.@curt_champ combining #citizenscience data and #remotesensing to model exactly how long Yellowtail Kingfish will be hanging around your neighbourhood with #climatechange! 🐟 (my home town of Forster representing at #AMSA18!

.@ReneCampbellArt setting an entirely new standard for beautiful and informative scientific posters at #AMSA18! #dataviz #datavisualisation

Challenging ideas from @AlistairHobday at #AMSA18: efforts to help species adapt to climate change can be surprisingly effective + affordable (e.g. building artificial Shy Albatross nests). But will this preserve genes that will doom species in the long run? #Genomics may help!

.@Marine_Lechene testing if #photogrammetry and large area photo mosaics can fill the gap between low-res #remotesensing and high-res field sampling for marine habitat mapping #AMSA18

Fascinating talk by @AurichtHannah at #AMSA18, using #MODIS #remotesensing to show that Murray-Darling outflows affect primary productivity up to 60km from the river mouth & declining river flows during #MilleniumDrought strongly reduced productivity. What will #climatechange do?

Nick Murray @remotelysense from @CES_UNSW presenting #machinelearning-derived maps of the global #intertidal zone over time powered by @GoogleEarth Engine #AMSA18

Finally, as a special #AMSA18 sneak-peak: we're currently working on another new product produced using the #DigitalEarthAU archive and tidally tagged imagery: a National Intertidal Digital Elevation Model (#NIDEM) for Australia's entire coastline! Watch this space...

By creating composites for the mid-tide range for areas of possible coastal change, we can effectively isolate the effect of tide, and produce noise-free "filmstrip" plots of the coastline as it evolves over time #DigitalEarthAU #AMSA18

Using new #geomedian compositing methods developed by @Dale_Roberts, we extracted the single most "representative" observation for each pixel across the past 30 years for a subset of tide heights #AMSA18

#DigitalEarthAU at @GeoscienceAus manages a continental archive of 30 years of analysis-ready/#ARD #EarthObservation data. Every observation is calibrated so images can be compared consistently across time and space #AMSA18

Live-tweeting my #AMSA18 talk! #RemoteSensing is an amazing tool for studying coastal change, but traditionally most analyses have compared change using individual hand-selected time-steps. Here, I explore a new approach based on the full 30-year #DigitalEarthAU #Landsat archive

Still signing copies of #TheEffectiveScientist at the @TheCoopAu table in Hall E @AMSAconf #AMSA18 Please drop by & say hello

We also can't underestimate the cultural impact of climate-driven range shifts: how do #indigenous communities respond when new species without traditional songs move in? #AMSA18

Only a tiny fraction of governments with fast-warming oceans have formal plans to deal with shifting species. Informal adaptions *are* happening locally and in industry, but these actions can directly conflict with government objectives #AMSA18

Come along to the @flinders @TheCoopAu table today @AMSAconf to get a discounted copy of #TheEffectiveScientist. I'll be signing copies from 12:30-14:00 #AMSA18 #booksigning @CambridgeUP

Come see my talk at 16:30 today in E1 'Predicting sustainable #shark harvests when stock assessments are lacking' #AMSA18 @taaprowse @BronGillanders @DonnellanSteve @HuveneersSSEG @SouthernSharkEG @AMSAconf

Fascinating keynote by @GrettaPecl at #AMSA18 on #climate-driven species redistributions: some species are far more "shifty" than others, but we also need to account for an ecosystem's "receptiveness" to new migrants - shifting species can affect ecosystems as much as invasives!

Do you like #satellites and the #coastal zone? If so, drop in to my #AMSA18 talk at 2.15pm in E3 (listed under "Sagar"), where I discuss how #EarthObservation data and tidal modelling can be combined to reveal coastal change! #DigitalEarthAU

Robin Beaman presenting the incredibly impressive 3D-GBR 30m resolution DEM of the entire #GreatBarrierReef, made by combining over six different data sources including #DigitalEarthAU 's Intertidal Extents Model! #AMSA18

New higher resolution maps can give new insights into the features and processes that shape the ocean's floor. Rachel Nanson from @GeoscienceAus presents a new genetic seafloor feature classification, and some beautiful #dataviz! #AMSA18

Iain Parnum: multibeam acoustic seafloor backscatter can be used to map hard and soft substrates like and gravel, and identify marine fauna in the water column! ("fish-like targets"? 🔊 ... 🐟) #AMSA18

Kevin Mackay at #AMSA18: we have huge gaps in seabed mapping: over 82% of global #bathymetry is interpolated! The @seabed2030 project aims to map 100% of the seabed by 2030 at resolutions from 100m to 800m

Tanya Whiteway from @GeoscienceAus at #AMSA18: only a fraction of Australia's seabed is mapped in high resolution... to improve this, we need a plan! Enter #AusSeabed: a national seabed mapping coordination program based on free and #OpenData

Dr Gary Greene taking #AMSA18 through the evolving science of submerged canyon formation... from beautiful orthographic diagrams to the latest in multibeam #bathymetry! @AMSAconf

I'll be presenting our paper on 'Predicting sustainable shark harvests when stock assessments are lacking' @AMSAconf on Tuesday 3 July at 16:30 in Room E1 #AMSA18

Attending @AMSAconf this week in #Adelaide? I'll be doing a book signing for #TheEffectiveScientist at lunchtime on Tuesday (3 July). You can get a 20% discount on paperback purchases if you drop by #AMSA18 http://www.cambridge.org/9781316620854

Excited to be travelling to #AMSA18 in #Adelaide to present on all the ways petabyte archives of analysis-ready #satellite data can be used to detect + characterise coastal change! #DigitalEarthAU 🌊🛰️
