Description

Dedicated to all things on Antarctica and the Southern Ocean, the Antarctic Report (https://www.antarcticreport.com) is an online portal published by Camino, a digital content and publishing company based in Auckland, New Zealand. The site showcases the hard science which underlines the importance of Antarctica as a bellwether of global climate change. It also highlights the continent's unique political status, as well as the exceptional demands its environment places on people and equipment, and the romantic allure for travellers and explorers as the least discovered continent on the planet.

The Antarctic Report was born out of the highly successful World Science Week, which brought together more than 2,000 of the world’s leading scientists, researchers and government science advisors for a series of international science summits in Auckland during August and September 2014. These major global gatherings included the 31st triennial General Assembly of the International Council for Science (ICSU) and the 6th biennial Open Science Conference of the Scientific Committee on Antarctic Research (SCAR).

Many of the scientists took part in a series of public lectures sponsored by the Royal Society of New Zealand and the Ministry of Business, Innovation and Employment, with the support of both the University of Auckland and AUT University where the presentations were held.

'Melting Ice, Rising Seas' was a presentation by five of the world's leading experts on the current state of the Antarctic Ice Sheet and surrounding Southern Ocean, how climate change is impacting upon them, and the consequences for Planet Earth as the 21st century progresses. (The video recording of the seminar presented here is the second of four).

Dr Stephen Rintoul is a physical oceanographer and climate scientist with a long-standing interest in the Southern Ocean and its role in the earth system. His research has contributed to a deeper appreciation of the influence of the Southern Ocean on global climate, biogeochemical cycles and biological productivity. He uses ships, satellites, floats and instrumented seals to explore the Southern Ocean and has led fourteen oceanographic expeditions to the Southern, Indian and Pacific Oceans. Dr Rintoul was a Coordinating Lead Author of the Oceans chapter in the 5th Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). His scientific achievements have been recognised by several national and international awards, including the Martha T. Muse Prize for Antarctic Science and Policy, the Australian Antarctic Medal and election as a Fellow of the Australian Academy of Science.

During his presentation, Rintoul explains the role ocean thermal expansion has to play in rising sea levels, the interaction between oceans and the Antarctic ice shelves, and how Antarctic Bottom Water is warming, freshening, and shrinking.
