Plastic within the Great Pacific Garbage Patch is ‘increasing exponentially,’ scientists find That’s the title of a new Washington Post article, written by Chris Mooney. He explains, the results of a new study. Seventy nine thousand tons of plastic debris, in the form of 1.8 trillion pieces, now occupy an area three times the size…

There are 32 million gallons worth of mercury, or the equivalent of 50 Olympic swimming pools, trapped in the permafrost. For context, that’s “twice as much mercury as the rest of all soils, the atmosphere, and oceans combined. And it could be released. https://www.washingtonpost.com/news/energy-environment/wp/2018/02/05/the-arctic-is-full-of-toxic-mercury-and-climate-change-is-going-to-release-it Ambarchik: Research on permafrost at the Siberian arctic coast https://www.youtube.com/watch?v=ZhGcJnRgzy4 Permafrost…
The Oceans Melting Greenland mission seeks to understand how ocean water is contributing to ice loss in Greenland. In October 2017, mission scientists and crew dropped 240 ocean probes from a C-130 aircraft into the waters around Greenland to measure ocean temperature. Footage includes interior and exterior shots of the aircraft with crew and scientists…

In this lecture by Alex Thomas, he explains how does carbon dioxide interact with water and why the ocean can store so much carbon. What is the effect on the ocean’s pH and how does this in turn determine how much carbon the ocean can store.
Pacific island nations could lose between 50 and 80 percent of their fish species by the end of the century if climate change continues unabated. https://www.radionz.co.nz/international/programmes/datelinepacific/audio/2018622497/climate-change-could-kill-50-80-of-pacific-fish-species-study

Researchers studying a rapid global warming event, around 56 million years ago, have shown evidence of major changes in the intensity of rainfall and flood events. The findings indicate some of the likely implications should current trends of rising carbon dioxide and global warming continue. https://scienmag.com/new-research-indicates-likely-hydrological-implications-of-rapid-global-warming
Greenpeace was inspired by Coca Cola’s Christmas video, and created a remake! Studies show that up to 90% of seabirds now have plastic in their stomachs. We need to act urgently to stop plastic getting into our oceans. And we’re calling on Coca Cola – the world’s biggest soft drinks company – to lead the…

NASA 2012: The transpolar drift (purple arrows) is a dominant circulation feature in the Arctic Ocean that carries freshwater runoff (red arrows) from rivers in Russia across the North Pole and south towards Greenland. Under changing atmospheric conditions, emergent circulation patterns (blue arrows) drive freshwater runoff east towards Canada, resulting in freshening of Arctic water…

Film about GEOSECS, the Geochemical Ocean Sections Study, a global survey of the three-dimensional distribution of chemical, isotopic and radiochemical tracers in the ocean. George Veronis of Yale University speaks about models for ocean layers and circulation in the world ocean, and data gathering by R.V. Melville (SIO) and R.V. Knorr (WHOI). Extensive footage onboard…
