Introduction “Dead Zones” are hypoxic (low-oxygen) regions in oceans, seas, and large freshwater bodies where oxygen levels are too low to sustain most marine life. Scientifically, hypoxia is defined as dissolved oxygen concentration below 2 mg/L, which is lethal for many fish, invertebrates, and benthic organisms. Dead zones have become one of the most pressing…
Introduction Volcanic eruptions are among the most powerful natural phenomena on Earth. They are capable of reshaping landscapes, influencing global and regional climate, disrupting ecosystems, and affecting human settlements. While destructive in the short term, volcanic activity plays a crucial role in soil enrichment, land formation, and maintaining the Earth’s geological balance. Between 2021 and…
Introduction The Northern Atlantic Ocean is a vast and dynamic body of water characterized by complex ocean currents that play a crucial role in regulating global climate, marine ecosystems, and weather patterns. These currents influence navigation, fisheries, and coastal environments. Understanding their origins, movements, and impacts is essential for both scientific and economic purposes. This…
