Sailors have been seeing a strange glowing ocean phenomenon called “milky seas” for over 400 years, especially in the Arabian Sea. Recent research has gathered more than 400 sightings into a new database, which helps scientists predict when these bioluminescent events might happen. Justin Hudson, a doctoral student at Colorado State University, leads this study and hopes the database will answer questions about the occurrence of milky seas and their ecological effects. These events can last for months and cover areas up to 100,000 square kilometers, likely caused by high levels of bioluminescent bacteria like Vibrio harveyi. The research also links milky seas to global climate events, such as the Indian Ocean Dipole and El Ni\u00f1o. Unlike other bioluminescent events caused by dinoflagellates, which glow blue when disturbed, milky seas emit a steady glow. Professor Steven Miller, a coauthor of the study, noted that the bacterial population reacts dramatically during these events, raising questions about their impact on marine food chains and the carbon cycle.<\/p>\n","protected":false},"author":15,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"summary":"Sailors have long reported the mysterious \"milky seas,\" glowing expanses of ocean, particularly in the Arabian Sea. Recent research has compiled over 400 sightings into a new database, enhancing predictions of these rare bioluminescent events. Scientists are investigating the ecological implications and the role of bioluminescent bacteria, specifically Vibrio harveyi, in these phenomena.\n\nThe glowing waters, described as bright enough to read by, can span up to 100 mil quil\u00f4metros e s\u00e3o vis\u00edveis do espa\u00e7o. While the exact causes remain elusive, researchers suggest that these occurrences may indicate the health of marine ecosystems. The new database aims to facilitate further studies, potentially revealing how climate change impacts these events and the broader oceanic food chain.\n\nDr. Steven Miller, coautor do estudo, destaca que a compreens\u00e3o dos \"milky seas\" pode esclarecer quest\u00f5es sobre a vida marinha e o ciclo do carbono.
