Acknowledgement of Traditional Owners I would like to pay respect to the traditional and original owners of this land, the Muwinina (mu wee nee nah) people, to pay respect to those that have passed before us and to acknowledge today’s Tasmanian Aboriginal community who are the custodians of this land.
CSIRO, Battery Point, Hobart Your Health and Safety are IMPORTANT Please remain within the public areas of the Auditorium, foyer and toilets (to the rear of these rooms), and the canteen If you wish to visit other CSIRO staff, please ask reception to contact the staff member on your behalf Smoking is not permitted in the buildings. There is an ashtray for smokers opposite the main entrance Please observe any safety signage In the event of an evacuation, a continuous alarm will sound, please gather together in the flagpole area (go out main entrance and turn right), or be instructed by the evacuation wardens (coloured hard hat) of an alternative gathering point An alternative evacuation route is through the Auditorium’s rear exit door Any questions regarding the site facilities – please ask at reception AUDITORIUM

CSHOR Highlights Explaining the large increase in ocean heat content in the southern hemisphere oceans A study based on previous Argo float deployments, published in Nature Climate Change (Gao, Rintoul et al., 2017), shows that wind-driven changes in formation and subduction of Subantarctic Mode Water in the Southern Ocean can explain the large increase in ocean heat content in the southern hemisphere oceans. 8 | CSHOR Science Seminar| Dr Wenju Cai
CSHOR Highlights Understanding the ultimate risk of extreme El Niño associated with a 1.5˚C warming target Figure 2c and 2d: Temporal evolution of multi-model ensemble mean changes under the RCP2.6 scenario Using five models with extended simulations to the 23rd century. The linear trends and their 90% confidence intervals over the 2050–2150 period and the 2151–2250 period indicate that although the GMT decreases, the meridional temperature gradient continues to weaken and the extreme El Niño frequency continues to increase before they reverse (Wang et al., 2017, Nature Climate Change). 9 | CSHOR Science Seminar| Dr Wenju Cai
CSHOR Highlights Understanding the ultimate risk of extreme pIOD associated with a 1.5˚C warming target In contrast to extreme El Nino, extreme pIOD frequency stabilises with global mean temperature, and during the transient period the frequency increases with the GMT (Cai et al. 2018). 10 | CSHOR Science Seminar| Dr Wenju Cai
CSHOR Highlights Changes in the Southern Ocean revealed by researchers aboard the RV Investigator Southern Ocean researchers aboard the RV Investigator find a shift in a decades-long trend towards fresher, less dense water off Antarctica. Dr Steve Rintoul, voyage chief scientist (image source: Peter Mathew 12/2017) Two Nature articles to appear soon. 11 | CSHOR Science Seminar| Dr Wenju Cai
CSHOR Highlights CSHOR won in the category of “Achievement in International Talents and Knowledge Introduction and International Collaboration” the only winner for the category and the only winner from Shandong province. The award was established in celebration of the 40th Anniversary of China’s Reform and Opening-Up Policy. The Chinese government established 40 awards in total.
