Ningaloo sea surface temperatures (SST)

Sea surface temperature (SST) is the water temperature close to the ocean’s surface.  SST’s are generally measured using weather satellites, and are central to interactions of the ocean and the atmosphere that control climate and weather.  As such, tropical storm and cyclone formation are strongly influenced by SST, ocean nutrient concentrations and primary production are correlated with SST, and coral bleaching events are usually caused by long periods (usually 4 to 8 weeks) of warmer than average summer SST’s.

While in situ sea temperature measurements have a number of advantages (e.g. site specificity, temperature change with depth, continual temperature measurements etc.), the costs of purchase, deployment and retrieval, coupled with logger malfunctions, often render in situ measurement data difficult to access.  SST’s on the other hand, while only giving data on the surface temperatures, are available daily, and therefore provide useful spatial and temporal temperature data sets.

Three SST data sets are available for Ningaloo (see Excel spreadsheet below).
