“…This Special Issue focuses on the historical framework and recent advances in the understanding of the physical oceanography of the North Atlantic, including Mediterranean Sea, Nordic and Barents Seas, and of the Arctic Ocean. The issue presents the major results of studying the long-term variability of atmospheric forcing (Hauser et al, 2015), and the characteristics of the ocean response to the climate change in the SPNA (Hauser et al, 2015;Kieke and Yashayaev, 2015;Fischer et al, 2015;Mercier et al, 2015;Desbruyères et al, 2015;Wang et al, 2015), Nordic Seas (Yashayaev and Seidov, 2015;Seidov et al, 2015), Arctic Ocean (Rudels, 2015;Rudels et al, 2015;Seidov et al, 2015;Yashayaev and Seidov, 2015) and Mediterranean Sea (Pinardi et al, 2015;Houpert et al, 2015). Two articles (Hu et al, 2015;Sevellec and Fedorov, 2015) focus on the AMOC and on various processes in the Arctic and SPNA connected to its functionality.…”

“…There were numerous attempts to link the variability in these regions to the major climate indices, particularly, the North Atlantic Oscillation (NAO) and Atlantic Multidecadal Oscillation (AMO). The correlations of the ocean climate variables in the northern North Atlantic and Nordic Seas with the NAO and AMO are discussed by Seidov et al (2015) and by Yashayaev and Seidov (2015). The approach used in the latter study helps to account for possible time lags between the observed variability and the climate indices and also helps to understand correlation of higher-frequency variations (e.g., year-to-year changes) of the analyzed variables.…”

“…They review existing estimates of volume and freshwater exchanges through Barents Sea, Bering Strait and the Canadian Arctic Archipelago, as well as runoff and net precipitation, and close the Arctic Ocean volume and freshwater budgets by allowing the excess volume and freshwater to exit through Fram Strait. Seidov et al (2015) report results from a pilot study based on the NODC Arctic Regional Climatology. The work was carried out to track multidecadal ocean climate variability north of 60°N.…”

On the flow of Atlantic water and temperature anomalies in the Nordic Seas toward the Arctic Ocean

et al. 2015

The climatic conditions over the Arctic Ocean are strongly influenced by the inflow of warm Atlantic water conveyed by the Norwegian Atlantic Slope Current (NwASC). Based on sea surface height (SSH) data from altimetry, we develop a simple dynamical measure of the NwASC transport to diagnose its spatio‐temporal variability. This supports a dynamical division of the NwASC into two flow regimes; the Svinøy Branch (SvB) in the southern Norwegian Sea, and the Fram Strait Branch (FSB) west of Spitsbergen. The SvB transport is well correlated with the SSH and atmospheric variability within the Nordic Seas, factors that also affect the inflow to the Barents Sea. In contrast, the FSB is influenced by regional atmospheric conditions around Svalbard and northern Barents Sea. Using a composite analysis, we further relate anomalous strong SvB flow events to temperature fluctuations along the core of Atlantic water. A warm composite anomaly is found to propagate northward, with a tendency to amplify enroute, after these events. A roughly 12 months delayed temperature signal is identified in the FSB. However, also in the Lofoten Basin interior a delayed temperature signal is found, which appears to originate from the NwASC. This study suggests that hydrographic anomalies both upstream from the North Atlantic, and locally generated in the Norwegian Sea, are important for the oceanic heat and salt transport that eventually enters into the Arctic.

Consequences of future increased Arctic runoff on Arctic Ocean stratification, circulation, and sea ice cover

et al. 2016

The Arctic Ocean has important freshwater sources including river runoff, low evaporation, and exchange with the Pacific Ocean. In the future, we expect even larger freshwater input as the global hydrological cycle accelerates, increasing high‐latitude precipitation, and river runoff. Previous modeling studies show some robust responses to high‐latitude freshwater perturbations, including a strengthening of Arctic stratification and a weakening of the large‐scale ocean circulation; some idealized modeling studies also document a stronger cyclonic circulation within the Arctic Ocean itself. With the broad range of scales and processes involved, the overall effect of increasing runoff requires an understanding of both the local processes and the broader linkages between the Arctic and surrounding oceans. Here we adopt a more comprehensive modeling approach by increasing river runoff to the Arctic Ocean in a coupled ice‐ocean general circulation model, and show contrasting responses in the polar and subpolar regions. Within the Arctic, the stratification strengthens, the halocline and Atlantic Water layer warm, and the cyclonic circulation spins up, in agreement with previous work. In the subpolar North Atlantic, the model simulates a colder and fresher water column with weaker barotropic circulation. In contrast to the estuarine circulation theory, the volume exchange between the Arctic Ocean and the surrounding oceans does not increase with increasing runoff. While these results are robust in our model, we require experiments with other model systems and more complete observational syntheses to better constrain the sensitivity of the climate system to high‐latitude freshwater perturbations.
