  • ObjectivesObjectives To demonstrate the utility of a Network of To demonstrate the utility of a Network of Networks by using waterNetworks by using water--quality data of various quality data of various types (discrete, continuous, probabilistic, moving types (discrete, continuous, probabilistic, moving platforms) and from multiple sources (Federal, platforms) and from multiple sources (Federal, State, Local, universities, volunteer) to be able to State, Local, universities, volunteer) to be able to understand and manage waterunderstand and manage water--quality problems quality problems from the watersheds, estuaries, and to the coastsfrom the watersheds, estuaries, and to the coasts Show examples of applications and models that Show examples of applications and models that can be use to predict outcomes in areas where can be use to predict outcomes in areas where data are not available or to predict future trendsdata are not available or to predict future trends Use dissolved oxygen (vital to all forms of life) and Use dissolved oxygen (vital to all forms of life) and nutrients as examples to nutrients as examples to ““tell the storytell the story””
