That may be not that amazing for a shipwreck in the Øresund. According to Wikipedia, its maximum depth is 40m (130’) (https://en.wikipedia.org/wiki/Øresund), so chances are a lot of it is less deep. There also may be sampling bias, with shipwrecks in shallower water being more likely to be found, and, if the tides flow faster in deeper water, survivorship bias.

ships are less likely to wreck in deep water. Storms can sill overturn them (though if they are unstable getting to deep water is questionable). You mostly expect wrecks from hitting rocks on the bottom. Though in war time sinking happens in deep water.
