Temperature and Salinity of RU 15
This shows the salinity of the water based on the date. According to this graph, saltier water sinks to the bottom of the ocean. It shows that fresher water is closer to the coast. Once the glider reached a certain distance from the coast, there was almost no fresh water and mostly salt water.
This shows the temperature of the water based on the date and the depth of the water. The graph shows that the warm water is on top of the cold water. From looking at the salinity graph, we notice that there is a large amount of salt towards the middle depths of the ocean. This causes the temperature in the middle of the ocean to be warmer than the water above it. This is called "spicy" water, meaning its warm and salty.
