El Niño phenomena is causing less rainfall in different areas including the Jellyfish lake in Palau. Because of the lack of rain, the lagoon becomes saltier driving both plankton and the jellyfish away.
In the dark polar night, when the moon appears over the horizon, things happen. That is, the huge mass of tiny marine life, or zooplankton, take on a migration in order not to be viewed by their light-seeing predators.
Darkness blankets the icy north in the winter, but tiny Arctic marine creatures are guided by the light of the moon. Researchers say the creatures' regular vertical migrations could help store more carbon deep in the ocean.
A new study suggests that a nutrient-rich, balanced diet can boost coral resilience under thermal stress, which can be caused by climate change.
Great diversity, reproductive action, and seabird feeding was taking place in the pitch-dark, three consecutive winters that researchers recently spent in the Arctic Circle. In their report, they talk about the wisdom of allowing human industry into a very busy, and rare, wildlife region.
