Absolute abundance of diatoms from CEAMARC cores
Listed in NASA Earthdata CMR
This data provides the absolute abundance of diatom valves from cores recovered from the George V coast as part of the CEAMARC (Collaborative East Antarctic Marine Census) mission of 2007-2008.
Description
Data are presented as valves/gram dry weight of sediment. All samples analyzed were core top samples, however no age constraints have been established.
Chaetoceros resting spores were included in the absolute abundance calculations. Slides were prepared following Rathburn et al 1997.
