In this paper, we present an economic analysis of CO2-enhanced oil recovery (EOR). This technique entails injection of CO2 into mature oil fields in a manner that reduces the oil's viscosity, thereby enhancing the rate of extraction. As part of this process, significant quantities of CO2 remain sequestered in the reservoir. If CO2 emissions are regulated, oil producers using EOR should therefore be able to earn revenues from sequestration as well as from oil production. We develop a theoretical framework that analyzes the dynamic co-optimization of oil extraction and CO2 sequestration, through the producer's choice of the fraction of CO2 in the injection stream at each moment. We find that the optimal fraction of...

These data were compiled as part of a larger study to evaluate post-stocking survival of hatchery-reared Roundtail Chub. We conducted a two year study (Dec. 2015 – Mar. 2017) in the upper Verde River at the Burnt Ranch stocking location near Paulden, Arizona. Young of year Roundtail Chub were acquired from the Arizona Research and Conservation Center in Cornville, Arizona. Passive integrated transponder (PIT) tags (BioMark, 12.5 mm 134.2 kHz FDX) were implanted into Roundtail Chub each year (n = 333, Year 1; n = 2177, Year 2) prior to stocking. Each year, fish were measured (total length, TL, mm) before release (reflected in Pre-Stocking data table). We used two methods to recapture stocked fish, one passive and...

Additional data layers have been developed to supplement recently published information collected and developed for an investigation of shoreline erosion along the Lower Brule Reservation in Central South Dakota. The additional data layers presented in this data release include georeferenced 1965 single frame aerial photos, digitized shoreline features from the georeferenced 1965 images, digitized shoreline features from 2016 aerial imagery, and real-time kinematic surveys of shoreline features on selected reaches of the Lake Sharpe shoreline in 2018. This effort was completed by the USGS Dakota Water Science Center in cooperation with the Lower Brule Sioux Tribe, Tribal Preservation Office.

This data represents areas of forest damage due to insect infestation, fire, flood, landslides, windthrow and other mortalities. The information was collected by aerial surveys by both the USFS and ADNR, Div. of Forestry in cooperation with the Forest Health Protection (FHP) project. Surveys are conducted in July and August so that pest "signatures" may be obtained during the optimal period for symptom development of ocular estimation. The aerial survey is coordinated with known pest outbreaks so that the maximum extent of recent bark beetle damage (fading trees) and insect defoliation (discoloration, foliage loss) patterns may be determined. Aerial survey flights are termed as "local" if they can be completed...

This dataset contains polygons describing photo interpreted map classifications of the Tongass National Forest developed in 1978. The dataset's primary objective was to delineate major land types and their attributes. The land types were mapped at a polygon level - areas generally homogenous in character. Mapping was done to a 10 acre minimum except for non-commercial and non-forest types which were mapped to a 5 acre minimum. The classification identifies water as well as land. It segregates land into non-forest and forest. Polygons in forested areas were assigned a single, representative set of attributes; species composition, age, and volume class. Tim86 was updated in the 1980's (mostly in 1986) to reflect timber...
