Project of the Gulf of Mexico Integrated Science program that evaluates the transport and sedimentation of contaminates through the Mississippi River and Atchafalaya River delta to the near-shore Gulf of Mexico. Includes aerial photographs.
Research findings and examples of application to real problems--When can natural processes to reduce, or even destroy, contaminants at toxic waste sites be relied on?
Website of the Gulf of Mexico Integrated Science program to understand the framework and processes of the Gulf of Mexico using Tampa Bay as a pilot study. Links to publications, digital library, water chemistry maps, epiphytes, and field trips.
Tide stage, specific conductance, water temperature, and freshwater inflow at selected Hudson River (New York) gages updated every 4-hours to measure the effects of freshwater withdrawals and upstream movement of the salt front.
Links to real-time data for total dissolved gas, temperature, and barometric pressure in lower Columbia River in Oregon and Washington and to project reports.
Research findings and examples of application to real problems--highly variable conditions cause the production of toxic methyl mercury in the environment which accumulates in fish.
Explanation of chemical contaminants released into aquatic environments by popular sealcoating compounds used in parking lots, with frequently-asked questions, links, and contact information.
