Analysis of MAB EOF, EL, and GOM Oscillator for Current Variability in Larger Domains

This work details a comprehensive analysis of the MAB EOF for the EL and (U,V) current across a larger domain, focusing on data from 1993 to 1999. It includes a thorough examination of GOM oscillator dynamics without wind influences, analyzing significant variations over the years 2000 to 2007 using composite data sets. The study covers periods with and without eddies, assessing phase shifts and volume transport dynamics within the domain, and presenting visual data representations every five days.
