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.

Werck. Lockheed L-1011 TriStar three-engine plane intentionally sunk in 2019. In addition to being a great attraction for divers, these sunken structures (generally ships, but also planes, military vehicles...) become artificial reefs helping in the repopulation of the underwater bottoms. This wreck is located in the Red Sea, at a depth of between 18 and 31 meters. Aqaba, Jordan.

Sargassum (Sargassum sp). Pollution, waste, plastic. The genus Sargassum is characterized by having gas vesicles known as “aerocysts” that provide them with buoyancy. Thanks to these “balls” of gas, some species of sargassum are able to remain floating on the surface of the ocean for months and the currents end up accumulating them, forming immense aggregations similar to floating islands. In the North Atlantic Ocean is the Sargasso Sea, which receives its name precisely because the presence of these gigantic aggregations on its surface is common. It serves as food, shelter and breeding area for many marine animals, such as crabs, turtles, shrimp and seabirds. At some times of the year it can appear stranded in large numbers on beaches exposed to the current and/or wind. Sometimes they are found mixed with drifting garbage such as ropes, plastics, bottles,... Playa Grande, Punta de Abona. Tenerife, Canary Islands.

Anemone and twoband anemonefish (Amphiprion bicinctus). Wreck, sunken ship. The SS THISTLEGORM is considered one of the most spectacular shipwrecks in the world for its scenic beauty. Flying the English flag, it was attacked and sunk by German bombers when heading towards the Suez Canal (October 1941). Their cargo is without a doubt one of the most peculiar that we can find under the surface of the seas: motorcycles, jeeps, military clothing, bullets, airplane wings, machine guns and a couple of locomotives and trucks.
