Abstract:
In the 2008/2009 season, samples of the bottom ice algae and brine algae (within 30cm of the top of the ice) were subjected to temperature, salinity, light and UVB experiments and analysed with PAM rapid light curves to determine the response of the algae to changes they will encounter. In the 2009/2010 season, samples of the bottom ice bacteria were subjected to changes in the colour of light in an incubation chamber. Samples were filtered and stored in liquid nitrogen for analysis in NZ.
Quality
Each parameter is assigned a data quality flag as defined below:
Flag 1: Error free Flag 2: Dubious. Non-specific errors Flag 3: Known errors exist that can be fixed Flag 4: Known errors exist that cannot be fixed Flag 5: No data - not observed ... Flag 6: Data in analog format only
