Groundwater-derived nutrient fluxes and offshore mixing rates along the New Jersey coast 21-23

Radium isotopes are natural tracers useful for studying the magnitude of groundwater discharge and the transport and fate of nutrients in the coastal ocean. We collected radium and nutrient samples from groundwater and surface waters along the southern New Jersey coast to calculate the flux of groundwater-derived nutrients and coastal mixing rates. These data serve as baselines for assessing future changes in the magnitude and quality of groundwater discharge driven by human activity and climate change.镭同位素（Radium isotopes）是一类天然示踪剂，可用于研究海岸带海域地下水排泄量，以及营养盐的输运过程与归宿。本研究沿新泽西州南部沿岸采集了地下水与地表水的镭同位素及营养盐样品，用于计算地下水携带营养盐的入海通量，以及近岸水体混合速率。本数据集可作为基准，用于评估人类活动与气候变化驱动下，地下水排泄的规模与水质未来变化情况。
