Rain that falls on a parking lot that has been baking in the sun all day during summer gets super heated and then runs off into streams. ![]() Parking lots and roads, which are examples of impervious surfaces, where water runs off into local streams instead of soaking into the ground, as in natural environments, act as "fast lanes" for rainfall to make its way into streams. This picture shows a typical parking lot after a strong summer rainstorm. It is when the temperature of a water body changes, either by a natural event or by a human-induced event, that the fish break out in a sweat and start to worry. But, if you ask a fish if the temperature of the water it is living in is important, it would yell yes (if it could talk)! In natural environments, temperature is not too much of a concern for aquatic life, since the animals and plants in the water have evolved to best survive in that environment. After all, temperature is not a chemical and it doesn't have physical properties you can see. You might not think that water temperature is considered an important water-quality measurement. Visit Media to see details.Ī hot parking lot can cause heated runoff to enter streams. Impervious surfaces contribute hot water to streams Some compounds are also more toxic to aquatic life at higher temperatures. Warm water holds less dissolved oxygen than cool water, and may not contain enough dissolved oxygen for the survival of different species of aquatic life. Warm stream water is can affect the aquatic life in the stream. The cold soda can keep more of the carbon dioxide bubbles dissolved in the liquid than the warm one can, which makes it seem fizzier when you drink it. Think about how much "bubblier" a cold soda is compared to a warm one. It is the opposite when considering a gas, such as oxygen, dissolved in the water. Water, particularly groundwater, with higher temperatures can dissolve more minerals from the surrounding rock and will therefore have a higher electrical conductivity. The rate of chemical reactions generally increases at higher temperature. Temperature is also important because of its influence on water chemistry. As temperatures get too far above or below this preferred range, the number of individuals of the species decreases until finally there are none. Fish, insects, zooplankton, phytoplankton, and other aquatic species all have a preferred temperature range. Temperature governs the kinds of organisms that can live in rivers and lakes. Temperature exerts a major influence on biological activity and growth. Millions of measurements and analyses have been made that have been influenced by water temperature. Geological Survey (USGS) has been measuring how much water is flowing in rivers, determining the water levels of groundwater, and collecting water samples to describe the quality of those waters for over a century. self-test/attribute-check features aren't officially supported.The U.S. attribute checking and plotting graphs of all acquired data over time. SMARTReporter supports a variety of advanced options and tools including automated S.M.A.R.T self-tests, scheduled S.M.A.R.T. SMARTReporter has completely customizable notification options for all four disk checks including notification via changing application icons, email, alert dialogue, on-screen notification (Growl or OS X 10.8 native), or by launching arbitrary applications / scripts. SMARTReporter can also monitor the free disk space because a completely filled boot disk might lead to system lockups. ![]() sets become "degraded" or just "offline". SMARTReporter can automatically check whether connected R.A.I.D. SMARTReporter has the unique capability to check the system kernel log-file for occurrences of dangerous "I/O errors" to improve the disk failure prediction accuracy. (Self-Monitoring Analysis and Reporting Technology) is a technology built into most modern hard disk drives that acts as an "early warning system" for pending hard disk drive problems. ![]() ![]() status of all compatible connected disks. SMARTReporter periodically checks the built-in S.M.A.R.T. The current status of your hard disk drives is always easily recognizable because SMARTReporter changes its icon (optionally in the menubar) from green to red if a problem occurs. status of your hard disk drives as well as performing other checks for "I/O errors" or R.A.I.D "degradation". SMARTReporter is an application that can warn you of some hard disk drive failures before they actually happen! It does so by periodically polling the built-in S.M.A.R.T.
