Identification is based on water mounts of both live and preserved material.
Species-level identification of many taxa requires further special preparation. Dinoflagellates can be stained to enhance the visibility of plate structure, or examined in the scanning electron microscope. This level of investigation is outside of the scope of our funded research, therefore some taxa on this list have only been identified to generic level at this time. Actinoptychus senarius Asterionellopsis glacialis Biddulphia spp. Chaetoceros eibenii Chaetoceros cf.
