Plastic soup: check the global count density in four size classes | Illustration: 5 Gyres

A study by 5 Gyres reveals that there are 270,000 metric tonnes of plastics floating in all of the world's oceans.

Plastics are ruling our seas and oceans. A team of researchers led by Marcus Eriksen, co-founder of 5 Gyres, used an oceanographic model to calculate a total of 5.25 trillion particles weighing 268,940 tons floating over salted water.

5 Gyres also compared plastic pollution levels between oceans and across four size classes: 0.33–1.00 mm (small microplastics), 1.01–4.75 mm (large microplastics), 4.76–200 mm (mesoplastic), and >200 mm (macroplastic).

Turtle Bay Resort: Stoke Certified | Photo: Turtle Bay Resort

Oahu's Turtle Bay Resort has been awarded with "Stoke Certified", the world's first sustainability certification program to focus exclusively on surf and snow resorts.

The onsite evaluation of Turtle Bay Resort analyzed 142 criteria and 326 sustainability indicators resulting in a compliance score of 83%. It is now the second surf resort in the world, and the first in Hawaii, to be awarded the sustainable certification.

"Over the past year, we've collaborated with Stoke to further our master plan for the benefit of all guests who seek a resort experience that is in keeping with the spirit of the North Shore," explains Scott McCormack, vice president of Turtle Bay Resort.

Antarctic glaciers: melting from below | Photo: Geomar: melting from below | Photo: Geomar

Scientists at the Geomar Helmholtz Centre for Ocean Research Kiel have concluded that water temperatures on the West Antarctic shelf are rising predominantly due to warm water from greater depths.

Data collected by the German marine researchers, alongside colleagues of the University of East Anglia, the California Institute of Technology and the University of Hokkaido (Japan), confirms that these events will accelerate the glacier melt from below and trigger the sliding of big glaciers.

"If the water continues to warm, the increased penetration of warmer water masses onto the shelf will likely further accelerate this process, with an impact on the rate of global sea level rise," explains Professor Karen Heywood from the University of East Anglia.
