Melting ice, shifting microbes
Polar bears have been the poster child for sea ice melting in the Arctic. But what does sea ice loss melt mean for the Arctic’s most numerous members – its microbes? Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why do we find microbes […]
A blanket of oil: the role of bacteria in cleaning up after Deepwater Horizon
Nearly one million barrels of oil landed on the seafloor after the Deepwater Horizon spill – a feast if bacteria are able to consume it. Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why do we find microbes where they are in the seafloor, […]
Popping bubbles: Measuring nitrogen fixation in the ocean
Scientists have been measuring nitrogen fixation in the ocean wrong – but a new method offers a simple fix. Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why do we find microbes where they are in the seafloor, and what are they doing there? […]
The answer to starvation? Diversity
Photosynthetic microorganisms can’t go it alone, so they succeed by playing host to a diverse array of microbial partners Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why do we find microbes where they are in the seafloor, and what are they doing there? […]
The ocean’s tiny, mysterious majority
The earth has more viruses than the universe has stars – but we know far less about our tiny majority at home than we do about the glowing balls of gas in our night sky. Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why […]
Toxic living: finding the right home for sulfur-oxidizing bacteria
Hydrothermal vents are hot, dark, and toxic environments. But to sulfur oxidizing bacteria, they’re home. Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why do we find microbes where they are in the seafloor, and what are they doing there? I spend my non-science […]
Stressed-out microbes in an acidifying ocean
The ocean is acidifying in response to carbon dioxide emissions, but we are just beginning to learn how this effects the ocean’s most abundant lifeforms – microbes. Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why do we find microbes where they are in […]
Suffocating crabs and a one-way street for carbon
Seafloor life is in danger of running out of oxygen as the ocean warms, but this may actually help to mitigate climate change. Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why do we find microbes where they are in the seafloor, and what […]
Methane on the dinner menu
Bacteria in coastal waters can eat methane, a greenhouse gas – but just how much and how fast can they eat? Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why do we find microbes where they are in the seafloor, and what are they […]
