title: Secchi disk
text: The Secchi disk, as created in 1865 by Angelo Secchi, is a plain white, circular disk in diameter used to measure water transparency or turbidity in bodies of water. The disc is mounted on a pole or line, and lowered slowly down in the water. The depth at which the disk is no longer visible is taken as a measure of the transparency of the water. This measure is known as the Secchi depth and is related to water turbidity. Since its invention, the disk has also been used in a modified, smaller diameter, black and white design to measure freshwater transparency.

title: Valdes Peninsula
text: The coastline is inhabited by marine mammals, like sea lions, elephant seals and fur seals. Southern right whales can be found in Golfo Nuevo and Golfo San José, protected bodies of water located between the peninsula and the Patagonian mainland. These baleen whales come here between May and December, for mating and giving birth, because the water in the gulf is quieter and warmer than in the open sea. Orcas can be found off the coast, in the open sea off the peninsula. In this area, they are known to beach themselves on shore to capture sea lions and elephant seals.
