A new study using NASA and National Oceanic and Atmospheric Administration (NOAA) data finds consistent evidence that Earth's ozone layer is on the mend. Using balloons, ground-based equipment and NASA/NOAA satellites, a team of researchers analyzed 25 years of independent ozone observations at different altitudes in Earth's stratosphere. The data shows that the ozone layer in the polar regions may have stopped thinning in 1997 after a steady decline of 18 years. The presence of human-produced ozone-destroying gasses also peaked around the same time that the ozone layer was at its thinnest. The results indicate that phasing out the use of ozone-destroying gasses may have stopped the loss of ozone in the stratosphere. In addition, the ozone layer may be improving faster than scientists had expected. The results of the study were recently published in the Journal of Geophysical Research - Atmospheres.

Antarctic Icebergs: Unlikely Oases for Ocean Life
(NSF) - Scientists have found that trapped terrestrial material released from icebergs as they melt out at sea has a major impact on the ecology of the ocean around them. The floating chunks of ice support thriving communities of ocean life, and may play an important role in climate regulation on Earth.

(NASA) - The MBARI Environmental Sample Processorthe ESPprovides on-site (in situ) collection and analysis of water samples from the subsurface ocean. The instrument is an electromechanical/fluidic system designed to collect discrete water samples, concentrate microorganisms (particulates), and automate application of molecular probes which identify microorganisms and their gene products. The ESP also archives samples so that further analyses may be done after the instrument is recovered.
