Summary

A new global Sentinel-1 synthetic aperture radar (SAR) time series data corpus has been introduced to monitor offshore wind infrastructure deployment and operation from 2016Q1 to 2025Q1. This dataset addresses the need for independent, high-temporal-resolution monitoring by providing temporally dense and semantically fine-grained information. It comprises 15,606 time series at detected infrastructure locations, totaling 14,840,637 events as analysis-ready 1D SAR backscatter profiles. The release includes these 1D SAR profiles, event-level baseline semantic labels generated by a rule-based classifier, and an expert-annotated benchmark dataset of 553 time series with 328,657 event labels. The baseline classifier achieved a macro F1 score of 0.84 and an AUC of 0.785, demonstrating temporal coherence and supporting global-scale analyses of deployment dynamics, regional patterns, vessel interactions, and operational events.

Key takeaway

For Computer Vision Engineers developing monitoring solutions for offshore wind, this new Sentinel-1 SAR dataset offers a critical resource. You can leverage its dense temporal data and expert-annotated benchmarks to develop and compare advanced time series classification methods, improving the accuracy of deployment and operational phase detection. This directly supports global-scale analyses and the identification of regional differences in infrastructure dynamics.
