Monitoring Marine Ecosystems: Ocean Acidification and New Efforts in Real Time Assessment

Monitoring Marine Ecosystems: Ocean Acidification and New Efforts in Real Time Assessment | green infographics | Scoop.it
Scientists have developed a satellite technique to capture a near real-time view of ocean acidification.

Their findings, published in the journal Environmental Science and Technology, showing how data from satellites that measure salinity and other ocean conditions could be combined to produce a new way of monitoring acidification.

Oceans are taking in about 90 percent of the excess heat created by human greenhouse gas emissions, but they’re also absorbing some of the carbon dioxide (CO2) itself. 

A set of chemical processes dissolves that CO2 and turns it into carbonic acid and sets off a complex changes to the chemistry of seawater, which dissolves shells and coral and creates a cascade effect that could disrupt entire marine ecosystems.

A recent study estimated $1 trillion annually in losses caused by ocean acidification by 2100, if left unmitigated. Some research has looked at “designer” corals and other creatures that could survive more acidic seas but more work needs to be done to figure out just what will thrive (or at least survive) the changing acidity...

Scorecard for the Sea: The Ocean Health Index

Scorecard for the Sea: The Ocean Health Index | green infographics | Scoop.it
To feed, employ, and sustain the world, our oceans must first be in good health. It is becoming increasingly clear that humans have a substantial impact on these marine ecosystems, and that these impacts are not just threatening the high-seas, but also the humans that depend on them for their livelihoods and well-being.

The health of our oceans is, therefore, primarily a human concern. But how do we measure the health of something as vast and bewildering as an entire ocean?

For many years, scientists have struggled to find a way to make the concept of ocean health meaningful and measureable. There have been a few breakthroughs but no real solution to allow us to concretely measure if things are getting better or worse and by how much? That is, until now.

Published in last week’s issue of the journal Nature The Ocean Health Index is a groundbreaking tool that allows us to take a look at how we as humans benefit from the big blue. The Index examines social, economic, and ecological factors, scaling both globally and locally to give us an accurate assessment. It finally gives us the baseline we need to measure progress...
