4.4 Areas for Further Study

ISM is a recent addition to environmental sampling strategies, and there is still much to be learned about it. Areas with recognized information gaps include the following:

  • combining information from multiple DUs after sampling
  • extrapolating the information from one DU to another
  • sampling very large DUs
  • comparison of results from multiple sites

Other potential uses of ISM samples not directly included in the simulation studies are included below. Some considerations are discussed, but additional simulations studies in the future might add further clarification and recommendations for these situations.
