The International Glaciological Society [IGS] will hold its fourth sea ice symposium in Hobart, Tasmania, from 10-14 March 2014. Registration is now open for the symposium on "Sea Ice in a Changing Climate". The symposium aims to assess the current state of the marine cryosphere, which is one of the fastest responders to climate change and variability in both hemispheres. The conference will embrace multiple aspects of sea ice science, including cryospheric physics and climate, ice-ocean-atmosphere interactions, biogeochemistry, ecosystems research, policy, logistics and science communication. The symposium will be sponsored by the Antarctic Climate and Ecosystems CRC. It will feature eight keynote speakers within four-and-a-half days of scientific presentations, including lightning e-poster sessions. Social functions will include a reception hosted by His Excellency the Governor of Tasmania. Several satellite meetings and workshops will also take place before (8-9 March 2014) and after (15-19 March 2014) the symposium, including the International Antarctic Buoy Programme (IPAB) participants’ meeting, the Antarctic Sea-ice Processes and Climate (ASPeCt) workshop, and a three-day workshop on SIPEX 2012. Details on those can be found at the symposium's webpage. Abstract submission will remain open until 30 August 2013, and submissions to the thematic issue of the Annals of Glaciology are welcome until 20 December 2013. Both are through the IGS WWW page (http://www.igsoc.org/symposia/2014/hobart/). A public science day, with presentations and experiments by, and interactions with, local and international conference delegates will be held on 9 March 2014. The audience will include school groups as well as the general public. See the conference website (http://seaice.wwwace.aappartnership.org.au/igs2014/) for further details on the symposium, including session topics, timelines, and travel information.
