ESRI grid showing the mean incident light for each quarter. This data is the surface solar irradiance data obtained for NASA/GISS to allow the prodction of photosynthetically active solar irradiance fields to allow the calculation of primary productio using satellite ocean colour products. The information comes from the Internation Satellite Cloud Climatology Project (ISCCP) using C1 data from multiple geostationary and polar orbiting meterological satellites to provide a global view of the occurrence and properties of clouds. Atmospheric, cloud and surface data from ICSSP are used as input along with a scheme for computing clear-sky irradiance from the solar zenith angle, air properties, and surface reflectance. The scheme then uses simple cloud properties (cloud fraction, cloud optical thickness, and diffuse albedo) to produce total and photosynthetically active solar irradiance fields (Bishop and Rossow 1991; ISCCP Documentation of Cloud Data; Frouin et al. 1989). Input and output data fields are given in a 2.5° latitude and longitude grid. These grids have been produced by CSIRO for the National Oceans Office, as part of an ongoing commitment to natural resource planning and management through the 'National Marine Bioregionalisation' project.

This record describes Photosynthetically Available Radiation (PAR) data collected as part of the 1991-1993 Tasmanian Slope Trophodynamics Study undertaken by CSIRO Division of Fisheries. PAR data were obtained from an irradiance sensor lowered through the water shortly after completing a CTD cast from which chlorophyll and productivity samples were taken, at a range of depths (surface to 1500 meters) on 4 cruises of FRV "Southern Surveyor" on three 60 km transects across the continental shelf to the south and south-east of Tasmania in July 1991 (cruise SS 02/91), February 1992 (cruise SS 01/92), November 1992 (cruise SS 04/92) and April 1993 (cruise SS 03/93).

Raw data from the Advanced Very High Resolution Radiometer (AVHRR) sensors on NOAA polar orbiting satellites, received at the Alice Springs station run by ACRES. These data are used later for computation of parameters such as sea surface temperature (SST). The data start from April 1986. The data provide complete coverage of continental Australia, from approx. 4000 satellite passes as at Oct. 1998. The data are stored on Exabyte tapes in Hobart.

Raw data from the Advanced Very High Resolution Radiometer (AVHRR) sensors on NOAA polar orbiting satellites, received at the Met Bureau's Darwin Satellite Reception Facility. These data are used later for computation of parameters such as sea surface temperature (SST). The data start from August 1992. The dataset contains approx. 4600 satellite passes as at Oct. 1998. The data are stored on Exabyte tapes in Hobart.

Monthly surveys of the continental shelf waters due west of Hillarys Marina (Perth, WA) were undertaken between October 1996 and December 1998, both to provide basic information on the water properties and as in situ validation of satellite SST and ocean colour data. Vertical temperature/salinity profiles were taken at each of the 9 stations across the 40-km transect, as well as depth-integrated nutrients and chlorophyll, light and optical properties, and phytoplankton and zooplankton samples. Surface temperature and fluorescence were recorded continuously across the transect.
