Hi Christian - Thank you for the very interesting talk and congratulations on your selection to deliver the Ingerson Lecture. Your data shows that Himalayan weathering rates were substantially lower in the Neogene relative to today, and, if I understand correctly, weathering rates were fairly constant over the Neogene. Mechanistically, what is driving this geologically rapid shift to higher weathering rates in the modern? Is this a local phenomena in the Himalaya, or might this be happening in other mountain ranges as well?

Dear Christian, ( my appologies if these questions do not make sense or show that I have missed the point but they came up in my head while watching the presentation); You speak of the Himalayan orogeny and its carbon budget, and show the role of organic carbon burial in this budget. My first question is: is this organic carbon formed in the land between mountains and river mouth ( by organisms in the river itself and/or plant litter from land?) and if so, how does this organic carbon loading of the river and finally Bengal bay sediments relate to the orogeny of the Himalayas? Do high weathering rates also mean high potential of the river to erode and transport organic carbon? Or does the weathering produce certain elements that promote organic matter formation within the river? My second question is: do you also find POC in your Bengal fan with a coastal/marine origin; how do you determine in the sediment cores if the organic matter has a riverine origin or a coastal origin? I can imagine that in times of less suspended matter delivered to the bay the turbidity is lower and hence might promote and increase in coastal PP? Would this be something that could be determined from sediment cores in the Bengal fan?
