“…The main reasons for such changes include flow of various water masses with different temperatures, diverse wind speeds and directions, latitudinal changes in solar radiation rates, and presence of sea ice in the northern areas and usually open-waters in the west and southwest regions (ISO, 2010;Matishov et al, 2004;Årthun et al, 2012). For instance, while the annual minimum air temperature in the southern parts varies from -9°С to -6°С, the northern regions experience an annual minimum temperature of -39°С to -20°С (ISO, 2010).…”

“…Water masses in the Barents Sea consist of mainly warm Atlantic waters, Norwegian coastal waters, and cold Arctic waters (ISO, 2010;Loeng, 1991;Løset et al, 1999;Årthun et al, 2012), of which the coastal waters enter the Barents Sea from southeast parallel to the coast of Norway and move eastward towards Pechora Sea, south of Novaya Zemlya. A shown in Figure 13, the Atlantic and Norwegian coastal currents enter the Barents Sea from the south and southwest between the northern coast of Norway and Bjørnøya.…”

Oil and gas (O&G) industry is expanding its activities into Arctic offshore, where is characterised with severe operating conditions and less-developed infrastructure. Such conditions affect the reliability, availability, and maintainability (RAM) of offshore O&G plants, operations, and activities through different scenarios. Plant RAM analysis provides key information for decision-making on, for instance, life-cycle cost management, inventory management, future investments, establishing maintenance policies, and safety-barrier management. Such decisions are of crucial value in Arctic offshore applications due to higher initial and operational costs. Therefore, a thorough evaluation and quantification of the effects of operating conditions on plant RAM performance play a significant role in such decisionmaking processes. In this regard, the aim of this paper is to broadly review and discuss different elements of offshore operating conditions specific to the Barents Sea, and further investigate various effects of such conditions on plant RAM. The present study can provide fundamental information to the academic and industrial sectors involved in the research and development of Arctic offshore O&G facilities and operations.

“…Global ocean-atmosphere CO 2 fluxes have been estimated using diverse methods, including hydrologic models of the carbon system in conjunction with hydrodynamic models (Arthun et al 2012) and in situ measurements of the carbon system variables (alkalinity, DIC, pH, and partial pressure of carbon dioxide [pCO 2 ]) (Bates et al 2011). Empirical relations have been developed between satellitederived sea surface temperatures (SST) and pCO 2 in water (pCO 2water , measured in situ) (Zirino et al 1997, Boutin et al 1999; between chlorophyll a concentrations and pCO 2water (Zhu et al 2009); or between pCO 2water , chlorophyll a concentrations, and SST (Chen et al 2011).…”

Water–air carbon fluxes in the coastal upwelling zone off northern Baja California

M C INTRODUCTIONA topic of great concern and interest for climatologists and oceanographers is to determine how quickly natural and anthropogenic CO 2 is being absorbed by the oceans. The ocean acts as a large CO 2 sink (Takahashi et al. 2009), and a better understanding of the actual rate of ocean uptake of INTRODUCCIÓNUno de los temas más críticos y de gran interés para climatólogos y oceanólogos es conocer qué tan rápido está siendo absorbido el CO 2 natural y antropogénico por el océano. Dado que el océano es un gran sumidero de CO 2 (Takahashi et al. 2009) ABSTRACT. An important challenge in marine science is to quantify the air-sea flux of carbon because of its possible relation to climate change and the decreasing pH in seawater. In coastal areas of Mexico, the magnitude and variability of carbon fluxes between the ocean and the atmosphere is almost completely unknown. Therefore, the objective of this research was to determine the variability of air-sea carbon fluxes in the upwelling system off northern Baja California. A one-year time series of carbon fluxes was generated from data on partial pressure of carbon dioxide (pCO 2 ) from an oceanographic buoy installed immediately south of Punta Banda (Ensenada, Baja California), which measured salinity, temperature, and pCO 2 in the water (pCO 2water ) and air (pCO 2air ) every 3 h during 2009. The study area presented several upwelling events with low sea surface temperatures (≤14 ºC), salinity <34.0, and high values of pCO 2water , which resulted in an export of excess CO 2 in the water to the atmosphere, identifying the area as a temporary source of CO 2 . In contrast, during the relaxation of upwelling, low values of pCO 2water and intermediate surface temperatures resulted in the sea acting as a sink for CO 2 . The average daily flux was 0.6 ± 0.11 mmol C m ; thus, the system turned out to be a net source of CO 2 from the ocean to the atmosphere.Key words: ocean-atmosphere carbon fluxes, coastal zone, upwelling, North Pacific. RESUMEN.Cuantificar los flujos mar-atmósfera de carbono es un reto ambiental importante por su posible relación con el cambio climático y la disminución del pH del mar. En las zonas costeras de México se desconoce casi totalmente la magnitud y la variabilidad de los flujos de carbono entre el océano y la atmósfera. Por tal motivo, el objetivo de esta investigación fue conocer la variabilidad de los flujos de carbono en el sistema de surgencias frente a Baja California norte. Los flujos de carbono se estimaron de una serie de tiempo de la presión parcial de bióxido de carbono (pCO 2 ) generada a través de una boya oceanográfica instalada inmediatamente al sur de punta Banda, (Ensenada, Baja California), la cual medía salinidad, temperatura y pCO 2 en el agua (pCO 2agua ) y el aire (pCO 2aire ), cada 3 h durante 2009. La zona de estudio presentó varios eventos de surgencias, con temperaturas superficiales del mar bajas (≤14 ºC), salinidad <34.0 y valores altos de pCO 2agua , cuyo resultado fue una exportación del exceso de CO 2 en e...

Present global warming is amplified in the Arctic and accompanied by unprecedented sea ice decline. Located along the main pathway of Atlantic Water entering the Arctic, the Barents Sea is the site of coupled feedback processes that are important for creating variability in the entire Arctic air‐ice‐ocean system. As warm Atlantic Water flows through the Barents Sea, it loses heat to the Arctic atmosphere. Warm periods, like today, are associated with high northward heat transport, reduced Arctic sea ice cover, and high surface air temperatures. The cooling of the Atlantic inflow creates dense water sinking to great depths in the Arctic Basins, and ~60% of the Arctic Ocean carbon uptake is removed from the carbon‐saturated surface this way. Recently, anomalously large ocean heat transport has reduced sea ice formation in the Barents Sea during winter. The missing Barents Sea winter ice makes up a large part of observed winter Arctic sea ice loss, and in 2050, the Barents Sea is projected to be largely ice free throughout the year, with 4°C summer warming in the formerly ice‐covered areas. The heating of the Barents atmosphere plays an important role both in “Arctic amplification” and the Arctic heat budget. The heating also perturbs the large‐scale circulation through expansion of the Siberian High northward, with a possible link to recent continental wintertime cooling. Large air‐ice‐ocean variability is evident in proxy records of past climate conditions, suggesting that the Barents Sea has had an important role in Northern Hemisphere climate for, at least, the last 2500 years.
