Plastic Waste In Antarctica

Plastic waste and toxic chemicals found in remote parts of the Antarctic this year add to evidence that pollution is spreading to the ends of the Earth, environmental group Greenpeace said.

Microplasticstiny bits of plastic from the breakdown of everything from shopping bags to car tires – were detected in nine of 17 water samples collected off the Antarctic peninsula by a Greenpeace vessel in early 2018, it said. And seven of nine snow samples taken on land in Antarctica found chemicals known as PFAs (polyfluorinated alkylated substances), which are used in industrial products and can harm wildlife.

 We may think of the Antarctic as a remote and pristine wilderness,” Frida Bengtsson of Greenpeace’s Protect the Antarctic campaign said in a statement about the findings. But from pollution and climate change to industrial krill fishing, humanity’s footprint is clear,” she said. “These results show that even the most remote habitats of the Antarctic are contaminated with microplastic waste and persistent hazardous chemicals.”

The United Nations’ environment agency says plastic pollution has been detected from the Arctic to Antarctica and in remote places including the Mariana Trench, the deepest part of the world’s oceans in the Pacific.

UN agency said that less than a 10th of all the plastic ever made has been recycled, and governments should consider banning or taxing single-use bags or food containers to stem a tide of pollution.

Project To Map Ocean Floor By 2030

Set to map the entirety of the global ocean floor by 2030, the Nippon Foundation-GEBCO Seabed 2030 Project has started operations, based on a seed money pledge of US$2 million-per-year from the Japan-based Nippon Foundation.

Officially launched during the United Nations Ocean Conference (5-9 June 2017) in New York, the project draws on the experience of international organizations and mapping experts under the coordination of UNESCO’s Intergovernmental Oceanographic Commission (IOC) and the International Hydrographic Organization (IHO).

Having a comprehensive map of the ocean floor could assist global efforts to combat pollution, aid marine conservation, forecast tsunami wave propagation, and help inform the study of tides and wave action. It could also help in search and rescue operations, as in the disappearance of the MH370 Malaysian Airlines flight in March 2014.

Despite its obvious useful applications, detailed bathymetric data – the topography of the ocean floor – is still missing for much of the global ocean. More than 85% of the world ocean floor remains unmapped with modern mapping methods, and by any technological standards we know more about Mars than we do about the depths of the ocean.
