Iverson develops algorithm for satellite data
by Laura Young
In 1992, when NASA issued a call for research using the Sea-viewing
Wide-field-of-view Sensor (SeaWiFS), Dr. Richard Iverson had a winning proposal.
He was selected as a SeaWiFS Science Team member for NASA's Mission to Planet
Earth, with four years of funding.

Cut in Apalachicola Bay
He was interested in determining how to use satellite ocean-color data to
calculate phytoplankton growth in different regions of the ocean. Over the
past three years, he has developed empirical equations to apply to data
from satellite images. The starting point was remotely-sensed data from
the Coastal Zone Color Scanner (CZCS), which orbited the Earth aboard the
Nimbus-7 Satellite.
Eyes in the sky
Satellites have dramatically extended our ability to observe the Earth's
oceans. Ship-based research allows scientists to study relatively small
portions of the global ocean at a time. Satellites circling the Earth can
survey the entire ocean in a day! They can measure sea-surface temperature,
wave heights, wave directions-and color. When astronauts look at the ocean
from space, they see different shades of blue. Orbiting satellites can carry
instruments that are more sensitive than the human eye, such as the CZCS
and SeaWiFS sensors, to measure a dazzling array of ocean colors.
CZCS color data has been interpreted to reveal the presence and concentration
of phytoplankton in the ocean. Information about these organisms, which
form the foundation of the food chain, can be useful in determining the
health and chemistry of the entire ocean.
Iverson proposed to go one step further-to use the color data to calculate
where phytoplankton were most productive.
When phytoplankton photosynthesis produces biomass, the process changes
the color of the ocean, even to the naked eye. Very productive water with
a high concentration of plankton appears blue-green. Unproductive water
appears a deep blue-black. From space, a satellite-mounted spectrometer
precisely measures the amounts of reflected light of different wavelengths,
which we see as colors.
Iverson and his colleague at NASA's Goddard Space Flight Center, Wayne Esaiahs,
discovered a mathematical algorithm that correlates chlorophyll concentrations,
as determined from satellite ocean-color data, with different levels of
phytoplankton productivity.
Their productivity calculations also reveal the amount of carbon dioxide
that phytoplankton are removing from sea water to build cells as they grow,
and the amount of organic carbon in dead phytoplankton that drop to the
ocean floor in fecal pellets.
In search of the missing sink
When SeaWiFS is launched from a Pegasus rocket, hopefully next year, it
will obtain measurements more frequently than its predecessor, CZCS. Iverson
then will apply his algorithms to a time-series of new ocean-color data
to determine the importance of phytoplankton's use of carbon in the carbon
cycle of the entire planet.
In recent years, scientists have become increasingly interested in determining
all the components of the global carbon cycle. Since the industrial revolution,
concentrations of carbon dioxide in the atmosphere have increased significantly.
The accumulation of carbon dioxide in both the atmosphere and the ocean
matches the estimated emissions until about 1920. After this time there
is an increasing gap between the two, suggesting that either the emission
estimates are much too high or there is a 'sink' not accounted for in the
balance.
"We know how much carbon from wood and coal combustion enters the atmosphere.
We can account for the carbon exchanged between the ocean inorganic pool
and the atmosphere," says Iverson. "We can estimate the carbon
going from the atmosphere to plants and soil on land."
And yet, not all the carbon up-take is accounted for. Iverson and Esaiahs
will use their algorithm to calculate the contribution of the ocean biological
process to the global carbon cycle, which may reveal the location of the
missing sink.
Tackling difficult science
How does his SeaWiFS work compare with his work on the important and politically
hot issue of the Apalachicola River water-diversion? One might expect that
doing science in a politically tense climate would be especially difficult,
but Iverson denies it.
"That's not difficult. It's straight data collection and analysis.
We found what we expected to find. If you reduce the amount of water coming
into the Apalachicola Bay, you're going to lower the amount of nutrients,
and that is the basis of productivity for the primary food chain.
"The difficulty with that issue lies at the political level. We only
provide facts that will be used by decision makers. In contrast, difficult
scientific problems, like creating new models and algorithms, involve working
past what is known."
Iverson first became interested in oceanography after taking limnology courses
at the Iowa Lakeside Laboratory at Lake Okaboji during his junior year at
Iowa State University. He obtained an undergraduate research participant
scholarship to work in aquatic ecology at Oak Ridge National Laboratory
before his senior year and was accepted at Oregon State University upon
graduation. He received his Ph.D. there in 1972.
Remarkably, Iverson has been working in the same room for the twenty-four
years since he earned his Ph.D. He joined the faculty at FSU in 1972, was
promoted to Associate Professor in 1977 and to Professor of Oceanography
in 1983.
"Although it looks like I have the same job," he says, "I
don't. The projects change, and new students come and graduate. It's a continually
refreshing profession."

