Signals of the change in monsoonal precipitation at around 2,000 years BP in a sediment core off central west coast of India

Abstract

A 4.80 m long shallow water sediment core, collected from the inner shelf (at 22 m water depth) off Karwar near Kali River mouth is studied for foraminiferal tracers of palaeomonsoons. The climatic history of this core which represents the last 4,500 years approximately (@u14@@C dates) revealed the evidences of a significant change in the intensity of the precipitation around 2,000 years BP
