Fig. 2: Denitrification changes in the Gulf of California.
From: North Atlantic temperature control on deoxygenation in the northern tropical Pacific
A Long-term δ15N (‰) record at core site MD02-2515/17 showing changes in deoxygenation-related denitrification over the last 55,000 years, with position and δ15N range of the 10 annually resolved record (red and blue triangles). B Annually resolved (blue circles) and 3-year averaged (solid line) 200 year-long δ15N (‰) record for section #10 showing interannual to multidecadal variability in deoxygenation around 14,500 BP. The error bars are within the circles and triangles.
