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

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.

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.

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.

We love lists! Watch out for this one Australia’s hottest 100 scientists.

Explore marine heatwave and cold spell characteristics since the 1940s/50s in Australian coastal waters with our latest data products! 🌊📊 Data description paper: twtr.to/kuHIf with Prof Moninya Roughan Dr Amandine Schaeffer #oceandata #fairdata #marineheatwaves #oceanextremes

Prof Moninya Roughan Dr Amandine Schaeffer Using daily temperature climatologies and a widely-adopted definition, we detect marine heatwaves and cold spells, heat spikes, and cold spikes since the 1940/50s. We provide event characteristics and a handy event index variable for selecting specific event types 👇

Excited to announce #SeaCofs The coastal ocean forecast system for SE Australia in collaboration with @ACCESS_NRI Integrated Marine Observing System @SydneyMarine UNSWOceanography and UNSW Science UNSW Biological, Earth and Environmental Sciences

📣📣UNSWOceanography are hiring a project officer.📣📣 Are you highly organised, what to make a difference? Passionate about the #ocean? Want to live in #Sydney. @unsw is a great employer. Position closes 21 April. external-careers.jobs.unsw.edu.au/cw/en/job/5237… Pls retweet.

It's been a rather rainy week here in Sydney, it felt a lot like the record rains of 2022. So I plotted up the data and wow! This week has been an almost perfect match with April 2022. However, in 2022 we had already received an entire year's worth of rainfall by this stage.

You can see the effect of an increase in the amount of freshwater flowing into the ocean in this ocean colour image from Integrated Marine Observing System oceancurrent (red patches along the coast next to rivers and estuaries). Note how the plumes flow north due to Coriolis!

IMOS congratulates the Bluelink Global Ocean Science Team at Bureau of Meteorology, Australia CSIRO for winning a Australian Museum Eureka Prizes. 👏 IMOS data from Argo floats, ships of opportunity, ocean radars, gliders & satellite products contribute to the Bluelink ocean forecasts. #NCRISImpact
