TIDE — Operational Ocean and Weather Intelligence

TIDE is a browser-based client and caching layer over operational forecast and observational products - ECMWF IFS, Copernicus Marine Service, DWD ICON, and regional high-resolution models - combined with scientific tools: analytical uncertainty propagation on HF radar, Lagrangian drifter ingest with IOC quality-control flags, and native support for unstructured coastal meshes.

Browser-based, no installation. Deployed either as a managed service we operate for you, or self-hosted on your infrastructure with support for your sysadmin team. DSGVO-compliant architecture; no third-country data transfer.

Research and operational oceanography → details

For scientists and operational forecasters at hydrographic institutes, research centres, and university coastal-modelling groups. Analytical HF-radar covariance uncertainty, SCHISM / FVCOM / FESOM unstructured meshes, meteogram intercomparison across multiple models, explicit conventions, honest limitation reporting.

Search & rescue - training and planning, advisory use only → details

Leeway drift simulation (Allen 2005, 85 object types) for SAR training exercises, scenario planning, and NGO-volunteer sea-rescue preparedness. Advisory use only; operational SAR authority remains with the national rescue coordination centre.

TIDE is a client and integrator. Operational responsibility for the underlying forecasts and observations remains with the data providers. Additional datasets

• regional NWP, proprietary model chains, your own NetCDF / GRIB - can be

integrated into a deployment on request.

Deployment	Managed service (we operate) or self-hosted on your infrastructure (we support your sysadmin team).
Configuration	Data sources, feature scope, and interface branding configured per deployment.
Access control	Session cookies (HttpOnly, Secure, SameSite=Strict), 24 h rotation. No third-party analytics.
Data protection	DSGVO-compliant architecture. User identifiers hashed (HMAC-SHA256, ≥ 32-char salt); retention policies enforced server-side.
AIS relay	HMAC-SHA512/256 authenticated UDP channel for NAT'd receiver sites.
Offline mode	Progressive Web App; core workflows available without connectivity.
Frontend	Browser-based, WebGL 2.0. Runs on Android devices down to 2 GB RAM.
Backend	Go binaries, SQLite, minimal dependencies. No Kubernetes, no third-country data transfer.

Deployment-specific; quoted per customer. Scope depends on data sources, user count, feature set, branding, and hosting model. Academic, non-profit, and research-group arrangements handled case by case.

Terms of use and Auftragsverarbeitungsvertrag (DPA) available on request.
