Submitting data to BODC

Towed undulator 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

Information specific to towed undulator data (i.e. SeaSoar, Scanfish, Undulating Oceanographic Recorder) 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 and should be merged with the navigation data. A record should consist of date, time, navigation and all observed parameters. 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.

Data split into 'pseudo-CTD' casts are also acceptable. In this context, a 'pseudo-CTD' is defined as the part of the undulator profile collected on the downward undulation of the instrument.

Alternatively, data may be supplied in a grid format, for example, eight-decibar vertical resolution with a horizontal resolution to match the wavelength of the undulator oscillation through the water.

All relevant corrections and calibrations (laboratory and field) should be applied to the data. It should be checked for quality and pre-edited or flagged for erroneous values. Sample data collected for calibration purposes should also be provided.
