7. NNMREC Components of Environmental Protocols  Clearly defined objectives ―What hypothesis is being tested?  Data collection ―Hardware selection and configuration ―Sampling scheme  Data analysis and interpretation  Development will be iterative ―Improve based on use ―High degree of collaboration required Aspects of protocols will be site and technology specific

8. NNMREC Why Protocols Matter: Ambient Noise All measurements Measurements excluding sensor- induced pseudo-noise Mean levels >5 dB lower Maximum noise levels 10 dB lower Different analysis leads to different conclusions

9. NNMREC Information Sharing  Lack of data sharing between projects often cited as a barrier to resolving environmental uncertainty  Volume of raw data can be staggering  Context of collection matters Is this practical? Distinguish between data and information
