Wonderful to be at #IGARSS2025 in Brisbane! 🛰️Hopefully a nice Take 2 from my first IGARSS in Pasedena, CA where I spent half of the conference locked up in COVID hotel quarantine!

I did a tour of the Spit Sand Bypass System a few days ago - it apparently pre-dates the Tweed Sand Bypass and was the first system like it in the world (the new backpass was hit pretty badly by Cyclone Alfred so is currently out of operation)

Had a fantastic time presenting our new #eotides tide modelling Python package at #CoasttoCoast2025 - couldn't have asked for a more relevant coastal setting than the City of Gold Coast, still recovering from the impacts of #CycloneAlfred!

New #DEACoastlines annual shoreline data for 2024 is now live! 🌊🛰️🎉
2024 was a relatively stable year for coastal change across Australia, with mostly moderate and balanced rates of growth and retreat across our coastline.

The slow growth of a large sand spit as it intrudes into Melbourne's Altona Beach, captured by #Sentinel2 🛰️
This spit has been moving towards Altona for about 25 years now, averaging 50 metres of growth per year since 2000. It's now over 1.3 km long with no sign of slowing down!

Optical satellite remote sensing is often suprisingly useless during extreme events like #CycloneAlfred- there's just too many clouds.🛰️☁️
We were recently lucky to get a rare glimpse through the clouds from #Landsat + #Sentinel2 at Mooloolaba Beach, Queensland - 25-45 metres of erosion since Feb:

The gradual increase in tide range from left to right? That's part of a longer cycle of long-period tide interactions that are especially pronounced in the Gulf - more context in the figure below:

^ This is for a site with a strong bias towards low tide imagery in Landsat and Sentinel-2 data. These biases vary greatly across the world's coastlines - a major challenge for coastal analyses that rely on #EarthObservation data!
e.g. a different site where overpass time is a bit less important:

An unintentionally hilarious bouncing plot, simulating how overpass time affects how well a hypothetical #EO satellite like Landsat can monitor the tide cycle! 🏀🛰️🌊
Dots = what the satellite sees when it takes an image. Each frame is a different simulated overpass time - e.g. ~10-11 am for Landsat.

I did a uni GIS course, but first really used it for an archeology project in Bulgaria: mapping soils and Bronze Age artefacts, and comparing our data against Soviet maps + spy satellite photography!
So a pretty exciting intro, which led me to follow up with a geospatial science PhD! #GISchat
