Abstract
Submarine groundwater discharge (SGD) is an important link between the land and ocean. In this study, eddy diffusivity coefficients (K-h) and SGD rates were examined off the Jetty Beach in Coffs Harbour (Australia) in September 2017 and 2018. In order to estimate K-h, the apparent age and SGD, two short-lived radium isotopes Ra-224 and Ra-223 were measured along a shore-perpendicular transect and beach groundwater. Estimated SGD rates were 3.3 and 5.4cmday(-1) in 2017 and 12.7 and 9.3cmday(-1) in 2018, based on average Ra-224 and Ra-223 groundwater endmember activities. The SGD flow was higher in 2018 due to the combination of a spring tide and rainfall events that took place prior to sampling.
