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.

Neuse River Estuary MODeling and MONitoring (MODMON) Project
http://www.marine.unc.edu/neuse/modmon/homepage.html
As part of the MONitoring phase of MODMON, a variety of water quality parameters are measured on a weekly to monthly schedule at stations along the center of the river. These data provide snapshots of conditions down the center of the Neuse. As part of the MONitoring phase of MODMON, they will be sampling water from the Neuse River on a weekly basis. This will provide a three-dimensional snapshot of conditions along the river. This sampling will include current velocity and hydrographic data.

Students as Scientists - Pollution Prevention through Education
http://smec.uncwil.edu/GLAXO/SAS/index.htm
The Lower Cape Fear River Program is a large-scale water quality assessment program covering the Cape Fear River Estuary and a large portion of the lower watershed. Program objectives are to develop an understanding of the fundamental scientific processes shaping and controlling the ecology of the Cape Fear River system and provide a mechanism for information exchange and public education. Numerous physical, chemical, and biological measurements are collected at thirty-four different sites on a regular basis so biologists, chemists, physicists, and geologists will be able to understand freshwater and estuarine processes in the Cape Fear River basin.

ALERT System
http://www.sna.com/saccowr/index.html">
ALERT is an acronym for "Automated Local Evaluation in Real Time." The ALERT system is comprised of a network of gauging stations that collect rainfall and creek level data in real-time. Each ALERT site transmits standardized data packets to a central computer via radio telemetry. The data is analyzed by specialized software that produces information in a variety of formats for use in evaluating current and future flood threat potential.
