KAUST researchers, partnering with the Queensland Government, discovered 34 previously unknown seagrass meadows in the Red Sea by tracking the foraging behavior of green turtles. They tagged and tracked 53 turtles, revealing that the turtles were approximately 20 times more reliable at identifying seagrass meadows compared to the Allen Coral Atlas. This method also proved to be significantly more cost-effective than traditional methods like airplanes with hyperspectral sensors. Why it matters: This study highlights a novel, cost-effective approach to mapping blue carbon ecosystems, crucial for carbon capture and marine habitat preservation, and provides valuable data for sustainability policies in the Red Sea region.

KAUST held a Research Workshop on Blue Carbon on March 20 and 21. The workshop focused on the role of blue carbon ecosystems, such as mangroves and seagrass meadows, in mitigating climate change. Experts discussed the importance of these ecosystems. Why it matters: This highlights growing research and awareness in Saudi Arabia around leveraging natural resources for climate solutions.

KAUST's coastal wetlands contain 90 hectares of protected mangroves that support over 240 bird species and various marine life. These mangroves, predominantly Avicennia marina, sequester CO2 at a rate 30 times higher than other forests, burying it in sediment. This "blue carbon" storage occurs because the lack of oxygen in mangrove soils prevents the degradation of organic matter. Why it matters: This highlights the critical role of Red Sea mangroves in carbon sequestration and biodiversity, emphasizing their importance for regional climate change mitigation.

KAUST researchers and German collaborators explored the Red Sea's depths using the RV Meteor, employing ROVs and seismic equipment to map geological and biological features. They examined underwater hot springs, microbial mats, and deep-sea brine pools, discovering hydrothermal vent fields with unique ecosystems. The research, involving multidisciplinary teams, provides insights into the Red Sea's geology, ecosystems, and biodiversity. Why it matters: Studying the Red Sea's unique environment can offer valuable knowledge about young ocean development and novel marine ecosystems, relevant for understanding similar geological formations and biodiversity hotspots in the region.

KAUST researchers from the Red Sea Research Center are studying mesophotic reefs (40-150m deep) as potential climate refuges for corals threatened by marine heatwaves. These deeper reefs experience less heat and light stress compared to shallow-water corals. Advanced tools like submarines and robots are now enabling the study of these previously neglected ecosystems. Why it matters: Understanding the resilience of Red Sea corals could provide crucial insights for global coral reef conservation strategies amid climate change.
