Natural Climate Solutions: Understanding the conditions that facilitate resilient ecosystems

Although coastal wetland ecosystems are important globally for their capacity to sequester and store carbon (C), many ecosystems are at risk due to climate change and sea level rise. In one of the most dynamic coastal wetland complexes in the world, the Florida Everglades, changes in freshwater supply and accelerated rates of salt water intrusion are changing the structure and function of important ecosystems.  The Everglades Eddy Covariance Tower Network is positioned to measure the effects of disturbances and changes in hydrology. Tower locations provide an opportunity to quantify trends in productivity and develop models to estimate the source/sink potential of the Everglades landscape and how it is changing.

    Methane Plume Mapping Over Offshore Oil and Natural Gas Platforms in the Gulf of Mexico

    Abstract

    Offshore oil and natural gas platforms are responsible for about 30% of global oil and natural gas production. Despite the large share of global production there is little known about the greenhouse gas emissions from these production facilities. Given the lack of direct measurements, studies that seek to understand the greenhouse gas contribution of offshore oil and gas platforms are incredibly important. The use of airborne remote sensing to map greenhouse gases from onshore oil and gas infrastructure has become a prominent method to quantify and attribute large individual emissions to their sources. However, until now, this method has not been used offshore due to the lack of consistent reflected radiance over water bodies.  In this talk I will present the results from a 2021 study where we used visible/infrared imaging spectrometer data collected over the Gulf of Mexico to map methane emissions from shallow water offshore oil and natural gas platforms. I will discuss the methods we employed to map methane in the offshore environment and how that differs from the onshore environment. I will show how remote sensing can efficiently observe offshore infrastructure, quantify methane emissions, and attribute those emissions to specific infrastructure types.
