Abstract:

In modern ocean exploration, forward-looking sonar (FLS) provides real-time 2D imaging of the seabed ahead, but its detection range is relatively limited. Conversely, side-scan sonar (SSS) enables large-scale imaging of the seabed during movement but struggles to effectively image areas directly beneath the sensor. Integrating FLS and SSS offers a promising solution by leveraging their complementary strengths to achieve comprehensive seabed mapping. However, no prior research has explored this fusion approach. This paper presents a novel method for FLS and SSS fusion mapping. Firstly, a novel

Abstract:

Over the last few centuries, mapping the ocean seabed has been a major challenge for marine geoscientists. Knowledge of seabed bathymetry and morphology has significantly impacted our understanding of our planet dynamics. The history and scientific trends of seabed mapping can be assessed by data mining prior studies. Here, we have mined the scientific literature using the keyword “seabed mapping” to investigate and provide the evolution of mapping methods and emphasize the main trends and challenges over the last 90 years. An increase in related scientific production was observed in the begin

Abstract:

Seabed mapping has become vital for effective management of marine resources. An important role in moving towards ecosystem based management is played by the defining and understanding of the relationships among marine habitat characteristics, species distribution and human activities. Mapping seabed characteristics by means of remote acoustic sensing, using seabed seismic profiling, sidescan sonar, or echo-sounder based classification systems, is becoming of increasing importance. This paper gives a brief overview of existing marine habitat mapping technologies and their recent developments.

Abstract:

The deep seabed is composed of heterogeneous ecosystems, containing diverse habitats for marine life. Consequently, understanding the geological and ecological characteristics of the seabed’s features is a key step for many applications. The majority of approaches commonly use optical and acoustic sensors to address these tasks; however, each sensor has limitations associated with the underwater environment. This paper presents a survey of the main techniques and trends related to seabed characterization, highlighting approaches in three tasks: classification, detection, and segmentation. The

Abstract A wide range of seabed-mapping technologies is reviewed in respect to their effectiveness in discriminating benthic habitats at different spatial scales. Of the seabed attributes considered important in controlling the benthic community of marine sands and gravel, sediment grain size, porosity or shear strength, and sediment dynamics were highlighted as the most important. Whilst no one mapping system can quantify all these attributes at the same time, some may be estimated by skilful interpretation of the remotely sensed data.

The scientific achievements of Paul Langevin are numerous and far-reaching. In the 150th anniversary of his birth, we look at one of his early contributions, forged in the heat and pressure of World War I. For most historians of science, Paul Langevin is the creator of sonars, and this opened a totally new window onto our world. In their first century of use, sonars quickly spread throughout the world, revealing the depths of the oceans, the complexities of marine life and the richness of oceanography. In the last decades, their capabilities were greatly augmented with the use of new materials

High quality seabed data are fundamental to a wide range of engineering, management and science research applications stretching from shallow-water coastal environments, across the shelf and out on to the abyssal sea floor. Coastal applications require high-resolution, quality bathymetry data to support models for understanding currents and waves, sediment transport and erosion, hazard and risk assessment as well as ensuring safe navigation and informing development associated with infrastructure and commercial projects. Combined with other seabed data types, the information supports research

Abstract:

The efficient investigation of fishery resources is critical for rapidly understanding the effects of abrupt environmental changes. Seabed imagery has been used extensively for resource assessment in scallop fisheries in the Sea of Okhotsk, Hokkaido, Japan. However, the potential of these images for the broader investigation of epibenthos remains unclear. In this paper, we propose an automatic detection method for epibenthos from seabed images using deep learning, specifically Mask R-CNN and Mask2Former models. We focus on four species: Asterias amurensis, Distolasterias nipon, Halocynthia aur

The similarity index (SI), computed from the singular value decomposition of seabed-echo envelopes recorded in Chirp seismic data, was tested in mapping the acoustic diversity of the seabed in Suyong Bay, Busan, Korea. Rocky bottom is characterized by low SI values, indicating acoustic heterogeneity, and sedimentary seabed by high SI values, also i

Abstract:

Abstract The seabed can be classified using data from vertical, split-beam echosounders. This was demonstrated recently using a model parameterized with acoustic estimates of slope, roughness, normal-incidence backscattering strength, and variation of backscattering strength by frequency and incidence angle. These seabed classifications were interpreted and validated using published surficial geology maps, but the acoustic data indicated greater spatial variability. Here, classifications of sediment grain or feature size are ascribed to areas ∼10 m2. First, images of the seabed in the study ar

Abstract:

Monitoring of coastal areas by remote sensing is an important issue. The interest of using an unmixing method to determine the seabed composition from hyperspectral aerial images of coastal areas is investigated. Unmixing provides both seabed abundances and endmember reflectances. A sub-surface mixing model is presented, based on a recently proposed oceanic radiative transfer model that accounts for seabed adjacency effects in the water column. Two original non-negative matrix factorization ( N M F )-based unmixing algorithms, referred to as W A D J U M (Water ADJacency UnMixing) and W U M (Wa

Abstract:

Calibrated acoustic backscattering measurements using 12, 38 and 120 kHz were collected over depths of 30–230 m, together with benthic epi- and in-fauna, sediments, photographs and video data. Each acoustic ping was envelope detected and digitized by echo sounder to include both the first and second echoes, and specifically designed software removed signal biases. A reference set of distinct habitat types at different depths was established, and a simple classification of the seabed combined both biological and geological attributes. Four seabed types were identified as having broad biological

Abstract:

Multi-beam sounding technology can provide higher spatial resolution than single-beam sounding by transmitting fan-shaped acoustic signals from the transducer of a survey ship along the normal plane of the survey line to measure the sea depth. It is of great significance to study the line design scheme of multi-beam sounding for uneven seabed topography to improve the efficiency of underwater terrain mapping. This paper mainly studies the optimization of multi-beam sounding line under ideal slope. Firstly, a single angle model of ideal slope is established, and the flat seabed overlap ratio fo

Abstract:

The development of multibeam echosounders (MBES) as a seabed mapping tool has resulted in the widespread uptake of backscatter intensity as an indicator of seabed substrate properties. Though increasingly common, the lack of standard calibration and the characteristics of individual sonars generally produce backscatter measurements that are relative to a given survey, presenting major challenges for seabed mapping in areas that comprise multiple MBES surveys. Here, we explore methods for backscatter dataset harmonization that leverage areas of mutual overlap between surveys for relative statis

Abstract:

Reyna Bay, an artificial bay on the northern Romanian Black Sea coast near Constanța, underwent significant modifications between 2015 and 2016 to protect against erosion. Reinforced embankments and submerged spur dikes were installed to stabilize the shoreline, while newly added sand with a high shell fragment content can mitigate sediment loss. This study focuses on habitat mapping in Reyna Bay, covering an area of 400 m in width and extending up to a kilometre beyond the bay. Habitat mapping is crucial for understanding the distribution of marine habitats, especially in areas where coastal
