Deep ocean microbes may already be prepared to tackle climate change

What Happened

In recent weeks, several significant scientific discoveries have shed new light on the natural world and our impact on it. Researchers have found that deep ocean microbes may already be adapting to the effects of climate change, and a new test can detect PFAS in water at incredibly low levels. Meanwhile, a study on Baltic herring has revealed new insights into the fish's genetic diversity, and scientists have discovered that microbes can limit the depth at which marine snow sinks in the ocean.

Deep Ocean Microbes and Climate Change

A study published in the Proceedings of the National Academy of Sciences has found that the microbe Nitrosopumilus maritimus is surprisingly adaptable to warmer, nutrient-poor waters. This discovery suggests that these microbes may play an important role in reshaping biodiversity in the planet's oceans as the climate changes.

Detecting PFAS in Water

Sandia scientists Ryan Davis and Nathan Bays have developed a faster, cheaper way to test for PFAS in water. The new method can detect PFAS at levels as low as parts-per-trillion, making it a significant breakthrough in the effort to address the problem of these persistent pollutants.

Baltic Herring and Genetic Diversity

A new study by researchers from Uppsala University, Stockholm University, and the Swedish University of Agricultural Sciences has found that herring from different parts of the Baltic Sea belong to distinct populations genetically adapted to local differences in salinity and temperature. This discovery has implications for the management of herring fisheries in the region.

Microbes and Marine Snow

Researchers at MIT have found that microbes can hitch a ride on marine snow particles and eat away at calcium carbonate, limiting the depth at which the particles can sink. This discovery could explain how carbon is cycled through the ocean and has implications for our understanding of the ocean's role in the global carbon cycle.
