Slight bleached knots, Pre plucked, natural hairline, Glueless, Baby Hair Around ![]() Project partners also hope to “further unlock the potential of sponge grounds for innovative blue biotechnology namely towards drug discovery and tissue engineering.Long Hair Wigs, Medium Hair Wigs, Short Hair WigsĪverage Size (Head circumference : 54cm-58cm ) The ongoing SponGES (Deep-sea Sponge Grounds Ecosystems of the North Atlantic: an integrated approach towards their preservation and sustainable exploitation) project that contributed to the study “will improve predictive capacities by quantifying threats related to fishing, climate change, and local disturbances,” as noted on CORDIS. “Therefore, the quantification of the dark silica provided in this study does not only support that the silicon inputs and outputs of the marine silicon cycle are in equilibrium, but it also introduces the idea for further investigations that the functional connections between the carbon and silicon cycles in the ocean are not as straightforward as previously thought.” This refers to “siliceous skeletons produced in disconnection from the photosynthesis and the consumption of CO2, often in marine environments lacking sunlight where diatoms cannot even survive,” as explained in the press release. In addition, the scientists have pointed to the notion of dark silica. This finding increases about 28% the size of the biological silicon sink in the ocean, which had previously been calculated considering only the skeletons of diatoms.” Dark silica “More specifically, it was discovered that sponges are responsible for burying approximately 48 million tons of silicon every year through the microscopic pieces that make their siliceous skeletons. “As glaciers and polar caps continue to thaw, it is necessary to find out whether other important biological sinks of dissolved silicon occur in the ocean, in addition to the burying of diatom skeletons,” as reported in a press release on the project website. How fast this cycle turns and how much silica is supplied for diatom growth will have implications for warming or cooling our climate. The dissolved silica is recycled and eventually upwelled for use again in the sunlit (euphotic) zone. The sinking of carbon and silica out of the surface ocean helps keep this atmospheric greenhouse gas in check. ![]() When they die, diatoms typically sink to the seafloor, taking carbon out of the surface waters and locking it into sediments below. The findings were published in the journal ‘Nature Geoscience’.ĭuring photosynthesis, diatoms turn CO2 into organic carbon and generate oxygen in the process. ![]() ![]() Partially supported by the EU-funded SponGES project, a team of scientists has shown that most of the silicon in the oceans comes from sea sponges, and not just from diatoms as previously thought. Dissolved silicon is necessary for the growth of many species of diatoms, which are among the key organisms involved in removing CO2 from the Earth’s atmosphere. Silica forms the skeleton structures of a variety of aquatic plankton, including many diatoms, photosynthetic algae found in marine and freshwater ecosystems. The second-most abundant element in the Earth’s crust after oxygen, and part of sediments, minerals and rocks in the oceans, silicon is also found in dissolved form in seawater. According to some estimates, over a third of CO2 – one of the primary greenhouse gases – is absorbed by the oceans. CO2 emissions don’t just affect our atmosphere.
