  • Taking a deep breath?

    The Labrador Sea in the North Atlantic is one of the few areas in the world ocean where cold, saline seawater sinks to large depths and forms deep water. This convection process also transports oxygen into the deep sea. A team of scientists from Scripps Institution of Oceanography (San Diego, California), Dalhousie University (Halifax, Canada) and GEOMAR Helmholtz Centre for Ocean Research Kiel have now published the analysis of data obtained from the mooring K1 in the international scientific journal Geophysical Research Letters. The results show that in winter 2014/2015 an unusually high amount of oxygen was absorbed by the ocean in the region. The actual oxygen uptake at the sea surface is very difficult to determine directly, but the scientists were able to derive the oxygen uptake from the oxygen content measured throughout the water column. One of the questions the scientists were concerned with: Can the strong oxygen uptake in the Labrador Sea compensate the global oxygen loss of the ocean?

  • Diverse Landscapes Are More Productive and Adapt better to Climate Change

    The dramatic, worldwide loss of biodiversity is one of today's greatest environmental problems. The loss of species diversity affects important ecosystems on which humans depend. Previous research predominantly addressed short-term effects of biodiversity in small experimental plots planted with few randomly selected plant species. These studies have shown that species-poor plant assemblages function less well and produce less biomass than species rich systems.

  • What Happens to the Antarctic Ocean with 1 Degrees Celsius of Warming?

    Scientists have discovered “massive impacts” on marine life in the Antarctic Ocean when waters are warmed by 1 degree Celsius, including a doubling in growth of some species and a drop in overall biodiversity, according to a new study in the journal Current Biology.

  • Massive Antarctic Volcanic Eruptions Triggered Abrupt Southern Hemisphere Climate Changes Near the End of the Last Ice Age

    New findings published today in the Proceedings of the National Academy of Sciences of the United States of America (PNAS) by Desert Research Institute (DRI) Professor Joseph R. McConnell, Ph.D., and colleagues document a 192-year series of volcanic eruptions in Antarctica that coincided with accelerated deglaciation about 17,700 years ago.

  • More losers than winners for Southern Ocean marine life

    A team at British Antarctic Survey (BAS) examined the potential distribution of over 900 species of shelf-dwelling marine invertebrates under a warming scenario produced by computer models. They conclude that, while some species in some areas will benefit, 79% of the species native to the region will lose out. This has important implications for future resource management in the region.

  • Record-low 2016 Antarctic sea ice due to 'perfect storm' of tropical, polar conditions

    While winter sea ice in the Arctic is declining so dramatically that ships can now navigate those waters without any icebreaker escort, the scene in the Southern Hemisphere is very different. Sea ice area around Antarctica has actually increased slightly in winter — that is, until last year.

  • Nearly 1 Million Pounds of Seven Deadly Air Pollutants Released by Texas Refineries During Harvey Floods

    Refineries and petrochemical plants in south Texas released nearly 1 million pounds of seven especially dangerous air pollutants during flaring and chemical spills triggered by Hurricane Harvey, according to a new Center for Biological Diversity analysis of industry data.

  • NASA Examines Hurricane Lidia's Eye on the Baja

    Hurricane Lidia’s eye was visible in NASA satellite imagery as it approached Baja California, Mexico’s southernmost tip. Hurricane Lidia was making landfall on the Baja on Sept. 1 at 5 a.m. PDT and continued to bring soaking rains to the region.

  • Can corals survive climate change?

    A group of international scientists, including scientists from Australia, have issued advice that more research is urgently required to determine whether corals can acclimatise* and adapt to the rapid pace of climate change.

  • Harvey Evacuees Leave Their Blongings - And Health Records - Behind

    Digitizing the world's medical records was supposed to make doctors' lives easier, and patients' lives longer. But unlike banking and shopping, medicine has had a rough time transitioning to the new digital order. Because health care providers use different systems for their electronic health care records, it’s still difficult for a patient’s data to follow them through the medical ecosystem.
