Reefs are vital centres of marine biodiversity. Yet, human activities like overfishing, deep-sea mining, dredging and trawling have led to their significant decline worldwide. Hence, there is an urgent need to implement efficient restoration initiatives to restore biodiversity.

A recent study published in Frontiers in Marine Science reveals an unexpected ally in this mission: fruit trees.

The study, conducted in the Dutch Wadden Sea, involved sinking felled pear trees into the sea to reconstruct reefs and enhance local marine biodiversity. 

In an unprecedented archaeological feat, the shipwreck known as "Marausa 2," which sank off Marausa, Sicily, in the late 3rd century, has been meticulously recovered from the seabed in its entirety. This marks the first instance where a Roman ship has been raised in its complete form, as opposed to being retrieved piece by piece.

Thirty shipwrecks associated with Operation Dynamo, a massive World War Two rescue operation, were surveyed by the French marine heritage agency Drassm in collaboration with Historic England.

This significant initiative, which took place between 25 September and 8 October, offers a detailed account of the wrecks' locations, characteristics and conditions, shedding light on the magnitude and human toll of this historic event.
