The contribution towards the further study of the ocean depths’ hydrography, bathymetry, hydrology & seabed’s oceanography has been also implemented by commercial fishermen of Russia (2012).
Fishermen have started to fish with the assistance of the applied computer technology information systems to support navigation.
Almost the entire fleet of the one of the fishing organisations from Vladivostok, – has been equipped (since Y 2010) with the modern OCEAN3D navigation system.
This enabled the applied use of information technology at sea.
OCEAN3D is the computerised navigational system and, along with the traditional ECDIS (Electronic Chart Display Information System) functionality and the capacity to integrate various data from vessel electronic equipment , – in real time it is capable of to collect and correct, process and grid, render and edit , save and add, – the additional depths data and other important information related to navigation, fishing gear, seabed environment,- to the most complete and true 2D and 3D dimensional oceans’ depths’ database.
“Today we can see a model of the seabed depth up to 0.1 of a meter. OCEAN3D is able to produce the 3-D image of seabed in real time. This gives an opportunity to observe events that occur below the boat in real time and greatly helps a navigator to fish “– says the electronic department’s expert of the organisation which has already implemented OCEAN3D systems on its fleet of fishing vessels.
<<< That could be possible to fish without this kind of modern fishing navigation with such accurate maps.
However, the most “fresh” hydrographic surveys in the fishing areas, – were carried out in the 50s of the last century.
And today, a lot of those seabed’s old depths’ databases are hopelessly outdated.
To achieve the success at sea, – it is very important to have fishing ground information as accurate as possible.
And the “value” of that information may be compared to the value of “gold”.
After all, most of fish lives at greater depths.
Fishing gear is easy to lose or damage by making mistakes even for a few meters of depths.
And the new approach to commercial fishing has enhanced its efficiency and effectiveness: More Fish ~ Less Time
The introduction of modern methods of navigation have made their positive impact on all aspects of the business activity of the organisation.
Thanks to new developments.
These significantly increased earnings of employees of the organisation.
“ And, in general, this innovation helps to fish on a completely different level. ” – said the company’s management representative.
New technologies and new human resources: work with modern navigation equipment, – attracts young navigators.
This is raising the prestige of the most important profession of Primorskiy Krai.>>>

EU ~ 2009 ~ The European Marine Data and Observation Network (EMODnet)
- Phase I (2009-2013) – developed a prototype (so called ur-EMODnet) with coverage of a limited selection of sea-basins, parameters and data products at low resolution;
- Phase II (2013-2016) – aims to move from a prototype to an operational service with full coverage of all European sea-basins, a wider selection of parameters and medium rosolution data products;
- Phase III (2015-2020) – will work towards providing a seamless multi-resolution digital map of the entire seabed of European waters providing highest resolution possible in areas that have been surveyed, including topography, geology, habitats and ecosystems; accompanied by timely information on physical, chemical and biological state of the overlying water column as well as oceanographic forecasts.
BATHYMETRY @ EMODnet
Bathymetry is the information that describes the topography of the seabed, as depth from the sea surface to the seafloor. It is an essential component in understanding the dynamics of the marine environment. Safe ocean navigation relies on accurate bathymetry data, which are also essential for planning marine installations and infrastructure such as wind turbines, coastal defences, oil platforms and pipelines. Bathymetry forms the foundation of any comprehensive marine dataset; without it, the picture is incomplete.
Objectives of EMODnet Bathymetry
EMODnet Bathymetry aims to provide a single access point to bathymetric products (Digital Terrain Models) and data (survey data sets and composite DTMs) collected and managed by an increasing number of organisation from government and research scattered over Europe
Key services provided by EMODnet Bathymetry
The EMODNet Bathyemtry portal provides a range of services and functionalities to users for viewing and downloading bathymetry data products and for identifying and requesting access to the survey data sets that are used as basis input for the digital bathymetry (Digital Terrain Model). Currently the following key services and functionality are provided for users:
- Data Discovery and Access service: provides functionality to search and obtain survey data sets;
- Composite Products Discovery and Access Services: provides functionality to search and view metadata of Composite Digital Terrain Models;
- Bathymetry Viewing and Download service: provides functionality to view, browse and download digital bathymetry as Digital Terrain Models (DTMs) and obtain information about the underlying data sets used to compile the DTMs.
The following steps are taken to make the Bathymetry portal fully operational:
- Establishment of an inventory of available bathymetric data sets acquired and managed by relevant research institutes, monitoring authorities, and national hydrographic services;
- Development of regional Digital Terrain Models (DTM) using selected survey data sets and processing these by regional teams using a common methodology for QA – QC;
- Development of an overall EMODnet DTM with a gridsize of ⅛*⅛ arc minutes by integrating the regional DTMs and loading this into a geospatial database.
The partners of EMODnet Bathymetry combine expertise and experiences of collecting, processing, and managing of bathymetric data together with expertise in distributed data infrastructure development and operation and providing of discovery, access and viewing services following INSPIRE implementation rules and international standards (ISO, OGC).
For the purpose of collecting hydrographic data sets, such as multibeam surveys from scientific cruises, several types of hydrographic data providers were engaged.
Digital Terrain Model (DTM) product development
Digital Terrain Model (DTM) are based on 3 types of bathymetric data sources.
- Bathymetric surveys, such as single and multibeam surveys, echosoundings and even historic leadline soundings. These data sets are most preferred as data source because of their high resolution.
- Composite data sets, giving a gridded bathymetry. In practice it appears that Hydrographic Offices (HO’s) do not want or can not deliver primary surveys but composite data sets from the Digital Terrain Models that they maintain themselves for producing and maintaining their nautical charts following international IHO procedures.
- GEBCO 30” gridded data. GEBCO 2014 is used by the EMODNet project to complete area coverage in case there are no survey data or composite data sets available to the partners.
Improvements in the current development Phase II (2013-2016)
- Higher resolution digital terrain model (⅛ rather than ¼ of an arc minute);
- Fuller coverage (now includes Baltic, Black Sea and Norwegian Sea).
USA ~ 2015 ~ NOAA COASTs SURVEYs
Mapping is the foundation of ocean exploration and marine spatial planning. In its mission to explore and broaden our knowledge of the oceans, the NOAA ShipOkeanos Explorer has collected high-resolution multibeam data as an integral part of its operations around the globe. Since 2013, the Office of Coast Survey has collaborated with the Okeanos Explorer during their expeditions, to improve hydrographic acquisition and processing methods and expand multibeam coverage in the Gulf of Mexico and Atlantic Ocean. The resulting bathymetry has supported a diverse array of oceanic research and contributed to the protection of ecologically critical habitats in U.S. waters.
A new initiative between the Office of Ocean Exploration and Research and Coast Survey has opened the door to further maximizing the data’s usefulness. In alignment with NOAA’s integrated ocean and coastal mapping program’s philosophy of “map once, use many times,” this pilot project will integrate Okeanos Explorermultibeam data from the Gulf of Mexico into NOAA’s nautical chart update pipeline, and will expand in the future to incorporate data from the Atlantic and Pacific Oceans… https://noaacoastsurvey.wordpress.com/2015/03/18/explore-once-use-many-times/
