    Dive R494  
      Dive Plan: Dive R494 will start about 1 km south of the SeaBeam anomaly site surveyed on R465 in 9198 and move north to map the limits of the 1998 lava flow and sample the young and adjacent older lavas.  
      Note: NO ACOUSTIC NAV THIS DIVE. NAV FIXES ON DIVE PLOT ARE SHIP AT STERN. X/Y ARE SHIP GPS.

8 24 1720 266 422291 5080340 Still moving west following the contact - weaving in and out - no fissure. Photo-123
8 26 1720 266 422291 5080340 The older flows are changing now into more lobate-like pillow forms.  
8 31 1719 270 422291 5080340 Moving the ship 20 m southwest.  
8 38 1717 248 422291 5080340 Moving ship 20 m to bearing 25 - around northern end of SeaBeam anomaly lava flow. Still unclear if an eruptive fissure extends to the north from here. Trying to find out by going west first, then will go northeast.  
8 45 1719 216 422291 5080340 Still looking at the contact-great contrast between old and new.  
8 47 1721 171 422291 5080340 Having the ship move 10 m to the south, then continue 25.

8 58 1720 172 422291 5080340 Quite a bit of this fragment material. Going south.  
8 58 1721 191 422291 5080340 Maybe these chunks are from when a pit collapsed. Crinoid. Photo-127
8 59 1722 171 422291 5080340 Contact with young lava, with pieces of glass on the old lava. could be due to a collapse. R494-76

9 5 1720 275 422291 5080340 We haven't found any evidence of a northward fissure along this east-west contact. Looks like the contact is trending southerly.  
9 8 1720 274 422291 5080340 Going back to the cage for tether management.  
9 10 1696 94 422291 5080340 Back in the cage, now we're heading back to the bottom.  
9 11 1717 37 422291 5080340 Now we're just going to follow the contact, but right now we're in the new lava. Heading north to look for the contact.  
9 12 1720 2 422291 5080340 We're at the contact again. Starfish on the old lava. Heading west.  
9 14 1720 276 422291 5080340 Continuing to follow the contact to the west.  
9 14 1719 275 422291 5080340 We don't see any more of those glass fragments.  
9 16 1720 277 422291 5080340 Approximately 60 m west of the ship's position.  
9 21 1716 276 422291 5080340 Moving the ship 40 m to 340.

9 29 1716 343 422291 5080340 Approximately 50 m ahead of the cage- the ROV is probably directly under the stern of the ship.  
9 30 1714 345 422291 5080340 A the edge of a collapsed pit of the older lavas. Some sheet flows. Quite a bit of sediment here.  
9 33 1715 345 422291 5080340 Lots of sediment here- lobate lavas under there. Kind of heading off axis so things are getting older and older.  
9 34 1714 350 422291 5080340 We've found a fissure. Taking a look in the fissure. Looks deep - looks pretty old. Clean straight sides. Photo-135
9 35 1714 47 422291 5080340 Deep fissure R494-80
9 35 1716 44 422291 5080340 This is a very deep fissure.

9 38 1714 349 422291 5080340 Older lobate lobes, lots of sediment between the lobes. Some sponges and anemones on the lavas.  
9 41 1712 346 422291 5080340 ROPOS is still right under the stern of the ship.  
9 42 1713 343 422291 5080340 Older lavas turning more to pillows - still about the same age, though.  
9 45 1713 356 422291 5080340 Looks like we see some of the glass fragments again on the old lavas. Hmmm. curious.  
9 47 1712 356 422291 5080340 Still seeing those little pieces of glass on the old pillows and in the sediment pockets. Must be something new nearby.  
9 49 1710 355 422291 5080340 Looks like there are even more little pieces of glass on the old flow now.  
9 51 1709 0 422291 5080340 Fine particulate glass pieces on top of older lavas. Heavily sediment. Fresh glass shows up dark. Photo-136

10 1 1707 1 422291 5080340 End of the 40m. Now we're going to go 50 m on a 045 course.  
10 2 1708 48 422291 5080340 The cage depth has changed to 1675 m.  
10 8 1707 44 422291 5080340 Looking for new lava.  
10 10 1708 48 422291 5080340 We're in a jumbled zone. Hard to see if the glass deposits are still present.  
10 14 1709 48 422291 5080340 Coming up on some pillars with intact roof.  
10 16 1708 44 422032 5080676 Back into collapse, pillars, some crinoids. Photo of crinoid on top of a pillar. Photo-138

10 22 1708 44 422032 5080676 seem to be on a slope that's going to the south.  
10 22 1708 52 422032 5080676 A neat white thing- a sponge?  
10 22 1708 55 422032 5080676 A sponge of a different shape R494-87
10 23 1708 49 422032 5080676 Really rough topography here.  
10 24 1708 46 422032 5080676 Spinous lava. Lots of sponges and such.  
10 28 1707 54 422032 5080676 A pretty crinoid. A valve or two in a little pit- a large beautiful pink crinoid.  
10 28 1708 46 422032 5080676 A valve in the small pit with an echinoid on the upper edge. R494-88
10 28 1707 42 422032 5080676 Out of the jumble into the lobate now.  
10 32 1706 49 422032 5080676 We've found another narrow fissure. Looks deep.  
10 32 1706 44 422032 5080676 Narrow fissure R494-90
10 32 1706 46 422032 5080676 The fissure is only about 20 cm wide. Fairly fresh breaking, but the lava is old.  
10 33 1705 45 425427 5080885 ROV is lagging just a bit behind the stern of the ship.  
10 34 1706 45 425427 5080885 Away from the fissure. In the older pillows and lobates.  
10 36 1703 45 425427 5080885 We're going down slope.  
10 37 1705 49 425427 5080885 A more collapsed area.  
10 41 1705 46 422243 5080933 Going to keep on this course for 50 m (045).  
10 43 1705 45 422268 5080947 Heavily sediment here.  
10 47 1702 45 422253 5080978 Very few tectonic features here
