Magnetic effect on CO 2 solubility in seawater: A possible link between geomagnetic field variations and climate

(August 2008)

Correlations between geomagnetic-field and climate parameters have been suggested repeatedly, but possible links are controversially discussed. Here we test if weak (Earth-strength) magnetic fields can affect climatically relevant properties of seawater. We found the solubility of air in seawater to be by 15% lower under reduced magneticfield (20 mT) compared to normal field conditions (50 mT). The magnetic-field effect on CO2 solubility is twice as large, from which we surmise that geomagnetic field variations modulate the carbon exchange between atmosphere and ocean. A 1% reduction in magnetic dipole moment may release up to ten times more CO2 from the surface ocean than is emitted by subaerial volcanism.

Four more Northern Californians named as victims in Conception dive boat fire

Carrie McLaughlin and Kristian Takvam, coworkers who lived in Northern California, were on the Conception, which was anchored in Platt’s Harbor off Santa Cruz Island when it became fully engulfed in flames as passengers slept below deck.

They both worked for San Francisco-based Brilliant, a website that creates interactive science, technology, engineering and mathematics courses. McLaughlin was a senior software engineer and Takvam was vice president of engineering.

Governor Newsom Responds to Developments in Conception Boat Fire Investigation

We are saddened to learn that Adrian Dahood-Fritz, who worked for the Ocean Protection Council under the California Natural Resources Agency since April as a senior environmental scientist, and her husband Andrew Fritz, were aboard the boat and are presumed dead. Adrian led the state’s efforts to manage California’s network of marine protected areas, and she cared deeply about the ocean and biodiversity. She embodied marine conservation and was a highly accomplished and respected scientific researcher.
