Summary
Abstract: Sediment Recruitment Experiment 4 (SRE4) was a large, long term (5 year) field experiment run at Casey Station (from 2001 to 2006) testing the effects of 4 different hydrocarbons on marine sediment ecosystems. Four different types of hydrocarbons were individually mixed with defaunated marine sediments and deployed in trays on the seabed at O'Brien Bay-1. Trays were collected after deployment ...

Purpose: To determine the effects of hydrocarbons on marine sediment meiofaunal communities in Antarctica.

This is the dataset for meiofaunal communities in sediments in the experiment at Time 5 (5 years after deployment).

Only 2 replicates per tray (of each treatment) have been analysed. 2 replicates of each tray remain unsorted.

Quality Petrographic and chemical analyses were conducted on the collected samples.
Silicon dioxide (SiO2) content, indices of color, and hypabyssal equivalence
were determined. The modal composition of igneous rock samples on Robert
Island and Potter Peninsula was determined. Lava modal composition of
Bridgeman Island, Penguin Island, Deception Island and Howling Island was ... View entire text
