Reducing Uncertainty in Understanding Ocean Oxygen and Nitrogen Cycles
Description: This study utilized a combination of recently available globally spatially explicit datasets - in particular correcting World Ocean Atlas (WOA) for its bias at the O2 extremes - for a revised look at the global nitrogen cycle. Researchers evaluated the distribution of the Oxygen Minimum Zones (OMZ)s by (1) mapping high-quality oxygen measurements, and (2) by applying an empirical correction to the gridded WOA based on in situ observations. They then combined the new oxygen data sets with estimates of global export and simple models of remineralization to estimate global denitrification and production.
