Abstract

The removal of ordnance and ammunition followed by high levels of impulsive noise is implemented yearly in the Lithuanian area of the Baltic Sea. During the international naval exercise Open Spirit (Summer 2013), an acoustical survey (using submersible cable hydrophone) was conducted in order to measure the underwater impulsive noise levels produced by controlled detonation and to assess their potential ecological impacts. The findings indicate a high noise energy level of explosions having a particularly small weight of charges, reaching up to 190 dB (in low-frequency bands) and theoretical estimations of the initial shock wave of 276 dB.

立陶宛波罗的海历史武器爆炸产生的水下噪音:对海洋生物的潜在生态影响

在波罗的海立陶宛地区，每年都要清除武器和弹药，然后产生高水平的脉冲噪声。在国际海军演习“开放精神”(2013年夏季)期间，为了测量受控爆炸产生的水下脉冲噪声水平并评估其潜在的生态影响，进行了声学调查(使用潜水电缆水听器)。研究结果表明，爆炸的高噪声能量水平具有特别小的装药重量，达到190 dB(在低频波段)，理论估计初始冲击波为276 dB。

期刊介绍： BALTICA is an international periodical journal on Earth sciences devoted to the Baltic countries region and the Baltic Sea problems. This edition as a Yearbook is established in 1961 by initiative of Academician Vytautas Gudelis. Since 1993, an Editor-in-Chief of the journal became Academician Algimantas Grigelis. BALTICA is published biannually (in June and December) in cooperation with geoscientists of the circum-Baltic States. BALTICA is publishing original peer-reviewed papers of international interests on various Earth sciences issues. The particular emphasis is given to Quaternary geology, climate changes and development of ecosystems, palaeogeography, environmental geology, as well as stratigraphy, tectonics, sedimentology and surface processes with relevance to the geological history of the Baltic Sea and land areas. Journal emphasizes modern techniques, methodology and standards. The journal structure comprises original articles, short reviews, information, bibliography.
