“…The Baltic Sea is a unique system: it is enclosed with relatively poor circulation, has a low salinity and does not exchange much with the North Sea. Further, it is highly eutrophic, such that the deep waters are often depleted in oxygen and exhibit high pCO 2 and hence low pH (Kuss et al, 2006;Omstedt et al, 2009). During the spawning season, Baltic cod spend most of their time in waters with a salinity of at least 12 and oxygen levels above 4 ml l −1 (Schaber et al, 2009), limits that also determine egg survival.…”

Effect of ocean acidification on marine fish sperm (Baltic cod: Gadus morhua)

Abstract.Ocean acidification, as a consequence of increasing marine pCO 2 , may have severe effects on the physiology of marine organisms. However, experimental studies remain scarce, in particular concerning fish. While adults will most likely remain relatively unaffected by changes in seawater pH, early life-history stages are potentially more sensitive -particularly the critical stage of fertilization, in which sperm motility plays a central role. In this study, the effects of ocean acidification (decrease of pH T to 7.55) on sperm motility of Baltic cod, Gadus morhua, were assessed. We found no significant effect of decreased pH on sperm speed, rate of change of direction or percent motility for the population of cod analyzed. We predict that future ocean acidification will probably not pose a problem for sperm behavior, and hence fertilization success, of Baltic cod.

“…Closer to shore the effects of atmospheric CO 2 on coastal seawater pH are complicated by local effects of run-off, eutrophication, upwelling, atmospheric deposition and remineralisation, all of which also influence local biogeochemistry (Doney et al 2007;Omstedt et al 2009Omstedt et al , 2010. Consequently, coastal pH is more variable and difficult to predict than that of the open ocean (Andersson et al 2005).…”

How will Ocean Acidification Affect Baltic Sea Ecosystems? An Assessment of Plausible Impacts on Key Functional Groups

Increasing partial pressure of atmospheric CO 2 is causing ocean pH to fall-a process known as 'ocean acidification'. Scenario modeling suggests that ocean acidification in the Baltic Sea may cause a B3 times increase in acidity (reduction of 0.2-0.4 pH units) by the year 2100. The responses of most Baltic Sea organisms to ocean acidification are poorly understood. Available data suggest that most species and ecologically important groups in the Baltic Sea food web (phytoplankton, zooplankton, macrozoobenthos, cod and sprat) will be robust to the expected changes in pH. These conclusions come from (mostly) single-species and single-factor studies. Determining the emergent effects of ocean acidification on the ecosystem from such studies is problematic, yet very few studies have used multiple stressors and/or multiple trophic levels. There is an urgent need for more data from Baltic Sea populations, particularly from environmentally diverse regions and from controlled mesocosm experiments. In the absence of such information it is difficult to envision the likely effects of future ocean acidification on Baltic Sea species and ecosystems.

“…Biological activity is one explanation for the lower air-sea CO 2 in the coastal region in March-April and October compared to the open ocean region. The biological activity is higher along the coast at these times (Schneider, 2011) due to upwelling near the coast (Omstedt et al, 2009;Norman et al, 2013a); this has the effect of reducing the CO 2 emitted to the atmosphere. In the coastal region we observed a change in the sink between the first 5 years between 1998 and 2002 and the last 5 years between 2007 and 2011 (Fig.…”

“…In recent years, detailed field studies of CO 2 fluxes have taken place in a few areas, such as the East China Sea, northwest European Shelf, Baltic Sea, and North Sea (Chen and Wang, 1999;Frankignoulle and Borges, 2001;Borges and Frankignoulle, 2002;Borges et al, 2003). However, only limited information about these CO 2 fluxes is available on a global scale (Liu et al, 2000b, a;Cai et al, 2003;Chen et al, 2003;Omstedt et al, 2009;Norman et al, 2013b).…”

Abstract. In this article, we present the first climatological map of air-sea CO 2 flux over the Baltic Sea based on remote sensing data: estimates of pCO 2 derived from satellite imaging using self-organizing map classifications along with class-specific linear regressions (SOMLO methodology) and remotely sensed wind estimates. The estimates have a spatial resolution of 4 km both in latitude and longitude and a monthly temporal resolution from 1998 to 2011. The CO 2 fluxes are estimated using two types of wind products, i.e. reanalysis winds and satellite wind products, the higher-resolution wind product generally leading to higher-amplitude flux estimations.Furthermore, the CO 2 fluxes were also estimated using two methods: the method of Wanninkhof et al.
