Jill Rowling has been caving since 1988 when she was introduced to the hobby by her (then) fiancee, Dr Mike Lake. She is a member of both Sydney University Speleological Society (SUSS) and the Sydney Speleological Society (SSS). Ever since she was taken to a tourist cave as a child, she has always wanted to know what was the cause of the shapes and patterns that she saw.
Frustrated with the usual handwaving arguments for explanations as to the origin of speleothems, she is trying to find more precise reasons for the existance of a number of speleological features such as helictites and microgours. Like the growth of speleothems themselves, this journey of discovery will take some time. Along the way, there have been a few discoveries such as Ribbon Helictites, the study of which has led to a better understanding of the structure of "normal helictites".
Jill has caved in Australia in NSW, Victoria, Tasmania and South Australia. Overseas she has had brief caving trips to caves in Fiji and Switzerland. She has visited Australian show caves in NSW, Tasmania, South Australia and Western Australia, and overseas in Austria, the Czech Republic, New Zealand, Slovakia and Slovenia.
Jill received a Master of Science degree from the University of Sydney in 2005, on the topic of "Cave Aragonites of NSW". The thesis (book) is in Fischer Library and is available on-line in the Digital Thesis Project.
When she is not fussing over cave matters, Jill can sometimes be found gardening or knitting depending on the weather. She occasionally gets involved in cave politics with the Australian Speleological Federation. Pet hates include vertical cave trips involving squeezes, photography and CO2 all at the same time.
Jill is also an Electrical Engineer (BE, NSW Institute of Technology, 1986)
with experience in data communications, disk controllers and microcontroller
She is currently employed as a Systems Administrator, looking after several
Sun (Solaris 7 and 9), Linux (Red Hat) and Windows 2003 servers.
Activities at work include maintenance of Electrical and 3D CAD systems,
OS patches and
updates, web site maintenance, tape backup and tracking license renewals.
Projects include filesystem consolidation to a SAN, and some Active Directory
At home she uses various computers: Debian Linux on Athlon and PowerPC, Solaris 8 on Sun Sparcstation and MacOSX on PowerPC.
She has been known to frequent meetings of the Sydney Linux Users Group
She helped Judith and Brian Rowling set up their Web site at Rowlingstock Productions.
To prepare these web pages, Jill used a mixture of tools running on Linux: Konqueror, Netscape, Quanta, The Gimp, xfig, latex2html, gvim, vim, vi and occasionally ed.
The colour scheme is still based on the colours you see around cave entrances, while keeping to pastel shades.
The original pages used frames; I decided to ditch them and re-do the navigation using CSS, as some people complained about the frames, and I got annoyed with button images taking ages to download on a dial-up. The only problem now will be with older non-compliant web browsers such as IE5.2 on MacOSX (Mozilla and Safari are fine). The differences should only be cosmetic. The pages load up very quickly now with a text-only browser, and the navigation should be relatively straight-forward. Someone didn't like the colour so it's a bit lighter. Some people requested a search facility... may I suggest using an external one. The original hyperlinks should still work, so you should not need to update your favourites. I may have updated the content though, so if you copied the page then your copy may be different of course.
I've added a few more topics and given the Articles their own page.
