    This progress report summarises work on NSHEB Mark 10 fish counters which are installed at Woodmill on the River Itchen and Nurseling Mill and Connegar Bridge on the River Test. Counters are evaluated and salmon behaviour regarding the counters examined. The report includes a a list of equipment needed for the efficient running of the project in the future

    The ecology of chalk-stream invertebrates studied in a recirculating stream

    Get PDF
    To study and qualify the factors influencing interactions between various trophic levels in natural hard-water streams, a recirculating artificial stream channel was constructed. This structure has enabled patterns of population change of stream fauna to be observed under partially controlled physical and chemical conditions. Initial colonization of the substratum by invertebrates and subsequent succession was studied along with depth distribution and growth and production studies of invertebrates

    International NGOs in New York City: A Comparative Study

    Get PDF
    New York City is a global city, not just for its place in the global market, or for its role as an innovator of policy. This report indicates it should also be known for its significant contributions in the field of international nongovernmental organizations (INGOs). Using data collected from IRS Form 990 tax filings, this report creates the first comprehensive assessment of the INGO sector in NYC and demonstrates that New York City's INGO sector is not only a leader of the nationwide INGO sector, but it also reflects the city's unique history and diverse population

    An Overview of the Micro Pulse Lidar Network (MPLNET)

    Get PDF
    The NASA Micro Pulse Lidar Network (MPLNET) is a federated network of Micro Pulse Lidar (MPL) systems designed to measure aerosol and cloud vertical structure continuously, day and night, over long time periods required to contribute to climate change studies and provide ground validation for models and satellite sensors in the NASA Earth Observing System (FOS). At present, there are eighteen active sites worldwide, and several more in the planning stage. Numerous temporary sites are deployed in support of various field campaigns. Most MPLNET sites are co-located with sites in the NASA Aerosol Robotic Network (AERONET) to provide both column and vertically resolved aerosol and cloud data. MPLNET data and more information on the project are available at http://mpinet.gsfc.nasa.gov . Here we present a summary of the first ten years of MPLNET, along with an overview of our current status, specifically our version two data products and applications. Future network plans will be presented, with a focus on our activities in South East Asia
