Bloom with a view as pilot spots algae off coast.
A photographer captured this huge algae bloom off the Welsh coast.
John Bulpin, from Swansea, was flying his plane off the coast of Port Talbot on Sunday at around 11.30am.
He thought it could have been pollution, so reported it to Natural Resources Wales.
The body has confirmed they believe it is algal blooms, which could be linked to the bioluminescent plankton seen at Southerndown, Aberavon and Three Cliffs Bay in recent weeks.
But they say that without a sample, which will be difficult to obtain unless the algae come ashore, it is impossible to say for certain what type of algae/phytoplankton they are.
A spokesman said: "We believe that the images show algal blooms, with surface scums of the scale shown often associated with mixed diatom blooms at this time of year. Likely species are Rhizosolenia spp and Thalassiosira spp. "The patterns formed on the water surface are likely to be due to the effects of the tide, wind and associated surface currents," he continued.
"It was spectacular from the air," Mr Bulpin said.
