It’s called the Global Positioning System, or \u003ca href=\"http://www.gps.gov/\">GPS\u003c/a>. GPS is comprised of a constellation of satellites orbiting Earth, broadcasting atomically-accurate time down to your smartphone, allowing it to calculate your ever-changing location, even when you’re on the move.\u003c/p>\n\u003cp>The GPS receiver in your smartphone uses trilateration -- a more complex version of triangulation -- to determine its position on Earth. In drawings, trilateration is often illustrated in 2-D using circles. But since GPS deals with satellites and Earth in the real 3-D world, spheres are a better representation of what's actually happening.\u003c/p>\n\u003cp>\u003cstrong>The Story of GPS\u003c/strong>\u003cbr>\nGPS actually begins with the basic human desire to know where we are and where we're going. For centuries, travelers had to rely on the sun, the stars or fixed landmarks to navigate from point A to point B. This crude method worked, but was prone to frequent error.

It changes the climate. We know for example when trees were cut down in the Amazon, there was less precipitation.”\u003c/p>\n\u003cp>One of the team’s main discoveries was that large amounts of water in the Eel River watershed is stored in the massive network of fractures in the rock that can be tens to hundreds of feet thick. This “rock water reservoir” is hidden deep inside the Earth, away from the influence of evaporation. It sits beneath the soil and above the saturated layer commonly called ground water and occupies the deepest part of what hydrologists call the “unsaturated zone”. Many trees reach their deep roots into this matrix of water-filled rock fissures and use the water stored there when other water sources dry out or become unavailable. Different types of rock store water in different ways.\u003c/p>\n\u003cp>“We are thinking of them as different types of sponges in the subsurface in the way they take up and retain moisture and give back that moisture to the vegetation that is rooted into them,” says Dietrich.\u003c/p>\n\u003cp>In additional to discovering the amount of water stored in underground rock fractures, Dawson and his team have learned that different types of trees actually use the “rock water” in very different ways depending on climate conditions. For example, the rock matrix inside slopes of hills is a key water resource for the largest trees in the watershed, like Douglas firs.\u003c/p>\n\u003cp>Hardwood trees like tanoak, madrone and live oaks rely largely on precipitation. But when drier times come, they shift to using the more stable groundwater below the surface and then may draw on some \"rock water\" in later summer and fall.\u003c/p>\n\u003cfigure id=\"attachment_94861\" class=\"wp-caption aligncenter\" style=\"max-width: 900px\">\u003cimg class=\"size-full wp-image-94861\" src=\"http://ww2.kqed.org/quest/wp-content/uploads/sites/39/2015/11/todd_dawson_trapping_vapor_900_675_80auto.jpg\" alt=\"Todd Dawson trapping water vapor in the Eel River CZO.\" width=\"900\" height=\"675\" srcset=\"https://ww2.kqed.org/app/uploads/sites/39/2015/11/todd_dawson_trapping_vapor_900_675_80auto.jpg 900w, https://ww2.kqed.org/app/uploads/sites/39/2015/11/todd_dawson_trapping_vapor_900_675_80auto-400x300.jpg 400w, https://ww2.kqed.org/app/uploads/sites/39/2015/11/todd_dawson_trapping_vapor_900_675_80auto-800x600.jpg 800w\" sizes=\"(max-width: 900px) 100vw, 900px\">\u003cfigcaption class=\"wp-caption-text\">Todd Dawson trapping water vapor in the Eel River CZO. \u003ccite>(Credit: Anthony Ambrose)\u003c/cite>\u003c/figcaption>\u003c/figure>\n\u003cp>Conifers play a larger role in moving water out of the subsurface areas in winter and early spring, Dawson says.

