Global Technology Of Ocean Carbon Sequestration Based On Patent Analysis, Tianyue Peng, Dehao Tang, Liqiang Liu, Bing Han, Benduo Zhu

Bulletin of Chinese Academy of Sciences (Chinese Version)

The ocean is the largest and most active carbon reservoir in the world. Through ocean-atmosphere exchange and the photosynthesis of marine plants, the uptake of carbon dioxide (CO2) by the ocean is much greater than that by soil and vegetation on terrestrial areas. This is essential to mitigate and ameliorate today's global warming which is caused by rising atmospheric CO2 concentration. Therefore, to achieve the goal of "carbon neutrality" around the country, it is an effective approach to sequester CO2 in the ocean. This paper summarizes the technical application scope and methods of ocean carbon sequestration. By analyzing correlative patents …

Nutrient Dynamics And Ecosystem Development Of Urban Forests, Gisselle A. Mejía

Dissertations, Theses, and Capstone Projects

Urban growth and expansion are a major component of global environmental change, with impacts on climate, air and water quality, biodiversity, and human well-being. Forests embedded in urban landscapes are critical in mitigating these impacts at local, regional, and continental scales. However, assessing urban forests is difficult because cities are heterogenous in physical, chemical, biological, and social dimensions. This heterogeneity has constrained how urban forests are defined, and therefore, how they are studied. The objective of this dissertation is to determine how these biophysical and social factors drive ecological processes in urban forests and will address three outstanding challenges in …
