The new-generation geohydroacoustic buoy prototype is designed for simultaneous acquisition of acoustic, hydroacoustic, and seismoacoustic data in various environmental conditions, including onshore and offshore boreholes, yet is specifically targeted for operation in Arctic seas as an element of the distributed ice-class drifting antennas. Modular structure of the geohydroacoustic ice buoy incorporates the advanced data logger and a combination of sensors: vector-scalar hydroacoustic (0.01-2.5 kHz) accelerometer, broadband molecular-electronic (0.03-50 Hz) velocimeter, as well as optional hydrophones. The distinguishing feature of the geohydroacoustic buoy is its low power consumption responsible for consistent autonomous operation of the entire measurement system for at least one week. Results of continuous laboratory tests carried out at the geophysical observatory of the Geophysical Survey of the Russian Academy of Sciences (GS RAS) in Obninsk are presented. It has been confirmed via comparative analysis of recorded time series featuring microseismic noise and teleseismic earthquakes that the prototype well meets the high standards of modern seismology.
新一代的水声地球物理浮标原型旨在各种环境条件下（包括陆上和海上钻孔）同时采集声学、水声学和地震声学数据，特别是作为分布式冰级漂流天线的一个元素，用于北极海域的作业。水声地球物理冰浮标采用模块化结构，内置先进的数据记录仪和多种传感器：矢量标量水声学（0.01-2.5 kHz）加速度计、宽带分子电子（0.03-50 Hz）速度计以及可选的水听器。水声地球物理浮标具有功耗低的特点，可确保整个测量系统持续自主运行至少一周。本文介绍了在俄罗斯科学院地球物理研究所（GS RAS）在奥布宁斯克的地球物理观测站进行的连续实验室测试的结果。通过对微震噪声和远震地震记录的时间序列进行比较分析，证实该原型满足现代地震学的高标准要求。
