Data sets

Intact polar lipid composition and bottom water and surface sediment characteristics during R/V Pelagia cruise PASOM to the Arabian Sea in 2009 Marc Besseling, Ellen C. Hopmans, Jaap S. Sinninghe Damsté, and Laura Villanueva

Short summary
Benthic archaea comprise a significant part of the total prokaryotic biomass in marine sediments. Here, we compared the archaeal diversity and intact polar lipid (IPL) composition in both surface and subsurface sediments with different oxygen regimes in the Arabian Sea oxygen minimum zone. The oxygenated sediments were dominated by Thaumarchaeota and IPL-GDGT-0. The anoxic sediment contained highly diverse archaeal communities and high relative abundances of IPL-GDGT-1 to -4.
