You might assume that Lizard Island is pristine, but it's not immune from the effects of litter. Unfortunately it was all too easy and fast to collect this haul.

Loving the patterns in this natural rock shelf off Jervis Bay, New South Wales! Any geologist or geomorphologist out there who can shed some light on how they form?

Some of the ongoing 🛰️🧪 at #NOAA❤️ is illustrated here with an example of automatic detection of dust from the aerosol remote sensing group.
Aerosol detection product (ADP) from the ABI sensor on @noaa.gov GOES-East satellite highlighted the deadly dust storm (yellow) moving across Texas, Oklahoma & Kansas and smoke (lavender) from fast-growing wildfires in Oklahoma on Friday afternoon 14 Mar. @noaacomms.noaa.gov @sangasso.bsky.social

Kaikōura (NZ) literally means "eat crayfish" (kai = food/eat, kōura = crayfish) in Māori, making it a seafood lover’s paradise! It’s also one of the best places in the world to see sperm whales year-round!

🚁 Matrice 4 Enterprise vs. Mavic 3 Enterprise – Which one wins for drone mapping?
🚨 Bottom line: If you’re choosing between the M3E and M4E, the decision comes down to cost vs. capability. We break it all down in our latest blog.

A review of the Matrice 4 Enterprise (M4E)
We tested the DJI Matrice 4 Enterprise, putting it through its mapping paces and comparing it to the Mavic 3E in capabilities and price.

☁️Cloud computing at it's best haha :) With most pixels classified at cloud more than 70% of the time at our study site in the Torres Strait, we've had to get creative and use 193 images over two years to build a cloud free Sentinel-2 composite for habitat mapping

All maps are wrong, but some are useful! My reefs of interest were missing from the Autel remote controller mission planner. Thankfully we had other data on hand on GeoNadir that we could use for planning to import!
