• The diurnal cycle of pCO.sub.2 in the coastal region of the Baltic Sea.

  Authors:Martti Honkanen, Jens Daniel Müller, Jukka Seppälä, Gregor Rehder, Sami Kielosto, Pasi Ylöstalo, et al.From:Ocean Science (Vol. 17, Issue 6) Peer-Reviewed

  Nov. 18, 2021362 words Report, Brief articl... The direction and magnitude of carbon dioxide fluxes between the atmosphere and the sea are regulated by the gradient in the partial pressure of carbon dioxide (pCO.sub.2) across the air-sea interface. Typically,...

• Optical model for the Baltic Sea with an explicit CDOM state variable: a case study with Model ERGOM (version 1.2).

  Authors:Thomas Neumann, Sampsa Koponen, Jenni Attila, Carsten Brockmann, Kari Kallio, Mikko Kervinen, et al.From:Geoscientific Model Development (Vol. 14, Issue 8) Peer-Reviewed

  Aug. 13, 2021251 words Case study, Brief ar... Colored dissolved organic matter (CDOM) in marine environments impacts primary production due to its absorption effect on the photosynthetically active radiation. In coastal seas, CDOM originates from terrestrial sources...
