Funded Opportunities for Training & Sea Survey Experience
As part of its ongoing commitment to strengthening hydrographic capacity worldwide, the IHO is pleased to share that several fully-funded opportunities for training and hands-on survey experience are currently open for applications, including a call to participate in a trans-Atlantic hydrographic survey.
Why CSB ?
Participating in the CSB Initiative benefits both those collecting the data and the communities of data users. These data contribute to increasing our knowledge, information which supports local regional and global initiatives in favour of the sustainable use of the oceans. They can also contribute to improved knowledge of seabed topography and better bathymetric maps or hydrographic charts in previously uncharted areas or areas lacking accurate data. This in turn can help avoid groundings and make navigation safer for all.
From ocean mapping to Argo floats: how are we learning about the changing ocean?
Better ocean data can be used to inform a variety of decisions from storm preparedness to seaweed farming. As part of the Monaco Ocean Week, the IHO hosted an event which provided an overview of some of the work being done to increase our knowledge of the ocean, from Prince Albert I of Monaco’s original idea of ocean mapping to the Argo programme, an exciting, global multidisciplinary project.

Importance of Hydrography
Definition of Hydrography Hydrography is the branch of applied sciences which deals with the measurement and description of the physical features of oceans, seas, coastal areas, lakes and rivers, as well as with the prediction of their change over time, for the primary purpose of safety of navigation and in support of all other marine activities, including economic development, security and defence, scientific research, and environmental protection. In addition to supporting safe and efficient navigation of ships, hydrography underpins almost every other activity associated with the sea, including: - resource exploitation - fishing, minerals,.. - environmental protection and management - maritime boundary delimitation - national marine spatial data infrastructures - recreational boating - maritime defence and security - tsunami flood and inundation modelling - coastal zone management - tourism - marine science
At Sea with the EWH Project: Member State Participants Gain Hydrographic Survey Experience
