Marine science is the study of the ocean and its ecosystems. It encompasses various fields, including oceanography, marine biology, and marine geology. Scientists in this field explore the physical, chemical, and biological processes that occur in the ocean, as well as the interactions between marine organisms and their environment. Research in marine science helps us understand important topics such as climate change, marine conservation, and the impact of human activities on ocean health. By studying the ocean, marine scientists aim to protect marine life and ensure sustainable use of ocean resources for future generations.
