| E.A. Gusev. Cenozoic sediment cover neotectonic deformations
in the Yenisei bay area (Kara sea) | 5 | | Considered widespread neotectonic deformations of upper part of the West Siberian Plain sedimentary cover in the lower Yenisei River and Yenisei Gulf area. There are some major types of deformations: gravitational slumping folds and faults; faults at the boundaries of moving blocks of the basement, which are reactivated in the Late Cenozoic and Quaternary. Keywords: neotectonic, Quaternary sediments, the gravitational creep, folds, Yenisei Bay.

characteristics of the frontal zone in the Obskaya guba in early autumn | 15 | | Hydrological and chemical conditions of the frontal zone of the Obskaya Guba during early fall were analyzed based on the detailed survey data. Hydrological structure was described and chemical features revealed the conclusions on transformations of the water masses. The survey also illustrated the influence of the periodic synoptic events on the dynamics and chemical composition of the frontal zone. Keywords: Gulf of Ob, frontal zone, hydrology, nutrients, dissolved organic carbon.
| | E.A. Spiridonov, O.Yu. Vinogradova. The Analysis of the Earth Tide Observations
on Japanese Antarctic Station Syowa | 27 | | During testing of the new native program of tidal prediction ATLANTIDA3.1_2014 the data of gravimetric observations on the Japanese Antarctic station Syowa (Kim et al., 2011) were subjected to substantial additional processing. First of all, these data are interesting due to the rather high latitude of the site location (69º.007 S). This allowed, in particular, to compare with greater reliability two latitudinal distribution of gravimetric amplitude delta-factors: resulting in the construction of a well-known model DDW/NH (Dehant V. et. al., 1999) and calculated in the work (Spiridonov E.A., 2014). At the same time, the stable and accurate superconducting gravimeter located at the station is set just 250 meters from the shoreline, i.e. largely influenced by ocean. In this regard, the interest is also represented in the performance testing in Antarctic of modern oceanic tidal models (in particular, FES2012). As a result of the analysis it was found that the best oceanic tidal model in the Antarctic zone is TPXO7.2. This coincides with the results of work (Kim et al., 2011). However, in general, the range of results obtained by different ocean models proved to be quite large. Nevertheless, it was shown that at high latitudes, regardless of the choice of oceanic tidal model, application of the theoretical amplitude delta- factors for the Earth without the ocean from DDW /NH model in more than 70 % leads to a more distant from the observation results than the use of amplitude factors of our model. Keywords: oceanic loading effect, tidal amplitude delta-factors.

on salinity anomaly formation in the North-West Atlantic and North European basin | 39 | | Influence of fresh water content in the Arctic basin on salinity variations in neighboring water areas of the North Atlantic is examined. Special attention is given to the role of summer melting in formation of anomalies of fresh water flows from the Arctic. Abnormal warm summer seasons in Arctic in 1960s and 2000s are coherent with appearance of negative salinity anomalies in the North Atlantic during the indicated periods. Consistency in salinity anomalies evolution in 1950-60s and 2001–2013s could be a precursor of a new “Great salinity anomaly” in the North Atlantic with the relevant consequences for the climate. Keywords: Arctic, subpolar Atlantic, fresh water inflow, salinity anomaly.
| | G.N. Voinov, A.A. Piskun. The valuation of the tides in the New Port (the Gulf of Ob)
on the sea level data the span of 1977–2012 years | 51 | | The results of treatment and correction of long-term data in the New Port sea level records are stated. Efficiency of a method at an assessment of quality of materials of long-term sea level records and reduction of time series in databases to uniform massifs is noted. By means of a new method steady estimates of the harmonic constants of the constituents in the New Port of sea level records are received. Keywords: tides, tidal analysis, the seasonal variation in the M2 tide, the trends of the M2 tide, the Gulf of Ob, station New Port, sea level dataset.
| | E.A. Zykov, E.A. Gusev. Burial paleovalleys of Chukchi shelf | 66 | | In the Chukchi shelf revealed a network of Pliocene-Quaternary buried paleovalleys. They are predominantly north-west strike and characterize the direction of river flow during the regression of the sea. The position and direction of buried paleovalleys different from submarine valleys, expressed in modern relief bottom. Buried paleovalleys intermittently traced to the modern 100-meter deep marks. Within paleovalleys fixed overdeepened, the formation of which is related to neotectonic processes complicate the structure of an ancient river network. Keywords: Chukchi Sea, burial paleovalleys, Beringia, seismoacoustic studies.
| | I.A. Nemirovskay, A.V. Travkina, I.P. Trubkin. Hydrocarbons in water and bottom
sediments of the White sea | 77 | | The data of long-term studies of hydrocarbons (aliphatic and polycyclic aromatic) in water and bottom sediments of the White Sea were presented. The content of hydrocarbons in water corresponds to their level in other Arctic seas. Geochemical barrier between the Northern Dvina River and Dvina Bay mostly prevents the penetration of pollution into the White Sea serving as a marginal filter). During the flood a lot of pollutants enter the Northern Dvina River. It leads to increase the concentration of hydrocarbons in water and bottom sediments of the river’s mouth. However, despite the low spring temperatures, the transformation of aliphatic hydrocarbons takes place so rapidly, that terrigenous alkanes dominate in the bottom sediments. Oil and pyrogenic compounds are observed in a more stable composition of polycyclic aromatic hydrocarbons. Keywords: oil, hydrocarbons, snow-ice covered, particulate matter, bottom sediments.

transshipment across fast ice | 90 | | The modern approach to engineer support of fast ice unloading security and transportation of cargo is considered in the article. The experience of similar operations in Russian Arctic and use of modern technologies for their enlargement is also considered. Keywords: ice cover, physical and mechanical properties, cargo operations, security, arctic seas.
| | S.V. Popov, M.P. Kashkevich. Two-position GPR sounding: limits and possibilities | 99 | | Theoretical aspects of the one-position and two-position GPR technique are discussed in this paper. Particular attention is paid to the case when the distance to the objects is comparable to the distance between the antennas. It was found the calculations performed by one-position method follows to the extra error for these conditions. The calculations based on the energy performance for two-position GPR are difficult and not accurate. Two-position GPR technique allows to localize objects of investigation. Keywords: GPR technique, two-position sounding, processing of GPR data.
