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.

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.

I made a display frame to store my ROV between deployments and I think I just accepted robot Jesus as my personal servo. @JoeyMaier

Playing around with OpenROV Trident at the University of Delaware. It's a little bot with a big vision and we're giving away 1000 over the next year to scientists, explorers, students, and adventurers.

I asked my toddler if she wanted her first code to print "Hello World" or make an LED blink.

She picked "Hello World".

I think my child is BASIC.

This is a modern circuit board by a major appliance manufacturer that wants $100 to replace it. The traces aren't even etched. It's basically a bread board.

In a dishwasher.

Are you surprised it failed?
