#Knowledge of our #waters can help us make informed #decisions. This applies to hydrographic information such as the shape of the seabed. It also applies to #oceanographic #data and #measurements. The world's oceans are a key element of the global ecosystem. They are rich in #biodiversity. Describing and monitoring them is essential for the functioning of #marine #ecosystems and thus for the protection and sustainable use of the oceans. In the latest issue of The International Hydrographic Review (#IHR, https://ihr.iho.int), Alex David Rogers from Ocean Census and Eva Ramirez-Llodra from REV Ocean give an excellent historical perspective of the activities to discover the diversity of species in the #deep #sea over the last hundred years. The authors show that as human impact increases, knowledge of the distribution of life must be constantly improved through further deep-sea #exploration of marine ecosystems. 📌 Please click here to read and download this article: https://lnkd.in/d93ZHX2P 📌 You can view the full issue of IHR and find other interesting articles and notes on hydrography and other topics at https://lnkd.in/dCEgN7by 💡 Are you interested in contributing to IHR, an international scientific journal that publishes open access peer-reviewed papers on all aspects of hydrography and related topics?

108 new underwater features were named during the recent meeting of the IHO-IOC GEBCO Sub-Committee on Undersea Feature Names SCUFN in Jeju, Republic of Korea. This included Ngerchelechuus Seamount, a big seamount with a total relief of 3518 m (summit depth 1637 m), which has been surveyed on several occasions between 1995 and 2020 by JAMSTEC: Japan Agency for Marine-Earth Science and Technology. This name was submitted by the Territory and Boundary Task Force, of the Office of the President of the Republic of Palau. Members of the sub-committee also made progress with the plan to use an alpha-numerical identifier to name undersea features. The objective is to help address more rapidly the large volume of naming submissions received each year and decrease discussions on proposals in disputed areas or on dual names for the same feature, which result in hundreds of features being omitted from the GEBCO - General Bathymetric Chart of the Oceans Gazetteer. When members cannot agree on a name, information about the feature, including its size, shape, height or location are not registered either. To avoid losing valuable information on seabed topography, this proposal to create a single, universally recognized alphanumerical code would ensure that at least data on the feature is registered. Members of SCUFN have liaised with the founder of the Working Group on Star Names of the International Astronomical Union for benchmarking best practices, rules of procedures and nomenclatures. During this meeting, they also approved the Terms of Reference and establishment of the new SCUFN Sub-Group Naming 2030, which aims to prepare SCUFN to face future challenges. New members announced their intention to join and contribute to this sub-group, including subject matter experts in data modelling (Marine Regions, NOAA: National Oceanic & Atmospheric Administration and Canada). This 37th meeting of SCUFN was hosted jointly by the Korea Institute of Geoscience and Mineral Resources (KIGAM) and the Korea Hydrographic and Oceanographic Agency (KHOA ROK). It was chaired by Dr Yasuhiko Ohara from the Japan Hydrographic and Oceanographic Department. The IHO Secretariat was represented by Assistant Director Yves Guillam (SCUFN Secretary).  

Happy #WorldHydrographyDay! Listen to IHO Secretary General Dr Mathias Jonas as he discusses #hydrography, the shift to a #data-centric approach, cooperation with data providers and more. 

This #WorldHydrographyDay, we would like to celebrate what people across the globe are doing to enhance #safety, efficiency and #sustainability in #marine activities. Read on to learn about the #digitaltwin of navigable waters, the S-100 framework and some of the projects around the world. https://lnkd.in/dia3TEGn KHOA ROK Fisheries and Oceans Canada / Pêches et Océans Canada Sjöfartsverket

Professionalism, dedication, profound knowledge, expertise, kindness, these are a few of the words used to describe the winner of the new Ex Abyssis ad Alta – IHO Award for Hydrographic Excellence. As part of World #Hydrography Day, the IHO announces Mr. Yves GUILLAM as the recipient of this year’s award. The full article discusses his long career and what some of the IHO Member States have to say about him. We would be interested in hearing what you have to say about him. 📌 https://lnkd.in/dbEzq_gs

The global #hydrographic community has just got bigger with the 💯th country joining the IHO! The new Member State is the only country in the world straddling the 4 #hemispheres, spread over 3,441,810 km2 of #ocean. Read on to hear about some of their ocean priorities, including carrying out obligations under the #SOLAS Convention, #fisheries 🐟management, and #economic growth.

