    NASA has launched one of its most crucial science missions to date, the Mars  2020 mission that carries its Perseverance robotic rover. This rover, a successor to the Curiosity robotic explorer, is equipped with sensors specifically designed to help it hopefully fund evidence of ancient, microbiotic life on Mars. Mars 2020 departed from Cape Canaveral in Florida at 7:50 AM EDT (4:50 PM PDT). Perseverance was loaded atop a United Launch Alliance (ULA) Atlas V rocket, which had a good liftoff

    Historic carbon dioxide decline could hold clues for future climate

    A new study led by researchers at The Australian National University (ANU) provides a clearer snapshot of conditions during the last ice age—when global ice sheets were at their peak—and could even lead to better models for future climate projections.   The study demonstrates a new way of recreating ocean conditions in the Atlantic during the Last Glacial Maximum (LGM)—around 20,000 years ago.   Lead author Dr. Jimin Yu says scientists have been trying to reconstruct ocean ci

    Scofflaw ships hauled in more than 176,000 tons of Pacific flying squid in North Korean waters in 2017 and 2018. A 55- to 60-meter lighting vessel of Chinese origin near North Korean waters. This vessel had its four arm-like structures deployed and flew both North Korean and Chinese flags.   Satellite imagery has dragged "dark" fishing fleets out into the light.   Orbital observations have revealed extensive illegal fishing of Pacific flying squid (Todarodes pacificus) i

    Marine Species are Shifting Towards the Poles

    By Lurker,
    Global warming has caused a shift in species’ ideal habitats, prompting everything from mushrooms to trees, mammals to amphibians and other terrestrial species to seek out different ecological zones in which to thrive. New research is collecting data on marine species that are also experiencing climate related habitat migrations in greater numbers than scientists anticipated. As species’ normal habitats are becoming warmer, habitat is lost due to human infrastructure, or habitats are becomi

    UrsaNav installs eLoran testbed in South Korea

    By Lurker,
    South Korean is in the early stages of evaluating its eLoran system, but great results are expected based on the UrsaNav-supplied station in Incheon. In August 2018, the Korea Research Institute of Ships and Oceans Engineering (KRISO) awarded UrsaNav, through its agent Dong Kang M-Tech, a contract to supply and install an eLoran transmitter testbed system in South Korea. UrsaNav is the exclusive, worldwide distributor of Nautel’s NL Series transmitters, provided eLoran transmitter tec
