Heterozoan carbonates from the equatorial rocky reefs of the Galápagos Archipelago

Strongly influenced by seasonal and interannual (i.e. El Niño-Southern Oscillation) upwelling, the equatorial setting of the Galápagos Archipelago is divided into well-defined temperature, nutrient and calcium carbonate saturation (?aragonite) regions. To understand the relationship between oceanographic properties and sediment grain associations, grain size, carbonate content and componen
