“FILM: Study shows how diving mammals evolved underwater endurance” from Liverpool
Scientists have explained how marine mammals are able to stay deep underwater for longer periods of time. They found that the electrical charge on myoglobin (the oxygen-binding protein that gives red meat its color) increases in those diving mammals.
Canadian researcher Thierry Chopin is working to develop less expensive technology to clean up fish farms operating in coastal waters. The idea is that the waste generated by one farm (like salmon) would be used by other seafood commodities, like shellfish. Listen to the whole story to learn more!
A new study reveals that the amount of energy available for planktivorous organism has declined in the northern Baltic Sea since the late 1970s. The researchers found that the food quality of phytoplankton and the size of zooplankton have decreased, probably due to a combination of climate change, overfishing and other environmental factors. These changes also mean that there is less food available for fish higher on the food chain.
“Ocean tours from the comfort of a classroom may soon be reality in UAE” from The National
An educational program that uses a network of underwater cameras is bringing the underwater world to students in classrooms in the UAE. There are already cameras located in U.S. and Caribbean waters and if enough people show interest, some will be installed in the UAE.
“Study of oceans’ past raises worries about their future” from McGill (link no longer active)
An international research team recently completed the first global study of how the nitrogen cycle in the ocean is changing. They found that the oceans are good a balancing the nitrogen cycle, but it is a slow process that can take centuries at the least. Nitrogen is crucial to the health of our oceans and changes in the cycle will impact marine life.
“Submersible Jiaolong sets sail for deep-sea mission” from Xinhua? News
China’s manned submersible, Jiaolong, is ready for a deep-sea mission in the South China Sea. The scientists on board are looking to collect data on the sea’s currents and the local marine life.
