Abstract Seasonal mean total cumulative upwelling in the Agulhas Bank (33.3-37.5°S;18.5-27°E) shelf region during austral summer, autumn, winter, and spring.
Methods Daily-averaged NCEP-DOE Reanalysis 2 wind vectors were used to compute daily values of cumulative Ekman Transport (m3 s-1) per 100m of coastline (Lamont et al. 2018. JMS 188: 3-16). Monthly values were then computed by summing the daily values per month. Seasonal means were computed by averaging data over a three-month period for each season, defined as austral summer (December, January, February), autumn (March, April, May), winter (June, July, August), and spring (September, October, November). This data has been processed and published as Lamont et al. (2019) JGR Oceans, 124, 1170-1195 (https://doi.org/10.1029/2018JC014334) - please see this paper for a more detailed methodology.
