Where are marine biomes located?

Marine biomes are predominantly located in the world's oceans, which cover about 71% of the Earth's surface. They can be found in various regions, including coastal areas, open ocean, coral reefs, and deep-sea environments. These biomes are characterized by factors such as salinity, depth, temperature, and light availability, leading to diverse ecosystems. Additionally, marine biomes can extend to estuaries and coastal wetlands, where freshwater meets saltwater.