Student spotlight
Fisher award goes to Cherrier
Jennifer Cherrier is the 1996 winner of the 18th Annual Graduate
Student James R. Fisher Award! At the seminar competition for the four finalists,
Jennifer presented her paper "Utilization and turnover of labile dissolved
organic matter by bacterial heterotrophs in eastern North Pacific surface
waters." Jennifer receives $300 and membership in the FSU Chapter of
the Society of Sigma Xi.
The James R. Fisher Award Competition is held yearly at FSU and is designed
to encourage the publication of original investigations by graduate students
in anthropology, biological sciences, computer science, earth sciences (geology,
meteorology, oceanography), engineering, mathematics, nutritional sciences,
philosophy of science, physical sciences, psychology, and statistics.
This year 24 graduate students submitted papers for the competition. Jennifer's
winning paper is soon to be published in Marine Ecology Progress Series.
Last year she also published an article: Cherrier, J., W. C. Burnett, and
P. A. LaRock (1995) "Uptake of polonium and sulfur by bacteria,"
Geomicrobiology Journal, 13: 103­p;115. Jennifer expects to receive her
Ph.D. in Biological Oceanography this summer.

Lia Stalder won this year's Student Travel Award. She received
$100 from the Thalassic Society, and the department paid for her ticket
to the AGU/ASLO Ocean Sciences Meeting in San Diego, where she presented
the poster "Biological responses to hypoxia and anoxia in the marine
environment: survival and behavioral avoidance patterns of three species
of calanoid copepods."
The Department of Oceanography recognized the following Outstanding
Students for 1996: Jennifer Cherrier, Bin Li, Rodney Powell,
and Jaye Young. Each student received $50 and an invitation
to membership in the FSU Chapter of the Society of Sigma Xi.
Serving as judges in the 1996 Capital Regional Science and Engineering
Fair were Ph.D. candidates Glynnis Bugna, Jennifer Cherrier,
and Stephanie Smith. Students in the fair, as well as members
of the community and parents who attended the fair, were impressed by those
who took time to help potential young scientists learn to carry out and
present experiments and projects.

