A Global Scale Assessment of Hydrodynamics Effects on Biogenic Carbonate Distribution

Many attempts have been made to understand the relationship between biogenic carbonate sediments and abiotic factors on a global scale, both in present-day settings and in the geological record. Although the majority of these studies focus on geochemical and large-scale oceanographic controls, the effects of hydrodynamics are often overlooked. While local-scale research confirms that hydrodynamic energy plays a crucial role in shaping coastal sedimentary environments, quantitative and standardized studies at a global scale remain scarce. The aim of this work is to address this gap in knowledge by expanding a global-scale database of biogenic carbonate sediments, utilizing AI-assisted literature research. By coupling this record with satellite-derived abiotic datasets, a standardized quantitative framework was established to correlate sediment components with environmental parameters globally. To isolate hydrodynamic variables, specifically current, wind, and tide parameters, findings of previous analyses were re-evaluated over the expanded dataset. While initial results indicate that fundamental patterns remain consistent despite the increased data volume, the implementation of this standardized approach facilitates the isolation of hydrodynamic drivers at a global scale, allowing for the observation of their distinct effects on biogenic carbonates distribution. This methodology clarifies the global dynamics of environmental factors over biogenic carbonate production, providing a robust baseline for assessing sediment response to hydrodynamic forcing in the context of climate change.
