Abstract

All year–round navigation in the Ob’Bay has been operating for more than ten years. In recent years it has been performed most actively at three points: the port terminals Sabetta and «Utrenniy» (on the opposite coasts in the northern part of the bay) and the oil loading terminal «Vorota Arktiki» (in the southern part of the bay, off cape Kamenny). Regular winter navigation to Sabetta began in 2013 and to cape Kamenny in 2015. In recent years, the number of vessels in November–May has already risen to about 380 per season. The winter navigation in the fast ice is performed along ice channels, which should impact on the fast ice stability. The aim of this research was to determine the influence of navigation on the fast ice distribution in the Ob’Bay in terms of climate changes. To analyze navigation impact on the fast ice distribution in the Ob’Bay, data on air temperature, ice conditions and number of vessels in the winter period were used in the work. The sum of the freezing degree days (FDD) was chosen as a parameter of winter conditions severity. The mean location of the south boundary of the flaw polynya per season was a parameter of the fast ice stability. Such an approach reduced the influence of short–term fluctuations of temperature and ice conditions. The data analysis carried out over the last 25 years has confirmed a significant influence of navigation on the fast ice distribution. It has been found that for the range from mean to mild winter conditions (an estimate using FDD), the dislocation of the flaw polynya boundary in the south direction amounted to 0.4–0.8 degrees of latitude (25–50 miles) because of winter navigation intensification. Winter conditions more severe than mean have not been recorded in the region over recent years. Therefore, such estimates were not obtained for them. The discovered changes of ice conditions are significant for the region. The transfer from fast ice to drifting ice of different types, forms and concentration will lead to the corresponding restructuring of other natural processes (water dynamics, litho-dynamic regime, etc). Subsequently the impact of hydrometeorological factors on engineering facilities can change, affecting the navigation conditions, scenarios of loading on the hydraulic structures, absolute loading values, etc. This is a factor to consider in the economic development of the region.

航行强化与气候变化共同影响Ob’Bay快冰分布的特点
Ob’bay的全年通航已经运行了十多年。近年来,它在三个地点进行得最为活跃:港口码头Sabetta和«Utrenniy»(在海湾北部的相对海岸)和«Vorota Arktiki»(在海湾南部的卡门尼角外)。2013年开始定期冬季航行到萨贝塔,2015年开始航行到卡门尼角。近年来,每年11月至5月的船只数量已经上升到380艘左右。快冰冬季航行是沿冰道进行的,这对快冰的稳定性有一定的影响。本研究的目的是从气候变化的角度来确定航行对Ob 'Bay速冻冰分布的影响。为了分析Ob’bay快冰分布对航行的影响,本研究使用了冬季的气温、冰况和船舶数量等数据。选取冻结日数(FDD)的总和作为冬季条件严重程度的参数。裂谷南边界每季节的平均位置是快速冰稳定性的一个参数。这种方法减少了温度和冰况短期波动的影响。过去25年进行的数据分析证实了航行对快冰分布的重大影响。研究发现,在平均至温和冬季条件范围内(利用FDD估计),由于冬季航行增强,南向的缺陷多冰湖边界的错位达到0.4-0.8度纬度(25-50英里)。近年来,该地区从未出现过比平均水平更恶劣的冬季天气。因此,没有对它们进行这样的估计。发现的冰况变化对该地区具有重要意义。从快冰到不同类型、形式和浓度的漂流冰的转变将导致其他自然过程(水动力学、岩石动力学等)的相应重组。随后,水文气象因素对工程设施的影响会发生变化,影响通航条件、水工构筑物加载情景、绝对加载值等。这是该地区经济发展中需要考虑的一个因素。

期刊介绍: The mission of Arctic, Antarctic, and Alpine Research (AAAR) is to advance understanding of cold region environments by publishing original scientific research from past, present and future high-latitude and mountain regions. Rapid environmental change occurring in cold regions today highlights the global importance of this research. AAAR publishes peer-reviewed interdisciplinary papers including original research papers, short communications and review articles. Many of these papers synthesize a variety of disciplines including ecology, climatology, geomorphology, glaciology, hydrology, paleoceanography, biogeochemistry, and social science. Papers may be uni- or multidisciplinary but should have interdisciplinary appeal. Special thematic issues and proceedings are encouraged. The journal receives contributions from a diverse group of international authors from academia, government agencies, and land managers. In addition the journal publishes opinion pieces, book reviews and in memoria. AAAR is associated with the Institute of Arctic and Alpine Research (INSTAAR) the oldest active research institute at the University of Colorado Boulder.
