Progress on the shelf is slowed considerably by large numbers of boats and gear anchored at night limited transect lines to daytime only.
To date we have completed 42 tows and caught over 80 species from a total catch of almost 2300 kg. Almost one third of the total came from a single tow.
The 17 offshore oceanographic stations (CTD, multinet and phytoplankton tows) are complete, along with the shrinking of many decorated polystrene cups that were attached to the CTD.
The diurnally-migrating mesopelagic layer has covered almost all of the offshore region, with higher densities to the west, particularily on the shelf break. The dominant species has been Benthosema fibulatum with small numbers of other species. We also caught one species that was not previously recorded from this area.
We have also carried out multi-beam work on two seamounts on the Murray Ridge. There was very little biological backscatter from above the seamounts, perhaps due to the very low concentrations of dissolved oxygen in the surrounding waters. Interestingly, we did note an increased density of flying fish while above the seamounts.
