An examination of Earth tremors in Nigeria shows activity mostly along northwest-southeast lines. This is contrary to earlier theories that the tremors occurred in the inland extension of the northeast-southwest oceanic faults.
In his last essay of a three-part series about the role of the Internet in ÛÏopening upÛ the geosciences, Lance Mckee examines the opportunities for geoscience stakeholders to forge the evolution of science through Internet-based geoprocessing standards and information technology.
The recent oil spill in the Gulf of Mexico, hurricane and tsunami disasters and ocean ‘health’ issues including ocean acidification highlight the importance of ocean observing systems. The authors provide overview current European (EuroSITES) and international (OceanSITES) initiatives and the growing need for high quality, high resolution ocean datasets to feed models and produce products and services to society.
A month after South Africa succesfully launched it’s second Earth observation satellite, Sumbandila, Earthzine contributor Peter Fairley talks with Dr. Philemon Mjwara, Director General of South Africa’s Department of Science and Technology, about the launch, the benefits South Africa expects to reap from the satellite, and what’s in store for the future of developing countries’ involvement in Earth observation and sustainability.
The “reality TV” craze that is sweeping a significant portion of the worldwide television-watching public has nothing on the worldwide “confluence hunting” craze that is sweeping a significant portion of adventurous geographers! Read Joseph Kerski’s reflections here.
Janet Rochester is a senior member of the IEEE leadership and president of the Society on Social Implications of Technology. In this interview she shines a spotlight on the range of SSIT members’ interests, and on her own intellectual considerations and concerns.
Under warm, sunny skies along Monterey Bay in California last May, marine scientists and engineers met with leading legislators and policy makers to confront some cold, hard, disturbing facts: Greenhouse gas emissions and other human-induced impacts are threatening the health of marine life, and coordinated action between policy makers and scientists is needed now to address this enormous problem.
The Canadian Space Agency (CSA) understands the tremendous role and value that space-based Earth Observation (EO) systems and information have regarding disaster management, mitigation, response and its environmental and socio-economic impacts and benefits. Security, which includes disaster and geohazard management, is one of the three pillars of the CSA EO strategy.
Accurate prediction of sea level is arguably one of the most important societal goals facing the research community. Combining cutting-edge technologies with sustained observations to understand processes and improve numerical models will be required to address the issue of future ice-sheet changes and impacts on global sea level.
Two scientists participating in a live International Polar Day event March 12 provided their insights into what the future may hold and what decision-makers should do to address the issue.
