Samples were collected at ASPA 135, at the melt lake, northeast side during 2002/3 at Casey. Temperature sensors (i-buttons) were inserted into moss beds and a range of associated measurements were recorded (e.g. moisture and photosynthetic activity). The work was conducted by Jane Wasley and Johanna Turnbull over a two week period, from 15 to 28 January 2003. Other data in this collection include scanned copies of relevant pages from field (ibutton field notes 2002-3.pdf) and laboratory (ibutton lab notes 2002-3.pdf) notebooks. This collection is not available for public access.
