Biogeochemical Processes in Aquatic Systems

Biogeochemische Prozesse in aquatischen Systemen

VVZ CR n/a

Last Updated: 2026-02-05 15:19:25

Abstract

Biogeochemical cycles in aquataic systems are discussed from a global or regional perspective, important methods to determine reaction rates and pathways are introduced and typical mechansims are discussed on a molecular level.

Objective

Tackle global and molecular ideas; gather information how rates and pathways of biogeochemical cycles in aquatic systems are determined; understand the relevant coupling mechanisms between biological and geochemical processes.

Content

Biogeochemical cycles in aquatic systems will be discussed from three perspectives: 1) Case studies with a gloabal or regional point of view will document the relevant background information on rates, time-scales and reservoirs of selected element cycles such as C, N, P, S, Fe, Mn Cd, Cu, Mo and As. 2) From a practical perspective we will compare the potential and limits of different methods to quantify biogeochemical processes in aquatic systems. 3) On a molecular level we will discuss mechanisms and pathways of relevant reactions. chapters the C-Si cycle and the stability of planet earth weathering reactions tracing live- aqutic primary production molecular architecture: biomineralization a success story: P limit and water quality management N has many faces: nitrification, denitrification, N-fixation Methanogenesis, methane hydrates and CH4 oxidation Iron limitation - facts and fiction Manganese nodules Cadmium as a nutrient tracing the anoxic ocean:Mo As in groundwater
