies the physiology of the Southern Resident killer whales, specifically focused on blubber and body condition. She has worked on several high profile cases, including the historic intervention staged to save the young ailing J50, who eventually disappeared and is presumed dead. Recovery conversations have mostly focused on food, as the Southern Resident orcas only eat fish and their preferred diet, Chinook salmon, are also declining. While Noren does not disagree with the need to recovery salmon runs, her research shows that the whales are likely facing a much more complicated battle to survive. At the time of this recording, there are just 73 Southern resident killer whales left alive in the wild.

Dawn Noren: "What's Killing Killer Whales?"

Snohomish County and the Tulalip Tribes survey fish four times a month around the Snohomish River estuary by setting a net and counting the fish it catches. They measure size, record species, and look to see if Chinook salmon are recovering in light of habitat restoration projects. Chinook salmon are the preferred food of the Southern Resident killer whales, the 76 orcas on the brink of extinction. Since the fish aren't doing well, the whales are starving. Scientists have focused much of their effort on restoring salmon habitat which has been lost to development, agriculture and other issues, but they say the projects are way behind and need to speed up if we want the orcas and their favorite prey to survive.

Linda Rhodes

Linda Rhodes is a microbiologist with NOAA's National Marine Fisheries Science Center who studies how parasites in human sewage and animal waste may be hurting the Southern Resident killer whales. The amount of human sewage that ends up in the Salish Sea will shock you. It creates parasites that can enter the whales through their blow holes when they come up for air. Remnants of sewage have also been detected deep within the water column. It's possible these microbes could be causing the orcas to feel sick enough they don't want to eat, which may contribute to their health risks. Often experts point to a lack of food for the whales, who prefer Chinook salmon, which are also dwindling in number. But what if in addition to a lack of food, the Southern Residents just aren't hungry because they're sick?

Tim Ragen

Tim Ragen spent 15 years as a research biologist for NOAA, coordinated stellar sea lion recovery efforts, and then worked for 13 years with the U.S. Marine Mammal Commission. He has invaluable insight into what it takes to recover a species on the brink of extinction like the Southern Resident killer whales. Interestingly, Ragen supports a cull of seals and sea lions as a drastic measure to save decreasing Chinook salmon stocks, the preferred prey of the Southern Resident orcas, who do not eat marine mammals or sharks like other killer whales. Ragen asks all of us, what kind of world do we want to live in and are we doing all we can to protect that future?

KURT RUSSO

For thousands of years, the Lummi Nation has been performing ceremonial feedings for killer whales, and continue that tradition today with the Southern Resident killer whales, who are now facing the real possibility of extinction.  The Lummi believe the orcas are their ancestors. They recently assisted in a historic intervention to save the ailing calf, J50, who eventually died. Kurt Russo is with the Lummi Nation's Sovereignty and Treaty Protection office.

Brad Hanson

Brad Hanson is a wildlife biologist with NOAA's Northwest Fisheries Science Center and one of the scientists most intimately acquainted with the decline of the Southern Resident Killer Whales (SRKW). After 15 years of studying them using satellite tags among other techniques, Hanson believes the SRKW are likely dying from disease not starvation, as has been widely publicized. He says they're likely more susceptible to pathogens because they don't have enough food to eat. The SRKW are not like other orcas who eat mammals and sharks. They only eat fish and they prefer Chinook salmon. Unfortunately, those fish are also disappearing. At the time of this recording, there are 75 SRKW left alive in the wild.

Greg Ruggerone

Greg Ruggerone and his team recently published research they believe shows a connection between pink salmon and the decline of Southern Resident killer whales. The endangered orcas primarily eat Chinook salmon and Ruggerone believes pink salmon are somehow interfering with the whales' ability to forage.

Greg Ruggerone: "The Pink Problem"

Josh McInnes studies transient killer whales, a group of orcas that has rebounded from dwindling numbers. They differ from the fish-eating Southern Resident killer whales because they eat marine mammals. McInnes discusses reasons for their comeback and why he still has hope for the Southern Residents.

Holly Fearnbach

Dr. Holly Fearnbach with SR3 (Sealife Response, Rehabilitation &amp; Research) uses aerial photogrammetry to document the health trends of the Southern Resident killer whales. Her photos recently diagnoses another orca, K25, as declining in condition. They have also shown at least three new pregnancies, one in each of the J, K and L Pods.

Sam Wasser

Sam Wasser is the Director of the Center for Conservation Biology at the University of Washington. He is a poop expert. His studies of Southern Resident killer whale scat has given scientists unprecedented knowledge of their health, such as how stress hormones affect miscarriages. He's using the same focus on poop to help curb the illegal trafficking of ivory.

Sam Wasser: "Poop & Poaching"

Joe Gaydos

Dr. Joe Gaydos is a veterinarian and scientist with SeaDoc Society. He worked closely on an intervention to save J50, the sickly and starving young Southern Resident killer whale who recently died. Dr. Gaydos is currently compiling a health database for the Southern Resident orcas in order to inform both policy surrounding the whales as well as any future efforts focused on individual survival. Dr. Gaydos also sits on Governor Inslee's Southern Resident Killer Whale Recovery Task Force.

Kevin Ranker

Sen. Kevin Ranker (D-Orcas Island) sits on the task force created by Governor Inslee to save the Southern Resident killer whales from extinction. He says the whales have faced the same challenges for decades while those in charge did nothing, but he's more hopeful these days thanks to public outcry. He says "extinction is not an option."

Sen. Kevin Ranker: "Extinction Is Not An Option"

Ken Balcomb

Ken Balcomb has been identifying and studying the Southern Resident killer whales for decades with the Center for Whale Research. After J50's death, he says it's past time that action takes the place of politics. The orcas are down to just 75 with very few reproducing. He hopes he does not see the end of them in his lifetime, but believes it's a real possibility.

Ken Balcomb: "Witnessing Extinction"

Bob McLaughlin

The last orca calf to be live captured in Puget Sound in a rescue effort to save her life was Springer, an orphan who liked to swim near boats. She was captured and returned to her family group. The same equipment used in that intervention will be used if officials capture the ailing J50 for rehabilitation. Also called "Scarlet", the near-death Southern Resident orca calf continues to decline despite efforts to dart her with antibiotics. If captured, the plan is to diagnose and treat her with the hope of returning her to the JPod.

Thank you for the podcasts. Monterey Bay whale lover/photographer and Happy Whale contributor. I love learning as much as possible about any ocean life and what we can do to help keep the ocean healthy for all its creatures. Keep up the great work. Prayers for the pod

Great education!

Love what you’re bringing to the table to discuss on. As a Killer Whale lover, all tour podcasts have served as a great hub for old and current news regarding the SRKW’s. I would just like to hear better quality. Why don’t you record the conversations had over FaceTime audio or an app to make the conversation easier to hear? Thank you for all that you do!

Great content but quality of voice needs improved
