Cau Da

	Vietnam's first active Oceanographic Institute was built in 1922 at Cau Da (Rock Bridge). The ocean in Nha Trang is quite deep. Here the water is approximately 200 m deep. Beyond 100 km, the depth drops to 2000 m. The Oceanographic Institute was built to study the diverse marine life in this area.
The Institute still has samples of sea creatures of this area. Although the institute does not have the modern equipments and facilities to be considered in the same caliber as most western aquariums, it still maintains a fair sample in smaller aquariums. In all, 23 good size aquariums are on display. The institute also has a vast collection of dead samples on display.
