Foraminifera, or forams for short, are ubiquitous in the world ocean (Sengupta, 1999). Along with their abundance, their biodiversity and extent of geologic record make their fossils of particular interest to paleontologists and paleoclimatologists (Schmiedl, 2019). The sand-sized fraction of deep sea sediments is often dominated by planktic foraminifera, of which there are about 50 extant species (Schiebel & Hemleben, 2017). Although modern benthic foraminiferal species number in the thousands, they are typically only abundant in shallow (shelf) environments and in poorly preserved abyssal sediments. For this work, we focus on deep-sea sediment and as such do not include analysis or commentary on benthic foraminifera. Due to the small size and great abundance of planktic foraminifera, hundreds or possibly thousands can often be picked from a single cubic centimeter of ocean floor mud. Foraminifera samples are normally sorted by species before they are used for either academic or
