A few couesi (?) around, but they've been running away as we try to collect them. An old coffee can. Beautiful burgundy disk with fringe just floated past. Lots of psolas.#basket star on a coral - beautiful.closing up crab trap, no more collections (box is full). Slope is gentle, rocky with thin sediment. Lots of sponges everywhere, corals, squat lobsters.seeing a bunch of really small squat lobster (?) hiding in rocks; no way to grab one (too small).

Very small chionoecetes (?) on a huge white sponge - no chance of collecting it.{spider crab, missing 3 walking legs on right side. Lots of creatures that look like stalked mussels on rocks (brachiopods?)We're at 125 m and it s starting to get a little bit dark. We're tilted downward somewhat. We had some trouble sinking from the surface, but Bruce motored us down somewhat, now he s adjusting the trim.{The first bioluminescent particles are appearing at about 150 m. Probably little ctenophores. We re getting quite a show of bioluminescence now. Sparks, and squiggles, and chains, round things. Some are obviously ctenophores and jellyfish, others I can t make out what shape they are. You can gauge your descent rate by watching them go by. Otherwise it s pitch black out now.We re about 50 m off bottom. We started seeing grenadiers at well over 100 m off bottom. At this depth were seeing a few pasiphaeid shrimp, and quite a bit of marine snow.IThese are pretty angular rocks. Are these rafted? How do they get here. Randy: They just tumble down.It s a scree slope basically. We re on the bottom at 2735 m on a slope that s going up at about 15 degrees. Our heading right now is 11 degrees, and it s a fairly sedimented slope with quite a bit of broken angular cobble on it. More sediment than cobble. A few small corals here and there. Still waiting for our location. Not a lot of current here, just a little bit. Looks like its going to our left.We re sitting on the bottom checking out the substrate for a potential push core, but there s not a lot of sediment here, so we ll try it further up the slope.OApparently there s a spider crab out the port window on Randy s side at 2730 m.wAt last we re finally moving, 3 hours after leaving the surface, we ve left our drop p< oint and started moving uphill. We ve got some interesting object in front of us on the 3-chip camera, I would say its some kind of sponge. Looks like a large fungus.ZNow we have a Macroregonia at 2732 m in the main camera. The crab was at a time of 19:05.uCrabs on the right side at the same depth. These look like small ones, about 3 inches across, legs maybe a foot long.19:05:08. Why isn t my clock updating? The clock isn t updating. By my watch it is 19:15 and we re trying to do a sediment core. Still at the bottom 2727 m.I m seeing Macroregonia about 1 per minute. Most of them appear to be juveniles with small claws. Most of the corals we re seeing here are white branched types, look like little beads on a necklace [pipe cleaner corals]2678 m 19:47 We ve got a coral sample in the biobox after a couple of tries. Pilot dropped it a couple of times. Now he s picking up the second sample and putting it into the biobox. That one was a lot simpler. He says it s the other half of the same piece.2634 20:16 There s a spider crab on one of these white fan corals. It s a little bit too far away to see what it s doing, but I wonder if it might be feeding on it.2570 m. I saw one of the white branched corals that was partly denuded of its covering on some of the branches, and the white material seemed to scattered around rocks at the base of it, like it had been stripped off.2511 m. There are a lot of Macroregonia here. They re all small, claws are small. They look fairly new shelled, close to or walking on one of these white fan corals, on a very steep rock slope with a little dust of sediment on it.?Time 20:55, depth 2511 m. Small piece of white fan coral is broken, and parts of it appear to be stripped off. Those parts are covered with debris that is caught on the branches and just hung there. But it makes me wonder whether something has been picking at it, that might have broken it off or been feeding on it.PThere s my first male Macroregonia, subadult on a rock next to a piece of coral.At 21:15, we just updated the depth, it was reading the same thing for a long time, about 2460, but we were really at 2395. A reminder to check the record to see what it looks like at this location and time.?2373 m. Mostly solid rock bottom. [Pilot corrects the depth] 2360 m? OK. Still some white corals and occasional spider crabs. None look particularly big, none are adult males. Mac on the right about 15 feet away at the base of a white coral, facing away from it. I don t know what our depth is any more. 2337 m.A Macroregonia crawling over a white coral. Two macs about 6 ft apart hanging off the underside of a rock next to some white corals. There s a new kind of coral there, a pinkish one, highly branched. 21:56 We re going up a fairly steep slope 2281 m. [to Randy] What do you call this, Pillow lava, or something else [Randy agrees]. Theres quite a lot of white corals and occasional spider crabs hanging off the rocks, some of them almost vertical. zSomewhere around 2200 m, 2257 it looks like. We have some white galatheids, that look like munida, or something similar. Time 22:52, depth 2191. maybe . At the end of the dive, we re waiting for them to get a fix on us. I have not seen any Anthomastis on this dive, which seems a little strange because they were quite abundant on Patton Seamount at this depth range. I wonder about that.