Controlling the Spread of Asian Carp.
02/04/2010
-- Hydrologists from the USGS Ohio and Illinois Water Science Centers recently aided a multiagency effort to help protect Lake Michigan and the other Great Lakes from Asian carp. The hydrologists made streamflow and velocity measurements in the Chicago Sanitary and Ship Canal, and they injected and tracked Rhodamine dye (a nontoxic fluorescing dye) prior to application of Rotenone, a fish toxicant. The Rotenone application was designed to prevent Asian carp from advancing through a fish barrier on the canal reach while the barrier was shut down for maintenance, and the dye-study information was used to help plan the Rotenone application. USGS hydrologists injected Rhodamine dye again during the Rotenone application to help track the toxicant so that workers would know when and for how long to administer a detoxifying agent at the downstream end of the reach to prevent fish kills farther downstream.

Toxic Algae Meeting Convened.
11/18/2009
-- Cyanobacteria (blue-green algae) can produce toxins harmful to humans and deadly
to fish and pets. In recent years Microcystis, a common type of toxic
algae, has reemerged in parts of Lake Erie and some inland lakes of Ohio. The
USGS Ohio Water Science Center recently hosted a meeting on toxic algal issues
with representatives from Federal, state, and local agencies and organizations.
Presentation topics ranged from toxin genetics to a landscape analysis and
included a talk on the Ohio EPA’s
Ohio Harmful Algal Bloom (HAB) Initiative and the
state of the science by toxic algae expert Jennifer Graham of the USGS
Kansas Water Science Center.
Celebrate Earth Science Week – October 11-17, 2009.
10/9/2009
-- "Understanding Climate" is the theme for this year's
Earth Science Week. The
USGS is a major contributor to this annual international event sponsored by
the American Geological Institute. Earth Science Week promotes responsible
stewardship of the Earth and encourages children and adults alike to explore the
earth sciences. Scientists from the Ohio Water Science Center are taking
representatives from several Ohio agencies to a streamgage to demonstrate the
operation of gages and describe the variety of ways streamgage data are used,
including the role streamgages play in understanding climate. There are many
Earth Science Week
events in Ohio
and throughout the world open to the public. Earth science is all around us!
