Thwaites Glacier: melting fast

The West Antarctic Ice Sheet, which holds enough water to raise global seas by several feet, is about to collapse, according to scientists from the University of Washington.

Kelp: still no signs of Fukushima radiation

The first collection of kelp samples along the western US coastline revealed no signs of ocean-borne radiation from Japan's Fukushima nuclear power plant disaster.

"Our data does not show the presence of Fukushima radioisotopes in West Coast Giant Kelp or Bull Kelp," Steven Manley, marine biology professor at California State University, Long Beach (CSULB).
