Online Rock Identification Resources for Geologists and Hobbyists
Geology & LandformExplore the world of rock identification guides While the skies above us have long captivated our attention with their ever-changing cloud formations, the earth beneath our feet holds a treasure trove of geological wonders waiting to be discovered. Just as there are comprehensive guides to help identify the diverse array of clouds, the field of
Why is ocean salinity not a good chronometer?
Historical AspectsOcean salinity is also influenced by tectonic processes, such as the formation and subduction of oceanic crust, the opening and closing of ocean basins, and the weathering of continental landmasses. These processes can affect the input and removal of dissolved minerals from the oceans, leading to long-term changes in ocean salinity that are not necessarily
Estimating River Flow Velocity Using Satellite Imagery
Water BodiesIntroduction to river velocity estimation using satellite imagery Accurate estimation of river flow velocity is critical for a variety of applications, including hydropower management, flood forecasting and water resource planning. Traditional methods of measuring river flow, such as using in-situ flow meters or gauging stations, can be labour intensive, costly and limited in their spatial
Investigating the Precursor Voltage Signals of Cloud-to-Ground Lightning
Safety & HazardsThe relationship between voltage differences and cloud-to-ground lightning The question of whether a voltage difference can precede cloud-to-ground lightning and whether it can be measured over a short distance is of great interest to the atmospheric and lightning communities. Understanding this relationship is crucial to improving our understanding of the underlying mechanisms that drive the
Harnessing the Power of Thunderstorms: The Untapped Energy Potential and Hazards
Safety & HazardsThe power of thunderstorms: Harnessing the energy released Thunderstorms are awe-inspiring natural phenomena that not only captivate our senses, but also hold immense untapped potential. These dynamic atmospheric events release an astonishing amount of energy which, if harnessed properly, could revolutionise the way we approach renewable energy sources. In this article, we look at the
Why are CO2 sensors so expensive when CO sensors aren’t?
Outdoor GearThe Science Behind CO2 and CO Sensors The fundamental difference between CO2 and CO sensors lies in the underlying principles of their operation. Carbon monoxide (CO) sensors are generally less complex and less expensive to manufacture than carbon dioxide (CO2) sensors, which require more sophisticated technology to accurately measure the target gas. CO sensors typically
