Volume and Heat Transports to the Arctic Ocean Via the Norwegian and Barents Seas

摘要: The main aim of this paper has been to present a holistic view the Atlantic water flow along Norwegian Coast and into Barents Sea. It focused on period starting in mid-1990s, with simultaneous arrays moored current meters Svinoy section Sea Opening. These detailed measurements have provided bases for improved estimates means variations fluxes, their forcing mechanisms. Mean volume heat fluxes associated Slope Current (NwASC) are 4.3 Sv 126 TW respectively section, showing no significant trends, 1.8 48 Opening, where positive trends found both measures. probably higher than long-tem mean, since hydrographic data show that periods direct prolongations started late 1970s, when become warmer saltier. close resemblance, throughout record, between temperature Kola AMO-index back early 20 century illustrates importance large-scale longterm system. Although magnitudes these relatively small comparison inter-annual variations, other studies shown them be major ecosystem changes (ACIA, 2005). 2 different effects NwASC inflow similar atmospheric systems noted. results strongly suggest relative distribution entering passing through Fram Strait is very sensitive storm tracks. Thus, predominant tracks may trigger changes, including feedback mechanisms, climate budget Arctic Ocean.
