Tues. Dec. 6, 1:20 p.m. EST (10:20 a.m. PST), MCC 2004
The direct transport of forest fire smoke into the stratosphere by pyro-cumulonimbus clouds provides a dramatic example of the rapid rise of dust and particles from the lower atmosphere. This presentation will discuss the role of these events in aerosols in the lower stratosphere and its effect on the circulation of the atmosphere as seen in computer model simulations.

This session discusses NASA’s SeaWIFS satellite observations, which show large unexplained phytoplankton blooms in the Pacific Ocean that can be as large as the state of California. The blooms develop in a part of the ocean with low nutrients that would seem incapable of supporting them. A second talk, “Western Pacific Modulation of Large Phytoplankton Blooms in the Central and Eastern Equatorial Pacific,” at 2:35 p.m. EST (11:35 a.m. PST) on Tuesday (Session OS22B-06), details a recently discovered pattern of large blooms following El Niños and examines a hypothesis for their existence more than 6,214 miles away.
Southern Ocean "Superbloom" of 2000
Tues., Dec. 6, 4:40 p.m. EST (1:40 p.m. PST), MCC 3012
This presentation offers a valuable glimpse into seasonal and inter-annual fluctuations in ocean carbon cycling in the Antarctic’s Southern Ocean, an area responsible for removal of a large fraction of atmospheric CO2. This study finds these high fluctuation rates have implications for the world’s marine ecosystems and the global carbon cycle.

Wed., Dec. 7, 12:40 p.m. EST (9:40 a.m. PST), MCC 2002
An August 2003 Canadian forest fire exploded into a pyro-cumulonimbus cloud, creating a distinct plume of smoke. This presenations focuses on the use of NASA satellites to study the life cycle of this plume, cloud-top changes, and the transport of smoke from the lower atmosphere through to the stratosphere.
Teleconnection Over the Atlantic: The Bodele Depression, A Single Dust Source is Responsible to Most of the Wellbeing of the Amazon Rainforest
Wed., Dec. 7, 4:40 p.m. EST (1:40 p.m. PST), MCC Level 2
Saharan dust, suggested to be the main mineral source that fertilizes the Amazon basin, is generally carried on the westward trade winds from Africa between November and March. Using a combination of data from three satellite instruments, this presentation will show that the emissions and transport of Saharan dust to the Amazon originate mostly from a small source northeast of Lake Chad.
Did Plio-Pleistocene Warm Events Cause Destabilization of Ice Sheets, or Vice-Versa?
Thurs., Dec. 8, 6:25 p.m. EST (3:25 p.m. PST), MCC 3006
Historically, short duration, apparently climate-changing events occurred during the Pliocene and early Pleistocene eras. Emerging evidence suggests that major changes also took place in the Greenland and West Antarctic ice sheets at the same time as these events. In this talk, NASA researchers explore physical processes and mechanisms at play. They also argue the sources for the global signals we interpret as "warm events," and how we can better understand what, if any, implications there may be for future behavior of the ice sheets.
A Landsat Record of North American Forest Disturbance
Fri., Dec. 8, 11 a.m. EST (8 a.m. PST), MCC Level 1
Analysis of Landsat satellite data has proven useful in diagnosing forest disturbance, growth and recovery. This presentation examines regions with high rates of biomass loss (disturbance) or gains (recovery) and finds a strong correlation between areas of harvesting and fire activity, such as the southeastern U.S., Maine and the Pacific Northwest.
Observed Trends of NDVI and Climate Over the Amazon Basin
Thurs., Dec. 8, 4:40 p.m. EST (1:40 p.m. PST), MCC Level 1
The carbon balance of Amazon rainforests plays a key role in the global carbon budget. NASA-funded researchers suggest a possible increasing trend in the growth rate of these forests. This presentation will discuss the probability that an increasing vegetation trend could be due to the rise in short-wave radiation that is enhancing growth in these light-limited ecosystems.
