Can anyone hint me at some websites where I can explore the Sentinel-1 images directly?

Seems like https://dataspace.copernicus.eu/browser/ is the place to go.

Looks like you need to register for a (free) account, though.

SentinelHub EO Browser is, as the name suggests, a browser based explorer of Sentinel imagery

You can even download subsets of the data for free (requires login though). It's one of the simplest ways to get started exploring Sentinel imagery IMHO

In short, 72–76% of the world’s industrial fishing, and 21–30% of transport and energy, vessel activity are missing from public tracking systems. The actual article from Nature, in open access: https://www.nature.com/articles/s41586-023-06825-8

But can we trust the hallucinations of the “AI”?

We're not talking about putting the pictures into ChatGPT here.

Anyway, from their tests using standard CNN practices: "Our best model achieved on the test set an F1 score of 0.97 (accuracy = 97.5%) for the classification task and a R2 score of 0.84 (RMSE = 21.9 m, or about 1 image pixel) for the length-estimation task."

The Planetary Computer from Microsoft has an explore tool, which includes Sentinel-1 at any time and location, rendered on-the-fly. Free open access. No account required.
