The individual aims and objectives of each cruise can be found in their cruise reports. The specimens have been collated into a single dataset, forming the basis of J Maxwell’s PhD. The dataset will be used to investigate the community structure of Antarctic pycnogonids and the factors which influence its composition.","EngDescr":"The samples were collected from different areas in the Southern Ocean, mainly the Weddell sea, South Orkney Islands, and the Western Antarctic Peninsula.\r\n
\r\nPycnogonida were identified to at least genus or species.\r\n
\r\nThe majority of the specimens were sampled using an Agassiz trawl (AGT) and an epibenthic sledge (EBS) with 165 AGT and 14 EBS deployments. The AGT had a mesh size of 1 cm and a mouth width of 2 m (except for JR17007 where the mouth was 1.25 m). AGTs were deployed to a depth of between 54 and 2279 m. The EBS had a suprabenthic- and an epibenthic net, both with a mesh size of 500 μm (cod-ends 300 μm). The epibenthic net extended from 27 cm to 60 cm above the bottom, with the suprabenthic net extending from 100 cm to 133 cm. The EBS was deployed as described by Brenke (2005) and was fitted with an open-closing mechanism so that the mouth of both nets were closed whenever the EBS was not in contact with the seafloor. EBSs were deployed to depths of between 436 and 5339 m. Both the AGT and EBS were deployed for approximately 10 minutes (trawling time) and at a speed of 1 knot. Pycnogonids were also recovered from Rauschert dredge (RD) deployments, once during PS118 and two occasions during both JR15005 and PS77. During PS118 and PS77 the RD mesh size was 1 mm, while a mesh of 500 μm was used on JR15005. The RD was deployed attached to the AGT with 5 metres of cable. Deployments were between 278.5 – 817 m. A bottom trawl was used during PS77, which was a 130ft trawl with a 10 mm herring codend. This was deployed 12 times at depths of between 223.5 and 486 m. The protocol for deployment of the BT was similar to that of the AGT but with slightly longer trawl times (approx 20 min). A single pycnogonid was recovered from a kelp raft that was recovered from the surface during JR15005.\r\n
