Report of the River Master of the Delaware River for the period December 1, 2011–November 30, 2012 Report of the River Master of the Delaware River for the period December 1, 2011–November 30, 2012
A Decree of the Supreme Court of the United States, entered June 7, 1954, established the position of Delaware River Master within the U.S. Geological Survey. In addition, the Decree authorizes diversion of water from the Delaware River Basin and requires compensating releases from certain reservoirs, owned by New York City, to be made under the supervision and direction of the River...

National assessment of carbon dioxide enhanced oil recovery and associated carbon dioxide retention resources — Results National assessment of carbon dioxide enhanced oil recovery and associated carbon dioxide retention resources — Results
In 2020, the U.S. Geological Survey (USGS) completed a probabilistic assessment of the volume of technically recoverable oil resources available if current carbon dioxide enhanced oil recovery (CO2-EOR) technologies were applied to amenable oil reservoirs underlying the onshore and State waters areas of the conterminous United States. The assessment also includes estimates of the mass of...

Five years of monitoring a bio-engineered living shoreline: Comparison of oyster population development by reef technology. Five years of monitoring a bio-engineered living shoreline: Comparison of oyster population development by reef technology.
The Living Shoreline Demonstration Project (PO-148) used five bio-engineered reef technologies (Reef Balls in two configurations; Figure 1) acting as breakwaters to protect vulnerable shorelines. While the primary goal is to attenuate wave energy, the sustainability and success of these products as “living” shorelines are based on their ability to enhance oyster habitat, enabling the...

Automating the detection and classification of wildlife in aerial imagery by developing a framework to support machine learning techniques Automating the detection and classification of wildlife in aerial imagery by developing a framework to support machine learning techniques
This report presents a collected effort to construct a framework that supports machine learning techniques for wildlife surveys using digital aerial imagery. A robust foundation has been developed to advance both scientific and production-ready applications of Artificial Intelligence/Machine Learning (AI/ML) for wildlife surveys by constructing a data pipeline to handle large image...

Simulation of groundwater and surface-water resources of the San Antonio Creek Valley watershed, Santa Barbara County, California Simulation of groundwater and surface-water resources of the San Antonio Creek Valley watershed, Santa Barbara County, California
In the San Antonio Creek Valley watershed (SACVW), western Santa Barbara County, California, groundwater is the primary source of water for agricultural irrigation, the town of Los Alamos, and supplemental water to Vandenberg Space Force Base (VSFB). Groundwater pumpage has increased since the 1970s as non-irrigated agricultural land has been converted to irrigated land and as local...

Climate change adaptation thinking for managed wetlands Climate change adaptation thinking for managed wetlands
Climate change presents new and ongoing challenges to natural resource management. To confront these challenges effectively, managers need to develop proactive adaptation strategies to prepare for and deal with the effects of climate change. We engaged managers and biologists from several midwestern U.S. Fish and Wildlife Service field stations to understand recent and future climate...

Hydrogeologic characterization of the San Antonio Creek Valley watershed, Santa Barbara County, California Hydrogeologic characterization of the San Antonio Creek Valley watershed, Santa Barbara County, California
The San Antonio Creek Valley watershed (SACVW) is located in western Santa Barbara County, about 15 miles south of Santa Maria and 55 miles north of Santa Barbara, California. The SACVW is about 135 square miles and encompasses the San Antonio Creek Valley groundwater basin; the SACVW is separated from adjacent groundwater basins by the Casmalia and Solomon Hills to the north, and the...
