New data release: Taiwan Strait metocean hindcast
We have a new high-resolution metocean hindcast available for the Taiwan Strait – and it’s one of the most detailed datasets we’ve produced for this region. The dataset covers 33 years of wave climate (1993–2025), 10 years of 3D hydrodynamics (2015-2024), and 25 years of winds, waves and currents during tropical cyclone events (2001–2025). What’s […]
Operational wave forecast now available for Southwest Western Australia
Oceanum has published a new operational wave forecast for the southwestern and western Australian coast, providing high-resolution wave predictions across one of Australia’s most energetic coastal environments. The dataset covers the full regional domain at 5 km resolution (112–116.5°E, 34–27°S), with two high-resolution 500 m nested grids over the Abrolhos Islands and Perth, areas of […]
Robust metocean analysis starts with obtaining accurate time series data
This first crucial step often takes much longer than expected, especially when working in an unfamiliar region. Which dataset and duration best suits the location and application? Our Metocean Data App is designed to simplify this first step in your workflow – providing rapid access to a curated catalog of validated data, worldwide. 🔗 metocean-data.app.oceanum.io […]
Supercharging THREDDS
THREDDS (Thematic Real-time Environmental Distributed Data Services) servers are crucial for optimizing access to many important gridded earth-system datasets. However, any heavy user will tell you they can exhibit annoying limitations like performance bottlenecks, configuration complexities, and stability issues when operating under high loads. We asked ourselves – can we overcome some of these limitations […]
New Zealand wave hindcast, now with 1 km nested coastal domains
We’ve published a new high-resolution wave hindcast for New Zealand on Datamesh, Oceanum.io’s environmental data platform. The dataset covers the full New Zealand domain at 5km resolution, with nine nested 1km grids over key coastal regions: Auckland, Tauranga, Hawke Bay, Waikato, Taranaki, Cook Strait, Canterbury, Otago, and Southland. The record runs hourly from 1993 to […]
A great week hosting our Chilean colleagues in New Zealand.
We brought together coastal professionals for an New Zealand Coastal Society regional event at the Beca office in Auckland, where we had excellent talks on tsunami hazard by Patricio Catalan and future coastal solutions by Patricio Winckler. Following this, we had a hands-on workshop in Raglan combining field observations with technical discussions about data science. […]
BSH operational ocean current forecasts are now available on OCEANUM.IO Datamesh
The German Federal Maritime and Hydrographic Agency (BSH) runs the HIROMB-BOOS Model (HBM) four times daily across the North and Baltic Seas — and makes the results openly available. Two resolutions are now on Datamesh: 900 m — German Bight and western Baltic Sea (25 vertical levels) 5 km — Full North and Baltic Sea […]
Wave physics, live in your browser
Waves bend around headlands, focus over reefs, shadow behind islands. The physics is elegant, but seeing it respond to your edits in real time is something else. Wavelab is a browser-based wave modelling tool that lets you adjust wave period, height and direction, reshape the seafloor, and watch refraction and diffraction patterns update live. Behind […]
Directional wave spectra from measurements with DIWASP
DIWASP-Python (Directional Wave Spectra) estimates directional wave spectra directly from sensor observations, bringing a long-standing MATLAB toolbox into an open-source Python workflow. Over 2 decades after the MATLAB toolbox release, David Johnson, one of the Oceanum team and original author of DIWASP, has finally got round to porting it to a python package with the […]
