UCI oceanographers predict increase in phytoplankton by 2100

Machine learning Earth system model projects higher numbers in low-latitude regions University of California – Irvine Irvine, Calif. – A neural network-driven Earth system model has led University of California, Irvine oceanographers to a surprising conclusion: phytoplankton populations will grow in low-latitude waters by the end of the 21st century. The unexpected simulation outcome runs…

NASA, French Space Laser Measures Massive Migration of Ocean Animals

From NASA Global Climate Change Researchers used the space-based CALIPSO lidar to measure the planet’s largest animal migration, which takes place when small sea creatures swim up from the depths at night to feed on phytoplankton, then back down again just before sunrise.

Animals could help humans monitor oceans

oceans University of Exeter Sharks, penguins, turtles and other seagoing species could help humans monitor the oceans by transmitting oceanographic information from electronic tags. Thousands of marine animals are tagged for a variety of research and conservation purposes, but at present the information gathered isn’t widely used to track climate change and other shifts in…

Water Behaving Badly

Guest Post by Willis Eschenbach Those who know me are aware that I’m a tropical boy, a hopeless addict of warm blue seas and coconut-laden islands with white sand beaches. Here’s where I used to live and work, Liapari Island in the Solomon Islands. That is how I like my water to behave, soft, warm,…

Is a great iron fertilization experiment already underway?
