Major Baltic Inflows come in different flavours

The Baltic Sea is a marginal sea in northern Europe. Anthropogenic eutrophication and related deoxygenation are among its pressing environmental problems. In this context, North Sea water plays a crucial role in maintaining the ecological balance as so called Major…

How to diagnose ocean mixing in models

Ocean mixing is key to distribute heat and nutrients in the world oceans. Despite it’s great importance, it is mainly unconstrained even in ocean models, where numerical effects add to the deliberate parameter settings. Our novel study proposes to use…

Using AI to understand Barents Sea transports

A close cooperation with Norway and Estonia explores the reasons for increasing ocean transports through the Barents Sea opening. Today, the relatively warm and salty waters, that originate for the Atlantic Ocean, have an increasing impact on the Barents Sea…

A new model is born

Within the framework of the BMBF-funded project PrimePrevention we currently develop an ultra-high resolution model setup for the Kiel Bight (Baltic Sea). The new model setup will be named MOMKI. We look forward to the results of the first test…

Press release on Baltic cyanobacteria

The press release by KMS (Kiel Marine Science) of our nature scientific report publication on Baltic Sea cyanobacteria blooms triggered a great interest by many newspapers and the NDR television. A German summary of is still available.

Cyanobacteria blooms in the Baltic Sea

Blue-green algae (or cyanobacteria)  form regularly massive blooms in the Baltic Sea – especially in late summer. The bacteria can produce toxins and add bioavailable nitrogen fixed from the atmosphere to the already over-fertilized system. In the presented study, high-resolution…
