Secchi Drawings


As a part of my residency at the Ecosciences Precinct I got the opportunity to go out on one of the data collection boats. They started collecting water samples just off Sea World and stopped about 13 times at various points all the way back to Jacobs Well. The analysis that I found most intriguing was the use of an instrument called a Secchi disk, which is a way of measuring water transparency. It is a 30 cm disk with black and white quadrants and is lowered into the water until you just can’t see it. It is interesting because despite advances in technology since its invention over 100 years ago, it is still used as a standard today.

During this residency I was interested in employing some of the ways or techniques scientists use to see the world to portray ‘a scientist at work’. I’m particularly interested in the connection between repetitive physical actions and the generation of knowledge.

The following images are a set of drawings that were generated using the ideas of transparency, movement, time and place.

  1. I’m watching your nephew repeating his scientific experiments to discover stuff. Last week he learned that every time you push the iPad stand across the table it squeals. We had five minutes of continuous squealing. When SuperGran’s hand is on the stand as well, it produces a screech. Even if you do it 100 times!
    I love the final installation you’ve made, too.
