Presentations are the mainstay of academic life, as well as the corporate and business world. Undergraduate students will probably need to give solo or group presentations as part of their coursework. Postgradute students will certainly have to do so. But giving a good presentation is an art, and it takes a lot of practice. I thought in this blog post, I would share some of my tips and practical suggestions for giving a good presentation.

The top-down navigation structure of AntarcticGlaciers was becoming difficult to use due to the amount of content added to the site, necessitating numerous levels of nested drop-down menus. A top-down navigation scheme works well for up to say, 30 webpages, but once a website grows larger than that, it ceases to be user-friendly. Continue reading
A new paper by Levermann et al. in PNAS uses the record of past rates of sea level rise from palaeo archives and numerical computer models to understand how much sea level rise we can expect per degree of warming in the future. These data suggest that we can expect a global sea level rise of 2.3 m per 1°C of warming within the next 2000 years: well within societal timeframes. A 2°C of warming would result in a global sea level rise of 4.8 m within 2000 years. This would inundate many coastal cities in Europe alone, and cause untold economic and societal damage.
It’s one year almost exactly since AntarcticGlaciers went live at the start of July 2012. One year since I fumbled my way into this complex world of science communication. When I started out, I had little idea of what I was doing. I had never Tweeted (I viewed it rather as a waste of time), never made a website, and had never written for anyone other than academics and my peers. Continue reading
J.Boex, C. Fogwill, S. Harrison, N.F. Glasser, A. Hein, C. Schnabel and S. Xu. Rapid thinning of the Late Pleistocene Patagonian Ice Sheet followed migration of the Southern Westerlies. Scientific Reports 3: 2118, p. 1-6
The Patagonian Ice Sheet
This recent open-access paper in the new journal Science Communications, which is part of the Nature group, has demonstrated that the during the deglacial period (~19,000 years ago), the Patagonian Ice Sheet in South America responded rapidly in response to changing precipitation patterns and warming during the last deglaciation. The fact that the Patagonian Ice Sheet responded so quickly to changes in precipitation and temperature has vivid implications for the current, and future, behaviour of the current North Patagonian Icefield and South Patagonian Icefield. We already know that the shrinkage of the North and South Patagonian ice fields was faster over the last decade or so than at any point in the last couple of centuries. Understanding on a broader scale how these sensitive, high-latitude ice masses are dependent on small changes in atmospheric circulation means that we will better be able to predict the future behaviour of these ice sheets. Reconstructing rates of ice-sheet decay since the Last Glacial Maximum means that we can better assess the mechanisms of climate change (including changing wind patterns) during a major climate transition.

Do you consider yourself a science communicator? Does your research group participate in public outreach? Do you have creative ways to engage non-technical audiences in your research? Have you ever evaluated your education and outreach efforts? If so, we invite you to share with us during an informative session titled The Role of Scientists as Communicators: From the Classroom to the Pub (ED038) at the 2013 AGU Fall Meeting in December.

Many geoscientists undertake fieldwork as part of their research. Undergraduate, Masters and PhD students may all participate in fieldwork expeditions in far-flung, exotic locations. What things to researchers need to consider before they undertake their first expedition? I have put together this step by step guide, based on my 10 years of research in remote polar regions, to provide some tips and suggestions for a successful fieldwork expedition.
There is a movement afoot. Academics and scientists are entering the blogosphere, and their numbers are increasing 1,2. The majority are early career scientists – PhD students and post-docs, like me 3. I have already written about the benefits of blogging to early-career researchers, but here I explore blogging as an outreach tool in a little more depth. Continue reading
Using photographs in our research
As geoscientists, we are trained to observe and record the world around us. We often use but simple tools – a note book, a hammer, a camera, maybe a handheld GPS. With these implements, we can make careful observations and deductions about the evolution of the landscape around us. Continue reading
Sea ice and ice shelves
What is sea ice? Sea ice is frozen sea water; it perennially expands and contracts during each year’s winter and summer. Amongst the sea ice are icebergs calved from tidewater glaciers and ice shelves. Melting sea ice does not contribute directly to sea level rise (ice floats and displaces the same volume of water), but sea ice is important because it enhances climate warming. It changes the reflectivity of the sea water, reflecting lots of sunlight back (it has a high albedo), and is therefore an important component of the climate and cryospheric (icey) system.
