Understanding sporadic upwelling off the western Australian coast

Authors


Abstract

Ocean upwelling brings nutrient-rich deep waters to the surface, where phytoplankton can use the nutrients. Some coastal regions of the ocean have regular upwelling, but other regions, like the western Australian coast, have only sporadic upwelling events, which are ecologically important given a backdrop of low regional productivity. To study the factors influencing the seasonal variability of upwelling in the region, Rossi et al. analyzed satellite data covering 15 years, calibrating their approach using well-documented events.
