This sample includes abundant highly-vesicular<br />
spatter clasts as large as 7 cm. The finer portions of<br />
the sample are also mainly pyroclastic with spatter<br />
fragments, broken crystals of opx and cpx, rare limu o<br />
Pele and Pele’s hair, and some altered or crystalline<br />
rock fragments. S spherules are present but rare. Two<br />
gastropod shells (about 2 mm long) are present—one<br />
was alive and the other dead when collected. Both<br />
are heavily stained with Fe, as are some of the<br />
spatter clasts. The glass is gray colored. Used Rick's<br />
scoop sampler to get the sample. Location: about<br />
14m SE of Shrimp City. Not suspected to be zero<br />
age.<br />
Filtered bag #16. Shimmering water at Red Rock<br />
Ridge. Presampling temp=14 and still rising. pH<br />
around 3 and decreasing. Tmax=16.8 Tavg=16.4<br />
Vol=501ml. Stop 1605.<br />
Unfiltered bag #21. Same spot as sample 24. Pump<br />
stuck but started again so it's OK. Tmax=17.4<br />
Tavg=17.0 Vol=602ml. Stop 1610.<br />
Filter #10. Same spot as samples 24 and 25. Start<br />
Tmax=18.4 Tavg=17.7 Vol=2002ml. Checked pH<br />
again at end. pH ~2.7. Stop 1622.<br />
Piece of pillow with iron coating. Same place as<br />
samples 24-26. Not suspected to be zero age.<br />
Background water sample. Filtered bag #17. Took<br />
sample while moving away from Red Rock Ridge<br />
towards Hades at depth of 1193m. . May not be<br />
background since pH is still reading 3. Stop 1652. We<br />
are at Hades already.<br />
