Antarctic snowfall exhibits substantial variability over a range of time scales, with consequent impacts on global sea level and the mass balance of the ice sheets. To assess how snowfall has affected the thickness of the ice sheets in Antarctica and to provide an extended perspective, we derived a 50-year time series of snowfall accumulation over the(More)
Antarctic Ice Sheet elevation changes, which are used to estimate changes in the mass of the interior regions, are caused by variations in the depth of the firn layer. We quantified the effects of temperature and accumulation variability on firn layer thickness by simulating the 1980-2004 Antarctic firn depth variability. For most of Antarctica, the(More)
In countries with liberalised alcohol policies, alcohol harm reduction strategies predominantly focus on young adults' excessive drinking harms and risks. However, research shows such risks are largely irrelevant for young adults, who emphasise the sociability, release, pleasure and fun of drinking. Friendship is a central part of their lives and an(More)
OBJECTIVES Understandings of health behaviors can be enriched by using innovative qualitative research designs. We illustrate this with a project that used multiple qualitative methods to explore the confluence of young adults' drinking behaviors and social networking practices in Aotearoa, New Zealand. METHOD Participants were 18-25 year old males and(More)
A range of negative health outcomes are associated with young adults' drinking practices. One key arena where images of, and interaction about, drinking practices occurs is social networking sites, particularly Facebook. This study investigated the ways in which young adults' talked about and understood their uses of Facebook within their drinking(More)
