This
is a Thalassiosira valve and cingulum underneath, external surface. This image came
from JGOFS Benthic Cruise TT013, horizontal net haul at 9N,
140W, JD 340. This diatom is a well known member of the warm water Pacific diatom
plankton. They are heavily silicified
species seen in many sediment samples, thus they contribute to the carbon and
silica "expressway" from the surface to the seafloor.
