The ammonia oxidizing archaea, or Thaumarchaeota, are amongst the most abundant marine microorganisms. Yet, we are still discovering which factors allow them to thrive in the ocean. A research team from the Max Planck Institute for Marine Microbiology in Bremen and the University of Vienna was now able to show that marine Thaumarchaeota have a broader metabolism than previously thought. The results are published in the journal Nature Microbiology.
By combining ocean models, animal metabolism and fossil records, researchers show that the Permian mass extinction in the oceans was caused by global warming that left animals unable to breathe. As temperatures rose and the metabolism of marine animals sped up, the warmer waters could not hold enough oxygen for their survival.
Surface melting across Greenland's mile-thick ice sheet began increasing in the mid-19th century and then ramped up dramatically during the 20th and early 21st centuries, showing no signs of abating, according to new research published Dec. 5, 2018, in the journal Nature. The study provides new evidence of the impacts of climate change on Arctic melting and global sea level rise.
New research shows that mussels readily take in microplastic pollution fibers from the ocean but quickly flush most of them out again, according to a study by researchers from Bigelow Laboratory for Ocean Sciences.
A new study by MBARI scientists shows that pulses of sinking debris carry large amounts of carbon to the deep seafloor, but are poorly represented in global climate models.
Understanding how the ocean works is like putting together a million-piece puzzle. There are many questions; finding answers takes time, resources, and opportunity. But even when scientists believe they know how the pieces fit together, new knowledge can change the shape of the puzzle. A paper recently published by Dr. Jeffrey Krause of the Dauphin Island Sea Lab and the University of South Alabama adds another piece to the puzzle in understanding the impact of diatoms on the Arctic Spring Bloom.
The pattern of uneven sea level rise over the last quarter century has been driven in part by human-caused climate change, not just natural variability, according to a new study.
A new study involving Kansas State University researchers reveals that water storage declines in global landlocked basins has aggravated local water stress and caused potential sea level rise.
A new Chinese project (2018--2022) will explore the sources and transport of biologically available Fe in the high-nutrient and low-chlorophyll (HNLC) regions. The results can give scientific advice to stakeholders on the feasibility of conducting ocean Fe fertilization.
Stanford researchers took a virtual reality experience into a variety of educational settings, including high school classrooms, to test the impact on awareness and understanding of ocean acidification.
