Brief description

Geoscience Australia carried out a marine survey on Lord Howe Island shelf (NSW) in 2008 (SS06-2008) to map seabed bathymetry and characterise benthic environments through co-located sampling of surface sediments and infauna, rock coring, observation of benthic habitats using underwater towed video, and measurement of ocean tides and wave-generated currents. Sub-bottom profile data was also collected to map sediment thickness and shelf stratigraphy. Data and samples were acquired using the National Facility Research Vessel Southern Surveyor. Bathymetric data from this survey was merged with other pre-existing bathymetric data (including LADS) to generate a grid covering 1034 sq km. As part of a separate Geoscience Australia survey in 2007 (TAN0713), an oceanographic mooring was deployed on the northern edge of Lord Howe Island shelf. The mooring was recovered during the 2008 survey following a 6 month deployment. This folder contains the images derived from benthic samples taken on cruise SS06_2008 aboard Southern Surveyor. The main folder houses all images taken while processing samples at the microscope. These images formed the first point of reference in identifying subsequent specimens to save wear and tear on the specimens put aside as reference material. Three additonal folders exist within the main folder. Amphipoda contains repeats of the amphipod taxa, SS062008Biota contains images of live organisms taken as soon as the sample was recovered to the ship and Tanaidacea contains repeats of the tanaid taxa.

Statement: Images of fresh material were captured using a rostrum mounted Canon EOS 40D camera on the Southern Surveyor. Unique barcodes were incorporated into images to identify which sample an image corresponded to (see sample database for the SS06_2008 cruise or the SS06_2008 biological sample log book). Images of preserved material were made using a Nikon Coolpix camera mounted on a macroscope. The images were downloaded to the lab laptop and renamed according to the O T U assigned to the taxon it represented. Some notes were made on the images using Microsoft Paint, where prominent, taxonomically relevant features were available for highlighting. Image names were updated as identifications were refined.

Many taxon names were provided by Lauren Hughes and Jim Lowry at the Australian Museum. Tanzanapseudes was identified by Buz Wilson at the Australian Museum.
