  • New Research Documents Environmental Change Through Dolphin Skin Cells

    “We documented for first time marked changes in the pelagic food web length in response to various natural and anthropogenic related stressors,” said lead author Rocio I. Ruiz-Cooley, formerly of NOAA Fisheries’ Southwest Fisheries Science Center and now at Moss Landing Marine Laboratories. “This tells us that the food web is very dynamic, and reveals changes with the ecosystem around it.”

  • “Blue Planet II” Tackles Plastic Pollution

    Humans are already eating plastic from the sea too. The average person who eats seafood swallows up to 11,000 pieces of microplastic every year, according to a study by researchers at the University of Ghent. As Prince Charles put it at a recent Our Ocean summit, “plastic is very much on the menu”.

  • UAE Calls for Improving Marine Environment

      Though scientists have long been sounding the alarm over the environment some people refuse to listen. Many countries have introduced environmental policies and series of initiatives to raise awareness at community level, but the journey to environmental awareness and… Read More ›

  • Alaska & Oyster Larvae in an Acidified Ocean

    As the Pacific Ocean acidifies—a consequence of carbon emissions—oyster farms off California, Washington State, and British Columbia have struggled to get larvae to grow into seed, the stage when young oysters’ shells have formed. Though scientists are not quite sure why, the water off Southeast Alaska hasn’t seen the same deleterious effects. Now, entrepreneurs and investors are eyeing the state, looking to turn a profit off the short-lived gains of climate change.

  • Hypoxia Threatens Oregon’s Shores

      Once rare, Oregon now has a regular hypoxia season — low-oxygen episodes in near-shore ocean waters — analogous to the wildfire threat that visits the state’s forests every year, scientists say. “It’s been much more prevalent over the past… Read More ›

  • Plastics Found Near North Pole

    More than five trillion pieces of plastic are estimated floating on the surface of the world’s oceans. It has been claimed that there is now enough plastic to form a permanent layer in the fossil record.

  • A Review of Climate Change & Oceans

    Another reason global warming has not been too bad yet is because the ocean absorbs most of the earth’s excess heat. But oceans are warming due to greenhouse gas emissions. According to the National Oceanic and Atmospheric Administration, half of the increase in ocean heat content since 1865 has occurred over the past two decades. Warmer water holds less oxygen, but the respiration rate of animals (except for marine mammals) increases with temperature, so they need more oxygen at the same time that less is available. A warmer ocean has less turnover (vertical water movements), which normally brings nutrient-rich water up from deep water to the plankton that photosynthesize near the surface. With fewer nutrients, they photosynthesize less and animals can’t get enough food.
