Abstract Oil and gas production regions are significant sources of greenhouse gases and reactive pollutants such as nitrogen oxides (NOx) and volatile organic compounds. Research has also shown that methane (CH4) emissions reported to the Environmental Protection Agency's (EPA) Greenhouse Gas Reporting Program (GHGRP) are generally underestimated. The Arctic accounted for 5.5% of global oil and gas production in 2022 but is estimated to contain significant undiscovered resources. The emitted NOxand volatile organic compounds can impact the composition and chemistry of the Arctic atmosphere. The Prudhoe Bay Oil Field in Alaska is one of the 10 largest oil fields in the US and has been approved for significant development expansion. However, only one recent study has reported measurements of its greenhouse gas emissions. We estimate the emission rates for carbon dioxide (CO2), CH4, and NOxfrom the Prudhoe Bay Oil Field during the spring of 2022 using airborne mass balance methods and emission ratios. We also discuss emissions per energy produced and show an increase over time, with values higher than the national average for oil and gas producing regions, though within uncertainties. Our estimates are lower than the NOxemission estimate reported in the National Emissions Inventory (NEI), as seen in other oil and gas studies, but fall within the uncertainty range of the greenhouse gases reported in the GHGRP. This work provides a valuable snapshot of emissions before further expansion of extraction activities.

                            Nitrogen-hungry bacteria added to farm soil curb greenhouse-gas emissions
                        
                    
    
            Innovative solutions are needed to decrease greenhouse-gas emissions. Field trials show that supplementing farm soil with a bacterium that consumes the greenhouse gas nitrous oxide can substantially lower harmful emissions.

            The objective of this research is to evaluate the effects of cropping choices on land, water use for irrigation, and greenhouse gas emissions after introducing canola (Brassica napus L.) cultivation for the production of 60 million gallons of biodiesel per year. Characterization of regional farm-level cropping patterns and agronomic inputs and economic data are used to model the adoption of canola in place of the diverse incumbent cropping patterns in four regions of California: Northern and Southern San Joaquin Valleys, Sacramento Valley, and Southern California, using the Bioenergy Crop Adoption Model. The life cycle assessment approach is then used to assess environmental impacts due to cultivation of canola in place of the incumbent cropping patterns in terms of: (1) land use; (2) life-cycle greenhouse gas emissions due to direct land use change (kg CO2e ac-1); (3) greenhouse gas emissions due to irrigation water (kg CO2e ac-1); and (4) life-cycle greenhouse gas emissions expressed in grams of carbon dioxide equivalent per megajoule of biodiesel. Preliminary results show the adoption price of the canola with a yield of 1.5 U.S. tons per acre is estimated to be $481 per ton of canola in 2012 dollars at which point a total of 508,400 acres appear in canola cultivation. This land area (508, 400 acres) is equivalent to approximately 89 million gallons of biodiesel from canola per year given the assumptions stated in this study. Consequentially, crops that are less profitable are replaced with canola and greenhouse gas emissions due to irrigation water are reduced while maintaining a diversified percentage of the incumbent cropping patterns, as well as canola cultivation.more » « less

            To investigate the effect of a winter with decreased snow cover on greenhouse gas emissions, we experimentally removed snowfall from a small dystrophic lake in northern Wisconsin. As a comparative study, we were able to explore the role of light in under-ice gas dynamics and spring emissions in dimictic lakes. This dataset contains greenhouse gas and temperature/dissolved oxygen profile data collected on South Sparkling and Trout Bog during the winter of 2020 through the winter of 2021. Data were collected between 09 January 2020 and 13 April 2021 in the deep hole of both bogs. Dissolved greenhouse gas concentrations of carbon dioxide and methane were measured using the headspace equilibrium method.more » « less

            Improving the management of nitrogen fertilizer makes sense. It can reduce farm costs by increasing nitrogen use efficiency without reducing yields. It can also benefit our environment by reducing the emissions of a potent greenhouse gas called nitrous oxide. Better still, by improving nitrogen management, farmers can receive payment for reducing emissions of this gas through the market place. Agriculture is a source and a sink for greenhouse gases that affect our climate. All three of the major greenhouse gases are produced naturally in agricultural soils—carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). Nitrous oxide is the most important in all field crops but rice due to its link with the use of nitrogen fertilizer.more » « less
