Short summary

A "young" warm-core eddy and an "older" warm-core eddy further south were surveyed in the Southern Ocean to study differences in their heat, salt and nutrient characteristics. Results show that warm eddies that migrate from the polar front further south lose heat but gain dissolved silicate and exhibit much higher levels of chlorophyll-a. This demonstrates important heat and nutrient exchange processes associated with eddy transport in the ocean.
