A free diver exercises dynamic apnoea below an iced platform, in the chilly salt water of the White Sea, at minus 2 degrees Celsius. Must be extremely prepared, brave and self-controlled to free-dive, holding the breath, in ambient without a fast and clear access to the surface. Reaching the underwater world, is an adventure itself since a thick layer of ice bars the passages every night, due to very low temperatures, and every day one must cut ice holes (called mainas by locals) into the ice platform. Salted water needs very low temperature to freeze. Below the ice platform, the upper layer is a melt of fresh and salt water, allowing a surprising amount of life to thrive. Location: White Sea, northern Russia.

Visualization flow of water in a sponge - Aquarius Reef Base ; Fluorescein dye is used to visualize how water is absorbed at the outside and then exhausted by a sponge.The Caribbean barrel sponge, Xestospongia muta, is a large and common member of the coral reef communities at depths greater than 10 m, and has been called the “redwood of the deep”, due to its up to 2000 year lifespan as well as its size and color. Despite its prominence, high biomass and importance to habitat complexity and reef health, very little is know about the basic biology of this massive sponge, including rates of mortality and recruitment, reproduction, growth and age. Like reef corals, this sponge is subject to bleaching and subsequent mortality.
With support from NOAA's Aquarius Reef Base at UNCW, NOAA's Coral Reef Conservation Program, and the Florida Keys National Marine Sanctuary, a research group has been monitoring populations of X. muta in the Florida Keys since 1997.

Diver in front of the largest artificial reef ever built for scuba diving (printed in 3D concrete), in the Marine Protected Area of the Agatha coast. This is the first time in the world that such a structure has been submerged. The reef is located off Cap d'Agde, 3 km from the coast, at a depth of 20 m. The module weighs 105 tonnes, measures 6.50 m high, 8 m long and 6 m wide, and offers 430 m3 of diving volume. Immersion will take place in July 2022, as part of the Recif'lab program run by the Aire Marine Protégée de la côte agathoise. An artificial reef to relieve the pressure of scuba diving on natural sites.
