A biogeochemical model of vegetation using observed climate data predicts the high northern latitude greening trend over the past two decades observed by satellites and a marked setback in this trend after the Mount Pinatubo volcano eruption in 1991. The observed trend toward earlier spring budburst and increased maximum leaf area is produced by the model as a consequence of biogeochemical vege...
Modeling the nitrogen fluxes in the Black Sea using a 3D coupled hydrodynamical-biogeochemical model: transport versus biogeochemical processes, exchanges across the shelf break and comparison of the shelf and deep sea ecodynamics M.

Abstract. Location, specific topography, and hydrographic setting together with climate change strong anthropogenic pressure are the main factors shaping biogeochemical functioning thus also ecological status of Baltic Sea. The recent decades have brought significant changes in First, rising nutrient loads from land second half 20th century led to eutrophication spreading hypoxic anoxic areas, ...
