Local Marine Discovery Centre 3rd in National Reader’s Digest Environment Award
On Sunday 21st October Star of the Sea School’s Marine Discovery Centre(MDC) was recognised with a Highly Commended Award for its innovative environmental project. The ceremony was held at Taronga Park Zoo, Sydney and the Centre’s Project Officer, Tim Hoile, represented the school.
The Centre received a prize of $5000 to assist with its development.
The judges highlighted the fact that the Centre is currently booked for over 15 months in advance, the "Leafy Seadragon Marine Education Curriculum" packs developed by the Centre were distributed to every Primary School in South Australia and the 30 volunteers regularly assist with the project.
The School also received a "Water Hero" Award on Thursday 18th October which was presented by Minister for Water Resources Mr Mark Brindal MP.
I am personally extremely grateful to Philip and Margaret Hall, who are regular volunteers at the MDC as they always "have the children eating out of the palm of their hands" with their insightful marine life information.

My buddy counted 31 Triggerfish, Balistes capriscus, in the group I was photographing at a dive site called Stack Rocks, near Littlehaven, SW Wales and another pair of divers counted over 50 on a different part of the reef. Each year the Triggerfish gather around these reefs and stay for about a month before moving off. (Photo credit Robert Walker.)

I read our last Journal (No.11) with great interest and enjoyed all of the articles including the one by Alex about cuttles. I managed to check out the ‘Cuttlefish Capital’ website and was very impressed with the webpage. The cuttles at Whyalla featured on Channel 7’s "Discover" program on 30/1/01 and I was duly enthused. Three of Alex’s references were by Karina Hall from SARDI who was the guest speaker at our February meeting. I enjoyed her talk which featured overheads and slides. We also got to check out four cuttlefish slides from our Photo Index. There is an article about cephalopods in Sportdiving magazine’s Feb/Mar 01 issue (No.84). I am not sure of the title though. It could be "Fish & Critters", "Slick Armed Bandits" or "Cephalopods: lights, cameras, action!" Akos Lumnitzer is the author of the article which starts on page 89. Each page of the 3-page article features great colour photos.
"Longitude is the dramatic human story of an epic scientific quest and of Harrison’s forty-year obsession with building his perfect timekeeper, known today as the chronometer. Full of heroism and chicanery, brilliance and the absurd, it is also a fascinating brief history of astronomy, navigation and clockmaking. Through Dava Sobel’s consummate skill, Longitude will open a new window on our world for all who read it."
I’m hoping that you have all followed the recent BBC adaptation of this marvelous book, on the ABC. I have never had an interest in maritime history or horology, but this book is very readable and I highly recommend it if you have enjoyed the TV version. There is much historical detail available about the story of the four famous Harrison chronometers. And it was this great race to measure longitude through the use of a perfect timekeeper that first coined the term ‘chronometer’.
I have been so impressed by the story that I would very much like to make a special effort (the next time I’m in the UK) to see the clocks, now kept in the National Maritime Museum in Greenwich. I would also like to share a little of this fascinating story with you.
There are four Harrison chronometers, H1-4. H1 and H2 were the largest of his creations, as you may have seen on the BBC series, but Harrison refined his many innovative techniques to produce the beautiful masterpiece H4. Dava Sobel says "Though large for a pocket watch, at five inches in diameter, it is miniscule for a sea clock, and weighs only three pounds. Within its paired silver cases, a genteel white face shows off four fanciful repeats of a fruit-and-foliage motif drawn in black. These patterns ring the dial of Roman numeral hours and Arabic seconds, where three blue-steel hands point unerringly to the correct time. The Watch, as it soon came to be known, embodied the essence of elegance and exactitude."
Harrison grew up as an apprentice carpenter to his father. How his fascination with clocks began is something of a mystery, but one of his first timekeepers was a wooden clock. He was able to overcome the problem of friction and lubrication, by using special woods that were self-lubricating. During the first few years of his experimenting with horology Harrison invented several new devices, some of which are still in use today. Over forty years he became more of a mechanic than carpenter.
One of the major problems facing horologists in the 18th century was that of temperature affecting the metals inside clocks and watches and hence making them grossly inaccurate at sea. Harrison refined the understanding of how temperature affected different metals and used that knowledge to build compensating systems inside the Watch.
He was also a fine craftsman: "… among the spinning wheels, diamonds and rubies do battle against friction. These tiny jewels, exquisitely cut, take over the work that was relegated to antifriction wheels and mechanical grasshoppers in all of Harrison’s big clocks.
How he came to master the jewelling of his Watch remains one of the most tantalizing secrets of H4. Harrison’s description of the Watch simply states that "The pallets are diamonds." No explanation follows as to why he chose this material, or by what technique he shaped the gems into their crucial configuration."
There were many battles during Harrison’s lifetime between the astronomers and the horologists, for the coveted £20,000 prize, the winner of which was to be decided by the Board of Longitude, established under the Longitude Act in 1714. The Board consisted of scientists, naval officers and government officials. The fact that the British government was willing to award such huge sums for a practical and useful method of measuring longitude expresses the nation’s desperation over navigation’s sorry history.
I don’t wish to go into more detail, but merely provide you with a tantalizing glimpse into the history of probably the most important timepiece ever created. Curators at the National Maritime Museum do not allow H4 to run, arguing that it "enjoys something of the status of a sacred relic or a priceless work of art that must be preserved for prosperity. To run it would be to ruin it."
