Abstract
The files in this dataset contains raw datafiles from a NORTEK Signature rig. The rig was deployed in a fixed position just north of the South Orkney Islands in the Southern Ocean. The data is from a Signature 100 instrument, this instrument combines a 4 beam acoustic doppler current profiler with a vertically oriented echosounder (5.th beam, upwards looking). Information on instrument settings used etc. can be found in the binary files (NORTEK proprietary ad2cp format). For extraction of echosounder data we recommend NORTEK software, but these files are also readable using for instance the software packages of the IMOS toolbox (https://help.aodn.org.au/aodn-data-tools/imos-toolbox/). The current meter data in the files are also readable using the “oce” package (https://github.com/dankelley/oce) available under the software environment “R” ( R Core Team (2020). R: A language and environment for statistical computing. R Foundation for Statistical Computing, Vienna, Austria. URL https://www.R-project.org/.) The purpose of all this deployments was to study krill behaviour and the advective environment in a “krill hotspot”, an area with high importance to krill predators, both natural and human, as part of the NFR funded “SWARM” project (RCN 267416 “From swarming behaviour to trophic interactions: forecasting dynamics of Antarctic krill in ecosystem hotspots using behaviour-based models”).
