I was out again yesterday, scrambling over the rocks below Boiling Pot Lookout in Noosa National Park. It is what biologists enjoying doing most, observing nature close up. All the better when you can sit-in your favourite marine pothole and see if the tide will eventually wash over you.<\/p>\n\n\n\n

Waiting for sea level rise.<\/p>\n\n\n\n

Before the moment of the highest tide, and before we had even made it around to the platform with the marine potholes, I found myself in the water, walking out to see where I had been just a few months earlier on the lowest tide for last year.<\/p>\n\n\n\n

I swear, just a few months ago, I could walk right across here. \u2026 remembering August 2023.<\/figcaption><\/figure>\n\n\n\n

You might be inclined to think that we have sea level rise here in Noosa when you see these photographs, but it\u2019s actually just a case of the time of year and the time of day. Because you see, the sea level is very affected by the sea tides.<\/p>\n\n\n\n

The theory of the tides, and the maths used to calculate them accurately, was worked out by one man, Arthur Thomas Doodson, a profoundly deaf graduate of Liverpool university in the 1930s. So much good science was done back then when mathematicians, like Doodson, were encouraged to work from actual observations.<\/p>\n\n\n\n

Yesterday, I specifically wanted to be at Tea Tree Bay for the highest tide of the year, scheduled for 9.33 am, Saturday 13th January 2024.<\/p>\n\n\n\n

I always like to see how high the highest wave will crash against the platform with the wave cut notch \u2013 from a time of higher sea levels.<\/p>\n\n\n\n
