VEMCO Minilog12-TR temperature logger
Description
The VEMCO Minilog12-TR is a miniature data logger that records temperature at a user programmed time interval. It is housed in a waterproof cylinder and the temperature sensor is mounted on a protruding stainless steel probe.
Specifications
Memory | 16k, 32k or 64k. Temperature readings stored in Electrically Erasable Programmable Read Only Memory (EEPROM). Logging duration is between 3 hours and 5 years depending on the logging interval. |
---|---|
Data Retention | 20 years. |
Temperature Range | -5 to 40°C; 0.015°C resolution; ±0.1°C accuracy with factory calibration. |
Maximum Depth | 1000m |
Communication Link | Downloaded via PC interface box. Connects to computer via DB9 connector. No external connections are required. Full memory downloads in 6 minutes for 16k. |
Battery | Internal lithium battery with life of up to 5 years or up to 1200 full deployments. |

BODC Moored Meter Temperature Screening Procedures
BODC screen both the series header qualifying information and the parameter values in the data cycles themselves.
Header information is inspected for:
-
Irregularities such as unfeasible values.
-
Inconsistencies between related information, for example:
- Depths of meter and sea bed
- Times for mooring deployment and for start/end of data series
- Length of record or number of data cycles, the cycle interval, the clock error and the period over which accrued
-
Originator's comments on meter/mooring performance, data quality and parameters measured and the parameters actually present in the data cycles.
Documents are written by BODC highlighting irregularities which cannot be resolved.
Data cycles are inspected via time series plot presentations of parameters. These presentations undergo intrinsic and extrinsic screening to detect infeasible values within the data cycles themselves and inconsistencies as seen when comparing characteristics of adjacent data sets displaced with respect to depth, position or time.
Values suspected of being of non oceanographic origin may be tagged with the BODC flag denoting suspect value.
The following types of irregularity, each relying on visual detection in the time series plot, are amongst those which may be flagged as suspect:
-
Spurious data at the start or end of the record.
-
Obvious spikes of non oceanographic origin.
If a large percentage of the data are affected by irregularities, deemed abnormal, then instead of flagging the individual suspect values, a caution may be documented.
Inconsistencies between the characteristics of the data set and those of its neighbours, as for example between the maximum and minimum values of the parameters (spikes excluded) are, where necessary, documented.
This intrinsic and extrinsic screening of the parameter values seeks to confirm the qualifying information and the source laboratory's comments on the series. In screening and collating information, every care is taken to ensure that errors of BODC making are not introduced.
Project Information
DISCO
DISCO was a multidisciplinary study of the routes, rates and controls on the biogeochemical cycling of dimethyl sulphide (DMS) within a bloom of the coccolithophorid alga, Emiliania huxleyi. The sampling took place on RRS Discovery cruise 241, between 5 June and 1 July 1999, in the northern North Sea. A survey of the region was carried out in order to locate an E. huxleyi bloom suitable for the study. The chosen bloom was labelled with SF6 tracer, and the biogeochemical process study followed the patch as it drifted in a SE direction and was eventually subducted under Norweigian coastal water on 26 June.
The research was organised by NERC's Plymouth Marine Laboratory and involved scientists from 8 institutions. DISCO was funded principally by NERC through Core Strategic and Responsive Mode Funds and by MOD DERA JGS Grant (TD/10/3/5).

Proudman Oceanographic Laboratory Moored Instrument Rig #831
This rig was deployed as part of the DYME DISCO project at site 17/13. It was attached to a drifting hydrosphere RVS/GPS buoy, ARGOS 01954 (B2).
Miniloggers (temperature sensors) were attached to this rig at the following depths below the water surface:
Depth | 10m | 20m | 25m | 30m | 35m | 40m | 45m | 50m | 60m |

Deployed | 17 June 1999 01:46 from RRS Discovery (cruise DI241) |
---|---|
Initial position | 58.9413° N, 2.867° E |
Initial water depth | 100m |
The buoy was recovered on 17 June at 19:03 due to problems with the transmitter and suspect buoyancy.Position:58.871° N, 2.010° E
It was combined with a different hydrosphere buoy, ARGOS 01953 (B4) and redeployed on 17 June at 20:10.
Position | 58.884° N, 3.017° E |

Recovered | 26 June 1999 16:34 |
Position | 58.212° N, 4.129° E |
The following table gives the position of the ARGOS buoy throughout the period of its deployment.
