  • Landfast sea ice in the Bothnian Bay (Baltic Sea) as a temporary storage compartment for greenhouse gases

    Open AccessN-X Geilfus, Nicolas‐Xavier Geilfus et al.ARTICLEElementa Science of the…2021

    Although studies of biogeochemical processes in polar sea ice have been increasing, similar research on relatively warm low-salinity sea ice remains sparse. In this study, we investigated biogeochemical properties of the landfast sea ice cover in the brackish Bothnian Bay (Northern Baltic Sea) and the possible role of this sea ice in mediating the exchange of greenhouse gases, including carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O)…

  • Long-term mesoscale variability of modelled sea-ice primary production in the northern Baltic Sea

    Open AccessLetizia Tedesco, Elina Miettunen et al.ARTICLEElementa Science of the…2017

    We describe a new ocean-sea ice-biogeochemical model, apply it to the Bothnian Bay in the northern Baltic Sea for the time period 1991–2007 and provide the first long-term mesoscale estimates of modelled sea-ice primary production in the northern Baltic Sea. After comparing the available physical and biogeochemical observations within the study area and the time period investigated with the model results, we show the modelled spatial, intra- and …

  • Assessing the O2 budget under sea ice

    Open AccessSébastien Moreau, Hermanni Kaartokallio et al.ARTICLEElementa Science of the…2015

    The objective of this study was to assess the O2 budget in the water under sea ice combining observations and modelling. Modelling was used to discriminate between physical processes, gas-specific transport (i.e., ice-atmosphere gas fluxes and gas bubble buoyancy) and bacterial respiration (BR) and to constrain bacterial growth efficiency (BGE). A module describing the changes of the under-ice water properties, due to brine rejection and temperat…

  • Role of Sea-ice Biota in Nutrient and Organic Material Cycles in the Northern Baltic Sea

    Jorma Kuparinen, Harri Kuosa et al.ARTICLEAMBIO2007References: 26

    This paper compiles biological and chemical sea-ice data from three areas of the Baltic Sea: the Bothnian Bay (Hailuoto, Finland), the Bothnian Sea (Norrby, Sweden), and the Gulf of Finland (Tvärminne, Finland). The data consist mainly of field measurements and experiments conducted during the BIREME project from 2003 to 2006, supplemented with relevant published data. Our main focus was to analyze whether the biological activity in Baltic Sea se…
