Abstract:
Uncertainty in satellite-derived burned area estimates are especially high in grassland systems, which are some of the most frequently burned ecosystems in the world. In this study, we compare differences in predicted burned area estimates for a region with the highest fire activity in North America, the Flint Hills of Kansas, USA, using the moderate resolution imaging spectroradiometer (MODIS) MCD64A1 burned area product and a customization of the MODIS MCD64A1 product using a major ground-truthing effort by the Kansas Department of Health and Environment (KDHE-MODIS customization).

Nine years after a wildfire, above- and below-ground morphology of Pinus brutia Ten. saplings and the microsite factors prevailing in understorey (unburned area) and postfire conditions (burned area) of the Forest Park of Thessaloniki were studied. Major stand characteristics (density, tree canopy cover, tree height, crown height, and diameter) were measured in the unburned area. Light and soil conditions as well as plant cover of woody species were recorded in both areas (burned and unburned). A random sample of pine saplings, of uniform age, was taken from both burned and unburned areas, and

AbstractGround-penetrating radar (GPR) has become a common method for mapping archaeological sites in the American Southwest. A less tested use for this method is to survey architectural spaces within larger pueblos to map features that may relate to the function, use, and abandonment of a specific room. In Chaco Canyon, GPR was used in a room (Room 28) within Pueblo Bonito prior to excavation to determine the presence and depth of buried features. Comparison with excavation results provides a means to evaluate how well this method mapped features in this small space. Three categories of featu

Abstract:
Man-made fires are frequent during the dry season in grasslands of the páramo ecosystem of equatorial Andes, at elevations above 3400 m above sea level. They have the short-term effect of biodiversity loss and soil erosion, and the medium to long-term impact of leaving more available niches, resulting in changes in the ecosystem structure. This study aimed to understand the effects of these fires on ground beetle populations. The study area was on Cerro Atacazo where 300 ha were burned in July 2017. Samplings were made in a burned area and an adjacent unburned area at ca. 4000 m above sea leve

Pre- and post-fire airborne lidar data provide an opportunity to determine peat combustion/loss across broad spatial extents. However, lidar measurements of ground surface elevation are prone to uncertainties. Errors may be introduced in several ways, particularly associated with the timing of data collection and the classification of ground points. Ground elevation data must be accurate and precise when estimating relatively small elevation changes due to combustion and subsequent carbon losses.

Abstract:
Our Inventory & Monitoring team surveyed over 200 Terrestrial Native Vegetation Monitoring Plots in the Santa Monica Mountains and Simi Hills (SAMO) Region over the first seven years of this program?s history, 2014?2020. During this period, the park experienced a large wildfire in 2013 followed by historic drought, and then in 2018 the largest wildfire in the region?s recorded history, succeeded by well-timed rainfall. The goal of this monitoring program is to detect and understand the nature of vegetation change, for example in drought or post-fire environments, providing a knowledge base

Abstract:
The Sonoran Desert Network (SODN) conducted an inventory, classification, and mapping of vegetation communities at Chiricahua National Monument (CHIR) from 2007 to 2011. This report is Volume I of two volumes, summarizing 29 vegetation communities (associations) identified at the monument and providing them within the context of the United States National Vegetation Classification (USNVC), the hierarchical system guiding all National Park Service (NPS) vegetation inventories. Volume II contains the full association descriptions. The project combined existing plot data with new plot-scale and l

Full text
Abstract:
The detection and location of buried underground or submerged underwater pipes is of importance to the utility, natural gas, and petroleum industries. Current detection and location methods include ground penetrating radar (GPR), ground conductivity measurements, and magnetometers. GPR presents numerous problems, including signal attenuation in the ground and the presence of ground clutter. Ground conductivity measurements require that electrodes be planted in the ground and results may be affected by ground conditions. Magnetometers can detect ferrous pipes, or pipes with ferrous taggants, si

Abstract:
Presents a state-of-the-art review of the technologies available for stress measurement in buried pipelines and recommendations regarding further development of such technologies appearing to have favorable application for natural gas transmission service. The technologies are grouped in terms of internal inspection devices, devices requiring external access to the pipe, and those that may be inserted from the ground on the pipeline right of way.

Full text
Abstract:
This project considers some of the geotechnical and geothermal engineering issues that will need to be considered for the design and construction of large diameter gas transmission pipelines from the arctic production areas to southern markets. The challenges relate to determination of the frost heave and thaw settlement behaviour of a pipeline as it crosses from areas of continuous permafrost, through discontinuous zones to completely unfrozen ground conditions. The use of chilled gas will overcome some problems in already frozen ground but will cause frost heave where a frost bulb is formed

Abstract:
Reviews the available sensors for monitoring hazardous ground movement. Our review was limited to airborne and spaceborne sensors for access, performance, and productivity considerations. It was observed that certain ground movement is comparatively localized, e.g., earthquake faulting, while other activity may extend for thousands of kilometers, e.g., frost heave. Accordingly, we have considered two operating modes for the sensor-platform system, namely, site-by-site and continuous corridor. To determine the suitability of the candidate sensors for pipeline monitoring, we have assessed the ex

Full text
Abstract:
Occasionally, buried explosives are used within proximity of producing oil and gas wells which increases the stresses in the casing near the explosion which may result in failure of the well. A procedure was needed for predicting the maximum stresses in producing oil and gas wells, specifically the well casing, induced by nearby, buried, explosive detonations. An extensive experimental and analytical program were funded and performed over a six (6) year period 1975-1981. The program was divided into two (2) parts: In the first part, similitude theory, empirical analyses and test data were used
