             Ocean Deoxygenation Due to Climate Change Between 2030 and 2040  (credit: Matt Long, NCAR)

Publishing their research in Global Biogeochemical Cycles , the National Center for Atmospheric Research (NCAR) based in Colorado announced that widespread loss of ocean oxygen will become noticeable in 2030s. NCAR reports that a drop in the amount of oxygen dissolved in the oceans due to climate change is discernible in some parts of the world already.

Matt Long, the lead author of the NCAR study stated:

“Loss of oxygen in the ocean is one of the serious side effects of a warming atmosphere, and a major threat to marine life. Oxygen concentrations in the ocean naturally vary depending on variations in winds and temperature and this new study tells us when we can expect the impact from climate change to overwhelm the natural variability.”

Riled Up noted this existential relationship between marine phytoplankton, ocean chemistry, and the impact of acidification on biology previously: High School chemisty and Biology. That post was intended to show elements of climate change science that were readily found in most high school textbooks and could also explained in a phytoplankton video.

The NCAR researchers created the oceanic deoxygenation maps to help plan more ocean oxygen monitoring. Maps will be needed to decide where to place oxygen monitoring sensors to obtain the best picture of the climate change impacts. Currently, such phyto-chemistry measurements are sparse. Matt Long continued: 

“We need comprehensive and sustained observations of what’s going on in the ocean to compare with what we’re learning from our models and to understand the full impact of a changing climate.”

Life emerged from algae in the seas, what is called pond-scum now, and the ocean's algae produces upwards of 70% of the Earth's oxygen that is breathed. The NCAR finding couldn't be more important now for the implementation of CO2 reduction plans on a global 'fast track' basis.
