 A question, I have seen the sea take on a few colours blue, bluey green, etc. and I know the sea floor, sky conditions can make a difference.  There is a place I have visited quite a lot over the last ten years or so where the sea has always been blue.  It's about 340ft deep, bottom is largely sand.  It has now taken on a green colour, but a shade of green I have not seen before it looks like an inland lake sort of colour.  I would have thought it is too far from shore (approx 120miles) to be silt washed out from heavy rains.  Anybody any ideas

They do get algae and it can come in some strange colours.

Re: Colour of the Sea

 Thanks for the replies, could be the silt then that has amazed me that it will travel so far.  Greg somebody else has suggested to me that it might be algae.  Thanks again, I'll see what it's like the next time I am that way

cheers

Re: Colour of the Sea

Algea is a micro organism plant life and given the right conditions reproduces rapidly and can spread to many square miles,these can be easily seen by satellite imagery, any large blooms are generally investigated for any risk to human or fish life.

Thanks deerstalker, I am not aware of any such investigations but that's not to say there aren't any.  The fish still seem to be around so perhaps it's not affecting them.  Those images you got can you get them updated for anywhere or do they only show a place where there is something of interest.  I had a bit of a look but could only seem to get images of america and it's coastlines, I couldn't even see the one's you posted   cheers

Re: Colour of the Sea

 Hi Codfathers, Like I say it makes the sea look like an inland lake in colour, as if was mud in suspension, it is not something on the surface so perhaps it's not algae and I have seen the algae you are talking about and it's definitely not the same as that. I will let you know what it's like next time I go there cheers.
