Statement

This study used two daytime sea surface temperature (SST) products (AVHRR and MODIS) to define marine thermal fronts. AVHRR SST product was obtained by Australia's Integrated Marine Observing System (IMOS) from the National Oceanic and Atmospheric Administration (NOAA) Advanced Very High-Resolution Radiometer (AVHRR) on all available NOAA Polar-orbiting Operational Environmental Satellites (POES). It was downloaded from the Australia Ocean Data Network (AODN). It is a six-day average SST product and with 1.1 km spatial resolution. Time ranged from 1993 to 2018. MODIS SST product with a 4×4 km spatial resolution was obtained from the NASA EOSDIS Physical Oceanography Distributed Active Archive Center (PO.DAAC) from NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite. It is an eight-day average SST product. Time ranged from 2003 to 2018 Two algorithms were used to define marine thermal fronts: the adaptive Canny gradient-based edge detection algorithm and the Cayula and Cornillon single image edge detection (SIED) algorithm. The detected frontal maps were used to calculate the probability of frontal encounter (PFE) and frontal density (FD). The application of the Cayula and Cornillon SIED method was achieved by using an available ArcGIS Toolbox (Marine Geospatial Ecology Tools, MGET), so it won't be involved in this record.
