Image of The Day caption:
Ellen Roosen (left) and Dan McCorkle retrieve a sediment core during a 2006 cruise aboard R/V Oceanus. The core contains fossil shells of single-celled organisms called foraminifera--"forams" for short. Some forams are abundant in the upper ocean and their shells rain down to become seafloor sediment, but other benthic species live on and in the seafloor, where the chemical composition of their shells record the temperature of the deep sea and hold clues to past water temperatures.
