Great Slave Lake’s huge cold water mass shielded it from impacts of the rapidly warming climate—until now.
The Arctic’s thinning sea ice allows more light to penetrate deeper into the ocean, holding zooplankton far beneath the surface.
Certain microbes that engage in both photosynthesis and predation are more likely to do the latter as the planet warms, resulting in a net release of carbon dioxide.
Nutrients from the seabirds’ guano fuels the growth of carbon-storing phytoplankton, but penguin populations have plunged in the past 4 decades.
Researchers tracked plankton through a changing climate over 8 million years. Now, that knowledge is helping scientists understand the coming effects of warming oceans.
Diatoms contribute to global oxygen production, marine food webs, and carbon sequestration, but scientists predict that diatom populations will decline due to ocean acidification associated with climate change.
Melt ponds in sea ice have thriving algal communities with startlingly high levels of photosynthetic activity.
A new study describes eukaryotic organisms found organized in a cortex-medulla pattern in southern China’s Kuanchuanpu Formation.
Mammal teeth store a record of the plants they ate, providing clues about the ecosystems in which they lived.
A comparison of primary productivity measurements across the North Pacific Ocean demonstrates the potential for using autonomous instruments to discern effects of climate change on the marine food web.
