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 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 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.

17 31 1604 324 422391 5083043 Stopping the ship. ROPOS is 60 m NE of the stern of the ship - where the above fix was from. Moving ship 50 m to the east, then starting on a heading of 045.  
17 35 1598 56 422074 5085359 Bob thinks new flow is about 90 m wide. Waiting for the ship to move.  
17 41 1598 45 422074 5085359 We're moving again - heading northeast. On old lavas now.

17 49 1593 43 422206 5083150 Still on the old lavas heading 045 - lots of holothurians. Edge of a collapsed pit, into the new lava again? 2282, 3286 fix.  
17 52 1589 46 422276 5083225 Still in old pillow lavas - that jumbled bit of flow may have been a channel of new lava passing through the old flow.

18 18 1518 227 422825 5083759 We have been having some problems with the tether for the past 10 minutes or so. The ship is stopping so we can get back to the bottom.  
18 23 1525 23 422709 5083710 Back at the cage.  
18 27 1528 20 422709 5083710 Lost video on the sub. Is power down? The tether went again. Coming back up.  
18 36 1528 20 422709 5083710 Dive Summary: ROPOS Dive R494 was a continuation of the two previous dives, which were ended early.  
       The objective was to determine if the 1998 eruption was continuous between the northern, well-mapped area and the southern SeaBeam anomaly (visited last year on R465), and to map out the extent of the 1998 lavas.  
      This dive started about 800 meters south of the southern SeaBeam anomaly (1200 m south of the R465 dive track) on Axial's South Rift  
      The pre-1998 lavas were much older here, in general, than further north (near Bag City Vent), allowing the 1998 lavas to be easily distinguished. About 500 meters south of the southern SeaBeam anomaly ROPOS encountered a fissure with '98 lavas in the  
      bottom. As ROPOS approached the anomaly, the lavas overflowed the fissure and spread outward. This was clearly the surface expression of the dike that fed the eruption. North of the southern SeaBeam  
      encountered it again after we traversed back to the NE, about 700 meters NE of the north edge of the anomaly. The '98 lava here was ~200 m wide, but as we followed it north, it narrowed and eventually pinched out completely about 400 m further north.  
      This '98 lava is probably connected to the southern SeaBeam anomaly. The '98 eruptive fissure along this part of the SRZ was further to the east than we had expected, based on bathymetry. For example, it is 350 meters east of the large cratered mound  
      at 45 52.85'. ROPOS crossed the trend of the '98 eruptive fissure again, 600 meters further north and again young '98 lava. There was a big drained out lava lake in this area. '98 lava was followed another 200 - 300 meters along axis, and then ROPOS  
      crossed another 200 - 300 meters of older lava, before reaching the eastern contact of more new lava. The sub then traversed to the NW and was in '98 lava for ~ 800 meters. Once at the western contact, ROPOS turned to traverse NE, but did not cross '98  
      lava again. The traverse to the NE was never completed because ROPOS telemetry was lost and the dive ended prematurely. At the end of the dive, ROPOS was about 1000 meters NNE of the last crossing of '98 lava (and west of where it would be expected),  
      and about 1150 meters south of the traverse on Dive R493 (and about 100 meters west of the '98 lava contact from Dive R493 if extended southward). In summary, the '98 eruption appears to be nearly continuous from its northern end, south to almost 1 km  
      south of the southern SeaBeam anomaly. In this area between the two, the eruptive fissure changes orientation from north-south in the north