On staff

Harkema gets results with patience, physics, and a well-used PC
by Laura Young
Take millions of incomprehensible blips recorded on cassette tapes
undersea, put them into the hands of Reinard Harkema, and what do you get?
Meaningful graphics whose swirls, lines, bars, and points have provided
the first step for researchers' interpretation of data for over 16 years.
According to Reinard, the proverb "a picture is worth a thousand words"
is especially true in the field of physical oceanography. He uses FORTRAN
programming, statistics, and a lot of patience to transform those blips
from the department's current meters.
"I feel very fortunate," says Reinard, "that the current-meter
staff put out a lot of good data. A large percentage of my time is spent
creating graphics from that data. People see me walking around with an oceanography
t-shirt on, and they ask me, 'Oh, do you dive?' 'No,' I say, 'I sit behind
a computer all day.'"
Dr. Georges Weatherly, director of the Current-Meter Facility, appreciates
Reinard's ability to consistently produce the required data analysis, and
he admires his "willingness to learn new data-analysis techniques,
even if this means taking a graduate-level course." He says that Reinard
is willing to tackle rather unusual data sets and has developed a valuable
instinct for identifying suspicious data values.
Harkema
"I was not trained in oceanography in any way," says Reinard,
"and I think Georges likes it that way because I don't have any preconceived
notions. I analyze the data, but I let someone else interpret it. That way
I always have an open mind."
Though not an oceanographer, Reinard came to the department with a solid
background in physics. After receiving his undergraduate degree in physics
at UNC-Chapel Hill, he completed a Master's degree and additional graduate
coursework in physics at FSU. He was teaching physics part-time at Tallahassee
Community College while working part-time for Dr. Weatherly, beginning in
1977. In 1980, Reinard took a full-time position with the department and
currently holds the title Computer Research Specialist, an administrative/professional-level
position.
Reinard recalls that when he first started working here, he did nearly all
his computer work using a mainframe, but now he can do everything from programming
to creating graphics to publishing the final data reports using a PC.
"I have more power sitting on my desktop now than I did back when I
used a mainframe," he says. "The environment makes it easier,
and the output looks a lot better than it used to, but basically, the mathematics
doesn't change."
In addition to his work in programming and graphics, Reinard says he is
the unofficial librarian for department copies of PC Magazine, and he serves
as the "archivist of all the [current-meter] data we've accumulated."
Dr. Weatherly notes that Reinard also has "a knack for resurrecting
ancient, but needed data-analysis programs."
Reinard and his wife Cheri married in 1981. They are active in the Church
of the Holy Spirit Episcopal and enjoy gardening and tennis. His most daunting
off-the-job project at the moment is getting their mountain retreat home
built in north Georgia. He says the view is spectacular, although he's not
sure how many basements they're going to have to add (two and counting)
down the steep slope before they'll be able to enjoy the sights from the
deck. Reinard seems to be as patient about the building of the mountain
home as he is about computer programming.
"If you try to push too fast," he says, "you'll pay for it
later."

In the field
Fire and ice: measuring methane in extremes
(left) Dr. Jeffrey Chanton spent five days during early March
in Alberta, Canada, in ­p;16°C weather to measure methane and carbon
dioxide fluxes in winter. Sampling equipment had to be tranported via snowmobile
and sled. Chanton collected smoky air during the controlled burn of a longleaf
pine forest (right) in February at the Jones Research Center in Newton,
Georgia. His analysis of the methane in these emissions is part of a program
to develop "chemical fingerprints" for particular sources of anthropogenic
methane emissions (such as coal mining, landfills, biomass burning, and
wastewater treatment). The results should provide a basis for planning a
national strategy for mitigation of greenhouse gas sources.

Learning the ropes
Students taking the course Geological Oceanography/Marine Geology boarded
the Suncoaster for a training cruise in the Gulf of Mexico off Carabelle
in April. Master's candidate Roger Wong (center) and two undergraduate
students prepare a water sampler.

And more ice...
FSU crew members were met with ice-covered equipment (above) when they boarded
the Oceanus at Woods Hole this February to deploy current-meter moorings
off Cape Hatteras as part of Dr. Georges Weatherly's Department of Energy
project.

- Abstract: Separation of U, Th, and Pa from environmental samples
(shells, minerals, etc.) is often required by geochemists for geochronological
and other applications. This work describes an efficient and relatively
rapid method for separation of these elements from marine phosphate minerals
and sediments. The main separation is accomplished via an extraction chromatographic
column with a final cleanup using standard ion exchange resin. There is
thus no need to employ waste-generating solvent extractions which are commonly
used for Pa separations. Because of the low natural abundance of 231Pa,
we conducted several tests to optimize its recovery. We also took steps
to ensure minimum contamination of the Pa source by U or Th nuclides which
could cause significant spectral interferences. Samples analyzed using this
method show typical Pa yields of about 90% and U/Th contamination of less
than 0.02% of the combined U/Th activity.

