AI Thread Summary
Adult North Pacific blue whales consume approximately 16 metric tons of krill daily during foraging season, while bowhead whales eat around six metric tons of zooplankton each day. A study led by marine ecologist Matthew Savoca from Stanford University analyzed data from 321 tagged whales across various oceans, revealing that previous food intake estimates were based on limited measurements. The research indicates that restoring whale populations could enhance phytoplankton levels, potentially allowing for the absorption and storage of over 200 million metric tons of carbon in ocean systems. Additionally, whale feces play a crucial role in supporting life forms at the bottom of the marine food chain, further emphasizing their ecological importance.

Marine ecologist Matthew Savoca, from Stanford University, is the lead author of a study that looks at how much food these giant mammals actually consume. Previous estimates of their food intake was largely based on just a few measurements, so the team looked at data from 321 tagged whales sized between 30 and 100 feet that lived in the Atlantic, Pacific and Southern Oceans.

The study suggests that if whale populations were restored, and levels of phytoplankton increased accordingly, over 200 million metric tons of carbon could be absorbed and stored in ocean systems. These benefits could also increase year on year, the team says.
And whales produce a lot of poop, which feeds life forms at the bottom of the food chain.

The study provides critical new insights into the African Humid Period, a time between 14,500 and 5,000 years ago when the Sahara desert was a green savanna, rich in water bodies that facilitated human habitation and the spread of pastoralism. Later aridification turned this region into the world's largest desert. Due to the extreme aridity of the region today, DNA preservation is poor, making this pioneering ancient DNA study all the more significant. Genomic analyses reveal that the...
