Estuarine research focuses on the study of estuaries, which are coastal areas where freshwater from rivers meets and mixes with saltwater from the ocean. These unique ecosystems are vital for biodiversity, serving as nurseries for many marine species and providing habitats for various plants and animals. Researchers examine the physical, chemical, and biological processes that occur in estuaries to understand their health and functionality. Scientists involved in estuarine research often assess the impacts of human activities, such as pollution and development, on these environments. They also study the effects of climate change, including rising sea levels and changing salinity levels, on estuarine ecosystems. This research is crucial for the conservation and management of estuaries and the resources they provide.
