Full description

Cephalopods were sampled from a cyclonic cold-core eddy in the western Tasman Sea, using midwater trawls from 10th to 12th September 2017 during a research voyage on Australia's Marine National Facility RV Investigator. Two different types of trawl equipment were used. The first trawl type sampled the upper 100 m of the eddy using a Danish pelagic trawl with 300 μm mesh, towed at approximately 1 m/s (2 knots) for 60 min per trawl (n= 9). The second trawl type was an International Young Gadoid Pelagic Trawl (IYGPT) fitted with a MIDwater Open and Closing net system with six distinct codends to enable depth stratified sampling. The IYGPT trawl has a mesh size of 200 mm reducing to 10 mm, and the codend mesh size was 500 μm. The IYGPT trawl was lowered to 500 m, with the first codend sampling obliquely from the surface to 500 m, and each subsequent codend sampled 100 m depth intervals for approximately 20 min each at 1 m/s, as the trawl returned to the surface.
