The database is currently off-line as for updating and redesign.

We will unveil a new and improved on-line database in the near future! In the meantime,

school data is still collected for inclusion in the new database.

RIVERQUEST LOGS ON is RiverQuest’s online database that provides access to environmental science data collected by students on Pittsburgh's Three Rivers. The students collect and analyze data during their field experiences in RiverQuest’s Environmental Science School Program.

The database is currently off-line as for updating and redesign.

Water Quality — Water quality data collected using a combination of digital probes, meters and field chemistry kits. Samples are primarily from the surface of each of the Three Rivers within 6 miles of the Point at Pittsburgh.

Birds & Waterfowl — Identification of various birds and waterfowl species encountered during our journey on the Three Rivers of Pittsburgh. A majority of this data is from observations on the Ohio River.

Algae & Plankton — Microscopic organisms that float or swim weakly in the top column of the river. These organisms are collected onboard using an 80 micrometer plankton tow, then examined and identified using compound and video microscopes.

Benthic Macroinvertebrates — Organisms without a backbone visible to the eye that live in the bottom substrate of the river. These organisms are collected on board with a petite ponar bethic grab, hester dendy nest, and off of dockside rocks, and grouped according to their pollution tolerances.

PLEASE NOTE
Data presented in these databases are student collected observations as a part of an educational field experience. While scientific methods are used, each test is a single trial without the usual controls employed in a laboratory situation. All data should be viewed as a reflection of student work and is not meant for monitoring purposes.
