Correlation Figure (image) University of Texas at Austin Share Print E-Mail Caption A figure showing correlations between salinity in the Gulf of Mexico and rainfall on the continents in the modern era and the Little Ice Age. The colors represent rainfall (green is wetter conditions, brown is drier) and salinity (red is more saline conditions, blue is fresher). The modern era shows decadal-scale correlations between surface-ocean salinity in the northern Gulf of Mexico and salinity elsewhere in the oceans and rainfall on the continents. The shapes represent how data on rainfall during the Little Ice Age correlates with salinity data from the Gulf of Mexico from the same time period. The rainfall data was collected from proxy records, such as tree rings and cave formations, and the salinity data from sediment cores. Credit Thirumalai et all, 2018.
