Frequently Asked Questions (and answers!) about this WWW server

We have figures, photographs, a little text, and a database. Specifically:

• The lithologic column describing the Kahi Puka drillhole #1, which shows the depth in the hole, the rock types encountered and the units into which they have been divided (henceforth lithologic units), the two sets of boxes into which the core was placed for storage, and the drilling "runs" (trips up and down the hole with the coring tube).
• Photographs of each Working Box of core (Core Boxes), which are kept at Caltech. These are available in two forms -- raw (straight off the photo-cd), and annotated (marked with the units and unit boundaries, sampled areas, and regions of interest). All of these are GIF images, 250-300 kilobytes in size. Scale and color control patches are shown.
• Photographs of each Archive Box of core, which are kept in Denver.
• Browse images of thin-sections of many lithologic units, captured in ordinary light with a 35mm slide scanner.
• Data describing each lithologic unit as recorded during on-site sample processing. Information about contacts, phenocrysts, groundmass, vesicles, alteration, veins, fractures, color, etc. are retrieved by a simple database program and returned to the client in tabular format.
• For public interest, a press release and the figures from Ed Stolper's 1994 Spring AGU talk.

There are two ways to find and download information from this server. The first is via the Sensitive Maps of the Lithologic Column. If you have a WWW client program which can return the coordinates of mouse-clicks (like NCSA Mosaic 2.0 or later), then clicking on the rectangle representing a box of core sends you the photograph of that box, and clicking on a lithologic unit or unit number gets the lithologic data for that unit, including a pointer to thin-section browse photos, when available. The second way to find stuff is from simple directories, which list all the available photos and data files. Pointers to both access methods are on the Hawaii Project home page.

Nobody was downloading them, and the annotated corebox photos seem to serve all known purposes. If some feature you really need to see is concealed by an annotation, let us know.

Because nobody has asked them. I could sit here and think of questions, but I wrote this server, so my questions would probably be different from yours. If you don't understand something, PLEASE ASK, so I can anticipate what will confuse other people. Then I can either explain it here or fix it. E-mail your questions to paul@expet.gps.caltech.edu, or go to my homepage and fill out the comment form.

It was created without permission from the people who would have to service the sample requests. When requests did come in, nobody could be found who could commit to do the sampling for all requests that might come in. Thus the archive will be operating on a self-serve basis. Qualified investigators should contact Ed Stolper (ems@expet) or Mike Baker (mikeb@expet) for details about coming to Caltech to take samples.
