Return to the Davidson Seamount Whale Fall | Nautilus Live

In October 2020, E/V Nautilus returned to the Davidson Seamount whale fall in Monterey Bay National Marine Sanctuary to find a dramatically different scene from the one discovered just the year before.
During the final dive of the 2019 Nautilus expedition season, our team discovered the skeletal remains of the baleen whale lying on its back.
“It is so different,” noted scientists aboard the vessel.
A whale fall occurs when a deceased whale descends to the seafloor, bringing with it a banquet of vital nutrients to deep-sea scavengers. A side-by-side comparison of the 2020 visual survey taken by ROV Hercules in 2019, showed that the whale fall had undergone dramatic density changes in the 12 months since our last visit. Whereas the whale fall was once covered in a thriving abundance of life in October 2019, it was nearly devoid of organisms just a year later.
“The rib bones are just kind of disintegrated there,” said Lead Scientist Chad King. “The whole rib cage was supported last year. I mean, it was still upright and everything.”
We sampled large pieces of bone in order to further characterize the whale and the process of decomposition that it underwent, and then we “waved goodbye” — until next year.

"Lead Scientist Chad King" Best name of the history of names
-
Watched this live last year. What a change. Thank you for going back.
-
So so glad they did the side by side comparisons so I didn't have to pull up the old video and flip back and forth. Little stuff like that makes a huge difference for the community (:
-
The clear enthusiasm in the scientists' voices is absolutely fantastic - so much passion for their work.
-
It's great that our current technology allows us to see video like this and the live reactions of those there too. It's informative and interesting!
-
if they'd told me this was a job when i was in school....

2000: watching grass grow 2020: watching a whale decay ????: watching stable iron decay

2:48 Yellow rope waves bye whale

I watched this live. It was amazing that you could find such a small target in such a vast ocean! Well done Nautilus!
-
It’s nice to see more nautilus groups. I am a student of Dr. Gregory Barord, who helps “save the nautilus” and this is amazing as it helps give people insight into what nautilus do and give more information about them.

Some Hilarious Intern in the background at 2:00 , ''Geronimo!!''

Stuff like this should be put into a repository of videos for different jobs to show to schoolkids. I keep discovering stuff like this across a huge range of employments and wish I'd started down those paths as a kid.

"Humerus, not in the "it makes you laugh" kind of humerous" "That's the ulna, that's the funny bone" claw grabs piece WOOOOOOWWWWW!!!
-
It’s crazy you went back and it’s actually still there
-
I randomly tuned into the broadcast last year just before they found it and watched it live, thank you for coming back
-
I love this channel so much. The scientists in each video make you feel part of the journey and bring the wonderful world of exploration right into our homes with amazing footage to boot. I always laugh when something cool happens on screen and I end up saying “woah!” at the same time as the team. There’s only good vibes to be found here - Thank you for sharing your world with us! :)
-
This is the first youtube channel I have come across of actual scientists doing science/ making discoveries live.
-
I missed the live dive but glad you posted it. Been watching the live stream since early Sept almost every day. LOVE IT!

Imagine joining a Discord call and seeing 4 people talking about a decomposing Seamount Whale
