“…The higher communality of increasing Arctic (open water) diatoms and decreasing MIZ diatoms clearly indicate that the background warming observed throughout the Arctic has influenced the local climate in Krossfjorden. The overall increase in SST, SAT and decrease in sea ice conditions are also similar to the longterm variability of annual mean temperature, salinity and ice conditions observed from Grønfjorden, Svalbard, with atmosphere and ocean surface temperatures increasing approximately 2 °C and 1 °C, respectively, from 1970 to 2007, and increasingly late dates for first ice and stable land fast ice formation from 1974 to 2008 [67]. The prolonged open-water conditions (reduced sea ice extent) implied by our reconstructions might suggest the ocean surface-atmosphere interactions have an important influence on conditions in the inner fjords of Svalbard.…”

A high-resolution marine sediment core NP16-Kro1-MCB from Krossfjorden, Western Svalbard is studied to investigate changes in sea surface conditions in the fjord during the last 60 years (1953-2014). The diatom-based reconstruction of August sea surface temperature (aSST) demonstrates a clear warming trend of 0.6 °C through the record. As inferred from Marginal Ice Zone (MIZ) diatoms, surface warming occurs in parallel with a decline in sea ice extent (SIE) during recent decades. Factor analysis identified variations in diatom assemblages representing different water masses, showing a dominance of Arctic water diatoms throughout the period and decadal variations in the sea ice assemblage during periods of peak sea ice extent. The strong dominance of Arctic water diatoms along with increasing aSST suggest prolonged open-water conditions and increased sea ice melting in the region throughout the observed period. The reconstructed ocean surface changes are in line with the background warming occurring over the Arctic region. A comparison with instrumental records from neighboring regions supports the quality of the reconstructions, including the average reconstructed aSST and the magnitude of the warming trend. We suggest that increased CO 2 forcing together with ocean-atmospheric interaction have caused the increasing SST trend and decreasing sea ice presence in Krossfjorden rather than an increasing influence from Atlantic Water, which has amplified changes in many regions of Svalbard.

“…An increase in the average annual SAT found for the period of 1898-2013 reached 0.26°C per 10 years. Maximum warming of SAT was observed in February, March, April, and November. It is consistent with the reports on intensification and warming of the WSC core in the last decades of 20 century and first decades of 21 century (Walczowski et Piechura 2007, Schauer et al 2008, Pavlov et al 2010, Zhuravskiy et al 2012, Marszs et Styszinska 2013.…”

Within last decades, the climate of our planet has underwent remarkable changes. The most notable are those called "Arctic amplification." is the changes comprise a decrease in the area of multi-years ice in 2007 and 2012 in polar regions of the Northern hemisphere, accompanied by the temperature rise of intermediate Atlantic waters, increasing surface temperature. In this paper, an analysis of long-term variability of temperature transformed Atlantic waters (TAW) in the fjords of the West-Spitsbergen island (Isfjorden, Grønfjorden, Hornsund and Kongsfjorden) in the first period (1920-1940) and modern (1990-2009) warming in the Arctic is reported. It is shown that the instrumental observation data corresponds to the periods of rise in temperature in the layer of the TAW and surface air temperature (SAT) for the area of the Svalbard.

“…Long‐term variability of sea ice cover and thickness in the broader region around Svalbard and various individual Svalbard fjords in the more accessible west have been frequently explored (e.g., Gerland et al ., ; Zhuravskiy et al ., ; Onarheim et al ., ; Isaksen et al ., ; Muckenhuber et al ., ; King et al ., ; Onarheim et al ., ; Rösel et al ., ; Pavlova et al ., ). However, according to our knowledge there was no pan‐Svalbard synthesis that would include the more remote fjords in the north and east.…”

The Svalbard archipelago in the Arctic North Atlantic is experiencing rapid changes in the surface climate and sea ice distribution, with impacts for the coupled climate system and the local society. This study utilizes observational data of surface air temperature (SAT) from 1980-2016 across the whole Svalbard archipelago, and sea ice extent (SIE) from operational sea ice charts to conduct a systematic assessment of climatologies, long-term changes and regional differences. The proximity to the warm water mass of the West Spitsbergen Current drives a markedly warmer climate in the western coastal regions compared to northern and eastern Svalbard. This imprints on the SIE climatology in southern and western Svalbard, where the annual maxima of 50-60% area ice coverage are substantially less than 80-90% in the northern and eastern fjords. Owing to winter-amplified warming, the local climate is shifting towards more maritime conditions, and SIE reductions of between 5 and 20% per decade in particular regions are found, such that a number of fjords in the west have been virtually ice-free in recent winters. The strongest decline comes along with SAT forcing and occurs over the most recent 1-2 decades in all regions; while in the 1980s and 1990s, enhanced northerly winds and sea ice drift can explain 30-50% of SIE variability around northern Svalbard, where they had correspondingly lead to a SIE increase. With an ongoing warming it is suggested that both the meteorological and cryospheric conditions in eastern Svalbard will become increasingly similar to what is already observed in the western fjords, namely suppressed typical Arctic climate conditions.
