Ocean Surface Temperature (OST) refers to the temperature of the upper layer of the ocean, typically measured at a depth of about one meter. It plays a crucial role in regulating the Earth's climate, influencing weather patterns, and supporting marine ecosystems. OST is affected by various factors, including solar radiation, ocean currents, and atmospheric conditions. Monitoring ocean surface temperature is essential for understanding climate change and its impacts. Scientists use satellites and buoys to collect data on OST, which helps predict severe weather events, such as hurricanes, and assess the health of marine life. Changes in OST can also affect global sea levels and weather systems.
