How was the world's highest concentration of chlorophyll found in a heated dome in Costa Rica?
The Costa Rica Thermal Dome (CRTD), located on the west coast of Central America, is a hotspot of marine life. Its unique marine geographical features make this body of water one of the sources of chlorophyll with the highest concentration in the world. The diameter of the dome ranges from 300 to 1000 kilometers, demonstrating its biodiversity and great ecological significance. How was this place formed? How does it work?
The Costa Rica dome is caused by the interaction of strong winds and ocean currents, which causes the upwelling of deep seawater to replace warmer, nutrient-poor surface water. This phenomenon contributes to the huge production of chlorophyll.
The thermal dome's large size and unique location make it a hotbed of marine biodiversity. According to a 2016 survey report by the United Nations Educational, Scientific and Cultural Organization (UNESCO) and the International Union for Conservation of Nature (IUCN), this area has the potential to become a world heritage site in the future. Each year, the dome changes position and size, exhibiting strong seasonal cycles.
The unique hydrogeographic phenomenon of Costa Rica's heated dome causes a strong upwelling here, allowing cold water and high nutrients in the deep sea to flow to the surface, causing phytoplankton and marine life to thrive here. This not only provides a rich source of nutrients for living things, but also promotes the sustainability of the entire ecosystem.
The Costa Rica Dome is full of biodiversity and many forms of marine life. It serves as a crucial habitat for numerous species such as blue whales, sea turtles, and various fish.
The biological quality of algae and plankton in this sea is significantly higher than that of surrounding tropical seas, and the combination of abundant sunlight and cold water results in the highest chlorophyll concentration in the world, approximately 60 milligrams per cubic centimeter. This environment supports a range of marine life, including shrimp, marine mammals such as whales and sea turtles.
Not only is it a hotbed of biodiversity, it is also an important area for fisheries, especially the tuna fishery. In addition, thermal domes are considered important breeding and nursery areas for important species such as the North Pacific blue whale. This means that this area of sea has a vital impact on the maintenance of marine life.
After satellite tracking, it was discovered that the Costa Rica Dome is an important breeding area for North Pacific blue whales and an important migration corridor.
However, as human activity increases, this valuable area faces increasing challenges, such as overfishing and marine pollution. Protecting such ecosystems has become an important task at present. For example, countries such as Costa Rica and Panama have implemented a number of conservation measures to manage fisheries in this area and protect the habitats of marine life.
In order to promote sustainable development, the international community is also continuing its efforts, such as the establishment of the Global Ocean Biodiversity Initiative (GOBI), whose goal is to promote the protection of biological diversity in the marine environment. Through these efforts, it is hoped that the Costa Rican thermal dome and its environment can be effectively protected.
So when considering this fertile sea and its future survival, we should ask how we can more effectively balance the needs of development and conservation.
