New laser technology is allowing MBARI scientists to look into the structure of giant larvaceans–tadpole-like marine animals that are important players in ocean ecosystems. In a recent paper in Science Advances, MBARI researchers described a new method for measuring the flow of seawater through larvaceans and other gelatinous animals. The results will help scientists understand how much carbon dioxide the oceans are absorbing from the atmosphere. Larvaceans play a significant role in moving carbon from the upper part of the ocean down into the deep sea. They build balloon-like mucus structures

Further Milestones for QuietSea PAM System

 Sercel said its QuietSea Passive Acoustic Monitoring (PAM) system, which is seamlessly integrated into seismic streamers to detect the presence of marine mammals during seismic operations, has passed two milestones.   Most recently, the U.S. Bureau of Safety and Environmental Enforcement (BSEE) authorized the use of QuietSea for seismic survey operations in the U.S. waters of the Gulf of Mexico. The U.S. authorities recognized that the ability to use geophysical survey streamers for PAM was a great step in the future development of effective PAM systems.   Another milestone was
