Limpopo River Australopithecus fossils from 3.5 million years ago. St Vincent Whitshed Erskine, later Surveyor General for South Africa, traveled to the mouth of the river in 1868-69. A Zambezi shark ("Carcharhinus leucas") was caught hundreds of kilometres upriver at the confluence of the Limpopo and Luvuvhu Rivers in July 1950. Zambezi sharks tolerate fresh water and can travel far up the Limpopo. In 2013, approximately 15,000 Nile crocodiles were released into the river from flood gates at the nearby Rakwena Crocodile Farm. Limpopo River The Limpopo River rises in South Africa, and flows generally eastwards to the Indian Ocean in Mozambique.
Bottom water in temperature and salinity, especially compared to wind-driven surface ocean currents. The bottom water of the Arctic Ocean is more isolated, due to the topography of the Arctic Ocean floor and the surrounding Arctic shelves. Bottom water by an estuary of a river discharging into a saline body exhibits peculiar transport of mud. Due to fresh/saline water intermixing by the estuary, a horizontal isohale gradient is created, with lower salinity levels upstream, which generates the upstream flow of the bottom water. Mud particles carried by river begin settling down as the current and turbulence decrease. When the particles nearly reach
