Identifying Trilobite Species: An Earthscience Identification Request
Hiking & ActivitiesTrilobites are some of the most fascinating and diverse creatures that have ever lived. These extinct marine arthropods lived during the Paleozoic Era, from about 540 to 250 million years ago. They are known for their distinctive three-lobed body structure, which gave them their name. Trilobites were incredibly prolific and diverse, with over 20,000 species
The Depths of Productivity: Exploring How Nutrient Cycles Drive Ocean Productivity
Wildlife & BiologyOcean productivity refers to the amount of organic matter produced by photosynthetic organisms, such as phytoplankton, in the ocean. This productivity is essential to support diverse marine food webs and ultimately life on Earth. However, ocean productivity is not uniform throughout the ocean and varies significantly with depth. In this article, we will explore the
The Geologic History of Coastal Hill Formation in Valparaíso, Chile
Water BodiesValparaiso, located on the central coast of Chile, is a city known for its rich cultural heritage and unique urban landscape. What many visitors may not realize is that the city’s stunning hills, which provide a breathtaking backdrop to the bustling port below, are actually the result of millions of years of geological processes. The
Ensuring Water Balance in Urban Infrastructure Construction: Compensating for Water Extraction in Concrete Curing
Climate & Climate ZonesProblem Overview Concrete curing is an essential process in the construction of infrastructure projects such as roads, bridges, and buildings. During the curing process, water is added to the concrete mix to help it harden and gain strength. However, this water is often withdrawn from the water cycle and can have a significant impact on
Exploring the Seismic Discontinuity between the Lithosphere and Asthenosphere: Fact or Fiction?
Geology & LandformThe lithosphere and asthenosphere are two important layers of the Earth’s interior. The lithosphere is the rigid outermost layer of the Earth, which includes the crust and the uppermost part of the mantle. The asthenosphere is the weak and ductile layer below the lithosphere, extending to a depth of about 700 km. The lithosphere and
Exploring the Gap: Why Don’t We Have Live Update Satellites for Monitoring Skin Temperature?
Outdoor GearSkin temperature is an important physiological parameter for monitoring human and animal health and for understanding ecosystem behavior. Infrared thermography is a widely used method for measuring skin temperature, but it has limitations in terms of spatial and temporal resolution. Satellites offer a potential solution to this problem, as they can continuously monitor large areas.
