This dataset consists of seawater Mg/Ca and Sr/Ca ratios, temperature, salinity, total alkalinity, DIC and DO measured from 79 cruises between 2009 and 2017. The long debate about the conservative behaviour of seawater Mg/Ca and Sr/Ca ratios becomes more complex by studying the ocean as a whole and not only open ocean settings or the deep sea. In this project we measured in 79 cruises around the world seawater Mg/Ca and Sr/Ca ratios to discover that the modern ocean ranges are well beyond the pre-assumed values used by modellers, paleoceanographers and experimentalists as the basis for their work (Mg/Ca = 4.5 to 6.5 mol:mol and Sr/CA = 7 to 9.8 mmol:mol). We find out that modern seawater ranges are similar to the last 20 million years (Neogene) increase in these ratios, challenging the pre-assumed knowledge and a good number of methods used that assume a constant seawater Mg/Ca or Sr/Ca ratio. We agree that open ocean, the deep sea and reconstructions of past seawater based on samples derived from these settings give a good representation, but by no means they represent the ocean as a whole, especially coastal areas, upwelling zones, polar waters, and even the euphotic zone.
