The Autosub Under Ice (AUI) data set comprises hydrographic measurements including temperature, salinity, fluorescence, attenuance, dissolved oxygen concentrations and current velocities. Water samples were also collected for salinity and geochemical analysis, and the data set also includes bathymetric and sediment data. The measurements were collected near Greenland and Antarctica in the respective summer seasons for each hemisphere during 2003, 2004 and 2005. The programme consisted of four cruises onboard the ice-capable research vessel RRS James Clark Ross (JCR106, JCR106B, JCR84, JCR97). Data were collected by both shipboard sensors and those attached to the Autosub (an Autonomous Underwater Vehicle) package. Shipboard data collection included deployment of a conductivity-temperature-depth (CTD) package with attached auxiliary sensors. Lowered acoustic Dopper current profilers (LADCPs) were also attached to the CTD frame, while discrete water samples were collected from the CTD stations. Oceanographic, bathymetric and sediment data were collected along the ship's track, while further current data were collected from two mooring deployments. Autosub measurements included standard environmental parameters and acoustic instruments were used to measure ice shelf, sea ice and ocean bottom relief at high resolution. A camera was also attached to the vehicle, permitting the collection of detailed photographs of the seabed. Autosub had been upgraded to achieve 1000 km range and 2500 m water depth, which provided unprecedented access to ice covered regions. The AUI programme was established to investigate the marine environment of floating ice shelves with a view to advancing our understanding of their role in the climate system. It brought together researchers and engineers from a number of UK institutions, with the project being coordinated by the National Oceanography Centre, Southampton.

Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | This dataset was created by the organisations with the "originator" role in this metadata record following their in-house data processing and quality control procedures. The data were then provided to the British Oceanographic Data Centre (BODC) for ingestion into one of the schemas of the National Oceanographic Database (NODB). During ingestion BODC undertake quality control, documentation and metadata enhancement procedures appropriate to the type of data. For an overview please see http://www.bodc.ac.uk/about/information_technology/data_processing_steps/. BODC supply full information about data collection, data processing and data quality with all data requests to enable users to assess data suitability themselves. Instrument(s) used to collect data: bathythermographs; multi-beam echosounders; underwater cameras; benthos samplers; discrete water samplers; salinity sensor; >2000 Hz top-bandwidth sub-bottom penetrator and mud profiler systems; CTD; current profilers; snow and ice samplers. |
