Nainoa Thompson delivers the lone, incredible keynote at the Ocean Exploration Forum.

The Rebirth of Polynesian Voyaging.

Things I learned today: autonomous drone ships are still required to have a paddle.

I'm at MIT today and tomorrow talking deep-sea mining policy. One of the important lessons that always strikes me during my talks with representatives from extractive ocean industries is that everyone really is genuine. People care about environmental impacts. Even miners. Even wildcats.

Yet that stewardship ethic doesn't always grow with the scale of industry.

US followers--tomorrow is Election Day! Do you know where your polling place is? How you're getting there?


I still have to travel way too much for work, but this year my goal was to at least never fly anywhere for just one thing.

So far I've managed to stack major projects so that if I have to hop a plane, we get a lot more than one trip worth of value out of it.

Heading to Boston now to Interview sources, participate in a mining policy working group, and present at the OER All Hands on Deck ocean conference. Oh, and a high school reunion.

I might also sleep.

I'm standing in a line right now. I'm wearing jeans. The person ahead of me is wearing jeans. The person behind me is wearing jeans. Without being too creepy, a quick survey says the line waiting to board this plane is at well above 50% blue jeans.

The one fact that just keeps blowing my mind: at any given moment, nearly half of all people in the world are wearing blue jeans.

Which are now also among the most energy-intensive mass-produced textiles.

FYI, I'm now running the Deep-sea Mining Observer. The only trade journal dedicated to tracking the progress of the deep-sea mining industry.

Pretty excited to get back into feeding habits analysis looking at the diet of juvenile Bull Sharks from Pamlico Sound, North Carolina. As you can probably tell, it can be tough to identify some of the more-digested prey items, so we're saving samples for genetic ID.

Gut contents we found from juvenile Bull Shark stomachs today included this large, partially-digested fish. Can't wait for the genetic barcode results to tell what this beast was before it became shark food.

Juvenile Bull Sharks seem to appreciate Pamlico Sound Blue Crabs just as much as I do.

Surprisingly, we found evidence that at least one of the juvenile Bull Sharks we sampled stomach contents from had encountered a human before. Most of a fishing rig was in its stomach. It looks like the fisherman may have tried to cut the hook, which makes me wonder how the rest of the rig ended up in there.

Though partially-digested, there are few tells for identifying this as more than likely an Atlantic Menhaden. These include the strip of "dark meat" down the middle, the patch of silvery skin, and that big dark gizzard that seems to be the last part of this fish to be digested. Everything likes to eat Menhaden, including apparently at least one juvenile Bull Shark.

One juvenile Bull Shark stomach included this long skinny fish that's almost definitely some kind of eel. Since both Conger and American Eels can occur in Pamlico Sound (and one is considerably more of a conservation concern than the other) genetic ID will tell us which it is (or if it's something else entirely).

I maybe used the spare LEDs from my ROV mount to put underbody lights on the toddler's stroller.
