Abstract

The input of land-derived sediments, carbon and nutrients is of major importance for the biogeochemistry and ecology of coastal waters, particularly in tropical regions, where the majority of this input occurs. However, knowledge of the fluxes and underlying controls from these regions is still scarce. Therefore, the biogeochemistry of suspended particulate organic matter was studied in the small mountainous Pamba River in Kerala, India. The catchment is densely populated and heavily used for agriculture and other human activities. A unique feature is the Sabarimala temple, the world’s largest pilgrim centre. According to global-scale controls and distribution patterns, the yields and loads of total suspended matter, particulate organic carbon and particulate nitrogen were unexpectedly low, mainly because of low weathering and erosion rates because of Precambrian basement rocks in combination with firm lateritic soils. It indicates that more regional-scale data are required to improve global budgets of river fluxes.
