The first snowfall on the peaks of Snowdonia could be observed from my University building today, I have received the first ‘snow dump alerts’ for a number of alpine ski resorts (see Webcam link below) and televised ski competitions have kicked off for the 2012/13 season. These events inspire personal feelings of elation and excitement every year associated with snow and skiing. Imagine my delight when I discovered the keywords ‘ski’ and ‘geomorphology’ attributed to the same paper this week! These are applied to an Early View paper in Area by Voiculescu and Onaca examining the frequency and magnitude of snow avalanche risk over recent decades at the Sinaia ski resort, Romania, using dendrogeomorphological techniques.
Their approach employs high-precision visual examinations of tree rings in order to identify damage delivered by severe avalanches. The annual growth rings enable the specific year in which each avalanche occurred to be confirmed. They subsequently apply frequency statistics to these data to estimate return periods for the most hazardous snow avalanches. Using such historical data to improve avalanche risk estimation will be invaluable for developing mitigation strategies and preventing future disasters, considering the fatalities which occur due to avalanches each year.
There would be considerable value for this post to examine the techniques they use in greater detail, but I think there are more widespread implications also, of which this is one example. Many scientific blogs feature practising academics or other experts offering explanations of recent peer-reviewed research using terminology more accessible to any reader and a better understanding of complex analytical techniques by the public has widespread implications. A great number of people poorly understand science presented on such crucial topics as climate change and extreme events, for example, and this can be the result of either insufficient explanation or, more concerning, intentional misinterpretation.
The Leveson report, released on Thursday November 29th, 2012 and featured prominently in the recent news, repeatedly highlights false balance in media reporting on GM crops and climate change, for example. Blogs, by definition, are an avenue for personal opinion to be put forward; nevertheless, they offer opportunities for the public to easily access expert knowledge on highly relevant topics. As a result, provided science blogs ensure the professional qualifications and experience of contributors can be easily verified by readers, blogs will become an increasingly important method for effective communication of complex science relevant to the public.
