The North American Water and Power Alliance (NAWPA or NAWAPA; also referred to as NAWAPTA after the proposed governing body, the North American Water and Power Treaty Authority) was a proposed continental water management scheme conceived in the 1950s by the US Army Corps of ...
The beams update many times per second (typically 0.1–50 Hz depending on water depth), allowing faster boat speed while maintaining 100% coverage of the seafloor. Attitude sensors allow for the correction of the boat's roll and pitch on the ocean surface, and a gyrocompass provides accurate heading information to correct for vessel yaw .
The Ogallala Aquifer (oh-gə-LAH-lə) is a shallow water table aquifer surrounded by sand, silt, clay, and gravel located beneath the Great Plains in the United States. As one of the world's largest aquifers, it underlies an area of approximately 174,000 sq mi (450,000 km 2) in portions of eight states (South Dakota, Nebraska, Wyoming, Colorado, Kansas, Oklahoma, New Mexico, and Texas).

Water from both aqueducts is stored first in the large Kensico Reservoir and subsequently in the much smaller Hillview Reservoir closer to the city. [15] The water is monitored by robotic buoys that measure temperature as well as pH, nutrient, and microbial levels in the reservoirs. A computer system then analyzes the measurements and makes ...
In sharp contrast, the period between 14,300 and 11,100 years ago, which includes the Younger Dryas interval, was an interval of reduced sea level rise at about 6.0–9.9 mm/yr. Meltwater pulse 1C was centered at 8,000 years ago and produced a rise of 6.5 m in less than 140 years, such that sea levels 5000 years ago were around 3m lower than ...
The average size of global wildlife populations have declined by 73% in 50 years, a new study by the World Wildlife Fund has found.. The study, titled the 2024 Living Planet Report, monitored ...
