“We use these models to create reconstructions of hurricanes that have occurred in the past, and also to predict scenarios that have not yet occurred – synthetic scenarios of hurricanes.”
Dr Andrés Fernando Osorio Arias, professor at the Universidad Nacional de Colombia and Executive Director of CEMarin
It’s very rare that you get simultaneous observations of waves and currents, especially where you have such a strong tidal current.
Trygve Halsne, scientist at the Norwegian Meteorological Institute and PhD student at the University of Bergen

Using wave measurement technology to protect Vietnam’s coastal population

The Mekong Delta in Vietnam is home to over 20 million people and acts as a globally important agricultural area. The health and longevity of this important ecosystem is being threatened by rising sea levels and coastal erosion. Researchers rely on advanced wave measurement devices from Nortek to validate ocean models and provide accurate data for the development of coastal erosion defenses.The Mekong Delta encompasses the southern tip of Vietnam and is home to some of the world’s most fertile land. Over past decades, this area has faced increasing environmental pressure. Upstream

A compact underwater robot providing a safer alternative for underwater inspection, search and maintenance

Divers can face difficult and dangerous conditions when performing essential underwater inspection, search and maintenance. Now a new Remotely Operated Vehicle (ROV) from Switzerland’s Tethys Robotics is providing a much safer alternative. Find out how a Nortek DVL is being used to complete the navigation solution for this compact robot, while maintaining navigational accuracy in the most challenging underwater conditions.There are several technical challenges to operating an underwater robot in a lake or river, or offshore in areas of strong tides: the water is often cloudy or murky,

Understanding erosion of protective coastal dune systems

As sea levels continue to rise and storms intensify, countries such as the Netherlands – where a third of land is below sea level – are becoming increasingly concerned about coastal erosion.The Dutch have embraced numerous techniques to keep water at bay, but their dune systems are the primary defense against the sea. Understanding how resilient these systems are to coastal erosion is essential. The Dutch government “uses dune erosion models as the basis of their management,“ Dr Jantien Rutten, a post-doctoral researcher at Delft University of Technology (TU Delft), explains. However,

Hurricane season 2022: Colombia deploys ocean sensors for improved hurricane preparedness

With the 2022 hurricane season upon us, the importance of using science-backed solutions for hurricane preparedness is brought to the foreground. Since Colombia’s Caribbean islands were devastated by hurricanes Eta and Iota within a two-week period back in November 2020, government-funded researchers have been using wave and current data measured by Nortek’s ocean sensors to improve hurricane prediction.With a total of 14 hurricanes, 2020 was the most active Atlantic hurricane season ever. Experience of Eta and Iota prompted the authorities on the Archipelago of San Andrés, Providencia and

Safer at sea: Wave and current research improves metocean forecasts

A new study has documented the first simultaneous observations of waves and currents in Norway’s Lofoten Maelstrom – one of the world’s strongest open-ocean tidal current systems. The observations, born out of a collaboration between the Norwegian Meteorological Institute, the Norwegian Coastal Agency and Nortek AS, will help make fishing and seafaring in the area safer.The Lofoten Maelstrom is famed for its powerful waves, eddies, whirlpools and fast-flowing currents that have wrecked ships and put seafarers in grave danger for centuries. It also inspired stories such as Jules Verne’s
