Underwater communication systems have drawn the attention of the research community in the last 15 years. This growing interest can largely be attributed to new civil and military applications enabled by large-scale networks of underwater devices (e.g., underwater static sensors, unmanned autonomous vehicles (AUVs), and autonomous robots), which can retrieve information from the aquatic and mar...

Underwater acoustic networks have the potential to support a wide variety of applications from facilitating communication between autonomous underwater vehicles to supporting the remote monitoring of underwater mining equipment or environmental conditions [1]. Even though underwater acoustics has been studied for many years, and communications technologies exist for underwater scenarios, intere...

Underwater Wireless Sensor Networks (UWSNs) provide a new opportunities to examine and predict the activities of aquatic environments. Some applications such as target tracking , disaster prevention etc where sensed data is worthless without any location information. Localization is the process of estimating the location of each node in a sensor network. In underwater sensor networks (UWSNs) de...

Underwater machine vision attracts more attention, but the terrible quality prohibits it from a wide range of applications. There exist many algorithms to solve this problem, but the real-time and adaptive method is frequently deficient. In this paper, based on filtering and Generative Adversarial Networks (GANs), two approaches are proposed for the aforementioned issue, i.e., a filtering-based...

Autonomous Underwater Vehicles (AUVs) have widely deployed in marine investigation and ocean exploration in recent years. As the fundamental information, their position information is not only for data validity but also for many real-world applications. Therefore, it is critical for the AUV to have the underwater localization capability. This report is mainly devoted to outline the recent advan...

Underwater acoustic communication and networks have attracted significant attention in recent years, with applications ranging from ocean monitoring to off-shore sensor control, and port surveillance. Experimental data are required to test and develop effective underwater networking protocols before underwater networks can be successfully deployed for real world applications. Unfortunately, the...

Underwater wireless sensor networks (UWSNs) are the enabling technology for various underwater applications, and the interest in UWSNs is growing. Applications of underwater sensing range from oil industry to aquaculture, and include instrument monitoring, pollution control, climate recording, prediction of natural disturbances, search and survey missions. Location information is important for ...

This paper presents a vision based tracking system for routine underwater pipeline or cable inspection for autonomous underwater vehicles (AUV’s). The objective of this research paper is to investigate the issues of pipeline detection, including pose and orientation measurements in underwater environments. The proposed visual tracking system used an active contour method to track underwater obj...

Underwater sensor nodes will find applications in oceanographic data collection, pollution monitoring, offshore exploration, disaster prevention, assisted navigation and tactical surveillance applications. Moreover, unmanned or autonomous underwater vehicles (UUVs, AUVs), equipped with sensors, will enable the exploration of natural undersea resources and gathering of scientific data in collabo...

Abstract This study investigates stagnation conditions of the Pensilungpa glacier, western Himalaya. Multiple glacier parameters (length, area, debris extent and thickness, snowline altitude (SLA), velocity, downwasting ice cliffs) were studied using field measurements (2016–18), high-resolution imagery from GoogleEarth (2013–17) spaceborne Landsat, ASTER SRTM data (1993–2017) to comprehend gla...
