China Maritime Report No. 3: China’s Distant-Ocean Survey Activities

Astronomers may have found traces of dimethyl sulfide (DMS) on K2-18b. On Earth, this molecule is only produced by life, specifically marine phytoplankton. However, researchers remain cautious as unknown chemical processes could also explain it. Other Candidates: Distant Ocean

This is the most famous candidate. Scientists at the University of Cambridge have detected methane and carbon dioxide in its atmosphere, suggesting a hydrogen-rich environment and a potentially massive liquid ocean. China Maritime Report No

These missions collect "bathymetric" data (sea depth and contours) and meteorological info. This is critical for undersea warfare , as temperature and salinity data help submarine commanders elude detection and improve sonar performance. specifically marine phytoplankton. However
