Why SEA turn GREEN | Rare Phenomenon | Cargo Ship Secrets | Life at Sea

“Ever wondered why the sea keeps changing colours? 🌊 As a Chief Officer, I see this every single day. Deep blue in open ocean, green near shallow patches, brown near river discharge, and grey when the weather turns bad. Each colour tells a story — depth, algae, sediment, sunlight, currents… everything plays a role. Sea isn’t just water… it’s a moving map if you know how to read it.” #marinefacts #oceanscience #secrets #oceanlife #SailorsOfInstagram [ ocean facts, sea mystery, merchant navy life, seafarer stories, cargo ship vlog, ocean phenomenon, ocean secrets, deep blue water, green sea water ]
