Marine Drive

Industry commentary is asking whether artificial intelligence can improve wildlife detection around tidal energy installations, a key environmental challenge for marine renewable projects. Monitoring marine mammals and fish near tidal turbines is difficult, and automated detection could help operators reduce risks to sea life while keeping projects viable. The debate highlights growing interest in AI tools for environmental monitoring in the renewable energy sector.

Marine records have been broken along the entire California coast, with El Niño conditions cited as the driving force. The phenomenon, marked by unusually warm ocean waters, is affecting sea temperatures and marine life from north to south along the state's shoreline. Observers are watching closely, as El Niño years often bring ecological shifts, unusual wildlife sightings, and broader implications for fisheries, coastal weather patterns, and storm activity across the Pacific.

Researchers at UC Davis have published work explaining how crushed shells can protect marine environments against ocean acidification. As oceans absorb more carbon dioxide, their chemistry shifts in ways that harm shellfish and other marine life. The study suggests adding crushed shell material can buffer acidic seawater locally, offering a potential tool for coastal restoration efforts.

Blue whales that normally frequent waters off the Galápagos Islands have disappeared, and researchers say they cannot currently locate them. Scientists suspect the El Niño climate pattern may be driving the whales elsewhere, likely by altering ocean temperatures and the food supply. The development has drawn attention from marine biology enthusiasts concerned about the species and the wider effects of a warming ocean on marine life.

An ancient Indigenous practice is being studied as a potential way to help marine life survive increasingly acidic oceans. Ocean acidification, driven by rising carbon dioxide emissions, threatens shellfish, corals and other sea creatures, and researchers are revisiting traditional knowledge for low-cost solutions to buffer coastal waters. Details of the practice and its measured effectiveness remain sparse in early coverage.

New findings challenge a long-standing assumption in oceanography that organic matter in marine phytoplankton follows a fixed elemental ratio. Researchers say the internal chemical composition of these microscopic organisms, which anchor ocean food webs and drive carbon cycling, is far from uniform. The insight could change how scientists estimate ocean respiration and model the marine carbon cycle.

New research examines how bacteria interact with seagrass meadows and influence carbon cycling in the ocean. The findings highlight seagrass ecosystems as significant carbon stores, with microbial activity playing a key role in how carbon is captured and retained in marine sediments. The work adds to growing scientific interest in blue carbon habitats and their potential in climate mitigation efforts.
