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.

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).

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.

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

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).

UNH Coastal Marine Laboratory. Ocean observation data from the Northeastern Regional Associationof Coastal & Ocean Observing Systems (Northeastern Regional Association Ocean Observing Systems (NERACOOS)).The NERACOOS region includes the northeast United States andCanadian Maritime provinces, as part of the United StatesIntegrated Ocean Observing System (IOOS). These data are servedby Unidatas Thematic Realtime Environmental Distributed Data Services (THREDDS) Data Server (TDS) in a variety of interoperabledata services and output formats

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).

NOAA CoastWatch distributes chlorophyll-a concentration data from NASA's Aqua Spacecraft. Measurements are gathered by the Moderate Resolution Imaging Spectroradiometer (MODIS) carried aboard the spacecraft. The algorithm currently used in processing the water leaving radiance to chlorophyll concentration has not yet been accepted as science quality. In addition, assumptions are made in the atmospheric correction in order to provide the data in a timely manner.

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).

NOAA CoastWatch distributes chlorophyll-a concentration data from the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) on the Orbview-2 satellite. Because the data was purchased under a NOAA contract with GeoEye, the data can be used but not redistributed. Images made from the data, however, can be used for any purpose. Questions regarding data access should be directed to NOAA CoastWatch.
