Mixing iron into the north Pacific stirs geo‑engineering controversy
A British Columbian fishing community has drawn almost universal condemnation after dumping 100 tonnes of iron rich dust into the ocean to stimulate a plankton bloom, in an effort to restore salmon numbers…
Hooked on tuna: People have been harvesting these ocean predators for 44,000 years

Tiny marine plants face a mixed bag thanks to climate change
You may not have heard of them or given them much thought, but phytoplankton — the microscopic plants that grow throughout the world’s oceans — are the foundation of oceanic food webs. Although tiny, they…
Ocean debris leads the way for castaway fisherman
The fisherman who washed up on the Marshall Islands last weekend was very lucky to have stranded on a remote beach there. The currents in the Pacific Ocean would have inevitably taken him into the great…
Leave the ocean garbage alone: we need to stop polluting first
Recent plans to clean plastics from the five massive ocean garbage patches could do more damage to the environment than leaving the plastic right where it is. There is no doubt that the focus on cleaning…
The way the wind blows may not be enough to prevent ocean ‘dead zones’ growing
The world’s oceans are plagued with the problem of “dead zones”, areas of high nutrients (such as nitrogen and phosphorus) in which plankton blooms cause a major reduction of oxygen levels in the water…
