#365daysofbiking Making a deposit

August 29th – I travelled home through Aldridge early in the afternoon after visiting the bank, and I had stuff to wait in for. On the way past the brickworks at Stubbers Green, just where the marlpit fence runs near the towpath, I noticed this curious instrument.

It’s a temporary placement, for gathering data about but deposition from the quarry and brickworks. It’s called – I kid you not – A frisbee deposition gauge, and it collects dust from the air and rain, which it collects in the vessel at the bottom of the tripod. There’s thin crosswires to stop birds landing on it, and a course foam pad to stop large debris like litter and leaves clogging it up.

Several of these instruments appear to be positioned around the site, presumably to test compliance with relevant pollution law.

It’s a fascinating area of environmental science and engineering and interesting to see it in use locally.
