    Notes: Abstract The time interval between successive bursts from SGR 1806-20 and the intensity of these bursts are both consistent with lognormal distributions. Monte Carlo simulations of lognormal burst models with a range of distribution parameters have been investigated. The main conclusions are that while most sources like SGR 1806-20 should be detected in a time interval of 25 years, sources with means about 100 times longer have a probability of about 5% of being detected in the same interval. A new breed of experiments that operate for long periods are required to search for sources with mean recurrence intervals much longer than SGR 1806-20.

    Notes: Abstract The Noel Kempff Climate Action Project in Bolivia, nowin its third year, is breaking ground to establishcredible and verifiable methods to quantify greenhousegas (GHG) benefits of land-use change and forestry (LUCF)projects. Developed under the United Nations FrameworkConvention Climate Change (FCCC) Activities ImplementedJointly pilot phase, the project conserves naturalforests that would otherwise have been subjected tocontinued logging and future agricultural conversion.Carbon (C) monitoring began with a C inventory of theproject area in 1997. The total amount of C in theproject area was 118 Tg (Tg = 1012g) ± 4%(95% confidence interval). Periodic monitoring ofrelevant C pools (occurring in 1999 and every 5 yrthereafter) occurs over the 30-year life of theproject to establish the difference between thewith-project and projected without-project scenarios. Permanent sample plots were established both insidethe project area to monitor changes in C pools overtime and in a proxy logging concession near theproject area to determine changes in C pools inforests that have been impacted by logging. Ground-based monitoring is complemented by datacollection on forest industry trends and land-usechange patterns. Remote sensing was used to developa vegetation stratification map of the area, and workis ongoing to investigate the potential application ofdual-camera aerial videography to improve theefficiency of monitoring over time.
