Oceans 2.0 API filter: dpo_hydrophoneDataDiversionMode=OD
Low Pass Filtered
Applies to pre-August 2016 data only. This option will cause the search to return results for diverted data that has been low pass filtered only (only files with "-LPF" in the their file-names). For spectral probability density plots and spectrograms, 'Data Diversion Mode: Low Pass Filtered' will appear in the plot title.
Oceans 2.0 API filter: dpo_hydrophoneDataDiversionMode=LPF
High Pass Filtered
Applies to pre-August 2016 data only. This option will cause the search to return results for diverted data that has been high pass filtered only (only files with "-HPF" in the their file-names). For spectral probability density plots and spectrograms, 'Data Diversion Mode: High Pass Filtered' will appear in the plot title.

Downloading HPF (high-pass filtered) data ca can be avoided by selecting the original data option at the bottom of the data selection page of Oceans 2.0, or by specifying dpo_hydrophoneDataDiversionMode=OD when using the API. However, the LPF (low-pass filtered) data still has to be removed using the steps in the attachment below. If a data set previously downloaded already contains LPF and HPF filtered data, you can follow the same steps to remove the filtered data.
