Brief description

As part of MTSRF Task 2.5i.2, a range of indices were investigated to quantify upwelling on the central Great Barrier Reef (GBR), Australia. These indices are necessary for exploring environmental and biological relationships in areas where upwelling may be sporadic and less intense, especially along western boundary currents such as the East Australian Current. 'Upwelling days' (the number of days of upwelling, inferred from erratic downward temperature spikes) and diurnal variation in subsurface temperature (max-min, 20m depth) were found to be the best metrics to describe the duration and intensity of upwelling events, respectively. These were used to examine key characteristics of shelf-break upwelling in the central GBR. Temperature logger data (20m) were used to derive 'upwelling days' and the local mean summer temperatures (Dec - Feb) and NOAA AVHRR Pathfinder data were used to derive regional SSTs.

Notes

To investigate the best metrics to quantify upwelling and to explore relationships between these metrics, SST and coral bleaching.

Lineage

SST data derived from NOAA Pathfinder advanced high resolution radiometer sensors at a spatial resolution of 4 km (Kilpatrick et al. 2001; podaac.jpl.nasa.gov). Only the highest quality day + nighttime data were used (Quality flag 7). In situ temperature data collected using high-precision (0.02°C) dataloggers (Dataflow systems) at 1m and 20m depths. Loggers were calibrated/corrected to an accuracy of ±0.1°C.
