Search tips:

- Use only one search field at a time.

- Searches using multiple fields will require that BOTH search conditions be met. This is a good way to find specific conditions.


Some examples:
  • If no search terms are entered, you will recieve a list of EVERY site sampled by the MBSS.


  • A search on Patuxent in the stream name field returns 121 different monitoring sites!


  • If Patuxent and Anne Arundel County are selected, only 11 results will be displayed.
