A blog post I wrote for CSIRO about my PhD research and new paper on whale shark movements 😀.

Female whale sharks are conspicuous in their absence from aggregation sites such as Ningaloo Reef. A unique satellite tracking data set is showing us where they are so that we can begin to understand...

There was some evidence that females preferred cooler waters than males, particularly in Spring months. On average, females also appeared to dive deeper in warmer temperatures (>26°C) relative to males.

Female whale sharks migrated from Ningaloo Reef earlier in June/July and spent more time offshore, while males stayed longer and used coastal waters more frequently.

NEW RESEARCH - Proud to finally share my first lead-author paper on Whale Shark movements! 🐋🦈 We found sex-specific differences that improve our understanding about movements by females 🌏🔭 Link to read @CSIRO @UTAS_ #NingalooOutlook

The discovery that lumps of metal on the seafloor produce oxygen raises questions over plans to mine the deep ocean.

Nature is crazy!.
‼️TW: Graphic Imagery ‼️. Stole this vid of an orca predating on a whale shark off of fb 🔗👇. They are displaying v similar behaviour to Port and Starboard, but in the Sea of Cortez. It seems the first orca is distracting the WS while the second removes the liver! Fascinating.

Great to be a part of the field work in the beautiful Abrolhos Islands for this project with @minderoo & @CSIRO !.
Tiny cell fragments are being collected off WA's coast to create a 'DNA library' of Australian animals. @SarahSmith9_ #9News

Great to see some of my footage from a recent field trip used in this video!.
We're building a huge DNA library of Australian plants and animals! 🧬 📚 . This will help make identifying (and protecting) species much easier. We can use simple eDNA methods to monitor biodiversity in an area. @minderoo .

Latest on the CSIRO blog - here's an update on the Ningaloo Outlook projects that myself and my fellow PhD scholars are working on! Six months in and still in the honeymoon phase :) #phdlife #ningalooreef.
