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!

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.

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 👇

🌊 A group of marine scientists are embarking on a mission to restore the waters of the iconic Sydney Harbour.

If successful, it may become a template for revitalising other urban marine sites worldwide.

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

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 Nature Communications today, Prof Moninya Roughan, Michael Hemming, Tim Ingleton and I look at the impact of the 2022 East Australian floods on the ocean
