ABSTRACT
The short-lived Ra isotope was measured in coastal water samples from Laizhou Bay, China using a radium delayed coincidence counting system. Based on the horizontal distribution of Ra and a mixing model, the horizontal eddy diffusion coefficient was estimated to be 253.1 × 10 and 56.5 × 10 m/d for the surface and middle layers, respectively. The submarine groundwater discharge (SGD) into the bay was estimated on the basis of the Ra mass balance model. The estimate of the SGD into the bay is 4.2 × 10 m/d, approximately six times the annual average flux of the Yellow River.

    Despite the great number and variety of glaciers in southern South America, in situ glacier mass balance records are extremely scarce and glacier-climate relationships are still poorly understood in this region. Here we use the longest (> 35 years) and most complete in situ mass balance record,...
