* Salt concentration (Salinity): This varies across different parts of the ocean. The open ocean typically has a higher salinity than coastal areas where freshwater rivers flow in.
* Water temperature: Ocean temperatures fluctuate based on latitude, depth, and season. Warm waters are found near the equator, while colder waters are found at the poles and in deeper regions.
* Plankton: These microscopic organisms are the foundation of the ocean's food web. Their presence and abundance can indicate the overall health of the ecosystem.
* Whale sharks: These majestic creatures are filter feeders that rely on plankton as their primary food source. Their presence can be a sign of a healthy and productive ocean.
Therefore, these factors, along with many others, can be used to create a detailed and nuanced description of a particular ocean environment.
