EAGE Student Webinar
Student Webinar by Richard Rosas
OutlineThis talk involves the use of in-situ sensors to characterize surface seawater pH and to
understand how natural cycles influence its variability. While much research has focused on the
potential anthropogenic impacts on surface water pH, this presentation highlights how pH can
also shift due to natural processes such as excess photosynthesis or respiration, diurnal and
seasonal cycles, extreme weather events, and more.
The talk will draw on data collected from the Northwest Gulf of Mexico and the Southwest South
Atlantic to examine how both abiotic and biotic factors—ranging from differing water masses
and seasonal changes to biological interactions, diurnal patterns, and wind effects—contribute
to variations in surface seawater pH.
