Finishing the year with some beautiful satellite imagery: three decades of spectacular subtidal dynamics at the southern tip of Moreton Island in south-east Queensland, driven by the slow drift of sand northward along Australia's east coast.

Amazing. Thanks for sharing Robbi!
Quick question if you have a moment - the "white" patterns over land (lower right corner): is that sand mining?
Thanks!

@irenedf Yes, good spotting! I recently put together a similar animation focusing specifically on sand mining in this article below, focusing on Stradbroke Island just to the south: https://earthobservatory.nasa.gov/images/146669/saving-straddies-sand
Saving Straddie’s Sand

After seven decades, sand mining operations have stopped in Australia’s North Stradbroke Island.

@irenedf Sand mining has now been phased out there, so it will be fascinating to see how the islands recover over the next few years!

@SatelliteSci Thanks for the response Robbi! Fascinating time series. Thanks for passing on the additional animation. I shall show it to my students!
