Looking at past dive data from Leg2 ROV01 & ROV02, the area to the southeast in this ROV dive plan image was explored during ROV02. This plan covers the most waypoints in areas that have not been explored. From the sulfur & shrimp wall vent site we will move laterally, transiting in a southeast direction along the northern slope of the crest, crossing over the summit (WP6) towards the easternmost point (WP5), and then heading in a northwest direction laterally along the southern slope of the crest towards WP7." 2010-07-29 02:21:50 okeanosexplorer we have reached bottom 2010-07-29 02:22:07 samanthazelin Seattle ECC- Dave Butterfield, Ed Baker, Yusuf Surachman Djajadihardja, Sam Zelin, Ellie Bors and guests. 2010-07-29 02:23:34 elizabethsibert For reference, here are the logging codes for the dive.

A cannot rule out the possibility that its some sulfur precipitation from the plume that settles in pockets, especially since we see similar particles in the water column. 2010-07-29 06:03:47 PMEL ECC I speculate that fluids circulating within the porous sediments are driven by the volcanic heat and addition of magmatic acidic volatiles, e.g. sulfur dioxide and carbon dioxide. 2010-07-29 06:04:37 PMEL ECC the acidic fluids dissolve the rocks and pick up high levels of iron, which can be oxidized from Fe-II to insoluble Fe-III when the fluids mix with seawater. 2010-07-29 06:05:21 PMEL ECC microbes living at an interface can extract energy from that oxidation an accumulate organic material mixed with iron oxides/hydroxides.

Samples showed sulfur, iron, and diverse microbes (not Archaea). They also formed in these same patcy configuration- between rocks and down in slight depressions....anyone know how these form? 2010-07-29 06:21:52 okeanosexplorer they are also very very similar to what is found in the main cone of Brothers caldera 2010-07-29 06:22:07 PMEL ECC very smooth here, no solid rock outcrops 2010-07-29 06:22:22 okeanosexplorer I do not know if the composition of those has been examined 2010-07-29 06:22:42 okeanosexplorer increasing the speed to 0.2 knots 2010-07-29 06:22:46 timothyshank I don't think so, but they are all "eruptive seamounts"... 2010-07-29 06:22:50 okeanosexplorer hdg 274 2010-07-29 06:23:34 okeanosexplorer is that the same as silicic volcano? 2010-07-29 06:23:37 eleanorbors were those Tubes POL? 2010-07-29 06:23:59 PMEL ECC No, not the same as silicic volcano 2010-07-29 06:24:23 okeanosexplorer ok, thanks 2010-07-29 06:24:39 PMEL ECC All volcanoes that are either erupting actively or have magma very near the seafloor and probably have magma degassing happening 2010-07-29 06:26:18 okeanosexplorer OK, get it, so silicic is just an indicative of the chemical composition? 2010-07-29 06:26:45 timothyshank so, any explanation for the patchiness of these "sulfur cobbles"? 2010-07-29 06:26:52 PMEL ECC yes, chemical composition of the rock, i.e. basalt-andesite- rhyolite, etc 2010-07-29 06:28:39 okeanosexplorer OK thank you, I had understood that the eruptions of silicic volcanos are often the most violent, is that true? 2010-07-29 06:29:00 samanthazelin seattle stop recording gefn008 sd5 2010-07-29 06:29:04 jamesholden Patches may be due to discreet points of diffuse venting beneath the sediments that percolate up. Wild speculation at this point. First I'd lie to know the phylogenetic and elemental composition as well as EM of the structure. 2010-07-29 06:29:07 samanthazelin seattle start recording gefn009 sd5 2010-07-29 06:29:25 timothyshank Summary: we have been jogging east and west on our way to WP5 (skipping WP6 given an eastern jog off track that made a direct transit to WP6 more feasible). It's not clear why the northeast to southwest jogs are happening repeatedly. 2010-07-29 06:31:54 timothyshank If the distribution of the patches were due to diffuse venting beneath, then why are the clams not aggregating in their distribution - it's just the opposite- the clams are "evenly" distributed. 2010-07-29 06:32:03 timothyshank current is to the Northwest 2010-07-29 06:32:40 catrionamunro much larger patches here 2010-07-29 06:32:56 okeanosexplorer yes, that is a good point, but alo most of the clams that we have seen lately appear to be death, could that explain their "even" distribution? 2010-07-29 06:33:01 elizabethsibert Would it make any sense to zoom on one of those patches? 2010-07-29 06:33:09 okeanosexplorer *dead 2010-07-29 06:33:37 PMEL ECC we have zoomed on one previously, and were not enlightened 2010-07-29 06:35:00 timothyshank Agreed- don't want to zoom in- want to get on line with the waypoints- Another idea is that these patches were once within a much larger patch and that larger patch is receding to form isolated patches..... 2010-07-29 06:35:50 PMEL ECC yes, possibly the material is self-sticky and just accumulates in patches 2010-07-29 06:36:23 okeanosexplorer northern slope of the crest, heading SW, has patches of yellow fluff (either microbial aggregations + iron oxide, or sulfur, perhaps both) and fields of clams (Calyptogena?) many of which appear to be dead, current depth 1878, coordinates 4d 40.495'N 125d 5.3815'E 2010-07-29 06:36:27 PMEL ECC i.e. nothing else around is as sticky 2010-07-29 06:36:37 timothyshank Santiago, any reason why we seem to be going east and west more than southeast? just taking a long time - now almost due east of WP6 by 35m. 2010-07-29 06:38:05 timothyshank I like the sticky idea....although when you blow them with the thrusters, they roll away as little balls....but I guess the stickiness forms the little balls.... 2010-07-29 06:40:06 okeanosexplorer I have been wondering the same.... I have asked the pilot multiple times to head SE but the ROV keeps oscillating all over the place 2010-07-29 06:40:47 okeanosexplorer according to the pilot te terrain is changing and he wants to give the sled an opportunity to catch up.... 2010-07-29 06:42:37 timothyshank There are terrain concerns here.
