Relying on insights from Scientific Research and Publications
Supported by research
Rhodoliths and maerl are widely recognized as vital components of the ocean's carbon sink, with extensive research highlighting their role in sequestering atmospheric CO2 through calcification processes. This body of research provides valuable insights into the distribution of Rhodolith and Maerl habitats, offering a foundation for understanding where these ecosystems thrive and how they interact with their environments.
At Blusink, we leverage this knowledge to identify suitable deployment sites, assess how our technology will perform in varying water conditions, and refine our approach for optimal effectiveness.
While significant progress has been made, many gaps remain in understanding the full extent of Rhodolith and Maerl habitats and their potential for large-scale carbon capture. By combining existing research with our own monitoring efforts, we aim to advance scientific understanding and contribute to the sustainable utilisation of these natural carbon sinks.
Below we have compiled some of the leading research articles regarding Rhodolith/Maerl habitats. These are independently published articles which Blusink has no affiliation or involvement in.
“Pink power”—the importance of coralline algal beds in the oceanic carbon cycle
This article discusses how coralline algal beds, dominated by pink rhodoliths and maerl, serve as essential oceanic carbon sinks. Covering an estimated 4.12 million km² globally—far surpassing other macroalgal habitats—they exhibit remarkable carbon uptake, with productivity rates of 281–347 g C m² per day.
Reviews and Synthesis: Calculating the global contribution of coralline algae to total carbon burial
This article provides a comprehensive analysis of the global contribution of coralline algae to carbon burial, a critical aspect of carbon sequestration in marine ecosystems. The authors estimate the extent to which coralline algae contribute to carbon storage in marine sediments worldwide.
Impacts on Atlantic rhodolith beds: Implications for estimates of blue carbon ecosystem services
This article discusses the EU-funded RHODOCAR project, which explores rhodolith beds as vital marine habitats and significant carbon stores. The project investigates how these ecosystems respond to stressors, their role in carbon sequestration, and their potential inclusion in climate mitigation policies.
Comparison of marine macrophytes for their contributions to blue carbon sequestration
This study examines how the structural integrity of marine ecosystems impacts long-term carbon sequestration, using thermogravimetric analysis on 14 taxa of macroalgae and coastal plants. The study found that calcareous algae, with structures reinforced by calcium carbonate, resist degradation at higher temperatures than other algae, making them more effective for long-term carbon storage.
Coralline Algae: Globally Distributed Ecosystem Engineers
This editorial highlights coralline algae as vital "ecosystem engineers," enhancing marine biodiversity and habitat stability worldwide. Their calcareous skeletons support other organisms, aid reef-building, and protect coasts. The authors emphasise the global importance of coralline algae and call for further research and conservation.
The Critical Importance of Rhodoliths in Life Cycle Completion of Both Macro and Microalgae
The article emphasises the critical role of rhodoliths in marine ecosystems, highlighting their function as essential habitats. It explores how rhodoliths act as holobionts, supporting diverse communities of organisms and facilitating the life cycles of algae. These findings underscore their importance in maintaining and enhancing marine biodiversity.
Levelling-up rhodolith-bed science to address global scale
conservation challenges
The article highlights the urgent need for research on rhodolith beds - critical ecosystems supporting biodiversity but threatened by human and environmental impacts. It calls for global, interdisciplinary efforts to improve understanding and conservation strategies to protect these valuable marine habitats.
An Overview of Rhodoliths: Ecological Importance and Conservation Emergency
The article highlights the ecological importance of rhodoliths as habitat-forming structures that support biodiversity, stabilize sediments, and store carbon. Facing threats from human activities and climate change, it emphasizes the urgent need for conservation measures to protect these vital marine ecosystems.
Positive species interactions structure rhodolith bed communities at a global scale
Rhodolith beds stabilise substrates, buffer physical stress and increase resource availability, supporting diverse marine species. They also serve as climate refugia and amplify community interactions by supporting secondary facilitators. These cascading benefits underscore their critical role in coastal ecosystem stability and the need for conservation efforts.
