Beyond the Edge of the Sea Traveling Art Exhibition
‘Beyond the Edge of the Sea’ is an exhibition of the work of scientific illustrator Karen Jacobsen. She has accompanied Dr. Cindy Lee Van Dover of Duke University in the […]
2 PhD Student and 2 Postdoctoral Researcher Positions- Hydrothermal Activity on the Mid-Cayman Spreading Center
Starting January 1, 2009, a new 4-year program will investigate hydrothermal systems on the Mid-Cayman Spreading Center (MCSC) under NASA’s ASTEP program – a joint collaboration between Woods Hole Oceanographic […]
Marine Subsurface is a Distinct Microbial Habitat
Researchers from NAI’s Penn State, MBL, and UCLA Teams have completed a study of the subseafloor marine biosphere, which may be one of the largest reservoirs of microbial biomass on […]
Seafloor Microbes Abundant and Thriving … An Alternative Cradle for Life?
Researchers from NAI’s Marine Biological Laboratory Team continue their study of the deep biosphere, reporting the latest results in Nature. This new study reveals that bacterial communities dwelling on ocean-bottom […]
