“…The research was carried out during the 57th and 59th cruises of RV Akademik Mstislav Keldysh in September-October 2007 and 2011, respectively. Climatic conditions over this part of the Arctic during those years were relatively similar (Flint 2010, Platonov et al 2012. Ice cover was completely absent in the Kara Sea in the first part of the autumn.…”

Abstract. The distribution of suspended particulate matter (SPM) concentration in the Kara Sea was analysed based on ship and satellite data during the lowest ice cover periods in the Arctic (2007 and 2011). The distance of the river runoff with terrigenous SPM was recognized up to at least 76–76.5° N on the basis of isotope data and SPM concentrations and composition. The complex studies of SPM in the water column and in the benthic boundary layer provided new information about the supply and transformation of particles in the marine ecosystem.

“…Ice cover was completely absent in the Kara Sea in the first part of the autumn. The largest reduction of the Arctic ice cover was in September 2007, compared with continuous observations from the end of the 1970s (Platonov et al 2012).…”

“…Severtsov Institute of Ecology and Evolution and RAS continue to study the ice distribution and ice volume in the areas of polar bear habitat. The last assessment was done during the time of summer minimum extent along the length of sea ice habitat for polar bears in 2011-2013 using satellite passive microwave sensing of the Russian Arctic seas and adjacent Arctic basin areas (Mordvintsev et al 2011;Platonov et al 2012). Comparing the ice-conditions over a period of satellite-based observations (from 1979 to 2013), it was identified that the sea ice extent was close to the record low value recorded in 2007.…”

“…Satellite data reveal acceleration in the rate of Arctic Ocean sea ice decline from −2.2% per decade between 1979 and 1996 to −10% per decade in the following 10 years [ Comiso et al ., ]. Similarly, there has been a sharp increase in the rate of decline in the minimum sea ice extent, from about −10% per decade from 1979 to 2002 to −40% per decade between 2003 and 2011 [ Platonov et al ., ]. Although decadal scale natural variability in sea ice cover is expected considering the strong influence that slowly varying atmospheric conditions play, continued decline in recent years despite mode changes in key atmospheric indicators (the North Atlantic Oscillation and the Arctic Oscillation) suggests that the regional and global warming trend is the dominating factor in the observed sea ice decline [ Comiso et al ., ].…”

[1] A decade of instrumented mooring data from Barrow Strait in the eastern Canadian Arctic Archipelago reveals connections between sea ice, water characteristics, and zooplankton dynamics on interannual time scales. On the North side of the Strait, the timing of breakup is positively related to the timing of freezeup in the previous year and negatively related to spring water temperature. This suggests that an early freezeup insulates the ocean from a cold autumn atmosphere, allowing heat to be retained until spring when it contributes to early sea ice erosion. There is also a very strong negative association between the timing of freezeup and late summer salinity, suggesting that monitoring of salinity in real time could be used to predict freezeup. A zooplankton biomass index derived from acoustic Doppler current profiler echo intensity data is used to demonstrate that on the North side there are also strong connections between early summer water temperature and the start, length, and productivity of the zooplankton growth season. On the South side of the Strait where currents are stronger, the relationships seen on the North side were not observed. But here integrated zooplankton biomass index and measured currents are used to identify interannual variability in the zooplankton biomass being delivered downstream into Lancaster Sound. Also on the South side, two yearlong records of daily fluorescence profiles reveal a large difference in the phytoplankton biomass being delivered downstream between years and demonstrate a strong relationship between the timing of the spring phytoplankton bloom and that of breakup.Citation: Hamilton, J.
