👉 The coast fluid, also known as the nearshore or littoral zone fluid, refers to the dynamic and complex mixture of water and sediment found in coastal environments. This fluid is characterized by its high turbidity due to suspended particles like sand, silt, and organic matter, which are constantly being stirred up by waves, currents, and biological activities. The coast fluid exhibits strong vertical and horizontal gradients in temperature, salinity, and dissolved oxygen, creating diverse microhabitats that support a wide array of marine life. These conditions are crucial for processes such as nutrient cycling, primary productivity, and the survival of various organisms, from microscopic plankton to larger fish and invertebrates, making the coast fluid a vital component of coastal ecosystems.