It changes the climate. We know for example when trees were cut down in the Amazon, there was less precipitation.”\u003c/p>\n\u003cp>One of the team’s main discoveries was that large amounts of water in the Eel River watershed is stored in the massive network of fractures in the rock that can be tens to hundreds of feet thick. This “rock water reservoir” is hidden deep inside the Earth, away from the influence of evaporation. It sits beneath the soil and above the saturated layer commonly called ground water and occupies the deepest part of what hydrologists call the “unsaturated zone”. Many trees reach their deep roots into this matrix of water-filled rock fissures and use the water stored there when other water sources dry out or become unavailable. Different types of rock store water in different ways.\u003c/p>\n\u003cp>“We are thinking of them as different types of sponges in the subsurface in the way they take up and retain moisture and give back that moisture to the vegetation that is rooted into them,” says Dietrich.\u003c/p>\n\u003cp>In additional to discovering the amount of water stored in underground rock fractures, Dawson and his team have learned that different types of trees actually use the “rock water” in very different ways depending on climate conditions. For example, the rock matrix inside slopes of hills is a key water resource for the largest trees in the watershed, like Douglas firs.\u003c/p>\n\u003cp>Hardwood trees like tanoak, madrone and live oaks rely largely on precipitation. But when drier times come, they shift to using the more stable groundwater below the surface and then may draw on some \"rock water\" in later summer and fall.\u003c/p>\n\u003cfigure id=\"attachment_94861\" class=\"wp-caption aligncenter\" style=\"max-width: 900px\">\u003cimg class=\"size-full wp-image-94861\" src=\"http://ww2.kqed.org/quest/wp-content/uploads/sites/39/2015/11/todd_dawson_trapping_vapor_900_675_80auto.jpg\" alt=\"Todd Dawson trapping water vapor in the Eel River CZO.\" width=\"900\" height=\"675\" srcset=\"https://ww2.kqed.org/app/uploads/sites/39/2015/11/todd_dawson_trapping_vapor_900_675_80auto.jpg 900w, https://ww2.kqed.org/app/uploads/sites/39/2015/11/todd_dawson_trapping_vapor_900_675_80auto-400x300.jpg 400w, https://ww2.kqed.org/app/uploads/sites/39/2015/11/todd_dawson_trapping_vapor_900_675_80auto-800x600.jpg 800w\" sizes=\"(max-width: 900px) 100vw, 900px\">\u003cfigcaption class=\"wp-caption-text\">Todd Dawson trapping water vapor in the Eel River CZO. \u003ccite>(Credit: Anthony Ambrose)\u003c/cite>\u003c/figcaption>\u003c/figure>\n\u003cp>Conifers play a larger role in moving water out of the subsurface areas in winter and early spring, Dawson says.

The toxin can cause permanent damage to the central nervous system.\u003c/p>\n\u003cp>Anyone with an immune-compromised system is at greater risk for deleterious effects of mercury, which is also neurotoxic to developing brains, making it especially dangerous for pregnant and nursing women, babies, and small children.\u003c/p>\n\u003cp>Mercury is found primarily around the bay in a red rock known as cinnabar. When it settles in waterways, bacteria transform it into a highly toxic form known as methyl mercury, which is easily absorbed by marine plants and the tiny aquatic organisms that eat them.\u003c/p>\n\u003cfigure id=\"attachment_82596\" class=\"wp-caption alignnone\" style=\"max-width: 800px\">\u003ca href=\"http://ww2.kqed.org/quest/wp-content/uploads/sites/39/2015/11/319B_Mercury-8.3.09-7.jpg\">\u003cimg class=\"size-medium wp-image-82596\" src=\"http://ww2.kqed.org/quest/wp-content/uploads/sites/39/2015/11/319B_Mercury-8.3.09-7-800x451.jpg\" alt=\"Mercury is found primarily in a red rock known as cinnabar, which was mined extensively in the South Bay.