  abstract = {{T}he eddy field in the {A}rabian {S}ea experiences seasonal wind-driven intensification during the summer monsoon season from {J}une through {S}eptember. {T}hese strong eddies strengthen local currents like the {S}omali {C}urrent and strongly impact regional upper-level vertical and lateral advection. {T}o investigate the multivariate response to eddying, we apply a closed-contour eddy-tracking algorithm to sea level anomaly maps and then examine sea surface temperature and salinity of the identified eddies to infer whether they are surface or subsurface intensified in the {A}rabian {S}ea during the summer monsoon. {A} complete understanding of the temperature and salinity signatures reveals how {A}rabian {S}ea eddies alter upper-ocean stratification. {T}hough both intensification types are identified, we find a dominance of likely surface-intensified eddies characterized by relatively warm and fresh cores for anticyclonic eddies and relatively cool and saline cores for cyclonic eddies, particularly in the northwestern {A}rabian {S}ea and {S}omali {C}urrent region. {P}lain {L}anguage {S}ummary {M}esoscale eddies in the ocean, analogous to their atmospheric cyclone and anticyclone counterparts, play a major role on the transport and redistribution of oceanic properties like heat or salt. {T}hey are highly variable and transient, so to fully understand their behavior, eddy tracking algorithms are typically used to identify these features and follow their trajectories. {I}n this study, we apply an algorithm to sea level anomalies in order to track eddy formation, distribution, and duration during the summer monsoon season in the {A}rabian {S}ea. {I}n sea surface height, cyclonic (anticyclonic) eddies appear as low (high) sea level anomalies. {T}hough the overall displacement of the eddy can be estimated with sea level anomalies alone, a more in-depth investigation of the temperature and salinity at the surface and subsurface can provide insight to the vertical structure of the eddy. {M}ore specifically, a multiparameter approach allows for investigation of whether an eddy intensifies at or below the surface. {T}his research analyzes the characteristics of eddies in the {A}rabian {S}ea during the southwest monsoon seasons from 2015 to 2018.},
