Continental Shelf Station 2 was a scientific station located 6.4 km offshore in the Gulf of Mexico. It was built in 1964 and operated until the late 1970s. The station was used to understand the ocean and how it works. Scientists measured things like water temperature and salinity, how much oxygen and carbon dioxide were in the water, and how fast the currents were moving. They also studied the plants and animals that live there. The data that was collected was not just for the Gulf of Mexico, but it was also used to learn more about other parts of the ocean. The station was taken down in the late 1970s, but it still helps scientists today better understand the ocean.
