The Global Reef Expedition: Kingdom of Tonga
kinds of fish seen on reefs in Tonga, the fish were small. Few large and commercially valuable fish remained. But with continued fisheries management, there is hope these reefs can recover.“The coral reef fish communities we observed in Tonga were dominated by small fish considered low on the food chain, raising concern for the long-term sustainability of the fishery,” said Renee Carlton, author and Marine Ecologist for the Foundation. “We saw very few fish that are particularly important to local fishers, such as parrotfish, emperors, snapper, and groupers. Our findings highlight

, with what he did with Lindblad Travel.”The renowned adventure-travel pioneer, Lars Lindblad, led the first laymen traveler groups to the Galapagos, Antarctica and other regions, all of which need careful care for future generations.“Think about coral reefs disappearing entirely, the whole food chain of the ocean interrupted and ceasing to function,” he said. “That’s scary, motivating stuff. The greatest wonder on earth are coral reefs. The temperature of the world is heating up, and our environment is threatened by that. Coral reefs depend on water temperatures that don&rsquo
Full-Depth Current Profiling Around the Global Ocean
ADCPs (LADCP) have provided well-resolved, full-depth current profiles since the early 1990s.Deep currents store, carry, and redistribute important properties for life in and out of the sea. For example, oxygen and nutrient levels are vital where the deep waters upwell to supply the ocean’s food chain. Yet until the mid-1970s, deep currents rivaled the dark side of the moon for mystery. Stimulated by findings from improved observations, there is now intense interest in how deep currents take part in the global climate system. Especially important are the changing heat and CO2 content of the

Environment Programme.The latest example was a pilot whale that died in Thailand with some 80 pieces of plastic rubbish found in its stomach.The theme of World Environment Day on Tuesday is beating plastic pollution, with a call for citizens, companies and civil society groups
Efforts to Curb Plastic Litter in Oceans are Working

United Nations figures show 8 million tonnes of plastic - bottles, packaging and other waste - enter the ocean each year, killing marine life and entering the human food chain. Scientists have urged tougher restrictions on plastic waste. In December, almost 200 nations agreed to limit plastic pollution of the oceans, warning it could outweigh fish by 2030. In contrast to plastic bags, the researchers found the amount of plastic fishing debris - including
Britain Bans Microbeads; Lawmakers Urge More Action on Plastic
, face washes and shower gels that end up in the oceans, will come into force in Britain on Tuesday, but lawmakers said more needed to be done to tackle plastic pollution. The tiny plastic beads pollute waterways and oceans, where they can be eaten by marine life and end up in the human food chain. A report by lawmakers in 2016 said the industry’s commitment to phasing them out was inconsistent and recommended a ban. “Microbeads in cosmetics are an avoidable part of the problem, which is why we called for a ban,” member of parliament Mary Creagh, chair of the Environmen

;Today, it is estimated that 23,000 kilos of plastics are dumped into the world’s oceans every single minute,” said Thomas van Thiel, By the Ocean we Unite. “These materials are fragmenting into ever smaller particles, damaging the marine environment and marine life, and entering the food chain. Plastics also act as sponges to other toxic chemicals already in the seas, concentrating areas of pollution. Removing plastics from the oceans is not currently feasible, but we must identify sources and effects because prevention is not only the better option, but cheaper than cleaning the oceans