[End of tape].6Comments (Note, Times are ZULU, depths are unreliable)At 2398 m, time is 21:14.Alvin, Patton seamounton the bottom on Patton Seamount. Sandy gravel bottom with cobble 2-4" scattered about. A few small brittle stars on each rock , sloping slightly up hill. A few seastars, some 6" fish of some sort, maybe a rattail. Don't see any crabs yetRocky slope with a shallow incline, fairly sedimented (pilot: sporadic biology). I see some sea cucumbers, some sea stars, a few crinoids. ^There are lots of rattails here of all sizes. Sandy bottom lots of gravel up to a foot in size;Oh a squid just inked us, theres ink coming up past the window. I don't see the squid, but there's ink everywhere. You must have hit him with your thrusters or something. There are little red crabs on the rocks here, they look like Munida to me, a little squatty pinch bug, fairly numerous, one every 3 ft or so.^I see a large dead sponge out my window and underneath it what looks like an Oregonia bifurca.on this rock slope theres a very delicate white coral with single polyps, growing right on the rock. The polyps come up about an inch, and it looks like they are growing off a little chain that grows along the rock.there are small king crabs here, probably lithodes couesi. We may have one in the basket, and theres one scrambling away from us in the distance.There are little crabs sitting in crevices under boulders, I cant tell what they are. They are not spider crabs, well they could be but I think they are probably Oregonia or something else. WWe've been trying to catch a crab, but it got away. I could see pretty clearly it s a small scarlet king crab, about 50 mm across the shell, juvenile, maybe subadult.HI can see more scarlet king crabs about the same size on the rocks here.I'm seeing numerous small majid crabs poking out from under the rocks. I cant tell if they are Macroregonia or Oregonia bifurca.1I see my first mushroom coral here [Anthomastis].Another small lithodid, looks like a scarlet king crab. Same depth, another SKC about 2" across hanging on a rock. There habitat here is a mixture of sand gravel, and cobble, the largest is about 2 ft across, the smallest about 4 ".]There are small rockfish here with very large heads sitting on t<Bhe bottom amongst the cobble.vWeve been traversing a sandy gravelly patch with small cobbles. I have not seen any small crabs for about 10 minutes.GWe just got a second coral sample in the box for Amy [Baco], bin no. 2./Another juvenile L. couesi out the port window.zThere are sea pens here as well sticking up from the sediment. They have a bulbous base and they stick up like a feather.The impression I'm getting of small crabs at this depth is that they are not among the coral, but they are down in the cracks and crevices under rocks and between boulders, occasionaly on the boulders, that seems to be the place where most occur.There's a lot more life out here now, small pink mushroom corals. That s one of those long armed pinch bugs. We got plenty of them. They're a dime a dozen. Not exactly, but. Ah there's a cast exuvia of a pinch bug. Lots of psolus armored sea cucumbers with their tentacles spread out. And a number of the orange fern-;like corals, Mostly on cobble. A few small 4-6" red rockfish hanging around on the bottom.Heres a small about 1.5" Paralomis multispina at the base of a rock. Oh yeah, some very nice white gorgonians. That's your typical gorgonian, like youd see down in Florida almost.There is another small L. couesi, about 60 mm I'd say, off the port side, sitting on a small piece of cobble amongst the gravel.More small SKC, Id say about 30 mm on the large boulder, in the gravel field, where there arent many crabs among the gravel at all, just on the larger pieces of rock.We've stumbled across a grasping pair of Golden king crabs. This is the first pair of goldens we seen on this dive, we haven't seen any juveniles. And yet suddenly we come across a grasping pair. And it's deep for them.We caught a pair of grasping golden king crabs, just walking across a gravel bottom, no other substrate around. Phill caught them by grabbing the leg of the male, and it brought the female up with it, right into the basket.1Phill captured another pinch bug, one we have not captured before. It took a long time to set up for it, to get us in position and get the dipnet into position, but it all came into place and he scooped it up on the first try. And put the whole bag in the basket. I think its one we havent' seen before.1I saw a juvenile golden king crab on a steep sloping bottom, probably rock covered with sediment. A few outcrops, but its pretty heavily sedimented. Another juvenile king crab, maybe 40 mm on top of a rock about a foot high, sitting up above the surrounding substrate which is mostly sediment and cobble.More juvenile goldens now, hanging on boulders, and juvenile scarlets adjacent to them, so at least at this point they are mixed.SKC climbing up a boulder about 3 ft wide, surrounded by a cobble field. Juvenile GKC on a boulder about a foot across in the same area.ZTheres an adult SKC. They look a lot whiter down here, but that may be an immature color.Another juvenile golden on cobble, oh Boy, they're all over the place here now. (counts to 8). They're all over. Wonder if we could settle down here and just get some video of this. They're all over the place here. I think we found the mother lode, of juvenile GKC. They're all over the rocks here, in the cobble, at about 600 m. There are several per square meter here at this location, and interspersed with juvenile SKC, so they're not totally separated at this age, the two species seem to mix a little bit.2Chad: maybe they're mounting an attack against us.YNow we suddenly ran out of crabs didn't we. There's a few down there still, I see a few.VWe're starting to see a lot of crinoids, and seem to have run out of juvenile GKC now.Now the substrate has given away to solid rock outcrop. Its covered with crinoids, and these big brisingulid seastars, and the occasional candelabra coral. Starting to see some brittle stars, don't see any small king crabs in here though.@My first adult golden at this depth, except for the mating pair.>[submarine sounds: clicks, buzzing, whirrs} Submarine noises.
