- Local conditions included sea surface temperature (SST), sea surface chlorophyll-a concentration (Chl-a), wind speed and wind direction. Meso-scale process included Bonney Upwelling sea surface temperatures (SST) over the austral summer (January–March) and large-scale processes included the Southern Oscillation Index (SOI) over a yearly period and the sea ice concentration in the Antarctic region. Significant results are indicated in bold and homogenous subsets (P > 0.05) are indicated by asterisks
