rockfall took off all our clothes waterproofed everything in our pack and blew up stuff sacks so we'd had had enough air in the pack to keep it buoyant and then just started pulling ourselves along the edges here and as we went around these blind Corners notknowing what was going to be around the corner if we'd be able to get around this water at all uh we finally did
And going underwater, you can be very surprised how buoyant you are. So I would think I would sink, but I would just pop right back up.
The very first cephalopod was made by a shell. A buoyant shell. And that was what separated the early cephalopods from all of the other snails, and mollusks, and other clams and things that were living on the sea floor. And to understand how this happened, we have to go way, way, way back in time because cephalopods are twice as old as dinosaurs.
Elephants, fortunately, are very good swimmers. Very buoyant . So she swam back to shore. We got out. And I asked some locals.
Male #2: In this shot, and in the previous shots, it wasnít very obvious: are your cameras neutrally buoyant ? Cheng: Are cameras neutrally buoyant ? They can be made to be neutrally buoyant . Male #2: How about your setup?
But what I started to recognize from my own experience and then from the research is that people who hold their world with a great deal of wonder really are more buoyant . They're more resilient and able to withstand these big existential changes.
This is not exactly to scale because I didn't have just sort of infinite room to go off here. The forms that have buoyant shells are, of course, always somewhat limited because they have gas in their shell.
singing Only then did I see the other in congruities my eyes eyes were blue not brown my voice buoyant my physique way more buff than I ever planned to become and though I shared similarities with the man in the canoe as if Katie had tried to fit me into his mold the differences were clear there in the
This is a shot. Most of them are buoyant little things.
overall feeling of doom the Russian soul had come to claim her extinguishing all that was sanguine and buoyant all that was American inside her leaving only the Siberian steppes the crust of black bread the acerbic aftertaste of
It's stretched out and topped with a thick layer of sediment accumulated over thousands of years. Continental crust is thicker and more buoyant than oceanic crust, so it “floats” higher on top of the mantle. Combined with the thick layer of sediments, the ocean is shallower on the shelf, usually less than two hundred meters deep.
could be imported. And it would hopefully lead to a longer survival time for this lineage of shelled cephalopods. The last ones with that buoyant shell. And this listing or this possibility of listing cephalopods here is open for public comment.
Meanwhile, at convergent boundaries, plates move toward each other. When a dense oceanic plate meets a more buoyant continental plate, a process called subduction happens: the denser plate slides underneath the other one, returning that rock to the mantle. This is primarily thanks to slab pull: the gravitational force that yanks plates downward.
Anyway, so there's lots of stories told about sea silk, also known as byssus. and then swim back down until they were neutrally buoyant at that the depth they wanted to live.
But there's just a real difference. And then I thought well maybe here more buoyant in the salt water so you have less of your body exposed, so maybe you don't feel the water temperature as much or maybe the salt in the water blocks your perception of it.
taken a straw and put it in a milkshake, right, like annoying people do, well, my children do and the highly energetic material coming from around the black hole literally inflates bubbles in this atmosphere and the bubbles are buoyant . This is a gravitational system so it's just like a bubble in a milkshake or a bubble in the ocean floats up.
be incapacitated by hypothermia and drown. Also having less body fat means that cubs are less buoyant so it requires a lot more energy for them to swim and they have a harder time keeping their heads above the water, and of course that's particularly true when the ocean is rough.
He and Gagnon had designed the Aqua-Lung to be slightly buoyant in sea water because adding weight was simple and subtracting weight was impossible.
Taking a single breath from his tanks turned him from a negatively buoyant object into a positive one. His lungs, he realized were a sensitive balance
smashed down so deep your board comes up and it's it's called tombstoning so your board is buoyant you're not that buoyant
But you can see that inside the shell there are some little chambers. The chambers filled with the yellow color are sectioned off, separated from the rest of the animal, and they're filled with buoyant gas. And once enough of those chambers formed, the gas in them was able to offset the weight of the shell and the weight of the animal and lift it right up into the water
And once enough of those chambers formed, the gas in them was able to offset the weight of the shell and the weight of the animal and lift it right up into the water column. So that's what you see at the top there is the first real, true cephalopod that had a chambered shell with buoyant gas inside the chambers. It was able to move around in the water column and they were some of the first animals to really be swimmers.
This is not exactly to scale because I didn't have just sort of infinite room to go off here. And so once the shell goes internal, which is this little light colored thing, it's still chambered, it's still buoyant , it was still quite substantial for a long time,
Then you need all of this weight to keep all this equipment down there, because the cameras are extremely positively buoyant .
Cheng: Mine is slightly negative. Historically, manufacturers have not paid attention to buoyancy, and they should. Video housing manufacturers do pay quite a lot of attention to buoyancy. But if itís too heavy, it becomes very difficult to hold, so we will typically put closed cell foam floats on the setup to make it more buoyant until itís where you like it. If itís totally neutral, I find that it also becomes difficult to use for stills.
Male #2: How about your setup? Cheng: Mine is slightly negative. Historically, manufacturers have not paid attention to buoyancy, and they should.
