Honours/Masters or PhD Student Opportunity part of the @OceanRes_UNSW Lab. Fishing for Ocean Data in Sea Country with Marine Rangers of the Tiwi Islands, NT. More details below.
We know that surface temps can mis-represent sub surface marine heatwaves. That’s why we are worming tirelessly to measure sub- surface ocean temperatures using fishing vessels.
To keep pace with a changing climate, and the expected increase in extreme events, we need to include freshwater discharge in our model simulations, and ensure our observe networks don’t neglect coastal salinity.
What does it all mean? With an increase in extreme rainfall expected in the future, we need to pay more attention to freshwater discharge in normally ‘dry’ areas such as eastern Australia.
Gliders showed extreme low salinity waters extended more than 70km offshore and persisted for months. We observed a vertical double-stacking phenomena with two layers of fresher water extending deeper than 50m. Stratification was controlled by salinity rather than temperature.
It turns out it hangs around for a surprisingly long time.
We used a combination of moorings, gliders and remote sensing to define an observational extremes framework for salinity. This allowed us to track the extent and longevity of freshwater plumes associated with floodwaters
What happens when a historic year of rainfall dumps a bunch of freshwater into the ocean next to a western boundary current?
In @NatureComms today, @moninya, @mphemming, Tim Ingleton and I look at the impact of the 2022 East Australian floods on the ocean

I recently spent 25 days aboard @CSIRO#RVInvestigator, chasing eddies in the East Australian Current system (i.e., my favourite ocean current). These were some of the best weeks of my life. A 🧵…
We were a diverse team of physical oceanographers, biogeochemists, atmospheric scientists and ecologists studying mesoscale eddy-eddy interactions. With 83 CTDs, 105 XBTs, 24 drifters, 24 radiosondes, 10,000+ seabirds, and 2850 nm travelled, we had a *very* productive voyage!
