Microplastics found in Arctic sea ice

The video discusses a Swedish icebreaker expedition through the Northwest Passage, which discovered microplastics in Arctic ice. Researchers used helicopters and drills to collect ice core samples, revealing various shapes and sizes of plastic particles. The team aims to understand the impact of these particles on Arctic wildlife. A related study found microplastics in Arctic sea ice and water, suggesting wind as a transport mechanism.
