Ross Sea/Ross Embayment diatoms in muds and diamictons

This data set includes data on late Quaternary marine diamictons and
muds. Data sets include (1) major and trace element geochemistry, and
(2) diatom data in several formats

Geochemistry:
1. Major and trace elements (ICP-AES, ICP-MS) from Ross Sea sediment

2. 10-Be concentration in Ross Sea and Ross Embayment sediment, sub
ice stream sediment and glacial ice

Diatoms:
1. Diatom counts from Ross Sea and Ross Embayment sediment cores
(Sjunneskog and Scherer, 2004)
a. diatom species counts
b. diatom absolute abundance data (valves per gram dried sediment)
c. abundance of diatom fragments

2. Diatom abundance and fragmentation patterns resulting from
controlled compaction and internal shearing (Scherer, Sjunneskog,
Iverson, Hooyer, 2004a; 2004b)
