Initially data quality is good but deteriorates during mid October when pulse length errors become frequent. Shortly after this spurious valus appear in the speed and thermistor channels, and although an attempt has been made to smooth these the data for November and December should be used with caution. There is also some question as to the validity of the speed values, with 20% of these being at the meter threshold. Is the rotor not turning freely? A feature of the series is that recorded directions are changing even when the speeds are at or below threshold for lengthy periods. Note the similarity between the low-passed series from this meter and that from the meter situated 816 m above it." With regard to this and other comments from CEFAS that we have included here, we (OSU) believe you should be aware that although CEFAS has been extremely careful to warn the user of possible problems with the ADOX data, in fact it is a good dataset. Most of the WOCE current meter data that we have received has come without such warnings, even when it is obvious that some of the records are of poor quality.
