Please note that an error has been detected in the 12KHz EK60 Sounder water depth data in the processed dataset for voyages ss2011_v02, t01, ss2010_v09, v08, t03 and t02. Unfortunately, due to a change in our Simrad logging system,the required transducer offset of 6.3m has not been incorporated into the water depth. No other data fields except the 12KHz water depth are affected by this error.We will endeavour to reprocess the affected data and update the corrected dataset by Dec 2011.We apologise for the inconvenience. Data was flagged 28/9/2011 and updated with corrected data 13/12/2011.
