Ancient coral reef tells the history of Kenya's soil erosion
... For the study, Dunbar and his colleagues donned scuba
gear and dove to the Malindi coral reef near the mouth of the Sabaki River, the second longest river in Kenya. Draining about 11 percent of Kenya's landmass, the Sabaki transports sediments to the sea. The researchers took core samples from two lar...
