According to a new scientific study, it would appear that even low-scale climate fluctuations can affect the habitability of marine ecosystems to a great extent. The researchers who led the work say that the size and harshness of oceanic dead zones is directly correlated to climate. In the investigation, researchers ... |

Experts in the United States anticipated that this year's Gulf of Mexico dead zone will be the largest ever recorded. The phenomenon's usual spread will be augmented by the Mississippi River floods that scarred the central United States earlier this year. University of Michigan aquatic ecologist Donald Scav... |

For about four billion years after the Earth first solidified from a ball of molten lava, the world's oceans were oxygen-poor mixtures of various chemicals, boasting levels of acidity that were well beyond those life can thrive in. A new study now shows the challenges early life had to face. Until some 600 milli... |

The main question in astronomy today is related to identifying the places in the Universe where life has the most chances of appearing, developing and enduring. While many experts look for such places based on one theory or the other, some are trying to determine where life could never appear. In other words, they ar... |

According to officials at the US National Oceanic and Atmospheric Administration, it would appear that no dead zones have developed around the area of the Gulf of Mexico where the Deepwater Horizon drilling rig blew up a few months ago. These conclusions did not come as a surprise for the science team, which was expe... |

A team of experts was recently awarded a research grant to investigate the level of hypoxia in Lake Michigan. Land use and climate change are taking their toll on the important lake, and experts from a US collaboration of scientists are scheduled to begin investigating the extent of this influence. The group will loo... |

Investigations conducted in the Gulf of Mexico have revealed that the dead zone which developed there this year is the fifth largest on record. The formation covers an area about the same size as the state of New Jersey.Scientists with the US National Oceanic and Atmospheric Administration (NOAA) conducted a recent s... |

Oceanic dead zones are areas in the open sea, or around shorelines, where accumulations of various types of pollutants have caused a massive drop in the number of species living at the location. For example, where rivers bring fertilizers into the water, microbes multiply to such extent that they remove all of the ox... |

Even without the current oil spill affecting the Gulf of Mexico, the area is very polluted on its own. Every year, waves of agricultural and human runoffs are spilled into its waters from the Mississippi Basin, creating so-called “dead zones.” In these areas, animals either flee or die, and the regions st... |

Dead zones is a term used to describe areas of the oceans or seas that have been so heavily contaminated with pollutants, that it's virtually impossible for fish and other marine animals to live there. Only some types of algae manage to survive in the toxic conditions, and, by thriving, they consume the short su... |

Scientists keeping an eye on the dead zone in the Gulf of Mexico, an area where oxygen levels have dropped to such lows that they no longer sustain animal and plant life, have reported that, this year, the formation is smaller than anticipated, but that the overall extent of the damage has increased considerably. The... |
