For the first time in serveral years, the El Nino-Southern Oscillation did not dominate regional climate conditions around the globe. A weak La Ni a dissipated to ENSOneutral conditions by spring, and while El Nino appeared to be emerging during summer, this phase never fully developed as sea surface temperatures in the eastern conditions. Neverthe...

In this paper, sea ice in the Central Arctic has been classified in synthetic aperture radar (SAR) images from ENVISAT using a neural network (NN)-based algorithm and a Bayesian algorithm. Since different sea ice types can have similar backscattering coefficients at C-band HH polarization, it is necessary to use textural features in addition to the...

Analysis of modern and historical observations demonstrates that the temperature of the intermediate-depth (150-900 m) Atlantic water (AW) of the Arctic Ocean has increased in recent decades. The AW warming has been uneven in time; a local ~1°C maximum was observed in the mid-1990s, followed by an intervening minimum and an additional warming that...

On the basis of their research and analysis into a corpus of various measurements and calculations, the authors draw a picture of change in the Arctic sea and land ice cover caused by global warming. A decrease in the earth’s cryosphere may lead to negative consequences for humankind, including disturbance of the routine lifestyle of people. This a...
Chapter
In 2008, there was an unprecedented amount of fresh water in the surface layer of the Arctic Ocean. The source of the fresh water was melting sea ice. The heating of the ocean in areas of extreme summer sea ice loss (for instance, summer surface water temperatures in the Beaufort Sea were more than 3°C above average) was contributing to record high...

Introduction: In the last two decades, significant changes have occurred in the Arctic Ocean as well as in the entire Arctic region. The ice cover of Arctic seas, which was gradually (linearly) decreasing from the beginning of the 20th century to the end of it [1], began to shrink rapidly in the 1990s and in the 21st century [2]. Salinity variation...
Article
The variability and state of the Arctic sea ice cover strongly depend on atmospheric conditions as well as ocean dynamic and thermodynamic processes (Alekseev, 1976; Appel and Gudkovich, 1992; Gudkovich et al., 1972; Doronin, 1969; Doronin and Kheisin, 1975; Zakharov, 1981; Zubov, 1938, 1944; Shuleikin, 1953; Wadhams, 1994). A number of parameters...
Article
Understanding the causes of climate change at different time scales is still at the stage of framing scientific hypotheses, and hence requires further detailed investigation. Unfortunately, since climate change is by definition, a long-term phenomenon, it is very difficult to prove or disprove hypotheses. We have an abundance of hypotheses and a de...
Article
In general, the geographical terminology used in this book follows the Russian definitions published in Anon. (O). Treshnikov et al. (1967) define the Arctic Basin as a “near-pole abyssal basin, restricted by the continental slope.” The Beaufort and Lincoln Seas are the marginal zones of the Arctic Basin. The North European Basin encompasses the Gr...
Article
Attempts at super-long forecasts of ice extent for some regions of the Arctic Ocean have a long history. They have mainly focused on the sub-Atlantic part of the Arctic, because long series of ice observations are available for that area. Maksimov (1955) made the first forecast, based on space-geophysical factors and, primarily, a century-long cycl...
Chapter
In addition to the atmosphere, the global climatic system encompasses the global ocean and its sea ice cover as well as features on land that include glaciers, permafrost, rivers, and lakes. These system components continuously interact with each other. A number of studies identify patterns of such interaction, including Formation and Dynamics of M...
Chapter
Regular measurements of Arctic ice thickness began approximately in the middle of the 1930s in the vicinity of a number of polar stations, some of which were closed in the 1990s. To investigate the changes in landfast ice thickness for this study, we chose 11 stations with approximately equal lengths of observational time series. Five of these stat...

This study was motivated by a strong warming signal seen in mooring-based and oceanographic survey data collected in 2004 in the Eurasian% Basin of the Arctic Ocean. The source of this and earlier Arctic Ocean changes lies in interactions between polar and sub-polar basins. Evidence suggests such changes are abrupt, or pulse-like, taking the form o...

Ice information support is a component of hydrometeorological services of ice navigation and other activities in the Arctic that play a decisive role in providing safety and efficiency of sea operations. Multi-year experience of Arctic navigation in Russia has provided several examples of accidents and even losses of men and ships caused by difficu...
Article
The formation mechanism of warm water layers, ignored earlier, in the pycnocline has been discussed, and the role of radiation absorption in the process has been shown. A plan has been proposed for calculating the seasonal transformation of the water temperature profile in the presence of a density discontinuity layer for Arctic seas. An assumption...
