Overview

Ragnar Elmgren is affiliated with Stockholm University in Sweden. Their research primarily focuses on Earth and Planetary Sciences and Environmental Science, with a strong emphasis on oceanography and related environmental processes.

The main subjects of their work involve marine and coastal ecosystems, aquatic ecosystems and phytoplankton dynamics, marine biology and ecology research, oceanographic and atmospheric processes, and marine and fisheries research. Additional research topics include geology and paleoclimatology as well as methane hydrates and related phenomena.

Elmgren has contributed to many scholarly articles published in notable scientific venues. These include:

  • Climate change in the Baltic Sea region: a summary (2022), Earth System Dynamics
  • Cyanobacterial blooms in the Baltic Sea: Correlations with environmental factors (2020), Harmful Algae
  • How oxygen deficiency in the Baltic Sea proper has spread and worsened: The role of ammonium and hydrogen sulphide (2022), AMBIO
  • Baltic Sea transparency from ships and satellites: centennial trends (2022), Marine Ecology Progress Series
  • Effects of Load Reductions on Phosphorus Concentrations in a Baltic Estuary-Long-Term Changes, Seasonal Variation, and Management Implications (2020), Estuaries and Coasts

Elmgren's frequent co-authors include Mati Kahru, Oleg Savchuk, Jakob Walve, Ulf Larsson, and Gregor Rehder. Mati Kahru is the most frequent collaborator with three joint publications, followed by others with two joint publications each.

Their work has appeared most frequently in the journals Harmful Algae and AMBIO, with two publications each. Other venues include Earth System Dynamics, Marine Ecology Progress Series, and Estuaries and Coasts.

Elmgren's subfields of study encompass oceanography, environmental chemistry, atmospheric science, global and planetary change, and ecology. The varying topics within these fields reflect an interdisciplinary approach to studying environmental and marine systems, particularly in the Baltic Sea region.
