We wanted to update you on what ROFFS
has been doing regarding the Deepwater Horizon
oil spill. On a daily basis we have continued
mapping the surface currents in the Gulf of
Mexico that we believe have been affecting the
distribution of the water that either came into
contact with the surface oil and most likely came
in contact with the surface oil water and
dispersant mixture. Since the amount of surface
oil in the Gulf of Mexico is very small compared
with what it had been we have added a new
component to our work that relates to the
subsurface plume cloud of oil, dispersants and
water. We will not go into detail about the
molecular nature of this cloud plume since we do
not know its true composition, but the reports
that we heard from the NOAA - Unified Command
indicate that the concentrations of oil -
dispersants are on the order of parts per million
- parts per billion. We have been focusing our
efforts into understanding the movements of the
ameba like subsurface plume cloud. To this end we
have been monitoring some of the deeper water
current measurements in the area where it has
been suggested that this plume cloud exists. We
have never seen a map of this plume cloud, but it
had been described to us a few weeks ago. We have
requested maps of the plume cloud from many
sources, but we continue to have nothing.
While we realize that the surface
currents and the subsurface currents below the
thermocline are often de-coupled (i.e., not
moving in the same direction and not affected by
the same forces), we are studying the
relationship between the surface and subsurface
currents. We hope that we can give guidance to
the motion of the subsurface cloud plume.
Knowing the spatial temporal history of the
surface and subsurface oil - dispersant mixture
is critical in understanding the effects of the
oil on the ecosystem.
We are still concerned about the long
term effects of the oil - dispersant mixture on
the ecosystem. We are concerned about the effects
of the oil that remains on the bottom of the
ocean and in the sand along the beaches. All of
the oil is not gone. We continue to hear about
oil (red globules) coming to the surface along
the Louisiana coast and rumors of oil elsewhere.
We read about oil in the bottom sediments. Not
all of this information is getting into the
newspapers and TV reports. More information is
needed to be released so that independent
scientists can evaluate the effects of the oil.
We understand the issues related to quality
control, but more information needs to be
available in easy to use formats.
Enclosed are our last two analyses for your reading pleasure.
Safe and Successful Fishing,
Mitchell A. Roffer, Ph.D.
