Submitting data to BODC

Surface underway data submission

BODC aims to ensure that all data incorporated into our database are adequately documented to allow long term viability and future access. Therefore, key data set information (metadata) are important for each data set we receive.

Our 'General guide to data submission' provides details of

BODC undertake the processing of surface underway data collected on cruises associated with projects for which we provide an agreed data management role. If you wish to submit data for one of these please contact the Data Manager for the project.

Information specific to surface underway data for which we do not undertake processing are described below. Metadata may be supplied in any standard document format (i.e. Microsoft Word or text), included in file headers or by providing a literature reference. Please do not be discouraged from sending us data even if some of the information is unavailable. We fully understand that there are many reasons why the standards specified may not be completely achieved.

Instructions for other data types are also available.

Data standard

Ideally, data should be provided as a time series of averages and should be merged with the navigation data. It is advisable that each cruise constitute a single file with one averaged value per parameter, per record. We recommend an averaging interval of one minute in shelf sea areas or two minutes in the open ocean. A record should consist of date, time, navigation; all observed parameters and the number of raw observations used in the average. All relevant corrections and calibrations (laboratory and field) should be applied to the data. Sample data collected for calibration purposes should also be provided.

If the navigation data has not been merged with the observed data, they may be submitted as a separate file. This should be linkable using date and time. The navigation position should be applicable to the middle of the averaging interval.
