How do you study change in a place as dynamic as the Australian coastline? Stephen Sagar from @GeoscienceAus shows how the #DigitalEarthAU @USGSLandsat archive be used to study 30 years of coastal change, including coastal erosion and mangrove expansion/dieback #ECSA57

Why did mangroves die off suddenly across huge areas of northern Australia in 2016? @EmmaAsbridge used #satellite data, #LIDAR, #drones and aerial photos to investigate, with results pointing to a temporary drop in sea level and changes in river discharge #ECSA57

Sea grass beds in South Korea survived some typhoons but were wiped out by others...why? Kim et al. used 26 years of #remotesensing data from multiple satellites to reveal that the most damage occurs when typhoons hit the coast at the same time as extreme low tide! #ECSA57 🛰️🌀

Combining trophic flows, contaminants biomagnification and isotopic mixing through ecosystems : @jeremail2011 presents @escropath during #ECSA57. #mixSIAR #ecopath @Irstea_Bordeaux @DrouineauH

.@rimu_tim from @csiro showing how @OpenDataCube can make it exponentially easier to access calibrated + processed #satellite data and study surface water quality at continental scale! #ECSA57 🛰️💧

A new national #mangrove dataset for Australia! Aero Leplastrier from @GeoscienceAus showing #ECSA57 how 30 years of #remotesensing data can be used to map the distribution + structure of mangroves across time, and study the impact of extreme events like cyclones 🛰️🌳🌀

Aero Leplastrier from @GeoscienceAus: the Topographical Position Index can be applied to sea surface temperature data from the high temporal frequency #Himawari8 satellite to amplify and map the signal of oceanographic upwelling! #EarthObservation #ECSA57 🛰️🌊🌡️

.@GrettaPecl starting off Day 2 at #ECSA57: species movements due to #climatechange aren't theoretical: 25-80% of species are already moving, and moving fast!

Very relevant to #ECSA57! How satellite imagery can be used to study and map the coast at low and high tide, and then isolate tidal effects to monitor coastal change across time! #DigitalEarthAU

If you're interested in how satellites 🛰️ and tide modelling 🌊 can be used to map the coastal #intertidal zone (in #3D!), drop by to my poster at #ECSA57! #DigitalEarthAU

Charitha Pattiaratchi at #ECSA57: to understand sea level rise, we need to understand #tides... and they're complicated! Both lunar cycles and interannual variability driven by ocean currents and El Niño–SO can exceed and interact with sea level change caused by #climatechange

Excited to be in Perth for #ECSA57, and off to an appropriate start: planning out new #intertidal + #remotesensing science inspired by some of the spectacular coastal landscapes below! 🌊🛰️
