The work of a geologist is a mystery for many people. We know about rocks and that is probably the extent of the average person’s knowledge of the field. It’s true, too. We do know about rocks (that is supposedly what 3 or 4 years of uni taught us).

But the life of a working geologist involves a fair bit of time watching drill holes be drilled. Whether you’re in minerals exploration or water drilling, a fair bit of time is spent simply watching a hole be drilled and monitoring its progress. For water bores, you are hoping for water (funny that!) When it does come, both you and the driller keep a close eye on the process, to ensure that the bore is drilled properly and that a bore is constructed that can be pumped for water in the future.

So, here below is a picture of a driller contemplating a successful bore. This post is really just a photo post. He’s referred to as “Waggie”, a reference to his actual name. I get on well with him and so I took this pic midway through the slower development process – we’re not actually drilling here, rather preparing the bore for future production, a process that requires observation and a little bit of contemplation. A reminder to any geos out there that a good drilling relationship is key to all good drilling campaigns.

At least we have some water!

And then, for me, as a geo, an example of why I want to come home (apart from leaving the flies, heat and dust). I have loved ones; my Wife; and my cat, seen here having a torrid day…

Greetings All!
What follows is my first guest post; and it touches on a topic in science communication that is close to my heart. Too often I find myself being irritated at a galah being described as a “Pink and Grey”. I cringe at people not being able to distinguish a monitor from a gecko. I particularly don’t like people worrying about crocodiles in places where they simply don’t live. Now; while I enjoyed a good education, I can assure you that these sorts of “real-world” lessons were not taught at school. I know what a galah is and I can even spot a wedge-tailed eagle from several hundred meters. I am who I am through an interest in the natural world that I have worked on through the years by asking questions and looking things up (in strange places like libraries, though the internet has replaced this largely in recent years.). I am not saying I am better than anyone in this, I am saying quite the opposite. IT IS HOW PEOPLE SHOULD BE. We were like this a couple of hundred years ago when people hung off every word from explorers. Somehow, in this age of information, we have lost the desire to have knowledge. It remains an important goal for science communicators, in my opinion, to inspire people to seek out information for themselves on the natural world. In some ways, it is not enough to simply teach.

Anyway, I owe my love of the natural world around me to my parents and grandparents. Thank you! Thus it is appropriate that my Mother be the first to guest post. A retired psychiatrist, she is also a naturalist. Her acuity of observation is second to none, and this is important if you are going to be mindful of your surroundings; another important lesson in life. If you’ve not heard of Dr. Kathy Hall, you have now:

Watch out for the crocs!

The visitor asked, “Do you ever see any of those white birds with yellow feathers on the top of their heads?”
Firstly, the visitor was Australian and had stayed at our place for several days on many occasions. He has also camped beside the Murray on a yearly basis for most of his adult life. Let’s give the visitor the benefit of the doubt and assume he was having trouble remembering the name Sulphur Crested Cockatoo or “Cocky” to most of us. Remembering the name is really not the issue, it’s asking whether we had any that is the problem! Cockies surround our house. They nest in the River Red Gums close by. They screech morning and night. They wake us even before the rooster crows. They fly in huge noisy flocks above us. They are omnipresent.
Probably even more bizarre was the comment of a 27year old Australian visitor who, when visiting the banks of the Coliban on a very hot day was concerned for my safety as I paddled on the shore-line in case there were crocodiles. She was serious.
Lack of wildlife observation skills is not unusual amongst our Australian guests, whereas, in general terms, our European visitors reach for binoculars, ask for individual names of species, and compare them with home wildlife. I often ponder the reason for this disparity. I suspect that the cause lies in less emphasis in this country on how we teach our children to speak and name things. If you point out a bird to a 2 year old and say, “Look, a bird!” in a minimalist way, that’s as far as the learning gets. If you say, “Look, honeyeater!” or “Look, Rosella!” or “There’s a corella!” the learning is already enriched. The trouble is, if the parent doesn’t know the difference, how can this enrichment occur? The knowledge, and interest, must be handed down through generations. Somehow we seem to have lost that interest and skill.
How often have you heard people refer to a pink and grey galah? They are all pink and grey, so ‘galah’ will do! It’s like referring to a black crow or a black and white magpie.
Although not true “twitchers”, R. and I have gained enormous pleasure from observing the different bird species that visit our property. Before we built the house and garden, while we camped in the paddocks, we observed 16 different birds. Since developing the garden, 5 years later, we have now observed 55 different species.
Some of you may remember [a previous piece of mine] about the pair of Australasian grebes who dominate our dam. They have produced two sets of chicks this season, four in each clutch. We are amazed to see them building a new nest so we may have a third brood soon.
Perhaps some may feel that being able to recognise different animal species is not important enough to worry about. I would counter that awareness of our surroundings and interest in the variety, characteristics and behaviour of living things around us is not only essential for the health of the planet, but also enhances our own pleasure and well-being. Not to mention our confidence while paddling in the Coliban!


-Kathy Hall, Coliban Springs.

Its been a while, but then science can’t be rushed, and much pondering over certain products made with water must be had first. For around 3 months now we’ve been doing this water exploration program and it’s coming to an end. I wrote about my experiences talking with local farmers and watching them wander around the paddocks with bent pieces of wire here. As I said, there is a certain comfort that this gives the farmers in siting a drill rig to drill a hole for their windmills. It’s not a cheap exercise, so when they commit, they like to feel confident that they’ve given themselves the best possible shot. When you can’t afford a hydrogeologist, and when it’s all you’ve known growing up; it is understandable that you’d see water divining as the way to go.

Scientists, such as myself, do not believe in water divining. Not because we simply reject that which we weren’t taught at school (which is a tempting retort from many who believe in pseudoscience). Rather because there is no evidence for its efficacy. Water divining has been subjected to a number of scientific trials and has failed to produce a significant result. It is, therefore, bunkum in scientific circles. No serious scientist or scientific consultant could use it professionally.

As I said in my previous post, however, there can be some client-liaison and political reasons for not rejecting it out of hand when in the field. It ‘smooths the water’ to let landholders do their thing and feel that they are influencing your scientific process. In fact, through this process, I have learned a lot about the land I’m exploring in and it has revealed numerous insights into otherwise obscured geological features. All this has aided my scientific exploration effort and I think bettered my hit rate. Of the holes planned and sited, the success rate through the program has gone from a predictable 20-30-odd percent to better than 50%. This may not sound too good, but sub-50% success rates in the terrain we’re in are not uncommon. In other terms, you could say that science and keen observation on the ground coupled with a relatively open minded approach to the landholders has enabled me to go from rank amateur in that terrain, to better than a water diviner in less than 3 months. The best water diviners have taken a lifetime to learn the craft and a require a lifetime’s experience.

So, let this be a little message to scientists who find themselves working with real people on real projects out on the ground where pseudoscience is rife. Don’t dismiss the pseudoscience out of hand and thereby fail to gather all the nuanced data that’s available to you. By all means disbelieve, as I do, but remember these are people you’re dealing with. If you get the opportunity to do it, take them through your scientific exploration process. You might be surprised how well they understand what you’re talking about (you shouldn’t be though, unless you’re one of a particular breed of condescending city-scientist), and you may just convert the odd one to the joy of good science well applied!