\" width=\"800\" height=\"451\" srcset=\"https://ww2.kqed.org/app/uploads/sites/39/2015/11/319B_Mercury-8.3.09-7-800x451.jpg 800w, https://ww2.kqed.org/app/uploads/sites/39/2015/11/319B_Mercury-8.3.09-7-400x225.jpg 400w, https://ww2.kqed.org/app/uploads/sites/39/2015/11/319B_Mercury-8.3.09-7-1440x812.jpg 1440w, https://ww2.kqed.org/app/uploads/sites/39/2015/11/319B_Mercury-8.3.09-7-1180x665.jpg 1180w, https://ww2.kqed.org/app/uploads/sites/39/2015/11/319B_Mercury-8.3.09-7-960x541.jpg 960w\" sizes=\"(max-width: 800px) 100vw, 800px\">\u003c/a>\u003cfigcaption class=\"wp-caption-text\">Mercury is found primarily in a red rock known as cinnabar, which was mined extensively in the South Bay. \u003ccite>(Photo by KQED)\u003c/cite>\u003c/figcaption>\u003c/figure>\n\u003cp>“In wildlife, mercury in high concentrations can cause developmental problems, just as it does in humans,” said Choksi. “If you’ve got mercury impairing wildlife and their immune systems, then they’re more susceptible to infectious diseases; they can have cancerous growths. It’s pretty much the same as in the human population.”\u003c/p>\n\u003cp>It doesn’t take much to constitute a problem. Mercury pollution is measured in parts per billion – the amount contained in a drop of water in a backyard swimming pool.\u003c/p>\n\u003cp>“So the amount you might find in an old thermometer is enough to cause significant contamination,” said Bruce Wolfe, executive officer with the \u003ca href=\"http://www.waterboards.ca.gov/waterboards_map.shtml\">San Francisco Bay Regional Water Quality Control Board\u003c/a>, the state agency that oversees water pollution in the Bay Area.\u003c/p>\n\u003cp>So where does all this mercury come from? Mercury enters the bay watershed from a number of sources, including stormwater and wastewater runoff from local oil refineries and cement kilns. Significant quantities also drift through the air from coal-burning power plants in China.\u003c/p>\n\u003cp>But the biggest culprit can be found \u003ca href=\"http://ww2.kqed.org/quest/2008/04/18/mercury-in-the-bay-part-1/\">at very root of California’s history and prosperity\u003c/a>. In the 19\u003csup>th\u003c/sup> century, Gold Rush miners also mined mercury in copious amounts in the cinnabar-rich hills just south of San Jose. To extract mercury, crushed ore was heated in furnaces and transformed into a vapor. As the gas cooled and condensed, it turned into a liquid form known as quicksilver, which is naturally attracted to gold. Sierra miners used it to separate gold from crushed rock.\u003c/p>\n\u003cfigure id=\"attachment_82597\" class=\"wp-caption alignnone\" style=\"max-width: 800px\">\u003ca href=\"http://ww2.kqed.org/quest/wp-content/uploads/sites/39/2015/11/Miners_in_the_Sierras.jpg\">\u003cimg class=\"size-medium wp-image-82597\" src=\"http://ww2.kqed.org/quest/wp-content/uploads/sites/39/2015/11/Miners_in_the_Sierras-800x450.jpg\" alt=\"Sierra miners used quicksilver to separate gold from crushed rock. \" width=\"800\" height=\"450\" srcset=\"https://ww2.kqed.org/app/uploads/sites/39/2015/11/Miners_in_the_Sierras-800x450.jpg 800w, https://ww2.kqed.org/app/uploads/sites/39/2015/11/Miners_in_the_Sierras-400x225.jpg 400w, https://ww2.kqed.org/app/uploads/sites/39/2015/11/Miners_in_the_Sierras-1440x810.jpg 1440w, https://ww2.kqed.org/app/uploads/sites/39/2015/11/Miners_in_the_Sierras-1180x664.jpg 1180w, https://ww2.kqed.org/app/uploads/sites/39/2015/11/Miners_in_the_Sierras-960x540.jpg 960w\" sizes=\"(max-width: 800px) 100vw, 800px\">\u003c/a>\u003cfigcaption class=\"wp-caption-text\">Sierra miners used quicksilver to separate gold from crushed rock. \u003ccite>(Painting by Charles Christian Nahl and August Wenderoth, 1851/1852.
