The arguments about uncertain global effects and limited efficacy have been supported by others for years.

One more thing: if harmful blooms or hypoxic fish kills happen anywhere that is influenced by OIF, legal fingers will point, deservedly or not.

Who will underwrite liability insurance?

Mary Somerville was born on 26 December 1780. Among her many accomplishments, she described foundational principles of ocean optics – including the influence of phytoplankton on ocean color. The 20th century pioneers of ocean-color remote sensing were unaware. She was far ahead of her time. 🌊🧪

Frenger et al. (doi/10.1111/gcb.17124) remind us that export flux of organic C by the biological pump cannot be equated to the flux of atmospheric CO2 to the ocean. We must account for upward transport of DIC, including DIC:N:P in vertically transported nutrients. Read quote from classic 1979 paper.
