The variability (1901–2018) of the average annual values of air temperature, precipitation and sea level with climate averaging (within 30-year climatic periods with a shift of the 30- year “window” in 10-year increments) was analyzed for the coastal zone of the Kaliningrad Oblast (the territory of Russia in the southeastern part of the Baltic Sea)...

Based hydrometeorological data of the MARNET monitoring network, with the sampling interval of 1-hour, from 2003—2016, provided by the German Oceanographic Data Centre (BSH / DOD (M41)), the contributions of the irregular daily variability, the regular daily variability, the synoptic variability, the irregular intra-annual variability, the regular...

Based on an analysis of a series of digital elevation models obtained using a terrestrial laser scanning (TLS) technique, assessment of mean sand transport rate was performed in seasonal scale. Analytical procedures based on the method of finite differences were performed to quantify the volume of moved material. Coastal hydrodynamic processes, as...

This article presents a study of the geomorphological changes of the Curonian Spit during last century. The analysis was conducted for both geological maps and satellite images. The eastward shift the southern part of the Curonian Spit dune ridge with velocity from 2 to 5 m per year takes place. The comparison of the slopes incline directions with...

The Curonian and Vistula Lagoons should be considered to be a part of one natural hydraulic system, as they are connected via two branches of the Prgolya River (the Pregolya River proper and the Deyma branch). The catchment upstream of the point of bifurcation of the Pregolya River into these two branches belongs to both lagoons and comprises 14 %...

The results of comparative analysis of sea surface temperature variations along horizontal sections in the coastal zone are given. The data used had been taken by MODIS spectroradiometers (Aqua, Terra) in the Southeastern Baltic, in periods of coastal upwelling—in the periods of autumn differential cooling over coastal continental slopes (facilitat...

Lithodynamic system is exposed to the changes under climatic variations. Wind regime (especially direction and velocity) is the most important factor influencing the sea bed load. Calculations of the bed load transport constituents were based on the hourly meteorological data, received from the offshore meteostation. These data are unique for the s...

Daily near-midday observations (1996–2010) in the mouth of Pregolia River fulfi lled by the ABIORAS at the Museum Vessel Vityaz, located in the center of Kaliningrad are used for calculations of the temporal variability of the main gydrometeorological parameters and of connection between them. The tendency of growth of an average water level, rise...

The storm situation of the winter period 2011-2012 is discussed. The formation conditions of the mid-January 2012 storm are shown. This storm was not accompanied by strong, but northern winds, however, in combination with high sea level (more than 1 m), it proved to be disastrous for Kaliningrad oblast. The most damaged were the resort areas of the...

The paper focuses on the analysis of interannual, seasonal, and spatial variability of sea surface temperature (SST) in the south–eastern part of the Baltic Sea, including the Curonian and Vistula Lagoons. The data sets are derived from MODIS instrument on Aqua and Terra satellites, and analyzed for 2003–2012. Linear trends of seasonal and interann...

The recent decade variability of air temperature was studied using the hourly observation data of the OIFP D-6-based environmental monitoring. The mean annual temperature is higher now than during the second half of the 20th century. The monthly values are the most variable in winter and the least variable in August. The diurnal variations are also...

The presentation describes several episodes of severe storms in the period of 2011-2014. The aim of this work is to identify the characteristics of severe storms that caused destruction in the coastal zone, assessment of the impact of hydro-meteorological conditions on coastal processes of the coast, revealing the features of the dynamics of the sh...

Thermal regime and processes of ice formation in the South-Eastern Baltic for the period 2003-2013 were observed. According to the character of ice formation processes different types of winters were detected. The degree of ice propagation and stability of the ice cover were estimated. Short periods with different tendencies in ice formation were r...

The results of regular monitoring of the coast of the north-eastern part of the Vistula Lagoon in 2011-2013 are presented.

The assessment of the regional climate changes of hydro-meteorological parameters in the Kaliningrad region was provided for the period 1975-2010. The analysis is based on annual observations of water and air temperatures, atmospheric pressure, wind speed, precipitations and water levels in the Gulf of Kaliningrad. The changes in general parameters...

Presented are the characteristics of waves in the southeastern part of the Baltic Sea obtained from the results of continuous instrumental observations in 2008–2009 on the offshore oil-and-gas platform. Discussed are the conditions and prerequisites for the formation of extreme waves.

The total density of benthic organisms in the upper 10-cm horizon of sediments in the Vistula lagoon has decreased in 2 - 8-fold when the waves reach 4 mark of the Beaufort Wind Force Scale. A part of benthic organisms floats passively with re-suspended sediments in the water column, the other one migrates deeper into sediments. This fact should be...

Briefly examine centres d'action of atmosphere conception (1880) illustrated by works of the second half of 20-th century and study nova days daily weather satellite information 2002-2011.

On the base of the data of seasonal surveys (May 2003-November 2011) carried out during complex ecological monitoring of offshore oilfield Kravtsovskoye (D6), the data from automatic hydro-meteorological station MiniKrams-4 (January 2004-December 2011) seated on the offshore ice-resistant fixed platform Lukoil-Kaliningradmorneft and the data measur...

In article excitement characteristics in a southeast part of Baltic sea are presented, received by results of continuous within a year to tool supervision on sea platform D-6 in 2008-2009 the analysis of fluctuations of a sea level around a platform is carried out. Conditions of occurrence of abnormal waves are considered. It is shown that abnormal...

This article shows how dumping of sediments from an amber mining plant prevented erosion of the western shore of the Sambian Peninsula (in Kaliningrad Oblast). The average annual dynamics of coastal areas in the vicinity of the former dumping site of the amber mining plant is described. Nowadays the erosion is continuing after cessation of dumping....
