05:44:37 Jul 08 '00	1525	106	423663	5088563	Waiting for a Ropos fix to find out where we are - WAIT!! There's the osmo sampler. We must be at Magnesia. There is no visible flow.
05:46:47 Jul 08 '00	1527	225	423663	5088563	A lot of iron oxides in the area. We are looking around, but it appears that the whole area at and around Magnesia is dead - no flow!

06:15:20 Jul 08 '00	1526	139	422989	5089166	Moving over lava pillars, sunken pits with jumbles flow on the floor. The whole northern part of the '98 flow seems to have stopped venting.
06:16:09 Jul 08 '00	1527	138	422989	5089166	Moving the ship to position for drive to Oldworms.
06:18:29 Jul 08 '00	1526	137	422989	5089166	Photo 8 of lava pillars between Magnesia and edge of lava flow (where Oldworms is). This is probably one of the primary eruptive fissures of the '98 flow.
06:23:10 Jul 08 '00	1524	134	423075	5089141	Ship is now starting to move.
06:25:00 Jul 08 '00	1524	138	423075	5089141	Heading to Oldworms located at 423785, 5088418, depth 1528m. Still going over lava pillars and collapsed area.

06:35:30 Jul 08 '00	1525	143	423745	5088494	Following the cracks. Found a few small tubeworms, and protozoan mat. More tube worms and blue protozoan mats covering large areas of basalt. This seems to be a fairly extensive area. Position: x=423750 y=5088454, depth 1523m.
06:40:02 Jul 08 '00	1525	166	423754	5088467	Dead clams about 50m from Oldworms				R547-027
06:39:42 Jul 08 '00	1524	165	423754	5088467	Bed of clams in same area. Looking to see if any are alive. They look all dead unfortunately, but some might be sleeping!

06:42:02 Jul 08 '00	1524	248	423763	5088456	Considering naming this new site "Blue Lagoon", but settled on BlueNose.				R547-030
06:43:02 Jul 08 '00	1526	208	425645	5087401	Tube worms at BlueNose.				R547-031
06:41:02 Jul 08 '00	1526	166	423758	5088462	More blue protozoan? Mat around crack. White mat seems to be right in the crack with the blue mat on the periphery. Now we are at a tubeworm bunch. We are going to call this site "Blue Nose" (Blunose).
06:45:12 Jul 08 '00	1524	285	423760	5088458	We were just pulled off site by the ship. Stirring up sediment, rising off the bottom until it settles and the ship repositions.
06:46:12 Jul 08 '00	1516	301	423760	5088458	This area, "Blue Nose", is 50 m to the NW of Oldworms.

06:52:32 Jul 08 '00	1525	328	423753	5088449	Blunose				R547-035
06:53:02 Jul 08 '00	1525	329	421633	5088895	Background temp. is 2.5. Limpets are right around crack openings with the blue mat on the top of the basalts. Tubeworms are nestled in the crack with some polynoids. Trying to get a good temperature measurement to see if it's worth taking a fluid sample.
06:57:02 Jul 08 '00	1525	329	423754	5088451	Now trying to measure the temperature over the blue mat. Moving the sub caused a bunch of floc to come out of the crack. Waiting for it to settle so we can see.
07:01:22 Jul 08 '00	1526	267	421649	5088911	Couldn't detect any temp. anomaly about blue mat. Moving SE towards Oldworms.
07:03:22 Jul 08 '00	1525	128	423759	5088447	Moving over pillows, some are blown out dotted with blue mat and white staining. Back into a shallow collapsed area. Spider crab.

07:06:48 Jul 08 '00	1523	83	423778	5088437	We think we might be at Oldworms. Picture 14 of a net on the seafloor wrapped around a pillow. It may be a fishing net.
07:08:38 Jul 08 '00	1523	109	423778	5088437	Tubeworms at Oldworms (?)				R547-037
07:08:38 Jul 08 '00	1523	109	423778	5088437	Photo 15 of big tubeworm bush. The tubeworms are very long and skinny and stick-like. Their plumes are out but they are not bushy. A lot of bacteria mat/floc. Ropos is fixing on this site at 20 m North of "Oldworms" - but the site seems to be a big one,

07:11:08 Jul 08 '00	1525	87	423790	5088438	Beautiful lava outcrop covered in limpets, blue protozoan mat, a few tubeworms and a vent fish (zoarcid). There is an opening with flow and limpets are stacked up to 10 on top of each other down into the flow. There are also a few galatheid crabs.
07:15:28 Jul 08 '00	1525	180	423789	5088439	Tried to get into this hole to sample flow, but Ropos couldn't reach. Moving on to another patch of tubeworms to find some good flow.
07:17:18 Jul 08 '00	1525	127	423784	5088433	Photo 16 of tubeworms in same area as above.

07:27:08 Jul 08 '00	1524	189	421713	5089003	Looking for a place to settle so we can do something about these two MTRs dragging off the purse.
07:32:30 Jul 08 '00	1523	153	423797	5088416	ROPOS has one of the MTRs in the port arm and the other still dangling.
