Brief description

Metadata record for data from ASAC Project 1310
See the link below for public details on this project.

---- Public Summary from Project ----
Increasing UV-radiation over Antarctica each spring may damage DNA in plants. This research determined the susceptibility of Antarctic plants to such damage and investigated the effectiveness of protective and repair mechanisms. This helps predict how plants globally will cope with future climate change.

Samples have been collected from Heard Island, and near Casey Station, Antarctica. Three excel files constitute this dataset.

Heard Island 2003/4 Samples collected for project 1310

Vascular plant UVB site

GPS coordinates of vascular plant UV site 53 06 57 S, 73 43 30E A total of 4 g of each of 5 species (Pringlea antiscorbutica, Poa cookii. Deschampsia antarctica. Azorella selago, Acaena magellanica) were collected on 5 days over the season. These were analysed for DNA damage, UVB absorbing pigments, and photosynthetic and photoprotective pigments. Chlorophyll fluorescence and leaf temperature were measured on the sampled plants.

Nutrient gradient

GPS co-ordinates: high nutrient site: 53 06 0.419S, 73 43 0.105E 4g of P. antiscorbutica and 0.8g of P. cookii were taken at the high nutrient site, along with chlorophyll fluorescence measurements.

GPS co-ordinates: low nutrient site: 53 06 29.09S, 73 43 00.36E 7.2g of P. antiscorbutica and 3.2g of P. cookii were taken at the low nutrient site, along with chlorophyll fluorescence measurements.
