The old way to search for
microbial life in the ocean, he explains, was to isolate individual species by growing them in laboratory cultures.
Through photosynthesis, tiny organisms that
live in the ocean surface waters pull carbon - dioxide out of the atmosphere, which usually means cooler temperatures.
As scientists continue finding evidence for
life in the ocean more than 3 billion years ago, those ancient fossils pose a paradox.
The amounts of CO2 involved indeed are huge to make that small difference in pH. What that implies for
life in the oceans remains to be seen.
It manages to sum up in just a couple minutes the chemistry that is changing the balance of
life in our oceans right now.
His specialty is
microbial life in oceans, and his particular interest is the way that viruses drive the evolution and regulate the activities of bacteria.
For
most life in the oceans, warming means faster growth, reduced energy requirements to stay warm, lower winter mortalities, and wider ranges of distribution.
A new study from the Ohio State University have tripled the known types of viruses
living in oceans around the world, providing new insights on the role of viruses in marine environment.
«Once we have those answers, we can tackle the bigger question
about life in the ocean beneath Europa's ice shell.»
In order to be able to make more precise and globally applicable prognoses concerning the effects of climate change
on life in our oceans, marine biologists have long sought to find universal principles that would allow them to describe the living conditions in the oceans and at their borders.
«Although tiny, these organisms are a vital part of the Earth's life support system, providing half of the oxygen generated each year on Earth by photosynthesis and lying at the base of marine food chains on which all other
life in the ocean depends.»
Adds Aronson: «We absolutely must control emissions of the principal greenhouse gas, carbon dioxide, if we are going to preserve
life in the oceans in some approximation of the way it should be.»
Now, after running DNA tests on a gift of dried whale meat given to a scientist visiting islands in the Pacific, researchers have confirmed that there's a whole new species of beaked
whale living in our oceans — and there may be others out there.

«Since no
organisms living in the ocean today would have time to adapt to these warmer conditions, many will either go extinct or migrate away from the western Pacific, leaving this area with much lower biodiversity.»
Organisms, including the single - celled bacteria
living in the ocean at that early date, need a steady supply of phosphorus, but «it's very hard to account for this phosphorus unless it is eroding from the continents,» says Aaron Satkoski, a scientist in the geoscience department at the University of Wisconsin - Madison.
More distressing news about the decline of
life in the oceans came in with another report, which shows that ocean acidification (fueled by ACD) is expected to cause skeletal deformities in half of global juvenile corals, making them increasingly susceptible to dying off.
Viruses, which can
live in the ocean for days or weeks, can be transported great distances via ocean currents.
Our brain structures are based upon how our species evolved from primitive
worms living in the oceans, with limbic systems becoming mutated simply because such things survived to further evolve in random ways mostly affected by our environment and basically random chance.
She would
live in the ocean if it was physically possible, but until then, she lives in Toronto, Canada.
Discover
who lives in the ocean and count these adorably illustrated sea creatures by popping the plastic dots on one page, then turn the page and pop the sensory dots the opposite way for never ending toddler fun!
«At the heart of the investigation is the question about
whether life in the ocean, as it moves about the environment, does any important «mixing,»» says William Dewar, an oceanographer at Florida State University in Tallahassee.
Metagenomics has already been used to sequence people's gut flora, and the geneticist Craig Venter famously tried to sequence the uncounted
microbes living in the ocean.
She was trained as a neuroscientist, but her specialty made her a good fit for the voyage: For her Ph.D. she had studied the neurological signal that triggers the flash of bioluminescence in dinoflagellates (mostly single - celled
plankton living in oceans or lakes).
The presence of plate tectonic activity could have important implications for the possibility of
life in the ocean thought to exist beneath the moon's surface.
Researchers think the moon's icy crust may be just a few kilometres thick — perhaps thin enough to crack open under tidal stresses and
allow life in the oceans below to flourish by absorbing the Sun's energy.
And that this enabled the expansion of
complex life in oceans, and paved the way for our own evolution,» says Dr Ernest Chi Fru of Stockholm University, who has led the research group.
