“…Measurements were performed at 20 • C, with the temperature in the cell controlled to within 0.1 • C. In 2000, the working group on carbon dioxide in the north Pacific of the North Pacific Marine Science Organization (PICES) performed an intercalibration of A T in seawater using certified reference materials (CRMs). The results of the intercalibration showed that the alkalinity values obtained by the Bruevich method are in agreement with the standard within ±1 µmol kg −1 when state-of-the-art analytical practice is applied (Pavlova et al, 2008). A T measurements were performed with a precision of ∼ 2 µmol kg −1 with the accuracy set by calibration against CRMs supplied by A. Dickson, Scripps Institution of Oceanography (USA).…”

“…Samples for total alkalinity (A T ) were analyzed in the lab within 1 month using an indicator titration method in which 25 mL of seawater were titrated with 0.02 M HCl in an open cell according to Bruevich (1944) and Pavlova et al (2008). Measurements were performed at 20 • C, with the temperature in the cell controlled to within 0.1 • C.

“…The Arctic dipole (AD), which is characterized by low SLP on the Eurasian side of the Arctic and high SLP on the American side, was present in the summer of 2007 (Fig. 2b) and contributed to a 2007 record minimum sea-ice extent (Overland et al, 2014). The AD pattern persisted for part of the summer during each year following 2007.…”

“…The Barents Sea receives little river input compared to other Arctic shelf seas (Anderson et al, 1998;Schauer et al, 2002). Due to high primary productivity (PP) and cooling during transit to the north, the waters of the Barents Sea constitute the strongest all-season sink for atmospheric CO 2 in the Arctic (Fransson et al, 2001;Omar et al, 2007;Bates and Mathis, 2009;Årthun et al, 2012;Lauvset et al, 2013).…”

The spatial and interannual dynamics of the surface water carbonate system and air–sea CO<sub>2</sub> fluxes in the outer shelf and slope of the Eurasian Arctic Ocean

Abstract. The Arctic is undergoing dramatic changes which cover the entire range of natural processes, from extreme increases in the temperatures of air, soil, and water, to changes in the cryosphere, the biodiversity of Arctic waters, and land vegetation. Small changes in the largest marine carbon pool, the dissolved inorganic carbon pool, can have a profound impact on the carbon dioxide (CO 2 ) flux between the ocean and the atmosphere, and the feedback of this flux to climate. Knowledge of relevant processes in the Arctic seas improves the evaluation and projection of carbon cycle dynamics under current conditions of rapid climate change.Investigation of the CO 2 system in the outer shelf and continental slope waters of the Eurasian Arctic seas (the Barents, Kara, Laptev, and East Siberian seas) during 2006, 2007, and 2009 revealed a general trend in the surface water partial pressure of CO 2 (pCO 2 ) distribution, which manifested as an increase in pCO 2 values eastward. The existence of this trend was defined by different oceanographic and biogeochemical regimes in the western and eastern parts of the study area; the trend is likely increasing due to a combination of factors determined by contemporary change in the Arctic climate, each change in turn evoking a series of synergistic effects. A high-resolution in situ investigation of the carbonate system parameters of the four Arctic seas was carried out in the warm season of 2007; this year was characterized by the next-to-lowest historic sea-ice extent in the Arctic Ocean, on satellite record, to that date. The study showed the different responses of the seawater carbonate system to the environment changes in the western vs. the eastern Eurasian Arctic seas. The large, open, highly productive water area in the northern Barents Sea enhances atmospheric CO 2 uptake. In contrast, the uptake of CO 2 was strongly weakened in the outer shelf and slope waters of the East Siberian Arctic seas under the 2007 environmental conditions. The surface seawater appears in equilibrium or slightly supersaturated by CO 2 relative to atmosphere because of the increasing influence of river runoff and its input of terrestrial organic matter that mineralizes, in combination with the high surface water temperature during sea-ice-free conditions. This investigation shows the importance of processes that vary on small scales, both in time and space, for estimating the air-sea exchange of CO 2 . It stresses the need for highresolution coverage of ocean observations as well as time series. Furthermore, time series must include multi-year studies in the dynamic regions of the Arctic Ocean during these times of environmental change.

Abstract1. The aim of the present study is to assess a conservation priority area (CPA) network proposed for the Russian Arctic seas (47 areas) with regard to underlying oceanographical features and to discuss further development of marine conservation planning.2. The oceanographical features included in the analysis were obtained from the literature or inferred from schemes of climatic oceanography.3. The most frequent oceanographic feature associated with a particular CPA is constant advection of a particular water mass, followed by local water mass transformation, seasonal ice zones, flaw polynyas, and external sources of nutrients. Particularly important are major frontal zones, and coastal phenomena such as coastal/offshore waters transition zones, massifs of fast ice and specific regimes of semi-isolated fjords and bays.4. Each Arctic sea in the study area or its large part (in the Barents Sea) is characterized by a distinct combination of oceanographical features associated with the respective CPAs.5. Although most oceanographical features were not involved in the process of developing the CPA network directly, the resulting CPAs are shown to have a solid oceanographical background.
