Research brief: Measuring spread in spatio-temporal changes of ocean heat content estimates

November 24, 2021 12:09 pm Published by Comments Off on Research brief: Measuring spread in spatio-temporal changes of ocean heat content estimates

90% of the heat trapped on Earth by anthropogenic greenhouse gasses is absorbed by the ocean, with the unfortunate by-product of thermosteric sea level rise - as the ocean warms, it expands. Therefore, it is essential that we can accurately measure how much heat the ocean is absorbing over time.

Research Brief: Seasonal and Interannual Variability of the Weddell Gyre

November 1, 2021 4:57 pm Published by Comments Off on Research Brief: Seasonal and Interannual Variability of the Weddell Gyre

The Weddell Gyre, located east of the Antarctic Peninsula, is one of the largest features of the ocean circulation of the Southern Hemisphere. A deeper understanding of the dynamics in this remote region will shed light on the role of the gyre in our present climate and help us understand its potential evolution with climate change.

Briefing note 17: Could understanding the Indian Ocean improve climate predictions for Australia?

You may have heard about the influence of sea surface temperatures (SSTs) in the tropical Pacific Ocean on Australia’s climate and how forecasts of the El Niño–Southern Oscillation (ENSO) help to give warnings of flood, drought and bushfire risk in Australia months in advance… but what about the tropical Indian Ocean?

Research brief: Ekman Streamfunction a strong indicator of overturning circulation strength & variability

October 7, 2021 2:30 pm Published by Comments Off on Research brief: Ekman Streamfunction a strong indicator of overturning circulation strength & variability

CLEX researchers used a state-of-the-art global ocean-sea-ice model to directly measure the overturning circulation, and through this to examine the relationship between the Ekman Streamfunction and the Southern Ocean overturning circulation.

Research brief: The path to a sustainable future using marine-based mitigation measures

September 27, 2021 1:55 pm Published by Comments Off on Research brief: The path to a sustainable future using marine-based mitigation measures

In this paper, as part of the Future Seas project, the researchers built upon previous work by using a foresighting scenario analysis technique to envision two alternative possible futures for society by 2030, in the context of the challenge of climate change adaptation and mitigation.

Australian bushfires spawn massive phytoplankton bloom

September 16, 2021 8:26 am Published by Comments Off on Australian bushfires spawn massive phytoplankton bloom

The Australian bushfires of the 2019/2020 summer had far-reaching effects. It has now been revealed in new research published in Nature that the smoke produced a phytoplankton bloom larger in area than all of Australia, thousands of kilometres away in the Southern Ocean between New Zealand and South America.

Research brief: How Arctic primary production will alter with climate change

September 8, 2021 4:42 pm Published by Comments Off on Research brief: How Arctic primary production will alter with climate change

Predicting how much primary production will further increase in the Arctic Ocean in coming decades depends on the interplay between the increase in light for primary producers, as the sea ice extent and thickness decrease, and the availability of food in the form of nutrients, such as nitrate, phosphate, and silica.

Research brief: Climate change to cost Pacific tuna fisheries millions

September 8, 2021 4:09 pm Published by Comments Off on Research brief: Climate change to cost Pacific tuna fisheries millions

Using model simulations of the movement of tuna distributions across the tropical Pacific subject to projected ocean changes, the researchers found that without strong mitigation efforts, tuna distributions are likely to shift away from island fishing zones.
