Definition of Rank

  • Rank 1 is a one-dimensional parameter

Narrative Documents

Teledyne RDI's Workhorse Long Ranger ADCP

The Workhorse Long-Ranger acoustic doppler current profiler (Teledyne RD Instruments) is a long-range and long-term self contained ADCP. It has a patented broadband signal (75 kHz) and a standard depth rating of 1500m. It operates effectively between temperatures of -5°C and 45°C and has a velocity accuracy of ±1% ±5mm/s.

The instrument comprises:

BODC Processing

The data arrived at BODC in Matlab binary .MAT files representing acoustic doppler current profiler (ADCP) data from a mooring positioned at the Marguerite Trough in 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 391. The following table shows how the variables within the matlab files were mapped to the appropriate BODC parameter codes:

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.

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 Information

CategoryOffshore area
Latitude67° 34.40' S
Longitude68° 13.50' W
Water depth below MSL520.0 m

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:

Sample Site Latitude Longitude Comments

CTD2 67.58512°S 68.16483°W -
WS3 67.56833°S 68.11869°W Approx. position; sampling just off Biscoe Wharf

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.

Drake Passage

The World Ocean Circulation Experiment (WOCE, 1990-1998) was a major international experiment which made measurements and undertook modelling studies of the deep oceans in order to provide a much improved understanding of the role of ocean circulation in changing and ameliorating the Earth's climate.

The Drake Passage is the narrowest constriction of the Antarctic Circumpolar Current (ACC) - the largest current in the world and connects all three major oceanic basins both horizontally and vertically, thus being a key control in the global overturning circulation.Within the Drake Passage, two repeat hydrographic sections (SR1 and SR1b) were established by WOCE. These were designed to extend measurements collected earlier by the International Southern Ocean Studies (ISOS) programme and have continued beyond the WOCE time-frame.

The original section was SR1 (which also covers part of the A21 one time survey track). Subsequently, the section was shifted to the east (and designated SR1b) in order for it to lie on a satellite ground track as illustrated in the image below.

In addition to the hydrographic measurements, UK research in Drake Passage also includes a network of coastal and deep tide gauges, analysis of satellite altimeter data, and state-of-the-art global numerical modeling.
