CITY marine scientists have moved to allay fears of pollution in Plymouth Sound and areas of the foreshore.

Over the past week brown scum has been reported in the sea by members of the public worried that it could be oil.

  1. Discoloured water visible along the foreshore caused by  the growth of phytoplankton   in sunny weather

But scientists at the Sir Alister Hardy Foundation for Ocean Science (SAHFOS) have analysed the bloom and found it is not pollution – it's plankton.

"Local residents may have noticed a brown scum that has enveloped the Plymouth shoreline in the past couple of days, and while it may not look very nice it is harmless and natural," said Gemma Brice, a plankton analyst at the SAHFOS.

"The scum has been caused by microscopic, phytoplankton algae which has been in its spring bloom."

Phytoplankton are essentially the plants of the sea – they produce over 50 per cent of the world's oxygen and are very important for life on earth.

Given the right conditions the phytoplankton will grow to large numbers (known as a bloom), just like plants on land.

"The hot and sunny weather we have had the past few weeks in combination with nutrients in the water has given rise to a bloom," added Gemma.

Gemma said while the bloom is not toxic, it would not be very pleasant to swim in.

Bacteria will degrade down the bloom which gives off the unpleasant smell.

    “@nevman
    Interesting response thank you; it gives an equally interesting insight possibly into your views
    When does civilised debate end and bullying start? some would say watch Flashman in HoC Question Time what do think?
    I fear you might have the wrong end of the stick over your phrase "blinkered parochialism"
    I thought it was an excellent tag for the ill-informed who seldom strayed out of their back yards and whose postings might well attract, probing, criticism or just ridicule. As we both keep reminding each other it's a free country.
    On bullying being an early bird I suppose I do sometimes set the agenda with my rosy tinted view of the world which does itself attract some bullying but that's free speech”

    “"Plankton just live off the existing nutrients in the sea (salt, minerals, nutrients from dead animals and plants, etc) and the sun is their energy source, hence why they probably came towards Plymouth on the sunny days."
    So do plankton just ignore additional nutrients from other sources? How exactly do plankton "come towards Plymouth on the sunny days"?
    The effect of excess nutrients on phytoplankton is well known, although obviously not to you.”

    “Yes, newplymouth, that's what I posted elsewhere, although I don't see how it's relevant to this thread. If you're that offended by me using the term 'blinkered parochialism', perhaps you can suggest a less contentious phrase to describe glossing over any shortcomings of a person's home town?

    Your "attempt at poking fun at the half glass empty brigade" didn't particularly upset me, apart from the fact that you say the same thing all over this website (sometimes even before anyone else has commented). Under the circumstances, that starts to look a bit like bullying.

    Express your views, by all means, but please don't belittle others for exercising the same right before they even post.”

    “@nevman
    I regret if my attempt at poking a bit of fun at the half glass empty people upset you!
    But as the author of 1984 said "The Freedom of Speech is the Freedom to upset others!"
    I most certainly support Free Speech and don't want to stiffle it!
    But when I find things like "blinkered parochialism" and other pointless negative comments I do like to challenge them. Whingeing too is often not very civil either!
    I do feel Plymouth does run itself down uneceassarily in comparison with others e.g Exeter and was it the same Nevman who posted the following elsewhere on this site?
    " based my comment on the fact that, having worked in both, I've encountered blinkered parochialism far more commonly in Plymouth than in Exeter.

    Something else you tend to find more in Exeter, I've found, is open-mindedness and civility. Perhaps we could learn a thing or two from our more prosperous neighbour"”

    “Oh, give it a rest, newplymouth. Other people are as just entitled to their opinions as you are. You contribute nothing to the debate which is a healthy and essential part of any community; all you want to do is stifle it. If you think that forced positivity leads to happy, thriving communities, take a look at North Korea!”

    “@Jannercide. Where does it say 'excess nutrients'?! Plankton just live off the existing nutrients in the sea (salt, minerals, nutrients from dead animals and plants, etc) and the sun is their energy source, hence why they probably came towards Plymouth on the sunny days.
    Stop being a pessamist.”
