A new solution that uses seaweed to help improve water quality in the Great Barrier Reef is advancing to a new level of research interest, with trials on the water starting next month. Yes.
Researchers will try to see if natural seaweeds that are planted in important areas are more effective at removing contaminants from the water.
The Australian Seaweed Institute has developed a natural solution, which was first recognized by the World Economic Forum as a global approach to protecting oceans.
What is the effect of Water Reef?
Every year, thousands of metric tons of essential nutrients, such as nitrogen and phosphorus from plants, run out of land and out to the Reef. This can cause harmful algae blooms, reducing inflammation and inflammation.
The effect of rising green gas emissions is also making the water more acidic when the ocean is exposed to high levels of carbon dioxide – threatening the lives of corals. and their marine life.
How does limu help?
Algae have shown their ability to act as a good biofilter, preventing pollution by capturing and breaking down these harmful pollutants. Algae are good because they absorb carbon, nitrogen and phosphorus from the water to help with growth and provide a habitat for marine life.
Both activities can significantly improve water quality and marine life, improving conditions for the entire Reef ecosystem.
What are the findings so far?
By 2020, the first stage of the development of algae biofilters, the design phase, has identified three natural algae species that produce high levels of nutrients – Asparagopsis taxiformis, Sargassum spp and Gracilaria edulis. . The researchers also looked for possible ways to grow these species and carried out the experiments in the box.
This project is a joint venture between the Australian Seaweed Institute and Central Queensland University. They found that seaweed biofilters can remove thousands of metric tons of dissolved inorganic nitrogen – a major Reef pollutant – from water each year.
Under the second stage of the research, small seaweed “bio-pods” will be placed in an estuarine area. These plants will be monitored to see how well they grow and how much nitrogen they contain. The researchers will compare the performance of biofilters at different locations across the Reef.
The remaining water from the food industry promotes seaweed production
