KEY WEST,
Fla. -- Scientists plan to test samples taken from a
mysterious patch of discolored water off the Marquesas Keys that
could be a resurgence of "black water" that affected southwest
Florida into last year. Fishermen described the patch as milky,
mustard or black, in an area between the Marquesas and the Dry
Tortugas.
Most fish seem to avoid the area, and ones that are seen
in the patch aren't biting or putting up much of a fight when
hooked, fishermen said. Researchers are monitoring the water
using satellites and have ordered testing of the water, slated to
begin next week. Fishermen have been given test kits to gather
samples and help with the study. The plankton and algal blooms in
the water appear five times less concentrated as the "black water"
that first appeared in late 2001 off southwest Florida, said
Chuanmin Hu, an oceanographer with the University of South Florida's
College of Marine Science. The black water tested in 2002 showed
a high abundance of nontoxic microscopic plants and was blamed on a
large, nutrient-rich patch of runoff combined with a severe outbreak
of red tide. "It's pretty much similar, but to a less
extent. It's not as dark as the 2002 black water," said Hu, who has
been tracking red tide and other algal blooms in the area. Some
sections of the mysterious water span nearly 20 miles, Hu
said. He traces the
mysterious water to Charlotte Harbor, 175 miles north of
theKeys. The Peace River dumps into the harbor there, after
flowing through several farming communities that have nutrient rich
runoff water spilling into the waterway. Satellite images show
several large algal blooms spanning from Charlotte Harbor to the Dry
Tortugas, Hu said.
