New software methods in radar ornithology using WSR-88D weather data and potential application to monitoring effects of climate change on bird migration New software methods in radar ornithology using WSR-88D weather data and potential application to monitoring effects of climate change on bird migration
Radar ornithology has provided tools for studying the movement of birds, especially related to migration. Researchers have presented qualitative evidence suggesting that birds, or at least migration events, can be identified using large broad scale radars such as the WSR-88D used in the NEXRAD weather surveillance system. This is potentially a boon for ornithologists because such data...

Ocean and coastal data management Ocean and coastal data management
We introduce data management concepts, including what we mean by "data" and its "management," sources of data, interoperability, and data geometry. We then discuss various components of a data management system. Finally, we summarize some existing ocean and coastal data management efforts. We make specific recommendations throughout the paper. We are generally optimistic that ocean and...

Overview of selected surrogate technologies for high-temporal resolution suspended-sediment monitoring Overview of selected surrogate technologies for high-temporal resolution suspended-sediment monitoring
Traditional methods for characterizing selected properties of suspended sediments in rivers are being augmented and in some cases replaced by cost-effective surrogate instruments and methods that produce a temporally dense time series of quantifiably accurate data for use primarily in sediment-flux computations. Turbidity is the most common such surrogate technology, and the first to be

Seasonal and decadal-scale channel evolution on the dammed Elwha River, Washington Seasonal and decadal-scale channel evolution on the dammed Elwha River, Washington
More than 75,000 dams exist in the continental United States to provide water storage, flood control, and hydropower generation (Graf, 1999). Many of these were built during the early twentieth century and are due for relicensing consideration now and in the near future. The cost of repairing aging dams, together with growing understanding of the ecologic effects of river regulation...

Sediment transport on Cape Sable, Everglades National Park, Florida Sediment transport on Cape Sable, Everglades National Park, Florida
The Cape Sable peninsula is located on the southwestern tip of the Florida peninsula within Everglades National Park (ENP). Lake Ingraham, the largest lake within Cape Sable, is now connected to the Gulf of Mexico and western Florida Bay by canals built in the early 1920's. Some of these canals breached a natural marl ridge located to the north of Lake Ingraham. These connections altered...

Serving ocean model data on the cloud Serving ocean model data on the cloud
The NOAA-led Integrated Ocean Observing System (IOOS) and the NSF-funded Ocean Observatories Initiative Cyberinfrastructure Project (OOI-CI) are collaborating on a prototype data delivery system for numerical model output and other gridded data using cloud computing. The strategy is to take an existing distributed system for delivering gridded data and redeploy on the cloud, making...

Standard-target calibration of an acoustic backscatter system Standard-target calibration of an acoustic backscatter system
The standard-target method used to calibrate scientific echo sounders and other scientific sonars by a single, solid elastic sphere is being adapted to acoustic backscatter (ABS) systems. Its first application, to the AQUAscat 1000, is described. The on-axis sensitivity and directional properties of transducer beams at three operating frequencies, nominally 1, 2.5, and 4 MHz, have been...

Structural features of a bituminous coal and their changes during low-temperature oxidation and loss of volatiles investigated by advanced solid-state NMR spectroscopy Structural features of a bituminous coal and their changes during low-temperature oxidation and loss of volatiles investigated by advanced solid-state NMR spectroscopy
Quantitative and advanced 13C solid-state NMR techniques were employed to investigate (i) the chemical structure of a high volatile bituminous coal, as well as (ii) chemical structural changes of this coal after evacuation of adsorbed gases, (iii) during oxidative air exposure at room temperature, and (iv) after oxidative heating in air at 75 ??C. The solid-state NMR techniques employed...

Summary of the Second International Planetary Dunes Workshop: Planetary Analogs - Integrating Models, Remote Sensing, and Field Data, Alamosa, Colorado, USA, May 18-21, 2010 Summary of the Second International Planetary Dunes Workshop: Planetary Analogs - Integrating Models, Remote Sensing, and Field Data, Alamosa, Colorado, USA, May 18-21, 2010
The Second International Planetary Dunes Workshop took place in Alamosa, Colorado, USA from May 18-21, 2010. The workshop brought together researchers from diverse backgrounds to foster discussion and collaboration regarding terrestrial and extra-terrestrial dunes and dune systems. Two and a half days were spent on five oral sessions and one poster session, a full-day field trip to Great...

Tectonics of the Maryland Piedmont along the Potomac River; insight since 1960 and potential transfer to the Pennsylvania Piedmont Tectonics of the Maryland Piedmont along the Potomac River; insight since 1960 and potential transfer to the Pennsylvania Piedmont
This is a summary of a half century of research in the Mary land Piedmont and how it may or may not have implications for the Piedmont of Pennsylvania. Much of the field mapping and all of the isotopic analyses of rocks and minerals of the Maryland Piedmont have been conducted since the 1960 Field Conference of Pennsylvania Geologists “Some tectonic and structural problems of the...

The 7Q10 in South Carolina water-quality regulation: Nearly fifty years later The 7Q10 in South Carolina water-quality regulation: Nearly fifty years later
The annual minimum 7-day average streamflow with a 10-year recurrence interval, often referred to as the 7Q10, has a long history of being an important low-flow statistic used in water-quality management in South Carolina as evidenced by its adoption into South Carolina law in 1967. State agencies, such as the South Carolina Department of Health and Environmental Control and the South...

The Reimer Diatom Herbarium: An important resource for teaching and research The Reimer Diatom Herbarium: An important resource for teaching and research
The Reimer Diatom Herbarium (ILH) at Iowa Lakeside Laboratory (ILL), a field station of Iowa's state universities, contains 3,280 permanent diatom slides of collections made from prairie potholes, alkaline fens, acid bogs, eutrophic lakes, saline lakes, Pleistocene paleolakes, and Miocene fossil deposits near ILL. The herbarium has a focus on collections made within Dickinson County, a...
