Abstract Based on the Baltic Earth Assessment Reports of this thematic issue in Earth
System Dynamics and recent peer-reviewed literature, current knowledge of the effects of …

The Baltic Sea is affected by a range of human induced environmental pressures such as
eutrophication. Here we synthesize the ongoing shift from diatom dominance toward more …

The Baltic Sea is one of the world's marine areas well-covered by both long-term
observations and oceanographic studies. It is also a large coastal area in which …

The coastal zone of the Baltic Sea is diverse with strong regional differences in the physico-
chemical setting. This diversity is also reflected in the importance of different biogeochemical …

Location, specific topography, and hydrographic setting together with climate change and
strong anthropogenic pressure are the main factors shaping the biogeochemical functioning …

While organic carbon (OC) in agricultural mineral soils is widely studied in terms of soil
carbon sequestration and gaseous emissions, discharge-induced OC loss from soil is still …

Understanding marine ecosystem structure and functioning is crucial in supporting
sustainable management of natural resources and monitoring the health of marine …

Dissolved organic matter (DOM) in municipal wastewater can have a detrimental effect on
aquatic ecosystems, as DOM can participate in the global carbon cycle and change the …

In recent decades, the phytoplankton community in parts of the Baltic Sea has shifted from
diatom dominance to co-occurrence of diatoms and dinoflagellates during the spring bloom …

In this study we examine pools of carbon (C), nitrogen (N), and phosphorus (P) in the Baltic
Sea, both simulated and reconstructed from observations. We further quantify key fluxes in …
