Narrative Documents

Kongsberg EA600 Single Beam Echosounder

The EA600 is a single beam echosounder with full ocean depth capability designed for bathymetric surveys. It measures water depth by monitoring the travel time of an acoustic signal that is transmitted from the ship, reflected off the seabed and received back at the ship.

The main components of the system are hull-mounted transducers linked to general purpose transceivers (GPTs). Up to four GPTs, each controlling one or more transducers, may be operated simultaneously. The GPT generates a signal, which is transmitted into the water column as an acoustic pulse by the transducer array, and the returning echo is recorded by the GPT. GPTs are in turn linked to a combined display and processor, where adjustments (such as sound-speed corrections) may be applied to the data. Available frequencies span from 12 to 710 kHz, and each GPT may operate at a separate frequency. A variety of transducers is available for water depths up to 11,000 m.

The EA600 stores all data internally but has a USB port which allows the possibility of connecting a CD-ROM/DVD drive to read and write the data. All echo data can be stored as files: bitmap, sample, depth or sidescan data.

In deeper waters, the EA600 supports a multipulse function, allowing for a higher pinger rate. While on passive mode, the pinger is normally attached to a device, with the purpose of tracking and displaying its current depth.

The EA600 replaced the EA500 in 2000.

Kongsberg Seatex Seapath 200 GPS and Gyrocompass

The Seapath 200 is a highly accurate, real-time heading, attitude and position information system that integrates the best signal characteristics of Inertial Measurement Units (IMU) and Global Positioning System (GPS), using a differential GPS method to acquire this data.

The high-rate motion data is obtained from the Seatex MRU5 inertial sensor and two fixed baseline GPS carrier-phase receivers. The raw data is integrated in a Kalman filter in the Seapath Processing Unit. The IMU contains an accurate linear accelerometer and Bosch Coriolis force angular rate gyros (CFG).

This system is equipped to utilise up to six different DGPS reference stations, it checks for consistency within measurements from the different sensors to ensure reliability and rejects noisy data or reports its inaccuracy. The data is available through various output protocols, RS-232, RS-422 and Ethernet.

This instrument is no longer in production; the main characteristics are presented below, and the specification sheet can be accessed here Kongsberg Seatex Seapath 200 .

Sperry Marine MK-37 Gyrocompass

A family of instruments that contain a controlled gyroscope which seeks and aligns itself with the meridian and points to true north. They use the properties of the gyroscope in combination with the rotation of the earth and the effect of gravity. The effects of varying speed and latitude are compensated for by the use of manually operated controls. Models MOD I, MOD O, MOD D, MOD D/E are all with an analog output Step or/and Syncro. MOD VT is the latest model with NMEA Data output as well.

Further specifications for MOD VT can be found in the manufacturer's specification document.

Further information for MOD D/E can be found in the user manual.

BAS Long Term Monitoring and Survey Cruise RRS James Clark Ross JR20080415 (JR186, JR214, JR222, JR223) Underway Navigation Instrumentation Document

Navigation data were obtained through different instruments, but as the Seatex provides the position information for the multibeam system, it is considered as a primary source of data so, unlike the other positioning streams, this stream was transferred. Raw data from the different navigation streams is available upon request.

The following table presents the instruments that collected data during the cruise:

Originator's Data Processing

Navigation data were acquired through the different instruments and stored in individual files, each corresponding to one instrument. The data was logged every second to the SCS system and stored in comma separated format in .ACO files, as processed files in tab delimited with a 30 second interval in .LAB and the header information in .TPL files. The gyrocompass did not record data during the cruise period, so this parameter was originated by the GSP system.

The originator's files exhibit the same common four initial columns:Year (yyyy), Julian day.day fraction (days), Julian day (days), day fraction (days).

The originator's navigation file contained the following channels: time (HHMMSS.SS), lat (degrees), lon (degrees), qq, svc, hdop, altitude (m), dage (s) and dbase.

The ship's orientation data were logged by the gyrocompass onto a one column file: heading (degrees). Bathymetry data were logged by the EA600 echosounder to a file with three columns: ea600-depth_feet (feet), ea600-depth (m) and ea600-depth_fathoms (fathoms).

BODC Data Processing

Parameter codes defined in BODC's parameter dictionary were assigned to originator's variables. No unit conversion was applied as the originator's units are equivalent to the units defined on the BODC vocabulary. Data were loaded into BODC's database using established data banking procedures.

All 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.

Position

A check was run on the position data and no gaps were observed in the data. Several speed fails were identified and data for these instances were interpolated through established procedures.

Ship's velocities

Ship's eastward and northward velocities were calculated from the main latitude and longitude channels. Data exhibit good quality, with no gaps or spikes identified.

Ship's heading

No flags were applied to ship's heading.

Distance Run

Distance run was calculated from the main latitude and longitude channels, starting from the beginning of the cruise.

Bathymetry

Bathymetry data from the echosounder was loaded and screened. N flags were applied to missing data, M flags were applied to dropouts and also reflection observed in the data.

Western Core Box

The British Antarctic Survey undertakes cruises to determine krill biomass as part of the ongoing assessment of the status of the marine ecosystem in the region of South Georgia. This unique time series, known as the Western Core Box, which has taken place since 1996 is funded by Natural Environment Research Council (NERC) British Antarctic Survey Long Term Monitoring programme.

The survey area is located in an on and off shelf survery area (figure.1), which comprises of an acoustic grid survey of 8 transects each of 80 km in length. Standard data collection includes underway biological echosounder acoustic transaects, CTD profiles, stratified and targetted RMT8 hauls of macrozooplankton and micronekton and a set of moorings which provide temporal coverage and a year round set of observations.

The specific aims of the WCB are:

  • To quantify the interannual variability and long-term change in the mesoscale distribution and abundance of Antarctic krill.
  • To quantify the the interannual variability and long-term change in the mesoscale distribution and abundance of other plankton/micronekton.
  • To examine interannual varaibility in the context of environmental variability (climate variability).
  • To examine prey availiability in the context of predator and fishery demand.
