Orkney Passage OP2 mooring Data Quality Report

Screening and Quality Control

During screening procedures it became apparent that data logging did not occur as expected. Several gaps were identified in one instrument in this mooring.

It was confirmed that these issues were also present in the raw files, excluding the possibility of a data processing issue. Given that it is not clear which timestamp was recorded correctly, it was decided to remove the duplicate times from the final file.

Anomalous data values were also flagged M. See below for more detailed information of affected periods:

Narrative Documents

Aanderaa Recording Current Meter Model 9/11

The RCM 9/11 is a family of single-point Doppler recording current meters with different casing options to allow working at depths of up to 300 (RCM 9 LW), 2000 (RCM 9 IW) or 6000 (RCM 11) metres. The recording unit is 51.3 cm or 59.5 cm high (RCM 9 and RCM 11, respectively) with a diameter of 12.8 cm.

The RCM is most commonly deployed in an in-line mooring configuration. As it operates under a tilt up to 35° from vertical, it has a variety of in-line mooring applications by use of surface buoy or sub surface buoy. The instrument is installed in a mooring frame that allows easy installation and removal of the instrument without disassembly of the mooring line. The instrument can also be used for direct reading of the various parameters. This is conveniently done due to its compact design, low drag force and easy handling. Data can be stored internally and read after retrieval or be read in real time on deck by use of the profiling cable.

Meter comprises:

  • A Vane Plate (3681) to stabilise the meter during profiling (stops spin).
  • Stainless Steel Mooring Frame made to facilitate easy installation and removal of the instrument by use of two knobs.
  • Doppler Current Sensor (Current speed sensor) - Range of speed recorded 0-300 cm s-1 with a 0.3 cm s-1 resolution.
  • Hall Effect Compass - Direction recorded with 0.35 ° resolution, 5 ° for 0.15 ° tilt and 7.5 ° for 15-35 ° tilt.
  • Thermistor (Temperature sensor) - With selectable wide, low, high and Arctic ranges. Standard range -2.70 to 21.77 °C, accuracy 0.05 °C, resolution 0.1% of selected range, 63% response time (12 sec).
  • Inductive Cell Conductivity Sensor (optional) - Range 0 to 75 mS cm-1, standard resolution 0.002 mS cm-1.
  • Pressure Sensor (optional) - Silicon piezoresistive bridge, standard range 0 to 3500 kPa, resolution 0.1% of range.
  • Turbidity Sensor (optional) - Optical back-scatter sensor, resolution 0.1% of full scale, (RCM 11 depth capacity 2000 m).
  • Oxygen Sensor (optional) - Oxygen optode, range 0 to 500 µM, resolution < 1µM, response time 60 sec, depth capacity 6000 m.
  • Data storage units DSU 2990 and 2990E are standard data storage devices for Aanderaa data collecting instruments.

A built-in quartz clock allows the time of the first measurement to be recorded in the DSU. The measuring system is made up of a self-balancing bridge with sequential measurement of 10 channels and solid state memory. Channel 1 is a fixed reference reading for control purposes and data identification. Channels 2 and 3 represent measurement of current speed and direction. The direction is found by the use of measurements along two orthogonal axis and linking them to true north by use of an internal compass reading. The instrument can operate continuously or in eight intervals from 1 to 120 minutes. At 60-minute recording interval the operating time is more than two years. The current speed and direction are averaged over the measuring interval. Channels 4, 5 and 6 represent temperature, conductivity and pressure respectively.

Further information can be found in the manufacturer's instrument specification.

BODC Data Processing

Data Processing

The data arrived at BODC as individual .mat files containing data collected on moorings OP1, OP2, OP3, OP4, OP5, OP6, OP7, CI1 and CI2. They were submitted as part of an accession including several different instruments - ADCP, Aquadopp, RCM8, RCM11, RBRsoloT, SBE37 and SBE39.

Reformatting

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

Some variables included in the RCM11 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.

sigstr dB Signal return amplitude from the water body by in-situ acoustic current meter ASAMACMX dB Not included in final files. See note below

No derived parameters were calculated by BODC. Please note that not all parameters are present in all files.

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.

The signal return amplitude 'sigstr' was reformatted for screening purposes only; as it is not an environmental variable, this parameter is not included in the final reformatted files, however it can be retrieved upon request.

During screening of other instruments in OP2 mooring it became clear that it had suffered several knock-downs throughout the deployment period. Data quality does not seem to be affected but caution should be used when analysing the data.

Originator's Data Processing

Sampling Strategy

Sampling was carried out as part of the BAS LTMS (British Antarctic Survey Long Term Monitoring and Survey) until 2016. From 2016 onwards the moorings are split between 'The Ocean Regulation of Climate by Heat and Carbon Sequestration and Transports (ORCHESTRA)' project and 'Dynamics of the Orkney Passage Outflow (DynOPO)' project.

The projects involve the deployment of moorings CI1, CI2, OP1, OP2, OP3, OP4, OP5, OP6 and OP7 in the Southern Ocean, situated north of Coronation Island and the Orkney Passage in the Weddell and Scotia Sea.

Moorings CI1 and CI2 were deployed from 2005 to 2007 and moorings OP1, OP2, OP3, OP4, OP5 and OP6 have been continuously maintained since 2007 with the addition of OP7 in 2015.

RCM11 data have been collected at 60 minute intervals. Gaps in the series may be caused by either instruments not being recovered, or data not being collected due to instrument malfunction.

Data Processing

Little information is known with regards to the exact details of the calibrations carried out on the mooring data. Data processing, visualisation and calibration were carried out through the use of scripts for Matlab version R2014b produced and ran by the originator.

The originator reported that current direction and velocity components for the 2007 to 2012 data were not corrected for magnetic variation, as at the moorings' sites this is lower than the measurements' accuracy. It was also reported that under some conditions the RCM11s under-read current speeds when compared with a mechanical Vector Measuring Current Meter (VMCM), as indicated by results from Watts et al.. Due to continuing uncertainties regarding which correction would best resolve the different characteristics of these two instruments, the RCM11 measurements were left unmodified by the originator.

Offsets were applied to RCM11 temperature. The values for each deployment/instrument combination is shown in the table below:

Mooring Time period (UT) Depth (m) Serial Number Offset Applied
OP2 2007-02-25 to 2009-02-28 2385 592 0.0500
OP4 2011-03-27 to 2012-07-25 2194 532 0.0170
OP2 2013-04-01 to 2015-03-20 2261 521 0.0162
OP4 2013-04-03 to 2015-03-21 2189 532 0.0140

No temperature offsets were applied to the RCM11s deployed in 2015.

Project Information

BAS Long Term Monitoring and Survey

Introduction

The Long Term Monitoring and Survey project (LTMS) has been running since the British Antarctic Survey (BAS) was created. This project is one of the BAS core projects, with several groups of scientists collecting various types of data e.g biological, geological, atmospheric, among others.

Data collection is achievable through a wide scope of instruments and platforms, e.g. the Antarctic research stations, autonomous instrument platforms deployed on or from BAS research ships, BAS aircrafts, satellite remote sensing and others.

Scientific Objectives

This project was implemented in order to measure change and variability in the Earth system. Its long term duration allows for the monitoring of processes that could be missed in shorter term studies and experiments. The data collected is also used to check and improve the reliability of models used to stimulate and predict the behavior of the Earth system.

The main objectives are:

  • Topographic survey
  • Geosciences survey
  • Biological survey and monitoring
  • Atmospheric and oceanographic monitoring

Data Availability

The data sets obtained through this project are available to the academic community.
