This project aims to examine the role of mangroves in the sequestration and burial of nutrients. Coastal areas increasingly receive enriched nutrient loads, driving anthropogenic eutrophication. Mangrove wetlands naturally filter and bury large quantities of nutrients through soil accretion. This project aims to quantify nutrient groundwater export as related to mangrove soil nutrient retention and determine if these wetlands have the potential to provide negative feedback to coastal eutrophication. The project plans to use state-of-the-art radionuclide tracer technology to quantify the relationship between groundwater discharge and historical soil nutrient retention.

该项目旨在研究红树林在固存和掩埋营养物质方面的作用。沿海地区越来越多地接受富营养化负荷，推动人为富营养化。红树林湿地通过土壤生长自然地过滤和掩埋了大量的营养物质。该项目旨在量化与红树林土壤养分保持相关的营养地下水输出，并确定这些湿地是否有可能对沿海富营养化提供负反馈。该项目计划使用最先进的放射性核素示踪技术，以量化地下水排放与历史土壤养分保持之间的关系。
