SATELLITES SEE BIG CHANGES SINCE 1980s
IN KEY ELEMENT OF OCEAN'S FOOD CHAIN
NASA Press Release 02-153
Since the early 1980s, ocean phytoplankton
concentrations that drive the marine food chain have declined
substantially in many areas of open water in Northern oceans,
according to a comparison of two datasets taken from
satellites. At the same time, phytoplankton levels in open
water areas near the equator have increased significantly.
Since phytoplankton are especially concentrated in the North,
the study found an overall annual decrease in phytoplankton
globally.
The authors of the study, Watson Gregg, of NASA's Goddard
Space Flight Center, Greenbelt, Md., and Margarita Conkright,
a scientist at the National Oceanic and Atmospheric
Administration's (NOAA) National Oceanographic Data Center,
Silver Spring, Md., also discovered what appears to be an
association between more recent regional climate changes,
such as higher sea surface temperatures and reductions in
surface winds, and areas where phytoplankton levels have
dropped.
The researchers compared two sets of satellite data -- one
from 1979 to 1986 and the other from 1997 to 2000 -- that
measured global ocean chlorophyll, the green pigment in
plants that absorbs the Sun's rays for energy during
photosynthesis. The earlier dataset came from the Coastal
Zone Color Scanner (CZCS) aboard NASA's Nimbus-7 satellite,
while the latter dataset was from the Sea-Viewing Wide Field
of View Sensor (SeaWiFS) on the OrbView-2 satellite.
The researchers re-analyzed the CZCS data with the same
processing methods used for the SeaWiFS data, and then
blended both satellite measurements with surface observations
of chlorophyll from ocean buoys and research vessels over
corresponding time periods. By doing so, the researchers
reduced errors and made the two records compatible.
Results indicated that phytoplankton in the North Pacific
Ocean dropped by over 30 percent during summer from the mid-
80s to the present. Phytoplankton fell by 14 percent in the
North Atlantic Ocean over the same time period.
Also, summer plankton concentrations rose by over 50 percent
in both the Northern Indian and the Equatorial Atlantic
Oceans since the mid-80s. Large areas of the Indian Ocean
showed substantial increases during all four seasons.
"This is the first time that we are really talking about the
ocean chlorophyll and showing that the ocean's biology is
changing, possibly as a result of climate change," said
Conkright. The researchers add that it remains unclear
whether the changes are due to a longer-term climate change
or a shorter-term ocean cycle.
Phytoplankton thrive when sunlight is optimal and nutrients
from lower layers of the ocean get mixed up to the surface.
Higher sea surface temperatures can reduce the availability
of nutrients by creating a warmer surface layer of water. A
warmer ocean surface layer reduces mixing with cooler, deeper
nutrient-rich waters. Throughout the year, winds can stir up
surface waters, and create upwelling of nutrients from below,
which also add to blooms. A reduction in winds can also limit
the availability of nutrients.
For example, in the North Pacific, summer sea surface
temperatures were .4 degrees Celsius (.7 Fahrenheit) warmer
from the early 1980s to 2000, and average spring wind
stresses on the ocean decreased by about 8 percent, which may
have caused the declines in summer plankton levels in that
region.
Phytoplankton currently account for half the transfer of
carbon dioxide from the atmosphere back into the biosphere by
photosynthesis, a process in which plants absorb carbon
dioxide (CO2) from the air for growth. Since carbon dioxide
acts as a heat-trapping gas in the atmosphere, the role
phytoplankton play in removing carbon dioxide from the
atmosphere helps reduce the rate at which CO2 accumulates in
the atmosphere, and may help mitigate global warming.
The paper appears in the current issue of Geophysical
Research Letters. For more information, please see:

STUDY: IN GLOBAL WARMING FIGHT, TREES NOT ALWAYS BEST ANSWER
from The Associated Press
LOS ANGELES (AP) -- Scientists say they have overestimated the potential of
trees and shrubs to soak up carbon from the atmosphere. The
reassessment casts doubt on
whether planting trees is always a positive step in the fight against
global warming, as
President Bush and others have suggested. Details of the new study
appear in Thursday's issue of the journal Nature.
Duke University scientists say trees and shrubs growing in areas of
abundant rainfall are less effective storehouses for carbon than
native grasslands they have
steadily replaced across much of the western United States.
Vegetation stores carbon that otherwise might trap heat in the atmosphere,
driving up temperatures and leading to climate change.

UNEXPECTED FINDING: TRAILS OF JETS AFFECT CLIMATE
from Newsday
An unexpected experiment - the sudden three-day grounding of air traffic
after last
September's terrorist attacks - shows that high altitude jet contrails are
having an important impact on temperatures, scientists said yesterday.
Because thousands of commercial flights were canceled after the disaster,
the researchers said, a thin blanket of cirrus clouds that often
forms from water vapor exiting jet engines in high traffic corridors
was absent. The lack of clouds allowed daytime temperatures at ground
level to rise and nighttime temperatures to fall. The researchers
said the loss of cloud cover caused by the grounding of commercial
planes led to a 1.98-degree increase in the difference between the
highest day temperature and lowest night temperature over the United
States. Their report showing the human impact on temperature was
published in today's issue of Nature.

Second Announcement and call for abstracts
Abstract and early registration deadline:15 October 2002
This conference will focus on integrated studies of biogeochemistry
and ecosystem dynamics in the ocean in the context of the Earth System
and global change. It is designed to assist the development of a new
ten-year international SCOR/IGBP research project. Questions to seed
discussion include:
*How does global change, represented by changes in natural climatic
modalities and anthropogenic forcings, impact marine biogeochemical
cycles and ecosystem dynamics?
*How do these impacts alter the mechanistic relationship between
elemental cycling and ecosystem dynamics?
*What are the feedback mechanisms to the Earth System from these
changes?
In addition to plenary and poster presentations, there will be two full
days of working group discussions. Abstracts are invited for poster
presentations on themes such as: Trace elements in ecological and
biogeochemical processes; The mesopelagic layer; Integrating food-
web dynamics and biogeochemical cycles; Direct effects of
anthropogenic forcing on biogeochemical cycles and ecosystems;
Feedbacks to the Earth System; Biogeochemical hotspots, triggers and
non-linear responses.
