When we think about the ocean, we often imagine its vast expanse and mystery. But few realize the importance of hydrographers in understanding our oceans and ensuring their sustainability. In a recent interview, we gained insights into the world of hydrography and marine conservation.

What is Hydrography?

At its core, hydrography involves understanding the structure and depth of the ocean floor and the water column above it. Some hydrographers produce nautical charts, essential for mariners to navigate safely, while others focus on coastal protection, offshore industries, and more. In Germany, there are about one to two thousand professionals in this field. The unique aspect of this profession is its international scope; seas aren't bound by national borders, offering hydrographers the opportunity to work globally.

Unlocking the ocean´s secrets

Thomas Dehling describes hydrography as the "key to the sea". Without it, numerous marine activities like sailing, fishing, and building offshore infrastructures are impossible. He mentions that while hydrography might not be a well-known profession, it's the linchpin for all activities at sea.

Jann Wendt, views hydrographers as key to unlocking the ocean's secrets. He contrasts terrestrial geo-data, which is mostly optical, to the acoustic world of the ocean. Hydrographers provide data that is transformed into valuable information. Despite our advanced technological era, much of our oceans remain unexplored, presenting a unique challenge for hydrographers.

Marine Conservation: Current Challenges

Marine conservation faces significant challenges, from plastic waste and ocean warming to potential threats like deep-sea mining. Jann highlighted the coming "industrialization" of our oceans, as we lean more on them for renewable energy solutions. With massive investments flowing into offshore wind farms, understanding our oceans has never been more critical.

To address these challenges, we need accurate and comprehensive data. Thomas, another hydrographer, stressed that despite covering 70% of the earth, we lack adequate information about our oceans. Hydrographers are at the forefront, utilizing advanced platforms like autonomous service vehicles, unmanned underwater vehicles, and satellite-derived bathymetry to gather data.


Technologigal advancements

The New S-100 Standard: A Game-Changer
One of the significant advancements on the horizon is the introduction of the S-100 standard, which promises to revolutionize nautical navigation. This system offers a tailor-made experience, combining various data types to provide individualized information. For example, by understanding the precise depth, currents, and water levels, ships can navigate more efficiently, reducing emissions and saving fuel. The International Maritime Organization has adopted the S-100, with a planned full implementation by the end of the decade.

Blue data economy
Jann Wendt and his team are working on a new kind of software-as-a-service solution for the maritime sector, particularly focusing on underwater data. The software addresses the complexity of handling big data from the maritime domain, given the multiple formats and types of data such as optical, video, and acoustic. Jann’s platform is especially beneficial for the offshore wind domain, assisting big energy companies in consolidating, analyzing, and distributing their data. Jann's vision also encompasses a "data economy" where surveying companies can trade their data. This would increase the value of expensive maritime data by allowing it to be reused for various purposes. He highlighted the importance of making underwater data accessible and usable for both commercial and scientific applications.

The Future of Shipping
Thomas Dehling anticipates a significant evolution in shipping, moving away from a two-dimensional approach to multi-dimensional systems. He predicts a future where the majority of buoys and navigational aids will only exist virtually, using technology to improve navigational safety. The combination of autonomous vessels with manned ones is a complex challenge that needs addressing. He also emphasized the importance of diverse data-gathering methods, such as using satellites, drones, and unmanned underwater vehicles.


The experts highlighted the increasing usage of the oceans, stressing the importance of finding a balance between economic development and environmental conservation.

Autonomous systems are seen as a crucial driver for cost reduction and innovation in ocean surveys.

Both experts appreciate the introduction of the maritime solutions topic at INTERGEO and believe it's essential to bridge the gap between the oceanic and geospatial worlds.

Both experts eagerly anticipate the event, hoping it will provide an opportunity for collaboration and knowledge sharing between the land and sea-based sectors.
