Mixing Up Microalgae
A recent study shows that within the mixed layer—the region of the upper ocean where temperature and salinity are homogeneous—biological properties may not actually be well mixed. These results have implications for our understanding of phytoplankton biomass distribution.

Predicted Change to the Southern Ocean Silicate Front
The Southern Ocean Silicate Front (SF) is an important boundary separating waters that are silicate-rich and waters that are silicate-poor. The position of the SF determines where microorganisms like diatoms (that need silicate to form their shells) can grow. A new study predicts a poleward shift in the Southern Ocean Silicate Front by the end […]
The Declining Japanese Eel Population: Is Ocean Circulation to Blame?
Recent declines in Japanese eel populations have been attributed to overfishing, but that may not be the only factor at play. Chang et al. investigate whether recent changes in ocean circulation might help explain this alarming trend. Julia DohnerJulia is a PhD student at Scripps Institution of Oceanography in La Jolla, California. Her focus is […]
