  • To float or not to float? Mystery solved as to why algae balls float and sink
    on August 20, 2018 at 3:30 pm

    Scientists have uncovered the age-old mystery of why marimo algae balls sink at night and float during the day. […]

  • Acid coastal seas off US putting common fish species at risk
    on August 18, 2018 at 3:58 pm

    Scientists have shown that coastal waters and river estuaries can exhibit unique vulnerabilities to acidification than offshore waters. This acidification, detected in waters off the United States West Coast and the Gulf of Mexico, can lead to disorientation and cognitive problems in some marine fish species, such as salmon, sharks, and cod. […]

  • Making aquafeed more sustainable: Scientists develop feeds using a marine microalga co-product
    on August 18, 2018 at 3:56 pm

    Scientists have created a more sustainable feed for aquaculture by using a marine microalga co-product as a feed ingredient. The study is the first of its kind to evaluate replacing fishmeal with a co-product in feed designed specifically for Nile tilapia. […]

  • Old species learn new tricks...very slowly
    on August 15, 2018 at 9:11 pm

    No species lasts forever, and, just as the saying goes, it seems like old species may get stuck in their ways and can't adapt to environmental change as fast as younger species do. […]

  • When viruses infect phytoplankton, it can change the clouds
    on August 15, 2018 at 5:05 pm

    Microscopic plant-like organisms called phytoplankton support the diversity of life in the ocean. Scientists now report that one species, Emiliania huxleyi, and a virus closely associated with it, might be responsible for changes in cloud properties as well. When infected, E. huxleyi releases its chalky shell into the air, where it acts as an aerosol reflecting sunlight and even affecting cloud creation and movement. […]

  • Apathy towards poachers widespread in world's marine protected areas
    on August 15, 2018 at 2:29 pm

    A new study has found that nearly half of fishers from seven countries had witnessed someone poaching in marine protected areas in the past year and most of them did nothing about it. […]

  • Arctic seabird populations respond to climate change
    on August 15, 2018 at 1:15 pm

    Seabirds such as gulls can be key indicators of environmental change as their populations respond to shifts in their ocean habitat over time. A new study investigates how several species have responded to changing environmental conditions in the Arctic over the last four decades. The authors find that a warming ocean is directly and indirectly affecting seabird populations in Alaska. […]

  • Glacier depth affects plankton blooms off Greenland
    on August 14, 2018 at 2:14 pm

    The unusual timing of highly-productive summer plankton blooms off Greenland indicates a connection between increasing amounts of meltwater and nutrients in these coastal waters. Researchers now show that this connection exists, but is much more complex than widely supposed. Whether increasing meltwater has a positive or negative effect on summertime phytoplankton depends on the depth at which a glacier sits in the ocean. […]

  • Young salmon may leap to 'oust the louse'
    on August 13, 2018 at 2:03 pm

    A study by aquatic ecologists reveals that young salmon may jump out of water to remove sea lice. […]

  • Sea stars critical to kelp forest resilience
    on August 13, 2018 at 2:03 pm

    A study by a resource and environmental management researcher reveals that sunflower sea stars play a critical role in the resilience of B.C.'s kelp forests, which are among the most productive ecosystems on Earth. Similar to land-based forests, kelp forests provide essential habitat for species and also help remove CO2 from the atmosphere. […]

  • Marine mammals lack functional gene to defend against popular pesticide
    on August 9, 2018 at 6:12 pm

    As marine mammals evolved to make water their primary habitat, they lost the ability to make a protein that defends humans and other land-dwelling mammals from the neurotoxic effects of a popular human-made pesticide. The implications of this discovery led researchers to call for monitoring our waterways to learn more about the impact of pesticides and agricultural run-off on marine mammals, such as dolphins, manatees, seals and whales. […]

  • Diverse symbionts of reef corals have endured since 'age of dinosaurs'
    on August 9, 2018 at 6:11 pm

    Coral-algal partnerships have endured numerous climate change events in their long history, and at least some are likely to survive modern-day global warming as well, suggests an international team of scientists. […]

  • 'Biological passport' to monitor Earth's largest fish
    on August 9, 2018 at 1:34 pm

    Whale sharks, the world's largest fish, roam less than previously thought. This new study used stable isotope analysis to demonstrate that whale sharks feeding at three disparate sites in the Western Indian Ocean and Arabian Gulf rarely swim more than a few hundred kilometers north or south from these areas according to researchers. […]

  • Effective method to control algae growth on Hawaiian coral reefs
    on August 8, 2018 at 11:36 pm

    Researchers have found a management approach that combining manual removal and outplanting native urchin was effective at reducing invasive, reef smothering macroalgae by 85 percent on a coral reef off O'ahu, Hawai'i. […]

  • Models may help reduce bycatch from longline fishing
    on August 8, 2018 at 7:34 pm

    Hundreds of thousands of sharks, sea birds and other marine species are accidentally killed each year after becoming snagged or entangled in longline fishing gear. New models may help reduce the threat by giving regulatory agencies a new tool to predict the month-by-month movements of longline fleets on the high seas and determine where and when by-catch risks are greatest. […]

  • New species of rare ancient 'worm' discovered in fossil hotspot
    on August 8, 2018 at 5:42 pm

    Scientists have discovered a new species of lobopodian, an ancient relative of modern-day velvet worms, in 430 million-years-old Silurian rocks in Herefordshire, UK. […]

  • Expedition probes ocean's smallest organisms for climate answers
    on August 8, 2018 at 5:41 pm

    In August a team of scientists is sailing 200 miles to the northeastern Pacific Ocean with advanced robotics and other instruments on a month-long quest to investigate plankton and their impact on the carbon cycle. […]

  • Good news for fishermen: Browning impacts fish less than expected
    on August 8, 2018 at 1:37 pm

    Water color is getting darker in lakes across the planet. This phenomenon, known as 'browning,' was anticipated to cause widespread declines in fish populations. A new study finds that the number of fish populations impacted by browning is smaller than previously believed. […]

  • Baby sea snails ride waves into shallower waters
    on August 7, 2018 at 2:06 pm

    The warming ocean may cause the larvae of bottom-dwelling snails to hatch earlier in the spring, when waves are larger, potentially impacting their ability to survive and serve as food for other sea creatures. A new study sheds new light on the sensory organs the snail larvae use to feel -- and perhaps even hear -- whether the water is turbulent or wavy, and improve their odds of being carried to a good habitat where they can settle down as adults. […]

  • Corals are becoming more tolerant of rising ocean temperatures
    on August 7, 2018 at 1:51 pm

    Scientists replicate landmark study to determine changes in coral sea temperature tolerance over time. In the three species of Hawaiian corals retested, bleaching occurred later, with higher survivorship and growth rates than the same species of corals in 1970. However, scientists warn that temperatures are rising faster than corals can change. […]
