 This study found a positive correlation between in-situ seagrass temperatures and satellite-derived sea surface temperature from the Modi's and Landsat sensors along the Great Barrier Reef Coast in Australia, with Modi's SSD consistently higher than field measured temperatures. The approach could be used to monitor seagrass health over large areas if refined and tested further. This article was authored by S. R. Finn, E. M. Kovacs, C. M. Roelfsema and others.
