Wavelength- and temperature-dependent apparent quantum yields (AQYs) for the photochemical production of acrylate in seawater

Abstract

This dataset includes wavelength- and temperature-dependent apparent quantum yields (AQYs) for the photochemical production of acrylate in 0.2-micrometer (µm) filtered seawater samples collected from coastal Rhode Island (USA), the Sargasso Sea, and two sites in the Pacific Ocean off the island of Mo'orea (French Polynesia). These data were determined using (1) a monochromatic irradiation system and (2) a Shimadzu high-performance liquid chromatography system with a UV-Vis absorbance detector.

This dataset was collected by Dr. Lei Xue under the supervision of Dr. David Kieber at the State University of New York, College of Environmental Science and Forestry. These data were used to construct a global model of the depth-dependent photochemical production of acrylate in seawater. This work is part of a larger study to understand the role of photochemistry in the turnover of dissolved organic matter in the oceans.
