forget that the majority of our earth is covered in oceans and freshwater. Almost two thirds of the world’s population lives within 250 miles of an ocean coastline. One of the many issues we are facing in our waters is saltwater intrusion and salinization. Saltwater intrusion and salinization is defined as the increase of chloride ion concentrations in freshwater aquifers or more simply put the movement of saline water into freshwater aquifers. When fresh water is withdrawn at a faster rate than

Crayfish – also called crawfish‚ crawdads‚ freshwater lobsters‚ or mudbugs – are freshwater crustaceans resembling small lobsters‚ to which they are related; taxonomically‚ they are members of the superfamilies Astacoidea and Parastacoidea. They breathe through feather-like gills and are found in bodies of water that do not freeze to the bottom. They are mostly found in brooks and streams where there is fresh water running‚ and which have shelter against predators. Most crayfish cannot tolerate polluted

This would be the first solar desalination facility California has. Who is building the facility?

Background information Daphnia Magna is an arthropod that can grow up to 5 mm. It is a filter feeder meaning it feeds off of suspended particles in the water. Daphnia can consume particles that range from 1µ to 50µ. The heart of Daphnia is located dorsally meaning it’s located in the back. The heart rate of Daphnia can range due to many variables‚ one being temperature. "At a temperature averaging 20o C its heart rate is about 200 beats per minute."2 As the temperature surrounding the Daphnia

water? Purpose: I want to know why the egg floats in fresh water and not salt water. I want to know if the egg will float in salt water‚ Also this shows why materials float easier in saltwater and sink in freshwater. Research: Since the egg’s density is higher than the density of freshwater the egg will sink. Density is mass per unit volume‚ which means a measure of how much mater is in a certain volume. If you add enough salt the egg will float again. The salt makes the water denser because the

This can happen in tropical lagoons with little freshwater input (salinity 35 ppt. Hypersaline lagoons Indian river lagoon‚ 42 ppt has been recorded. Neutral estuary – freshwater input- evaporation.

Its growth has forced scientists to investigate the impact of the increase. It is known that greenhouse gases cause global warming that consequently cause droughts‚ the spread of diseases and changes in the ecosystem among other effects (Reay‚ 2010 p.76). Researchers noted that freshwater microorganism‚ through the process of methanogenesis produces methane
