RBR TR-1050 Submersible Temperature Recorder

The TR-1050 is a small (230mm x 38mm OD), self-contained, submersible RBR (Ltd) temperature recorder with a calibration to + or - 0.002 o C. Typical calibration drift of 0.002 o C per year has been measured. It can be deployed for a period of up to three years and can collect more than 2,400,000 samples.

The TR-1050 has a measurement range of -5 o C to +35 o C in its standard calibration. It can, however, be configured to measure wider ranges. The logger can be fitted with different thermistors to operate to as low as -40 o C or up to +50 o C The TR-1050 may also be configured to measure a far higher range, if it is fitted with an external probe.

BODC Processing

The data arrived at BODC in Matlab binary .MAT files representing data collected by a temperature recorder from a mooring positioned in the Marguerite Trough, Marguerite Bay, Antarctica which was deployed in conjuction with the Rothera Oceanographic and Biological Time Series (RaTS). These were reformatted to the internal QXF format using BODC transfer function 390. The following table shows how the variables within the matlab files were mapped to appropriate BODC parameter codes:

Originator's Variable Units Description BODC Parameter Code Units Comment
temp degrees Celsius Temperature of the water column by in-situ thermistor TEMPTC01 degrees Celsius Offset applied from reference CTD

The reformatted data were visualised using the in-house EDSERPLO software. Suspect data were marked by adding an appropriate quality control flag, missing data by both setting the data to an appropriate value and setting the quality control flag.

External Data Processing

The RaTS moored TR data were subjected to a number of checks and calibrations externally, prior to be being received by BODC.

Temperature data from moored TR were compared to the temperature data collected from a CTD profile made at the Marguerite Trough site during the mooring deployment. The TR corresponded well with the CTD cast where a small correction (less than 0.05 o C) was made to the time averaged moored data. See table 1 for further details.

Project Information

Rothera Oceanographic and Biological Time Series (RaTS)

The RaTS programme, which has been run by the British Antarctic Survey since 1997, involves the long-term monitoring of the nearshore marine environment. The project has always been funded by the Natural Environment Research Council (NERC); it initially was a discrete project within the BAS marine biological programme but has now been moved to form a component of the BAS Long Term Monitoring and Survey (LTMS) programme.

Scientific Aims

The RaTS programme was started with two broad aims. The first was to provide a suite of oceanographic data that would provide the environmental background to aid interpretation of the nearshore marine ecology. The second was to test a series of broad hypotheses concerned with surface and deep water coupling and environmental forcing of the nearshore oceanic environment. The key questions formulated at the start of the programme were:

1. To what extent is the physics of the upper water column (ice dynamics, thermal characteristics and vertical structure) related to large-scale forcing such as the El-Niño Southern Oscillation?

2. How and to what extent is variability in the physics of the upper water column transferred to biological processes, particularly primary production?

3. How and to what extent does variability in the timing and in the intensity of the summer phytoplankton bloom affect key ecological processes in the benthos, and particularly feeding, growth and reproduction?

To answer these questions an integrated programme of regular oceanographic and biological measurements was implemented. Observations are taken at a fixed station, selected to be safely accessible by boat in summer and snowmobile in winter whilst being well away from normal ship traffic. Operations at this site included regular CTD casts, discrete water sampling and the deployment of three moorings equipped with current profilers and other hydrography sensors.

Marguerite Trough Mooring

The first deployment of the mooring at the Marguerite Trough site in Marguerite Bay, Antarctica occurred on 24th January 2005 and was later recovered on 15th February 2006. Prior to deployment, all sensors were programmed to sample for a duration of a year. However, due to a delay in the recovery, all sensors except for the ADCP have a data gap of ~3 weeks. Both deployment and recovery were carried out onboard the RRS James Clark Ross.

Fixed Station Document

The RaTS site is located in Marguerite Bay, ~4 km from shore and over a water depth of ~520 m. Marguerite Bay is enclosed by Adelaide Island to the north, Alexander Island to the south and the Antarctic Peninsula to the east (Figure 1 and 2). Waters are strongly influenced by the Antarctic Circumpolar Current. Surface waters during summer become warm through insolation and freshened by ice melt. In winter surface waters are generally colder and more saline and characterised by a thick mixed layer which persists into the summer months and is marked by a subsurface temperature minimum (for fuller details please see Meredith et al., 2004 and references therein). When optimal conditions aren't available a secondary site is occupied. In times when fast ice prevented sampling at both the primary and secondary site, a third site is utilised close to the Rothera Research Station. However, only a water sample is collected during this time as the water is too shallow to allow for a cast to be conducted. The following provides details of the sites sampled:

Figures Location of Maguerite Bay, to the west of the Antarctic Peninsula (Meredith et al., 2004) and more specifically the location of the RaTS station (Wallace, 2007)

To compliment the CTD data collected at the RaTS site, three fixed moorings were deployed between 2005 - 2007. The moorings consisted of a suite of sensors including ADCPs, CTDs and sediment traps.
