The Runoff Simulation is an animated version of the Site Storm Model package of Model My Watershed. It allows users to learn how land use and soil together determine whether rainfall infiltrates into the soil, runs off into streams or is evaporated and transpired by plants."

Estuaries are critically important ecosystems, yet they are also some of the most impacted by human activities. In this module, students will use real data to investigate the water quality characteristics of an estuary (water temperature, salinity and oxygen), the relationship between these parameters, and the effect that water quality has on estuarine organisms. Explore the Water Quality activity and download the Teacher's Guide.

The coast has always been our first line of defense against hurricanes for southeast Louisiana. Recognizing this, Pontchartrain Conservancy (PC) developed the Multiple Lines of Defense Strategy designed to help save our coast. In the simplest terms, this strategy highlighted below shows how natural features of our coast (like barrier islands, marshes, and ridges) compliment man-made features (like levees) to protect the Greater New Orleans area from hurricanes.

Urbanization would appear on the surface a natural course of creation by humans. Cities grow with populations; the idea seems clear yet there is more than just a growth in population that lies behind each unique city expansion. St. Tammany Parish, a suburb parish of New Orleans, Louisiana, that has its own distinct history like many other counties in the United States... Early growth in St.

Tracing Monique Verdin's quest to find a place in her Native American community as it suffers from decades of environmental degradation. When she returns to Louisiana to reunite with family, she sees that the traditional way of life is threatened by a cycle of man-made environmental crises. Monique must overcome the loss of her house, her father and her partner, and redefine the meaning of home."

For over 20 years NASA has been tracking the global surface topography of the ocean in order to understand the important role it plays in our daily lives. Climate change is causing our ocean to warm and glaciers to melt, resulting in sea level rise.

There has been a growing of public awareness of plastics found in the ocean environment. Plastics are found at the top and within the water column, in ocean floor sediments, and within beach material. This activity will demonstrate the ease of movement of plastics from your home directly into the ocean environment. Students will explore the typical products which contain plastics and learn how to calculate the concentration of plastics found in a chosen personal care product.

Persistent plastics, with an estimated lifetime for degradation of hundreds of years in marine conditions, can break up into micro- and nanoplastics over shorter timescales, thus facilitating their uptake by marine biota throughout the food chain. These polymers may contain chemical additives and contaminants, including some known endocrine disruptors that may be harmful at extremely low concentrations for marine biota, thus posing potential risks to marine ecosystems, biodiversity and food availability.

Marine life, as we know it, is suffering irreparable damage from the chemical pollution of the waters and the millions of tons of mismanaged waste dumped in the oceans each year. The result is a planetary crisis with over 100 million marine animal's lives get lost every year, and the decay of the ocean's ecosystem.
