This dataset contains chlorophyll a data collected by the Aurora Australis on Voyage 6, 1997-1998 - the SAZ (Subantarctic Zone) cruise. Samples were collected in March of 1998. These data were collected as part of ASAC project 40 (The role of antarctic marine protists in trophodynamics and global change and the impact of UV-B on these organisms).

This dataset contains chlorophyll a data collected by the Aurora Australis on Voyage 2, 1997-1998 - the ONICE cruise. Samples were collected from September-November of 1997. These data were collected as part of ASAC project 40 (The role of antarctic marine protists in trophodynamics and global change and the impact of UV-B on these organisms).

This dataset contains chlorophyll a data collected by the Aurora Australis on Voyage 7 1992-93, taken in the Prydz Bay region between January and February 1993. These data were collected as part of ASAC project 40 (The role of antarctic marine protists in trophodynamics and global change and the impact of UV-B on these organisms).

Chloropyll a data were collected on voyage 4 of the Aurora Australis, during the 1991-1992 season. These data were collected as part of ASAC project 40 (ASAC_40) (The role of antarctic marine protists in trophodynamics and global change and the impact of UV-B on these organisms).

Chlorophyll a data collected on the CLIVAR (Climate Variability) cruise of the Aurora Australis in the 2001-2002 season. Data were collected from October to December of 2001 along the CLIVAR transect. These data were collected as part of ASAC project 40 (ASAC_40) - The role of antarctic marine protists in trophodynamics and global change and the impact of UV-B on these organisms.

Chloropyll a data were collected along the WOCE transect on voyage 1 of the Aurora Australis, during October of 1991. These data were collected as part of ASAC project 40 (The role of antarctic marine protists in trophodynamics and global change and the impact of UV-B on these organisms).

Chlorophyll a data collected on the AAMBER II cruise of the Aurora Australis from January to March of 1991. The voyage traveled to the Prydz Bay region, and data were collected en route and in the area.

Chlorophyll data was used to measure growth rates of sea ice algae in CO2 incubations. Sea ice brine microalgae was collected from sackholes. Replicate samples were incubated in ambient air (~0.04% CO2), 0.1% CO2, 1.0% CO2 and 2.0% CO2 concentrations. AT the end of the incubations the 50 ml samples were filtered through a 25 mm GF/F filter using vacuum filtration. The filters were placed in 15 ml plastic falcon tubes containing 10 ml of methanol, covered in aluminium foil and kept in the dark at 4 degrees C for 12 hours. Chl a concentration was measured using a 10AU Turner fluorometer following the acidification method of Strickland and Parsons (1972). Data in spread sheet shows the extracted chl + phaeophytin, phaeophytin and chlorophyll concentrations (micro grams l-1) for each of the three experiments. Data were collected at SIPEX Ice Stations 1-8 and SIPEX CTD stations 2-5

This dataset contains the underway data from Voyage 1 1992-93 (MONGREL) of the Aurora Australis. This voyage visited Mawson and Davis, leaving from and returning to Hobart. For further information, see the Marine Science Support via the Related URL section.

This dataset contains the underway data from Voyage 4 1994-95 (WOCET) of the Aurora Australis. This was a manned marine science cruise. DLS and NoQalms data types were logged at 10-second intervals. CTD and XBT data were also obtained on a run from Hobart to the ice edge along the WOCE SR3 line, then to Casey, and back to Hobart, between December 1994 and February 1995.
