ABSTRACT
Light passage through water
is affected by suspended materials in water. Secchi depths are simply used for the
measurement of water clarity, in other words turbidity. The purpose of the present
study was to determine whether the turbidity trend in the Menai Strait, Wales, UK
is a local or worldwide pattern by comparing Secchi depths in the Strait with the
ones from Skomer MNR, Wales, UK and from L’Estartit, Spain. Therefore, the hypothesis
that long term changes in Secchi depth are driven by long term changes in wind speed
was tested using correlation and regression analyses. For the Menai Strait, a computer
model based on the mathematical relation between turbulent kinetic energy and Secchi
depth was constructed. There were significantly negative correlation between monthly
Secchi depth—wind speed pairs of Menai Strait—Anglesey and Skomer MNR—Cardiff but
no correlation between annual pairs of Menai Strait—Anglesey and L’Estartit—Barcelona.
As a result, it was proposed that high turbidity in the Menai Strait could not be
explained by only wind speed, moderate turbidity in Skomer MNR could be driven by
moderate wind and clear water of L’Estartit could not be explained by wind speed.
It was concluded that wind alone could not cause turbidity without suspended particles
in water but if there was a source of suspended particles, the wind would make the
water more turbid.
