Understanding the conditions that foster coral reefs’ caretaker fishes

Plant-eating fish control the spread of seaweed and algae on coral reefs. New research explaining why populations of these fish vary from site to site could lead to better reef protection strategies.
Many seabird species, including the blue petrel (Halobaena caerulea), consume plastic at sea because algae on the plastic produce an odor that resembles their food sources. J.J. Harrison

The oceans are full of plastic, but why do seabirds eat it?

Thousands of seabirds die every year from consuming plastic trash in the oceans. But why do they eat plastic? New research shows that it produces odors that help some species find prey.

Underwater robots help scientists see where marine larvae go and how they get there

Most ocean species start out as larvae drifting with currents. Using underwater robots, scientists have found that larvae use swimming motions to affect their course and reach suitable places to grow.

It’s time to speak up about noise pollution in the oceans

We tend to think of the oceans as quiet, when in fact they're anything but. Noise is the "forgotten pollutant", but the good news is that unlike many other pollutants it can be switched off if we try.

Oil, gas and marine parks really can coexist in our oceans – here’s how

Marine parks need to cover large swathes of ocean, but they also need to cover the right areas if they are to deliver the best conservation. New research off Australia's northwest suggests how.
