Climate change to drive increasing overlap between Pacific tuna fisheries and emerging deep-sea mining industry

In ocean areas beyond national jurisdiction, various legal regimes and governance structures result in diffused responsibility and create challenges for management. Here we show those challenges are set to expand with climate change driving increasing overlap between eastern Pacific tuna fisheries and the emerging industry of deep-sea mining. Climate models suggest that tuna distributions will shift in the coming decades.

Extent and reproduction of coastal species on plastic debris in the North Pacific Subtropical Gyre

We show that the high seas are colonized by a diverse array of coastal species, which survive and reproduce in the open ocean, contributing strongly to its foating community composition. Analysis of rafting plastic debris in the eastern North Pacifc Subtropical Gyre revealed 37 coastal invertebrate taxa, largely of Western Pacifc origin, exceeding pelagic taxa richness by threefold. Coastal taxa, including diverse taxonomic groups and life history traits, occurred on 70.5% of debris items.

The Great Pacific Garbage Patch is now so huge and permanent that a coastal ecosystem is thriving on it, scientists say

Scientists have found thriving communities of coastal creatures, including tiny crabs and anemones, living thousands of miles from their original home on plastic debris in the Great Pacific Garbage Patch – a 620,000 square mile swirl of trash in the ocean between California and Hawaii.
