Pumped Storage: Simple Changes, Big Savings, Charles M. Burt Jan 2001

Pumped Storage: Simple Changes, Big Savings, Charles M. Burt

BioResource and Agricultural Engineering

Several California irrigation districts achieved savings on electrical energy charges by implementing various types of pumped storage systems. Pumped storage uses some type of reservoir to store pumped water at a higher elevation than the original water supply. During times of peak statewide electricity demand, pumping is reduced while water is withdrawn from the reservoir which acts as a buffer.

Evaluation Of Retrievable Drip Tape Irrigation Systems, Charles M. Burt, Jess T. Barreras Jan 2001

Evaluation Of Retrievable Drip Tape Irrigation Systems, Charles M. Burt, Jess T. Barreras

BioResource and Agricultural Engineering

California growers of lettuce, broccoli, celery, and cauliflower have long been leaders in drip tape applications. Starting in the early 1990s, large acreages of buried, subsurface drip irrigation (SDI) were installed with the intent of leaving the tape in the ground for up to 10 years (Burt and Styles, 1999). Tape burial depths were typically 20 - 25 cm below the soil surface. Although yields and irrigation efficiencies typically increased, there were numerous challenges with SDI. Since the tape was buried, such issues occurred as gopher damage, problems with root intrusion, soil back-siphonage when the system was shut off, damage …

Adaptive Sampling In The Coastal Ocean At The Long Ecosystem Observatory, Mark A. Moline, W. Paul Bissett, Scott Glenn, Dale Haidvogel, Oscar Schofield Jan 2001

Adaptive Sampling In The Coastal Ocean At The Long Ecosystem Observatory, Mark A. Moline, W. Paul Bissett, Scott Glenn, Dale Haidvogel, Oscar Schofield

Biological Sciences

A multi-platform inter-disciplinary observation network has been operating at the Rutgers University Long-term Ecosystem Observatory (LEO) since 1996, with real-time capabilities beginning in July 1999. The network integrates numerous remote (satellites and shore- based), stationary (surface and subsurface), moveable (ships and AUVs) observation systems. The observation network provides spatially extensive updates of the physics, optics, chemistry and biology on time scales of an hour or less which are communicated in real-time to shipboard scientists and AUV operators. This rapid environmental assessment capability is already changing current paradigms for ocean adaptive sampling strategies. For example, in the well-sampled ocean, where forecast …

Modeling Atmosphere-Ocean Interactions And Primary Productivity, Joe Grzymski, Mark A. Moline, Jay T. Cullen Jan 2001

Modeling Atmosphere-Ocean Interactions And Primary Productivity, Joe Grzymski, Mark A. Moline, Jay T. Cullen

Biological Sciences

The heat budget, and hence the climate of the Earth, is sensitive to changes in the atmospheric greenhouse gas composition. Next to water vapor, carbon dioxide (CO2) is the most important atmospheric greenhouse gas affecting the Earth's radiative balance. Greenhouse gases raise the mean temperature of the Earth by absorbing and trapping long-wave radiation from the planet surface that would otherwise be lost to space.

Changes In Phytoplankton Assemblages Along The Antarctic Peninsula And Potential Implications For The Antarctic Food Web, Mark A. Moline, Herve Claustre, Thomas K. Frazer, Joe Grzymski, Maria Vernet Jan 2001

Changes In Phytoplankton Assemblages Along The Antarctic Peninsula And Potential Implications For The Antarctic Food Web, Mark A. Moline, Herve Claustre, Thomas K. Frazer, Joe Grzymski, Maria Vernet

Biological Sciences

The majority of the yearly organic carbon production int he coastal regions of the Southern ocean occurs during summer blooms. Changes in the quantity and quality of the phytoplankton standing crop during this period will likely impact organisms that occupy higher trophic levels within the ecosystem. Here we report a recurrent shift in the dominant phytoplankton taxa during the austral summer in a coastal region along the Antarctic Peninsula. The pattern was observed each year between 1991 and 1996 despite radically different biomass concentrations and meteorological and hydrographic conditions. We show that a repeated dominance of cryptophytes (Cryptophyceae) during the …

Impact Of Dynamic Light And Nutrient Environments On Phytoplankton Communities In The Coastal Ocean, Mark A. Moline, Oscar Schofield, Joe Grzymski Jan 2001

Impact Of Dynamic Light And Nutrient Environments On Phytoplankton Communities In The Coastal Ocean, Mark A. Moline, Oscar Schofield, Joe Grzymski

Biological Sciences

Phytoplankton represent the base of the food web in marine ecosystems. Changes in the structure and composition of these phytoplankton communities will, therefore, have a direct effect on the amount of carbon available to higher trophic levels. In the absence of significant grazing, light and nutrients are the primary factors regulating phytoplankton photosynthesis and productivity in marine environments. As the requirements for light and nutrients differ between species, phytoplankton community structure is also sensitive to dynamic optical and chemical conditions in the water column.

A New Wildlife Sighting Reporting And Database System For Lassen Volcanic National Park, John D. Perrine, Jonathan F. Arnold Jan 2001

A New Wildlife Sighting Reporting And Database System For Lassen Volcanic National Park, John D. Perrine, Jonathan F. Arnold

Biological Sciences

Visitors and employees in national parks may observe species of interest to wildlife biologists and resource managers. These sightings are useful to researchers and managers only if the data can be efficiently acquired, stored and retrieved for analysis.· We identified several problems in the wildlife sightings reporting system at Lassen Volcanic National Park, including a confusing array of reporting forms; incomplete contact information for the reporter; insufficient reporting of the animal's description, behavior and location; and a cumbersome data entry and retrieval system. We developed a new system to correct these problems. A single reporting form corrects the aforementioned data …

Murgo Farms Inc.: Haccp, Iso 9000, And Iso 14000, David Sparling, Jonathon Lee, Wayne Howard

Agribusiness

Murgo Farms Inc., addresses the challenge of choosing between the Hazard Analysis Critical Control Point (HACCP), International Organization of Standardization (ISO) 9000, and ISO 14000 systems for a business with grain farming, elevator and spraying enterprises. Murgo has recently entered markets that are more quality oriented and wishes to expand its activities in those markets. The President wonders whether HACCP or ISO 9000 might help that expansion. However, the company is also faced with significant environmental risks due to its spraying and manure spreading activities and its proximity to a local municipal water source. There are good reasons for Murgo …

Above‐Threshold Ionization As A Probe Of Multielectron Physics, L. D. Van Woerkom, M. J. Nando, M. A. Walker, G. D. Gillen, H. G. Muller Jan 2001

Above‐Threshold Ionization As A Probe Of Multielectron Physics, L. D. Van Woerkom, M. J. Nando, M. A. Walker, G. D. Gillen, H. G. Muller

Physics

The study of above-threshold ionization (ATI) is now over 20 years old and much has been learned about the interaction of a single atomic electron with intense laser fields. The development of stable, high repetition rate ultrashort pulse laser systems has allowed experiments to probe intricate details of the ionization process using photoelectron and photoion spectroscopies. To date the overwhelming majority of data show that intense laser fields interact with only a single electron at a time to produce the well known features in electron kinetic energy spectra. We will present an overview of state-of-the-art experiments in ATI and show …
