Some more incredible coastal geomorphology, this time at Montgomery Reef in Australia's Kimberley region. These shifting sandbanks are driven by some of the world's most extreme tides, which rise and fall by over 10m! (30 years of #DigitalEarthAU USGS Landsat data, 1988-2018)

Our new paper has been published. We find water in the lake during the last glacial maximum with rapid drying after 19 ka sciencedirect.com/science/articl…

Talented colleagues @niwa_nz collected LIDAR data for our Lake Tennyson glacial history project with @GIShaun Prof Tim Barrows. Oblique aerial (top) has boulder locations and LIDAR model (below) exposes fine-scale topography. High-res terrain + moraines = targeting the right samples

Not long til GSNZ conference where we will present some @niwa_nz led glacial research at Lake Tennyson. Progress mapping landforms using LIDAR & chats w @GIShaun Prof Tim Barrows and Aaron Putnam. Part of the site shown here w a 25cm DEM, N aspect hillshade & 1M contour

Spectacular first field day for EESC250 field geology. Basalt dykes at Bombo quarry, Kiama with Lloyd White

Very windy day 2 of field trip at Port Kembla. Permian delta plain with lava flow and lava-sediment-water interactions. With Lloyd White

.@niwa_nz's Water Model is forecasting a rapid increase in river flows across Canterbury on Sunday 🌊 The heavy rain is likely to cause flooding & slips. Keep yourself up-to-date this weekend & follow the advice of emergency officials. 🟪 = extremely high flows

Wow check out the updated felt map! Felt reports coming in from Melbourne, Canberra, Sydney, Adelaide, Hobart, and Brisbane! earthquakes.ga.gov.au

Part of the remaining iceshelf left by the 2002 breakup of the Larsen B iceshelf has collapsed after continued warming of the region.

New U.S. National Ice Center-named icebergs resulting from complete collapse of East Antarctica's Conger Ice Shelf (~1200 sq. km) on/around March 15, seen in combo of #Landsat and #MODIS imagery. #CongerIceShelf #Antarctica @helenafricker Joanna Millstein

Ice surface speed measured from Copernicus EU #Sentinel1 appears to show that the Totten Glacier Ice Shelf in East Antarctica is heading for a calving event of 200 sq km or more (that's 1% of the size of Wales!)

PLEASE BE AWARE that there has been a large landslip at #Seatown, Dorset overnight. Dorset Council UK are aware. Be cautious and do not put yourself at risk. If you are in these areas, stay away from cliff edges and do not sit at the base of cliffs. 📸 James Loveridge Photography

In a paper published today in Scientific Reports, we used nearly 1,000 film photographs of Antarctica from the 1960s to reconstruct exactly what five glaciers were like decades before the Larsen B Ice Shelf collapse. theconversation.com/we-used-1-000-…
