How good is the data? Data are from many sources Inconsistent become apparent Differences in names used Mistakes in transformations Decimalising lat/lon Needs quality control Data collection driven by priorities Sampling bias; resolution

Quality control Check formal record structure Check date/time Check position In the ocean? In dataset bounding box? Check taxonomy Problem: no reference list
