Predicted Episode of Submarine Groundwater Discharge Onto the South Carolina, USA, Continental Shelf and Its Effect on Dissolved Oxygen

Submarine groundwater discharge can directly influence coastal bottom waters' dissolved oxygen content. Low DO concentrations on the South Carolina continental shelf have been predicted here. The prediction model linked episodes of SGD to upwellingu2010favorable winds. These waters were a factor of 2u20136 higher in 226Ra and 228Ra in comparison to average bottom water levels, and were significantly depleted in DO, according to the analysis.

1,100‐Year Reconstruction of Baseflow for the Santee River, South Carolina, USA Reveals Connection to the North Atlantic Subtropical High

Extreme floods within the Santee River basin in 2013 caused $1. 5 billion in damage. This year, we have compiled reconstructions of storm u2010, base u2010, and total streamflow for the Santee River using a multi-u2010species tree network calibrated to flow data during the period 1923u2013-2018. The higher variance of instrumental baseflow showed more variability than total streamflow or stormflow in Treeu2010ring results, according to treeu2010ring results. Baseflow in the Santee River is controlled by a North Atlantic subtropical high.
