Tiny, shrimp-like crustaceans, lanternfish, squid, gelatinous drifters, transparent hunters, a multitude of fish, and many more. Together, they ascend towards the surface in immense numbers, coming with the protection of darkness to feed in the richer waters above. Then, before dawn, they sink once more into the dimness of the depths. This happens every night in oceans around the world, yet most people have never heard of it.

The decision follows years of campaigning by the Hurghada Environmental Protection and Conservation Association (HEPCA), whose efforts helped bring international attention to the destruction caused by the shark-fin trade. The organisation’s work culminated in a decree that finally gave legal force to protections that had existed largely on paper.

The Dive Rite Nomad Mini Sidemount System is a streamlined sidemount buoyancy compensator developed for divers seeking a compact configuration with reduced bulk. Designed around the requirements of warm-water diving and travel, the system is intended primarily for use with aluminium 80 cu ft cylinders and provides 25 lb (11.3 kg) of lift. Its low-profile wing is based on the Nomad platform but scaled down to minimise drag and improve packing efficiency.

A ghost-net removal mission in the Strait of Sicily has produced what may be the first underwater footage captured by divers of an adult great white shark in the Mediterranean Sea.

The encounter came about during a conservation expedition organised by Healthy Seas in partnership with Ghost Diving and SDSS (The Society for Documentation of Submerged Sites). The team was working on an offshore shipwreck between Sicily and Tunisia, removing abandoned fishing nets that continue to trap and kill marine life.

The US Navy has confirmed the identity of a World War II submarine wreck discovered off the coast of Matsuwa Island in the Kuril Islands, bringing closure to a mystery that has endured for more than eight decades.

The wreck has been identified as USS Herring (SS-233), a Gato-class submarine lost on 1 June 1944 during combat operations against Japanese forces in the northern Pacific. All 83 crew members aboard were lost.

Italian archaeologists have begun detailed study and recovery operations on a 5th to 4th-century BC shipwreck discovered off the coast of Calabria, southern Italy. The site contains a cargo of more than 300 amphorae and could yield new insights into ancient trade routes linking the Greek colonies of Magna Graecia with the wider Mediterranean world.

Beneath the calm surface of the ocean lies a world of immense geological energy—continents drifting apart, mountains rising, crust vanishing into the mantle. 

The ocean conceals a restless planet.

Earth’s broken shell

The outer surface of the Earth is not a single unbroken shell. It is divided into enormous pieces called tectonic plates. These plates drift atop softer, slowly flowing rock deep within the planet. Some move only a few centimetres each year, about as fast as fingernails grow.

Every day, divers capture images of fish living naturally on coral reefs, over sandy bottoms, in kelp forests, estuaries, caves, and the open sea. These photographs are far more than souvenirs or artistic images. Increasingly, they are valuable scientific records, documenting marine biodiversity at a time when aquatic ecosystems are changing rapidly.
