Very fancy stereo camera system!
Great to the Voyis camera system attached to an ROV in action today. When attached to an ROV, this camera system helps build amazing 3D models of reef and structures. Very impressive technology in action!
The herbivorous, dark-purple coloured long-spined sea urchin, Centrostephanus rodgersii.
🧪🦤🌐
The herbivorous sea urchin Centrostephanus rodgersii removes macroalgae & creates barrens. Understanding density-dependent processes governing its abundance will assist with addressing the challenges it poses in some jurisdictions in south-eastern Australia.

Today we had the black cockatoos visit us. They come down from the mountains over winter to feed in coastal areas. They were living the proteas!
the galaxias hex logo showing a fun-coloured illustration of a green galaxias fish. The head, gills and fin in the centre with light green on the underside, green lips and wavy shades of green on its back, with blue and orange markings by its eye and gills. The background is light orangey-salmony colour in a sunburst style
🚨Our new package {galaxias} is released in R & Python today! 🚨
📦 galaxias makes it easy to standardise data to Darwin Core, the accepted format for sharing ecological data with infrastructures like @gbif.org and the Atlas of Living Australia

A thread 🧵👇
This study highlights the importance of long-term monitoring to be able to detect change, particularly in these highly remote and important areas. The JSDM approach is very powerful and provides information at the species assemblage level.

Most surprisingly, was the increase in species richness over the study period. The average number of species caught in a research trawl more than double over the two decades.
It is difficult to know what has driven this increase but it is likely a combination of the removal of IUU fishing, changes in fishing practices to reduce bycatch, the establishment of a marine reserve, and possibly climate-driven increases in ocean productivity.
We used a joint species distribution modelling, specifically HMSC, approach to model the entire demersal fish assemblage to provide new insights into how each species responds to climate, temperature, depth, marine reserve status.
Our latest research published in @GlobalChangeBio demonstrates how the demersal fish assemblage in the Heard Island and McDonald Islands (HIMI) region has vastly increased in occurrence, abundance, and species richness. over the past 2 decades.

Whoops… the importance of sea floor mapping!

A research team led by scientists from our University has returned from a major 54-day voyage on CSIRO research vessel (RV) Investigator to explore the impacts of the devastating 2022 eruption of Tonga's underwater Hunga Volcano.

On the tools! Piloting the ROV over some great mesophotic reef in the Commonwealth Solitary Islands Marine Park. We are doing 200m transects and some exploratory surveys.
Another day another round Of BRUV and ROV surveys in the Solitsry Islabds Marine Park! Dropped the BlueROV on some seriously awesome temperate mesophotic reefs! Black corals, octocorals, giant sponges! And of course some big fish!

Gumbaynggirr Rangers in action! BRUVing mesophotic reefs in the Solitary Islands Marine Park (Commonwealth) mapping fish and habitat.
We’re off to Coffs to survey the mesophotic reefs of the Solitary Islands Marine Park. This work is for an Our Marine Parks grant in partnership with Ngiyambandigay Wajaarr Aboriginal Corporation. Stay tuned for updates through the week!

Who remembers the Mathomat!! It’s been 30 years since this has been used but I need a protractor!!
Couldn’t agree more!
Last week I had the pleasure and honour to participate in a IUCN Red List workshop to assess Australia and New Zealand fishes! I learnt a lot through out the week. Including learning about this mesophotic only Bigeye Gurnard Perch!! Thanks everyone for a great week!

Once classified as extinct in the wild, these tiny marsupials are running free on three islands.
Technically, not extinct in the wild, there is a Tasmanian population. We have them living in our backyard!

Flashback to my 4th PhD chapter. While this was a classic 4th chapter, this goes down as one of my most interesting papers! Taking a multi-elemental approach to larval fish otolith microchemistry can distinguish location of larvae in the water column

New paper out! We found that a climate change-driven warming off Sydney has increased the amount of time bull sharks spend around Australia's biggest city. #sharks #climatechange #sydney #bullsharks

Haha thanks for sharing!
Congrats Matt! Super awesome effort! And well deserved!!
