One‐dimensional evolution of the upper water column in the Atlantic sector of the Arctic Ocean in winter

Abstract: A one‐dimensional model is employed to reproduce the observed time evolution of hydrographic properties in the upper water column during winter, between 26 January and 11 March 2015, in a region north of Svalbard in the Nansen Basin of the Arctic Ocean. From an observed initial state, vertical diffusion equations for temperature and salinity give the hydrographic conditions at a later stage. Observations of microstructure are used to synthesize profiles of vertical diffusivity, K, representative of varying win… Show more

“…The similar TS properties (Figure c) indicate that the water mass is essentially the same, and the change in the profiles is likely due to local processes, rather than, e.g., a shift in the AW layer. This is supported by the findings of Fer et al []. The divergence of the ice field in response to northerly winds could also drive upwelling of the pycnocline, as was previously observed by McPhee et al .…”

“…Using idealized one‐dimensional modeling, Fer et al . [] attribute this mainly to entrainment of warm water from below. On 14 March, a storm accelerated the ice drift, but the ice broke up, and the instruments lost power before the storm peaked.…”

“…The spring/summer storms were less intense and traveled north through the Barents and Kara Seas (Cohen et al, ). The passing storms made a significant impact, for example, on the surface energy budget (Walden et al, ), the entire tropospheric column and boundary layer characteristics (Kayser et al, ), sea ice deformation and drift (Itkin et al, ), and upper ocean mixing and thus turbulent ocean heat fluxes (Fer et al, ; Meyer et al, ; Peterson et al, ). Winter observations and direct observations from Arctic storms are rare, and the N‐ICE2015 campaign provided the first direct integrated observations of the effect of such storms in the Arctic Basin.…”
