Sea Water Differences by Location
Country: United States
Date: August 2007
There is nothing separating the sea water from Florida and
New York. So, how is it that in Miami I can see the crystal clear
water and view my feet and in New York I cannot? Is there a natural
form of water purification? If so what is it?
Water clarity depends upon a large number of factors which include, but
are not limited to: wave action, water temperature and algal life,
seabed and onshore geology, pollution, nearness of sediment sources such
as rivers, whether the area is sinking or rising from the sea, sun
light, time of depth, water depth, presence of and direction of
currents, marine animals present, range of tides (or no tides).
Depending upon where you are in Florida and New York there is a major
difference in sea bed and onshore geology. Florida is lime and New York
is old glacial deposits. There are also far fewer sources of sediment,
ie. rivers and creeks, in Florida. As I remember it, waves are bigger
and stronger on Long Island's south shore than in much of Florida and
this keeps sediments stirred up.
By the way, if you think New York seawater is cloudy, visit the Texas
and Louisiana Gulf coasts. Long-shore currents and sediments from the
Mississippi and other rivers keeps these waters almost opaque near
