Data quality control and post-processing
- Where are the depth cells positioned in Seareport?
- What are amplitude and correlation, and what do they tell us about data quality?
- Why does my data have low SNR?
- How do blockages affect my data?
- What is acoustic interference? Why does it occur and how to avoid it?
- What is drag down? Why does it occur and how to avoid it?
- What do pitch, roll, and heading tell us and what are they used for?
- QA/QC current measurement (short version)
- QA/QC current measurement (comprehensive)
- How do I exclude one beam from processing in Storm and Ocean Contour?
- What is bin mapping?
- What happens when my instrument is tilted and what actions should I take?
