The Naval Research Laboratory, which created radar and the GPS navigational system among other well-known technologies, is applying its talents to designing and testing unmanned undersea vehicles that also fly. Flimmer is the latest in a veritable zoo of odd creatures that the U.S. Naval Research Laboratory (NRL) has created over the years to map […]

Originally Published by EurekAlert! – Earth ScienceA new study has found a link between abrupt ocean warming at the end of the last ice age and the sudden onset of low-oxygen, or hypoxic conditions that led to vast marine dead zones. Results of the study, which was funded by the National Science Foundation, are being […]

El Niño rains for dry California but scientists fear for coral reefs

Originally Published by Environment | The GuardianData suggests giant climatic event could be the strongest on record, meaning rains for drought-stricken California and a worsening of the coral die-off The giant El Niño climatic event is set to bring rain to drought-stricken California by January, but is likely to exacerbate a widespread die-off of corals […]

Every species counts: Value of biodiversity is particularly high in poor environmental conditions

Originally Published by Earth & Climate News — ScienceDailyThe relationship between biodiversity and ecosystem functioning greatly depends on the prevalent environmental conditions. An interdisciplinary team consisting of microbiologists and ecological modellers has now tested this hypothesis which is considered crucial for biodiversity research. Through laboratory experiments on microbial communities, the researchers were able to demonstrate […]

Free Data Proves Its Worth for Observing Earth

Originally Published by USGSSince late 2008, when Landsat earth observation images were made available to all users free of charge, nearly 30 million Landsat scenes have been downloaded through the U.S. Geological Survey portal – and the rate of downloads is still increasing. Topic: Education
