Aquarius has been in orbit since 2011, and gathered the data for this image in August 2013.
Australia's interior desert is also clearly visible, with the continent's moisture concentrated along the coasts.
Aquarius gathers data on soil moisture by detecting microwaves given off by the top 2 inches of soil.
Changes in the microwave signal indicate different levels of moisture.
Though not shown in this image, Aquarius also collects data on the concentration of salt at the ocean's surface.
Soil moisture measurements can help predict droughts and floods, and provide crucial information for agriculture.
NASA plans to launch a new satellite, the Soil Moisture Active Passive satellite, this year to gather more data on soil moisture, including
The land is uplifted crust blocks that form parallel ranges but surface water doesn’t run to the ocean. Instead, it evaporates over time leaving a salt flat.
Severe water scarcity could be imminent in the not so distant future. Flooding crop furrows has been an inexpensive irrigation method for over six thousand years. Though traditional, it is very wasteful. An excessive amount of the water evaporates into he air, or soaks into the ground while the plants receive very little. The excess water drains into rivers and underground aquifers. The water running from the furrows is polluted with fertilizers. The constant use of flooding creates erosion, waterlogging and salinization of the soil. 40 percent of the world’s food grows on irrigated soil.
Depletion of ground water may lead to land compaction that in turn decreases its ability to store water.
California is the leading state in agricultural production; however, the state has taken a blow from this four-year drought. Farmers have been forced to re-evaluate their irrigation systems and make necessary changes to conserve water. In order to judge the agricultural water use efficiency, scientists are using a ratio of evapotranspiration of the crop grown to the water applied to the crop. Evapotranspiration is the total evaporation and plant transpiration from land surface to the atmosphere (Marin et al. 2015). Through various

It’s a cold California night in December as David Faraday and Betty Jensen are sitting in their car with heavy feeling towards each other. They are the only ones around, lost in each other’ embrace. This might sound like a love story, but shortly after, their fantasy was ripped apart as they stared into the twisted, evil eyes of a man. That was the last thing they saw, evil, and they died in fear. What followed would be the first confirmed murders by the Zodiac killer. He is the most successful serial killer in the world, claiming thirty-seven lives, though we can only confirm five. Both the fact that the police were not prepared for and the fact that the Zodiac evolved allowed him to elude connection to these lurid murders.
Climate change data was collected from the IPPC AR4 General Circulation Model (GCM). The GCM is regionally dependent and shows the different mixes of greenhouse gas concentration in the atmosphere. (Sheffield & Wood, 2007, p.81) The simple mutlicalar drought index (SPEI) is used to show the climatic water balance. Monthly or weekly difference physiologically equivalent temperature (PET) and precipitation and is calculated at different times. (Vicente-Serrano, Beguería, & López-Moreno, 2009, p. 1699) Streamflow data was obtained from the U.S. Geological Survey Hydrological Climate Date Network (HCDN). (Regonda, Rajagopalan, Clark, & Pitlick, 2004, p.374) Snowfall data is gathered from surveys that were performed by the Natural Resources Conservation Service and precipitation data was gathered from the National Weather Service Cooperative Network. (Regonda, Rajagopalan, Clark, & Pitlick, 2004, p.375)
When I was little, I really didn’t know what astrology was or what your zodiac sign was. When I was growing up, I finally figured out what it all meant and how it worked. From that point on I was instantly clicked. I loved reading my horoscope and when ever I did read it, nine out of ten times it would be right, and that’s why I loved reading my horoscope. It was just something I did every morning, and then I would go throughout my day. Then at night when I would be back on the computer, i would reread them, and realize that most of the time those things did happen, or I did feel that type of emotion.
Despite the grueling work of the police, all the potential suspects have been unsuccessfully convicted. Around 20 letters and cards sent by the Zodiac are the only real trace the Zodiac left of himself. There is no physical evidence that was found at the scene of the crimes,“At least eight descriptions of the Zodiac are out there but those most common were that of a caucasian male, around thirty years old, stocky build, and short reddish brown hair, Zodiac was typically described in dark clothes, military style boots, and glasses. There are composites of the Zodiac but no prime suspects were identified based on the physical description of the killer” (Kelleher,
My favourite constallation is the capricornus. It actually is my zodiac sign. Little magical glowing in the dark stars are fixed to my ceiling, representing the capricornus. It is up there since a few years now. Even when I moved out for three years, it was not removed from the ceiling.
My favorite constellation is Capricornus, because in Latin it means "The Goat". I chose this constellation because goats are my favorite animals and I even own a goat at my muggle house. Capricornus is one of twelve constellations in the zodiac family, and is the 40th largest constellation in the sky. Capricornus's brightest star is Deneb Algedi, Delta Capricorni. This constellation is found in the southern sky.
Australia is both the smallest and oldest continent in the world, and it is the only country that is also a continent. [1] It is an island located between the Indian Ocean and the South Pacific, just south of Indonesia and Papua New Guinea. At 2,941,299 square miles, Australia is the sixth-largest country in the world and only about 150,000 square miles (about the size of Montana) smaller than the continental United States. Its interior land is a flat and sparsely populated desert, but as you move outward the climate changes to grassland, subtropical, tropical, and even temperate in the southeastern region. [1] While more than 70% of Australia is arid, the rest includes a variety of rich environments including flood plains,
A DGPS-based, hydraulically operated penetrometer system mounted on a JD Gator will be used to quantify geo-referenced soil penetration resistance during the growing season. Soil compaction values will be calculated from the measured force required to push a
Abstract—Soil Moisture Sensor Application and Water Control is an automatically water releasing system whenever there is a deficiency of water in agriculture and green house area. Here in this paper, it proposes the new structures of sensors for high sensitivity and three types of moisture level indication systems which can be easily used in fields to save the power, water and crop. The performance comparison made for homemade sensors and readily available sensors, sensitivity improved to the homemade sensors. The high sensitivity and consistency achieved by tin coating to the sensor electrodes. The system monitors the land moisture every time and maintains the fixed water levels by turning on and off the motor. According to the security aspects and repeatability it is good. Its implementation is easy and low cost for affording the system
