Oceanographic research and development
At the Oceanographic research group, research is based on oceanography, the study of the sea, and links the physics of the sea with biological, geological and chemical processes in the ocean. We are about 20 specialists in fields ranging from oceanography and marine biology to mathematics and computer programming. We increase society's knowledge of the state of the sea to facilitate sustainable management of our ocean.

About the researchFind on this page
Much of SMHI's oceanographic research focuses on our surrounding sea areas; the Baltic Sea, Kattegat and Skagerrak, but we also conduct research for the North Sea and Arctic Ocean.
We are specialists in a number of areas related to marine research, such as marine biology, marine observations, numerical modeling and remote sensing.
We work with marine observational data, oceanographic analysis and the development of computational models and methods. The models are used to make forecasts, study processes and predict future ocean climate.
Our research results are used in products that benefit a wide range of fields, such as oil spill response, shipping, sea rescue, and warnings of algal blooms and high or low water levels.
The results are also used to plan actions needed to meet national environmental quality objectives and to support decision-making on water management, adaptation to future climate and mitigation of climate impacts.
Our oceanographic research focuses on four main research areas: Ocean Climate, Marine Environment, Operational Oceanographic Research and Oceanographic models and processes.
Ocean Climate
The role of the ocean in the climate system
Marine Environment
The sea as a habitat
Operational Oceanographic Research
Sea forecasts and warnings
Oceanographic models and processes
Development and validation
SMHI's oceanographic research unit participates in many national and international projects. We develop ocean modeling and ocean observations and link them with central services and with various issues, both around historical reconstructions and climate change in the Baltic Sea, the North Sea and the Arctic.
Baltic Sea – Effect of a natural Baltic oxygenation-deoxygenation cycle
An in situ observation and modelling study of the effect of a natural Baltic oxygenation-deoxygenation cycle on benthic recycling of P, N, Si and C.
Climate Invasives
Minimizing the negative effects of climate change-induced spread of invasive alien species to marine protected areas using species distribution modelling, stakeholder engagement and effective eradication method.CodeBlue – sustainable eutrophication management of the North-East Atlantic Ocean and Baltic Sea
Harmonised ocean data sets for blue sustainable eutrophication management of the North-East Atlantic Ocean and Baltic Sea.
CS-MACH1 - Marine Citizen Science data Horizon
CS-MACH1 aims at developing a Marine Citizen Science (MSC) data network and associated online hub to support MCS initiatives in the acquisition and integration of data by users.
Numerical models are the main tools in oceanographic research. At SMHI, several advanced models are developed and used to describe the physical and biogeochemical processes in the ocean. Sometimes the models can also be linked together into a multi-model system.
The various model systems are used to make forecasts and enable SMHI to issue warnings and study environmental changes in the marine ecosystem and the effects of climate change.
The main modeling systems today are EC-Earth, NEMO, PADM, SCOBI and SCM.

All of us at the oceanographic research unit
The unit is led by Sam Fredriksson, Elin Almroth-Rosell and Lars Axén.
We publish our research results in international peer-reviewed journals and in SMHI reports. The two most recent publications from SMHI's oceanographic research are:

Unique research project develops ten-year forecasts for the Baltic Sea, the Mediterranean and the Black Sea
A new international research project is tackling the challenge of producing climate forecasts for the oceans for as short period as ten years ahead. “Unique in the world,” says Magnus Hieronymus, research leader at SMHI’s Oceanographic Research Unit. The aim is to help Europe’s marine and coastal areas become more resi...
SMHI leads unique international research project to counteract eutrophication
Eutrophication remains a serious problem for the Baltic Sea and the north-eastern Atlantic. This affects many marine sectors, such as fishing, tourism and aquaculture. SMHI's oceanographic researchers are leading a major European project which will increase the knowledge needed for sustainable marine management, partic...
SMHI recruits Professor of Oceanography
To further strengthen and profile SMHI's expertise in oceanographic research, the position of Professor of Oceanography is now advertised. With a focus on climate effects and other anthropogenic impacts on the ocean, operational oceanography and data assimilation or biogeochemical and physical processes and their impac...
