True color: measures
the amount of dissolved organic matter and suspended particulate matter in
the water column. As the
concentration of dissolved organics such as tanins and lignins increase,
light absorption of ultraviolet and violet wavelengths increases
|
|
-TMP mean lower than maine
avg,and lower than other china region lakes -considered uncolored
|
|
-color readings
correspond to transparency
readings -could be due to an increase in development in watershed which
would decrease the amount of tanins and lignins from forest floors
|
|
Conductivity: measures
ability of a body of water to carry an electrical current
|
|
-strength of current
depends on the concentration and extent of dissociation of dissolved ions in
the water column
|
|
-closely linked to color
and transparency
|
|
-conductivity values
slightly higher than normal, but are still comparable to other Maine lakes
|
|
Physical measurements
show that TMP is comparable to other area lakes - DO and transparency
readings indicate a delining lake health