Pacific trade winds. Journal of Climate, May 1996, 1020­p;1028.
- Abstract: Eastward wind stress, averaged along the equator
from one side of the Pacific to the other, is the key meteorological quantity
for estimating long-term El Niño behavior in the eastern Pacific.
However, the long-term behavior of this meteorological variable is difficult
to determine directly both because too few data have been taken in the past
and because these false trends have been introduced by historical changes
in the way winds have been measured. For example, the eastern equatorial
Pacific wind record suggests that the equatorial trade winds have increased
substantially in strength over the last 20 years, and yet the sea-surface
temperature measurements in the eastern equatorial Pacific suggest that
the winds have actually weakened considerably. This work shows that the
equatorially averaged wind stress can be estimated from the difference in
surface atmospheric pressure at each end of the equatorial Pacific. Only
two atmospheric pressure measurements are thus needed in comparatively data-rich
regions near the coasts. Further, since atmospheric pressure measurements
have always been made in essentially the same way, false data trends are
avoided. These results confirm that the equatorial trade winds have weakened
rather than strengthened since the early 1970s. They also show that there
have been decadal changes in these winds since the 1920s. A proxy record
of eastern equatorial Pacific sea-surface temperature from Galapagos coral
suggests that such long-term weakening and strengthening of the Pacific
equatorial trades has occurred before major anthropogenic greenhouse gas
release and at least back to 1600 a.d.

The IOC baseline survey for trace contaminants in the Atlantic Ocean. EOS,
Vol. 77, No. 2, 9­p;13.
- Abstract: Scientists from five nations measured the concentrations
and distributions of more than 18 trace metals in both deep and surface
waters of the Atlantic Ocean during two international sampling efforts.
The measurements are valuable for monitoring elemental concentrations and
also have the power to reveal biogeochemical processes that affect trace
metals. This information is critically important for predicting the fate
of any potential contaminant in the marine environment. Preliminary results
from the two surveys show that the major water masses in the Atlantic have
characteristic trace metal signatures and that the simultaneous use of multiple
tracers to unravel geochemical questions is quite promising. This baseline
already has been used to show a decrease in anthropogenic lead concentrations,
presumably due to the removal of lead additives in gasoline. Surprisingly,
overall there were minimal anthropogenic effects detected by the two studies.
The first survey, conducted in the eastern Atlantic Ocean in 1990, showed
that atmospheric deposition greatly affects the biogeochemical cycling of
several trace metals (e.g., aluminum, iron, mercury, and antimony), and
that physical forcing (deep-water circulation, upwelling) strongly influences
the concentrations and distributions of trace metals. In the case of aluminum,
the data clearly show that waters in the Intertropical Convergence Zone
receive this metal when rainfall transfers aerosols from the atmosphere
to the ocean. The second cruise, in 1993, expanded the trace metal list
and was the first basin-wide survey ever to apply the baseline approach
to both inorganic and organic compounds. Data from the high-latitude North
Atlantic confirms that the water in this region is relatively young, which
results in little in situ modification of the original surface-water concentrations
of trace metals.

View from the bridge
Once again, it has been an interesting six months. Melvin Stern was designated
a Distinguished Research Professor, one of the highest honors in the university.
Graduate student Jennifer Cherrier won the student-paper competition sponsored
by the FSU Chapter of the Society of the Sigma Xi.
This spring, the biological oceanographers began a fund-raising effort.
When Winston Menzel died, a fund was established in his memory to provide
small travel and research grants to students in biological oceanography.
It benefited from gifts at the time of his death and the revenues from his
last book. The fund balance stuck about $1,200 short of the $10,000 required
for an interest-earning account. An appeal to Winston's friends and students
has resulted in a welcome response. We are nearly there; the fund needs
only about $100 more. To those of you who have already given, thanks very
much.
On another front, over the years, storage has been a big problem for the
department. We are a largely sea-going group, and some impressive piles
of oceanographic equipment are stuffed into every cranny of the building.
When Georges Weatherly received a grant that involved doubling the amount
of equipment in the Current-Meter Facility, we knew that the problem had
become serious. After about a year of inquiry and false starts, Georges
found that the department could build a warehouse at the FSU Farm of the
size we needed (4,000 sq. ft.) if we could just raise $155,000. Georges
put up $10,000. The department took a careful look at its budget and pledged
one third of the remaining amount. The College of Arts and Sciences and
the Division of Research each matched the department's contribution, so
we have the money! Plans are being drawn up by the Warehouse Building Committee.
In about 10 months, we will finally solve a storage problem that has been
with us for a very long time.
