Multispectral multibeam echosounder backscatter data
The multibeam echosounder (MBES) is used for various purposes, and MBES systems have become the standard instrument for bathymetric determination. However, new developments mean that MBES systems are ...
Machine learning as a tool
Machine learning is currently experiencing a surge of interest. Of course, what first come to mind are self-driving cars, face recognition and internet algorithms. However, while these are great examp...
Hydrography and Oceanography: Combination of Strengths
Mathias Jonas, Secretary-General, IHO, describes the implications of the UN Decade of Ocean Science for Sustainable Development for the IHO and the hydrography sector. Proclaimed in 2017 by the United...
Uncovering the secrets of German marine munitions dumpsites
In November 2020, a team of researchers from GEOMAR and EGEOS embarked on an unusual round trip across the German Baltic Sea. Their mission was to shed light on the little-known post-war legacy of mun...
Testing and analysing uncrewed survey methods
SHOM – the French national hydrographic service – is planning to replace most of its aging seagoing assets in the near future and, in this context, a four-week sea trial took place in Brest, on th...
Exploring new horizons for ocean observation
As the informed readership of Hydro International knows, the oceans sustain the planet. And, while there are many drivers of the changes to the Earth’s climate that now pose an existential threat to...
Who is going to map the high seas?
To achieve the aggressive goals of Seabed 2030, uncrewed survey systems must be used to augment more traditional ocean mapping efforts, particularly on the high seas. In addition to providing a much-n...
Using machine learning to derive benthic habitat maps
The South African Council for Geoscience recently launched an initiative to optimize marine geophysical data collection in South African waters. The main aim of the initiative is to produce marine off...
The challenges of surveying the Faroe Islands
Remotely situated in the northern Atlantic Ocean, roughly equidistant from Scotland, Iceland and Norway, the Faroe Islands form a rugged and rocky archipelago. The cool and cloudy weather, with strong...
Data quality factors for marine UXO surveys
The detection of unexploded ordnance (UXO) in the sea is a demanding task. UXO survey data is acquired using a set of different sensors in different configurations and can span large areas. To make su...
Hydrospatial Technology: Collaboration Expanding Globally to Address Escalating Needs
Hydrospatial could be described as that portion of geospatial knowledge infrastructure that addresses the hydrosphere, and hydrospatial technologies support navigation, economic development, stability...
Introducing a Portable ASV for Extremely Shallow Waters
SWAMP (Shallow Water Autonomous Multipurpose Platform) is a new autonomous surface vehicle (ASV) whose design and development forms the foundation for an innovative class of highly modular and reconfi...
Sentinel-2 satellite-derived bathymetry in optically complex waters
Coastal areas are highly dynamic environments that are subject to diverse pressures, both anthropogenic (e.g. urban development, fishing, habitat modification) and natural (e.g. storms, erosion, flood...
Robotics and automation advance the offshore wind industry
During the life cycle of offshore wind farms (OWFs), operators must maximize the uptime of wind turbines to generate as much energy as possible. As OWFs are constructed further from the coast, mainten...
