It provides a means to monitor the areas rich in plankton by remote sensing, and therefore to detect from space the potential reservoirs for Vibrio around the coasts.

Lohafex provides new insights on plankton ecology

The Indo-German team of scientists from the National Institute of Oceanography and the Alfred Wegener Institute has returned from its expedition on research vessel Polarstern. The cooperative project Lohafex has yielded new insights on how ocean ecosystems function. But it has dampened hopes on th...

Decline of carbon-dioxide-gobbling plankton coincided with ancient global cooling

ITHACA, N.Y. The evolutionary history of diatoms -- abundant oceanic plankton that remove billions of tons of carbon dioxide from the air each year -- needs to be rewritten, according to a new Cornell study. The findings suggest that after a sudden rise in species numbers, diatoms abruptly declin...

Puzzling plankton yield secrets to role in evolution/global photosynthesis

The analysis of DNA sequences from tiny green algae have provided new insights into the mystery of how new species of plankton evolve—and further highlights their critical role in managing the global cycling of carbon. These findings, by a group led by the DOE Joint Genome Institute (DOE JGI); the...
