As living organisms, planktonic foraminifera are not passive tracers of the environment. Their test geochemistry—arguably the single most important resource for paleoceanographic research—reflects the combined signal of environmental, biological, and preservational processes. For most species, comparisons of test stable isotopic composition within and among taxa provide the primary means for di...

Coral geochemical climate reconstructions can extend our knowledge of global variability and trends over time scales longer than those instrumental data. However, such be biased by coral growth skeletal architecture, as troughs, off-axis corallite orientation, changing direction. This study quantifies the impact architecture on geochemistry using measurements density, extension rate, calcificat...
