The Gulf Stream flowing north through the Straits of Florida and across the Blake Plateau has many of the characteristics of a graded river. As a graded river, it transports water and sediment in such a manner that it neither erodes nor aggrades its channel. The delicate balance between erosion and deposition is emphasized by the presence of scour depressions and aggradational banks side by side on the bottom, and the well‐sorted Globigerina sand being winnowed over a bottom partly encrusted with manganese nodules. The hydraulic geometry of the Gulf Stream is also comparable to large rivers on land.
