Oxygen loss in the ocean, termed deoxygenation, is a major consequence of climate change
and is exacerbated by other aspects of global change. An average global loss of 2% or more …

In this paper, we outline the need for a coordinated international effort toward the building of
an open-access Global Ocean Oxygen Database and ATlas (GO2DAT) complying with the …

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 …

Dissolved oxygen in the sea is essential for marine fauna and biogeochemical processes.
Decline in the sea water oxygen concentration is considered to be an effect of …

In situ incubations of sediment with overlying water provide valuable and consistent
information about benthic fluxes and processes at the sediment-water interface. In this …

Photoautotrophic marine ecosystems can lock up organic carbon in their biomass and the
associated organic sediments they trap over millennia and are thus regarded as blue carbon …

The phosphorus (P) concentration c1 in the surface layer of the Baltic proper in winter
depends on the land-based P source LPS, and the ocean P source OPS, which are known. It …

Iron, manganese, and trace elements play an important role in the marine carbon cycle as
they are limiting nutrients for marine primary productivity. Water column concentrations of …

Determining accurate rates of benthic nitrogen (N) removal and retention pathways from
diverse environments is critical to our understanding of process distribution and constructing …

Coastal and shelf sediments are central in the global nitrogen (N) cycle as important sites for
the removal of fixed N. However, this ecosystem service can be hampered by ongoing …
