Blue Carbon and Green Kelp: Kelp forests could reduce carbon emissions

Blue carbon is the carbon that is stored within marine ecosystems. It is being used more frequently within global carbon budgets, which are calculated to help us reduce climate change. Historically, only tidal marshes, mangrove forests, and seagrass beds have been used in calculating stored carbon for carbon budgets. A team of researchers from Norway wanted to see if kelp forests could significantly contribute to carbon storage. They studied the kelp forests along Australia’s southern coast and found their storage potential to be similar to that of the other historically used ecosystems. Conserving and restoring kelp forests could therefore increase carbon storage and help reduce climate change.

In otter news: Disappearing otters and climate change spell double trouble for reefs

As many people know, sea otters are great at being adorable. But do sea otters also play an important role in combating the impacts of climate change? In this study, scientists looked at how the loss of sea otters might be making reefs more susceptible to climate change.

How do kelp forests change water conditions and microbial communities?

In honor of World Algae Day which is celebrated on October 12th, we cover a recent study on charismatic kelp forest in the Pacific Northwest. A study led by Cathy Pfister at the University of Chicago shows that kelp forests can change water conditions by locally decreasing pH which can benefit organisms with shells. Furthermore, kelp forests increase the diversity of microbes, which may have previously overlooked consequences for nutrient cycling.