[World Oceans Day] 𝐔𝐧𝐝𝐞𝐫𝐬𝐭𝐚𝐧𝐝𝐢𝐧𝐠 𝐬𝐞𝐚-𝐥𝐞𝐯𝐞𝐥 𝐫𝐢𝐬𝐞: 𝐢𝐦𝐩𝐫𝐨𝐯𝐢𝐧𝐠 𝐩𝐫𝐞𝐝𝐢𝐜𝐭𝐢𝐨𝐧𝐬 𝐭𝐡𝐫𝐨𝐮𝐠𝐡 𝐬𝐭𝐮𝐝𝐲𝐢𝐧𝐠 𝐭𝐡𝐞 𝐬𝐡𝐚𝐩𝐞 𝐨𝐟 𝐭𝐡𝐞 𝐬𝐞𝐚𝐛𝐞𝐝 Petermann #glacier in Greenland recently lost nearly 40% of its floating ice tongue, while just a few kilometres away, Ryder Glacier had been stable for decades. With the melting of marine glaciers draining into the #ocean constituting one of the largest uncertainties in projections of global #sealevel rise, a team of ocean mappers decided to look deeper into what processes could be influencing the formation and melting of glaciers. They discovered a surprising connection between the shape of the seabed and the size of glaciers. As part of #WorldOceanDay, this video looks at how better bathymetric #data can help improve sea-level rise predictions.

Cooperation between the IHO and the #EuropeanUnion was reinforced last week. The IHO-EU Network Working Group (IENWG) met in Svendborg, Denmark on 29 May 2024, hosted by the Danish Geodata Agency. The objective was to strengthen the relationship between the IHO and EU and develop a strategy for the areas of common interest, such as moving forwards with #technology in support of smart #marine #navigation (through the S-100 standard for example), #Capacity Building and #Data Collection. Attendees followed on with the European #Maritime Days (EMD) organized by the European Commission / City of Svendborg / Danish Maritime Authority on 30 and 31 May 2024 in Svendborg. The IHO together with its Seabed 2030 project, contributed to the booth hosted by EMODnet. The IENWG meeting was chaired by Mr Pierre Yves Dupuy (France) and attended by 17 participants representing 9 IHO European Member States and the European Commission – DG Mare. IHO Director Luigi Sinapi represented the International Hydrographic Organization (IHO) Secretariat. SHOM

The latest issue of the International Hydrographic Review is out! ⚓️⚓️⚓️ Knowledge of our #seas and #oceans can help to make informed #decisions and is key to #protecting and #sustainably using them. To fill #gaps in #ocean #data we need different perspectives. This issue covers some of these different perspectives and includes articles on: 🌊#oceanography with the exploration of deep-sea #biodiversity; 🌊#geodesy with the presentation of a novel cargo ship-based #GNSS network analysing sea surface heights for #tsunami detection; 🌊 #geology with #AI-based #boulder detection in #sonar data; and of course #hydrography with contributions on #crowdsourcing #water #depth data.

The IHO has published the first “Satellite-Derived Bathymetry Best Practice Guide”. The new document provides an overview of methods and guidance to #map shallow coastal environments. #Satellite-Derived #Bathymetry (SDB) is the calculation of shallow water depth from active or passive satellite sensors. It allows users to obtain shallow water bathymetry data at a lower cost and can be used for areas that are physically inaccessible or difficult to survey by other means. This publication has been produced by the IHO’s Satellite Derived Bathymetry Project Team, which is chaired by Knut Hartmann of EOMAP . https://lnkd.in/dQHfaDjU
