Dive R497  
      Dive Plan: This dive is at the extensometer site on the north rift zone of Axial. The elevator was deployed with extensometer#4 in one tube and 3 empty tubes. ROPOS will first take #4 out of the elevator and deploy it, then will recover the other four  
      extensometers that were deployed in '98 and place them in the elevator, where they will be recovered at some point during, or after, the dive. Two Imagenex lines will be run after the extensometer work, then on to CASM  
      At CASM site for sampling and observations: tube worm grab; suction samples of mats, animals, FeO (if any present) and vent fluid. Collect GTBs; recover Vemco and HOBO - all at CASM. Deploy MTR and sample sulfides at CASM as well.  
      Note: Nav fixes not edited in the logs. All fixes were logged, regardless of accuracy. Use the dive plots to determine actual positions. Only positions on NRZ are acoustic nav. All transit and CASM positions are ship at stern.

17 32 1 158 424216 5087322 Elevator with 4 extensometers aboard into the water at 10:04. Didn't sink. Have to recover to add more weight.  
17 32 1 158 424216 5087322 10:50. Elevator back on deck. Weights had fallen of.  
17 32 1 158 424216 5087322 11:55. Elevator back into the briney. There is one extensometer onboard. Idea is to take that one down and deploy, recover others to surface for refurbishing and redeployment.

7 42 1574 285 420638 5095228 Ship heading is 25 and we've driven 50 m since the point we set down.  
7 42 1574 284 420638 5095228 The stern of the ship might be right over where this vent is.  
7 45 1574 288 420638 5095228 We're going to let it pump for 3 or 4 minutes, temperature is jumping between 1 and 16 C.

7 56 1572 280 420638 5095228 The ship has caught up with us so we're going across to the other side then drive north.  
7 58 1573 2 420638 5095228 Proceeding north, we're at the bottom of the fissure.

8 9 1572 9 420638 5095228 We're going to run north for 20 m, then go west to locate the fissure again. We just went in a nice little circle.

8 12 1572 18 420638 5095228 We're going north again.  
8 13 1570 17 420638 5095228 We see the chimneys! These are the lamphere chimneys, we think. We're of on the west side of the fissure still.  
8 14 1571 88 420638 5095228 Lamphere chimney R497-43
8 14 1570 94 420638 5095228 We see the chain that Verena put on a chimney in 1983. We can see lava lapping up on the bottom of this chimney.

8 16 1571 273 420638 5095228 We're at the fissure again- looking for T&S.  
8 18 1572 27 420638 5095228 A little bit of sulfide on the wall - we're right on the rim.  
8 19 1573 21 420638 5095228 We're lost.

8 26 1570 46 420638 5095228 What's the funny white-shaped donut looking thing?  
8 27 1568 23 420638 5095228 Going a little bit further north, Steve thinks we're cutting through the caldera wall. So we're turning around and going back.  
8 29 1577 194 420638 5095228 Metaliferous sediment again.  
8 30 1574 156 420638 5095228 Old sulfide - bizarre old sulfide.

8 34 1578 203 420638 5095228 Returning to the cage for tether management. The tether is caught on something.  
8 36 1543 150 420638 5095228 Keith had to go southwest to get back to his cage. The tether is ok.  
8 37 1546 141 420638 5095228 Going back down.  
8 39 1571 132 420638 5095228 We're going to go southeast now from the cage.

8 46 1576 77 420638 5095228 Lateralling to the north to get some more tether out.  
8 47 1573 82 420638 5095228 There are a few signs of hydrothermal venting here.  
8 47 1571 81 420638 5095228 Moving the ship 40 m to the east.  
8 48 1574 92 420638 5095228 Looks like there might be some hydrothermal venting? Maybe it's just staining. Quite glassy.

9 6 1548 270 420638 5095228 Going back down to the bottom again to look for this sight.  
9 7 1575 270 420638 5095228 It looks like we're in the right terrain this time.  
9 9 1572 276 420638 5095228 Moving ship 30 m to the west - we think we've got it. Lots of dead worms, maybe some are alive.  
9 9 1572 277 420638 5095228 We're at the fissure waiting for the ship.  
9 11 1573 273 420638 5095228 We see some live tube worms, some dead.

9 14 1580 3 420638 5095228 We're down in the deepest part of the fissure. Tube worms, metaliferous sediments. Need to move the ship another 10 m to the west.

9 20 1586 12 420638 5095228 The wall is starting to pinch in.  
9 22 1582 24 420638 5095228 We have the east wall in site.  
9 22 1579 17 420638 5095228 Looks like we're back in the caldera, looking at the brecias again. There is speculation that we're back where we were before, which is too far north.  
9 25 1581 196 420638 5095228 Going back to the cage - saw the clams again.  
9 26 1583 188 420638 5095228 Actually we're going back to the position of the cage.

        was floating behind the ship. We recovered the elevator and proceeded to CASM Vent Field. 17 samples were taken t CASM (suctions for animals and fluids), and tube worm grabs. After many hours at CASM we returned to the NRZ extensometer site.  
      The elevator was redeployed and one extensometer was placed in the tube. We lost power to the sub again and the dive was aborted.
