HTML and other WEB stuff (and additional miscellaneous info!) I recommend that you use the Safari web browser on the Macs. It has the ability to block pop up windows (under the Safari pull-down menu) and I have found it to work well on almost all websites. Your files on the IGPP server are accessible to the outside world via the web, provided you have given read permission. The address is: http://igpphome.ucsd.edu/username/ The default place to put web sites is in the Sites directory, i.e. http://igpphome.ucsd.edu/username/Sites/ There is a default page there from Apple that provides instructions for getting things set up. Many students have set up and designed their own websites and you are encouraged to do so as well! Now if we could only get all the faculty to do this.... Prior to our setting up the IGPP server in this way, we had set up various directories to be visible to the web. To create a web site on the Fishnet machines, you needed a directory in /net/mahi/https/docs. For example, my web stuff is contained in /net/mahi/https/docs/shearer and its subdirectories. I have not yet transferred everything to the IGPP server. Websites are written in HTML. This is not a WYSIWYG language. To see the original HTML source code for any web document, use "View Source" under "View" for Safari ( or "Page Source" under "View" for Netscape Navigator, etc., presumably Explorer and other browsers have a similar command). To download an image, click on the 3rd mouse button when the cursor is within the image. This will allow you to save the image to a file. Thus, you can easily steal images from any site on the web! For example, I went to a Clint Eastwood fan's site to get the picture of Clint that is on the IGPP Journal Club web site. The following section only works on the Suns. Mac users please skip! *************************** Sun only section *********************** Most web images are in "gif" or "jpeg" formats. To view and/or edit jpeg or gif files, run xv, e.g. xv myimage.jpeg You can convert a Postscript file to gif using the convert command: convert file1.ps file1.gif This has various arguments (see "man convert") that allow you to do things like change the size: convert -geometry 50% bigplot.gif smallerplot.gif The default resolution for convert is fairly coarse. You can increase the resolution with the density command: convert -density 144x144 file1.ps file1.gif will produce twice the resolution as the default (72x72). ********************************************************************** On the Macs, the Preview program can be used to look at jpeg and gif files. Indeed, it is likely the default application if you just double-click on the files. I currently use Adobe Illustrator to convert from Postscript to other formats. However, this can be cumbersome, so it would probably be good to get the xv and convert programs installed on the Macs so that we had more options within the purely UNIX environment, such as using these commmands in scripts. Programs like Word now allow you to save your work as HTML files. There are also many tools and programs out there to help you design your own web sites. It is thus not necessary to learn HTML in detail. It is useful, however, to at least recognize some of the basic commands. Here is an example from my HTML book: (test.html)
Greetings from

To preview a local html file (i.e., not accessible from
the web), enter file:filename within the Safari location
window. For example, the above file can be previewed as
file:/home/shearer/CLASS/COMP/WEB/test.html
You can also do this from Open File under the File window
(or double-click on the file if it has a .html suffix).
Browsers also usually contain editors that allow you to
edit html documents if you do not want to use a separate
program to do this.
Note that most commands begin with <***> and end with ***>.
Paragraphs are separated with
. Links to other web sites are defined as, for example, O-Reilly & Associates "O-Reilly & Associates" will print on the screen and be highlighted or underlined by the browser so that the reader knows he/she can click on it and go to the web site (http://www.ora.com in this case). You can look at the source for my home page (http://mahi.ucsd.edu/shearer/index.html) to see more simple examples of html commands. Most of the notes for the computer class are written as ***.txt files (e.g., fortran.txt, etc.). In this case, they appear exactly as they are written as simple ascii files with no HTML formatting. One thing that my HTML book emphasizes (and I agree with) is that the HTML philosophy is to let the browser do the work of formatting. Thus, one should not expect/attempt to have too much control of what the displayed page will look like. Keep it simple and readable! Many commercial sites, of course, completely violate this idea. They are formatted so that if your browser winder is too narrow, things are cut off on the right side rather than simply wrapping to the next line. They are also full of extraneous graphics that lengthen the download time. LIBRARY WEB TOOLS You can search for books and journals at the UCSD libraries from the library website http://libraries.ucsd.edu or from the SIO library at http://scilib.ucsd.edu/sio/. The "georef" index of geology and geophysics papers is accessible from the SIO library site. From this site, your can search by author, title, etc. This is handy, for example, when you can remember one of the author names but not the title, journal or year for a paper that you want to find. Alternatively, you can telnet to MELVYL or ROGER directly, e.g., rock% telnet melvyl although this is not as nice as the web version. From within melvyl, you can go to the "georef" index of papers by entering "georef" To see where a paper has been cited, check the "Science Citation Index." This used to be available in the SIO library in big volumes (are they still there?). Now you can go to http://isiknowledge.com and click on "Web of Science" to find out the same things. You can also use this to search for papers, but the results will include lots of biology and medical papers as well as geological. Unless you search for a very unusual last name, I think georef works better to search for particular papers. For example, in my case, there are P. Shearer papers in webofscience for: Sex-related differences in the tolerance of Oriental fruit moth (Grapholita molesta) to organophosphate insecticides and Secondary acute myelogenous leukemia in patients previously treated for childhood renal tumors: A report from the National Wilms Tumor Study Group By marking a selected paper, one can find out how many times it has been cited by other papers. So far, I have not figured out how to list the papers that cite a given paper but there surely must be a way to do this. SOCIETIES and JOURNALS You should consider joining AGU (American Geophysical Union, http://earth.agu.org/) or SSA (Seismological Society of America, http://www.seismosoc.org/). Both publish journals (JGR and BSSA, respectively) and offer discounted rates for students. AGU also publishes EOS each week; this contains timely news and job offer postings. DEADLINES The big meeting around here is the Fall AGU Meeting in December every year in San Francisco. The abstract deadline is usually in early September for this meeting. The NSF deadlines for the Earth Science panel are June 1 and December 1. Ocean Sciences have different deadlines. Your advisor is likely to be quite busy at some of these times!
