“…For concentrations of DIC in the Baltic river runoff we use the mean value of the Baltic water flowing into the North Sea (1610 μ mol kg −1 ) from Hjalmarsson et al [2010, Table 1], and for the TA concentration we use the mean surface value of two stations in Baltic Proper (1570 μ mol kg −1 ) [ Hjalmarsson et al , 2008, Table 2]. The runoff TA value from Norway is from the salinity/TA relationship in the Atlantic domain assessed by Nondal et al [2009], where the intercept of the fitted line at S = 0 gives a TA value of 582 μ mol kg −1 .…”

A carbon budget for the Nordic Seas is derived by combining recent inorganic carbon data from the CARINA database with relevant volume transports. Values of organic carbon in the Nordic Seas' water masses, the amount of carbon input from river runoff, and the removal through sediment burial are taken from the literature. The largest source of carbon to the Nordic Seas is the Atlantic Water that enters the area across the Greenland‐Scotland Ridge; this is in particular true for the anthropogenic CO2. The dense overflows into the deep North Atlantic are the main sinks of carbon from the Nordic Seas. The budget show that presently 12.3 ± 1.4 Gt C yr−1 is transported into the Nordic Seas and that 12.5 ± 0.9 Gt C yr−1 is transported out, resulting in a net advective carbon transport out of the Nordic Seas of 0.17 ± 0.06 Gt C yr−1. Taking storage into account, this implies a net air‐to‐sea CO2 transfer of 0.19 ± 0.06 Gt C yr−1 into the Nordic Seas. The horizontal transport of carbon through the Nordic Seas is thus approximately two orders of magnitude larger than the CO2 uptake from the atmosphere. No difference in CO2 uptake was found between 2002 and the preindustrial period, but the net advective export of carbon from the Nordic Seas is smaller at present due to the accumulation of anthropogenic CO2.

“…15 Coastal zones are among the most productive marine regions characterised by high, organic matter accumulation and decomposition (e.g. Hjalmarsson et al, 2010). The Skagerrak, located between the North Sea and the Baltic Sea and in the close proximity to land, has many potential nutrient sources, such as the North Atlantic, Baltic Sea, North Sea, as well as continental discharge and river runoff (Aure and Dahl, 1994;Andersson, 1996;Gustafsson and Stigebrandt, 1996).…”

Abstract.A comprehensive multi-proxy study on two sediment cores from western and central Skagerrak was performed in order to detect the variability and causes of marine primary productivity changes in the investigated region over the last 1100 years. The cores were dated by Hg pollution records and AMS 14 C dating and analysed for palaeoproductivity proxies such as total organic carbon, δ 13 C, total planktonic foraminifera, benthic foraminifera (total as well as abundance of Brizalina skagerrakensis and other palaeoproductivity taxa) and palaeothermometers such as Mg/Ca and δ 18 O. Our results reveal three 5
