BODC Data Processing

Data Processing

The data arrived at BODC as individual .mat files containing data collected on moorings OP1, OP2, OP5 and OP7. They were submitted as part of an accession including several different instruments - ADCP, Aquadopp, RCM11, SBE37 and SBE39.

Reformatting

Due to the file size it was decided that the data would be sub-sampled to a one minute interval. The original files (with 10s sampling interval) are available upon request.

Parameters in the originator's files were reformatted into an internal file format using BODC standard procedures.

Some variables included in the RBR files have not been reformatted into the internal format files, as they will be stored as metadata. These include - botdepth (meters), date, lat (degrees north), lon (degrees east), mooringname, nomdepth (meters), serial_no and type.

The following table lists all the parameters included in the internal format files, showing how the originator's variables as named in the matlab files were mapped to appropriate BODC parameter codes.

Screening

Quality control flags were automatically added to data outside the expected parameter specific range during the reformatting process. All parameters were then visualised and screened using in house software, and any improbable or missing data point was assigned a quality control flag.

Sampling Strategy

Sampling was carried out as a part of the 'Dynamics of the Orkney Passage Outflow (DynOPO)' project. The project involved the deployment of several instruments in the Orkney Passage in the Southern Ocean's Weddell Sea.

The instruments were deployed during cruise JR20150309 (JR272D, JR310) between 09 March 2015 — 14 April 2015. Moorings M2, M3a, OP1, OP2, OP3, OP4, OP5, OP6 and OP7 were recovered as part of cruise JR16005 between 17 March 2017 — 08 May 2017. In total, 45 RBR instruments were deployed on moorings OP1, OP2, OP5 and OP7.

The pressure data included in the originator's files was inferred from other nearby instruments with pressure sensors.


Project Information

Dynamics of Orkney Passage Outflow (DynOPO)

DynOPO is a five year research project that aims to understand how Antarctic Bottom Water is exported and modified through the Orkney Passage, the overflow's controlling dynamics, and its downstream impact on the Atlantic Ocean abyss.

Introduction

Mooring data collected for the DynOPO project are a component of a long term time series, in association with the Ocean Regulation of Climate by Heat and Carbon Sequestration and Transports (ORCHESTRA) project, led by Emily Shuckburgh (British Antarctic Survey) since 2016. The time series originally started out as part of the British Antarctic Survey's Long-Term Monitoring and Survey (LTMS) programme. Moorings were deployed on RRS James Clark Ross cruise JR20150309 (JR310 and JR272D) which ran from 09 March to 14 April 2015. RRS James Clark Ross cruise JR16005 ran from 17 March to 08 May 2017 and was the primary fieldwork element of the DynOPO project. The cruise had two main goals: (1) to conduct measurements of the hydrographic properties, velocity and turbulent processes of the Antarctic Bottom Water outflow along its pathway through the Orkney Passage region; and (2) to turn around a set of long-term moorings deployed in the area by British Antarctic Survey (BAS) and Lamont-Doherty Earth Observatory (LDEO) scientists, including recovery of additional instruments on some of the moorings deployed by JR20150309.

Project Collaborators

The project was led by the University of Southampton, and is an international collaboration with;

  • UK: British Antarctic Survey (BAS), UK Meteorological Office, University of East Anglia and Newcastle University;
  • Europe: University of Gothenburg (Sweden), University of Paris 6 (France);
  • Australia: University of Tasmania;
  • US: Lamont Doherty Earth Observatory, Woods Hole Oceanographic Institute, NOAA, University of California, Washington State University and Princeton University

Funding

The project was funded by the Natural Environment Research Council and ran from March 2015 to November 2018.
