In this paper, a tracer prognostic differential equation related to the marine chemistry HAMOCC model is studied. Recently the present 5 6 7 8 author found that the Navier -Stokes equation has no unique general solution [Geurdes, 2017]. The following question can therefore be justified. Do numerical solutions, found from prognostic equations akin to the Navier Stokes equation, provide unique [...]

Throughout the Quaternary, lake productivity has been shown to be sensitive to drivers such as climate change, landscape evolution and lake ontogeny. In particular, sediments from Lake Baikal, Siberia, provide a valuable uninterrupted and continuous sequence of palaeoproductivity, which document orbital and sub-orbital frequencies of regional climate change. Here we augment these records through [...]
