The sustainment of hydroacoustic stations is crucial for global monitoring and the verification of nuclear test-ban compliance. These stations, operating in harsh marine environments, require advanced materials to ensure their longevity/reliability. Recent developments in superhydrophobic coatings have shown great promise in enhancing the durability and sustainability of these stations....
Effective maintenance strategies and quality assurance are critical for sustaining the performance of seismic networks. The optimal mass position of seismic sensors directly impacts the quality of seismic signals, yet the diverse interfaces provided by various digitizer manufacturers complicate consistent monitoring and state of health evaluations. In Indonesia’s extensive seismic network,...
Hydroacoustic hydrophone stations of the International Monitoring System (IMS) network continuously monitor the global oceans for nuclear test explosions. The stations are equipped with hydrophones in triplet configurations placed in the SOFAR channel, where the speed of sound reaches its minimum, to detect acoustic events. Acoustic signals detected by the hydrophones are conveyed to the...
Since 2011, Bangladesh has been hosting an International Monitoring System (IMS) auxiliary seismic station, AS7 (BRDH), in Bariadhala, Chattogram. The station is located atop a hill. Erosion of the sediments and subsidence occurred on the flanks of the hills around the seismic vault and the building. As a consequence, the floor of the building began to subside as well, fractures and cracks...
