This data set contains Simrad EK500 single beam echosounder data at 38 and 120 kHz and Simrad EA500 single beam echosounder data at 12 kHz from the Southern Surveyor. The EK500 data is primarily for water column characterisation (fish stocks, microplankton distribution) and on occasions for seabed classification (particularly prior to the EM300 swath mapper being installed), while the EA500 data is primarily for bathymetric readings.

This dataset contains the Underway (UWY) data collected on Naturaliste NA200410. The voyage took place off Southwestern Western Australia during 15th - 18th Dec 2004. This dataset has been processed and is archived within the CSIRO Marine and Atmospheric Research Data Centre in Floreat.

The data were collected at 5 stations on the RV Southern Surveyor SS 01/2004 voyage in January 2004. The data were collected to determine the bio-optical charateristics of this region. The data can be used for Ocean Colour sensor validation. Parameters measured absorption coefficients of phytoplankton phytoplankton (aph) and non-algal or detrital matter (ad) in discrete sea-water samples, determined using a laboratory spectrophotometer. Also concentration of chlorophyll and carotenoid pigments were measured by High Performance Liquid Chromatography of pigments in discrete sea-water samples using the method of Van Heukelmen and Thomas 2001. This data was part of Strategic Research Fund for the Marine Environment (SRFME) project where samples were collected from Two Rocks offshore transect from coastal to offshore stations at five sites (A-E) during (Feb 2002 - Dec 2004). These sites were also sampled during Southern Surveyor Voyages SS07/2003, SS01/2004. Note sites A and B were the same locations from the Two Rocks coastal transect identified as T1 and T6 respectively in Marlin record 6819 SRFME Ocean Colour data. Microphytobenthos samples were collected at sites where Martin Lourey worked. Note that this record contains data for Voyage SS01/2004 only.

These sites were also sampled during Southern Surveyor Voyages SS07/2003, SS01/2004. The samples were analysed for total suspended matter, absorption coefficients for dissolved and particulate matter and pigment concentration and composition.
