This web site contains a database of monitoring data from National Estuarine Research Reserve sites and volunteer sites. Data includes water temperature, water level, salinity, pH, dissolved oxygen, turbidity, and stream flow. Biological variables and bioassment techniques are also included in the dataset. These include water quality, habitat, benthic macroinvertebrates, intertidal organisms, aquatic vegetation, chlorophyll/plankton, and fecal coliform bacteria. In addition to the datasets, the secondary school volunteer sites contain metadata. The metadata includes research descriptors, entry verification, experimental design, research methods, site location and character, data collection period, associated researchers and projects, data table descriptors, and remarks.

This web site provides many classroom activities from the Estuary-Net curriculum. The classroom activities are divided into three levels in order to provide various degrees of involvement in the subject, ranging from lab experiments to single field experiences to long-term monitoring. The benefit of this scaffolding is that schools which do not have easy access to watershed areas can still participate in the Estuary-Net activities by engaging in hands-on/minds-on laboratory activities. All Estuary-Net activities contain objectives, assessments, time needed, materials, procedures,and hypotheses.

Level I activities do not include a field sampling component, but provides classes with a hands-on, inquiry experience that explores the habitat variables tested in later levels. Students use appropriate tools and techniques to gather, analyze, and interpret water quality data in their classroom. In addition, these variables are investigated using current data available at this web site. In these activities, students use telecommunications for collaborative problem-solving. Students relate their data to problems that exist in their local watershed.
