A large-scale bloom of toxic cyanobacteria has occurred in the waters off the Baltic Sea. These algae produce hepatotoxins and neurotoxins through their metabolic processes, and contact with the contaminated seawater can easily cause physical discomfort. This summer’s high sea temperatures and prolonged sunlight, combined with large amounts of nitrogen and phosphorus nutrients carried in…

In the town of Los Osos in central California, a rupture in a sewage pipeline’s air vent caused an overflow of approximately 15,000 gallons of untreated sewage. Some of the sewage seeped into the surrounding soil before flowing into the nearshore mudflats and shallow waters of the Pacific Ocean. Concentrations of fecal coliform bacteria in…

The Tijuana River on the Mexican side continues to carry large amounts of untreated domestic sewage, industrial chemical runoff, and solid waste into the Pacific Ocean, with the maximum daily flow of sewage reaching 30 million gallons. The pollutants have formed a large-scale contaminated current that is spreading northward, continuing to affect coastal waters in…

The World Meteorological Organization has updated its global marine heatwave and red tide warnings. Sea surface temperatures in the Mediterranean, the North Atlantic, and off the coast of Australia have repeatedly broken records for this time of year. High temperatures can increase the toxicity of land-based wastewater, and the risk of red tides in North…

Several Pacific island nations have issued a joint statement strongly protesting Japan’s continued discharge of radioactive water from Fukushima into the ocean. The fishing industry is the economic and livelihood pillar upon which the residents of these island nations depend. According to ocean current simulation and monitoring data, it will take only three years for…

Monitoring along the coast of the Sea of Azov detected a strip of floating oil pollution approximately 6 kilometers long. Viscous oil was floating on the sea surface and had adhered in large quantities to nearby seaweed and coastal beaches. Local emergency response teams quickly arrived at the scene and deployed oil-absorbent materials to begin…

An international Arctic research team has released monitoring data from field samples. The study confirms that persistent synthetic organic pollutants from major industrial regions in Europe and Asia are transported over long distances across continents via atmospheric circulation and ultimately settle in Arctic snow. Due to ongoing global warming, Arctic snow is melting at an…

Australia’s marine regulatory agency issued an official penalty notice regarding a mercury leak from a process pipeline at the Ixus offshore oil and gas field, operated by Japan’s Inpex Corporation. The leak resulted in a large volume of mercury-contaminated waste liquid being discharged directly into the tropical waters off northern Australia. On-site tests showed that…

URC, a major local sugar company in the Philippines, continuously discharged untreated wastewater from ethanol fermentation—specifically distillers’ grains—into the Tanawan Strait Marine Protected Area for a period of nine months. Data from scientific field surveys show that 69% of the coral in the reserve has died off over large areas, coastal seagrass beds are rapidly…

In the early hours of July 6, Tokyo Electric Power Company (TEPCO) officially began the 21st round of discharging contaminated water from the Fukushima nuclear plant into the ocean. This discharge cycle will end on July 24, with an estimated 7,800 metric tons of contaminated water to be released. Including this round, the cumulative total…
