Overview

ROICE 2016 continued the first expedition with a more precise sampling strategy.

Organized by INCDSB with governmental and Romanian Academy support, the campaign used field mapping and preliminary ROICE 2015 results to broaden research at King Sejong Antarctic Station on King George Island.

Scientific Objectives

01

Continuity

Continue the INCDSB-KOPRI bilateral scientific collaboration and ROICE 2015 direction.

02

Climate effects

Investigate climate change effects on microbial communities and glacial ecosystems.

03

Stable isotopes

Analyze the King George Island hydrological network in relation to microcosm diversity.

04

Human adaptation

Study erythrocyte viability and pre-/post-expedition physiological changes.

Field and Laboratory Activities

Samples moved from Antarctic field sites into molecular and geochemical workflows.

The team collected water, ice, subglacial water, snow and soil, then filtered samples for DNA extraction, chemical analyses and low-temperature cultivation.

Sampling

Field network

Approximately 50 locations across King George Island habitats.

Processing

Station lab

Around 300 samples processed at King Sejong Research Station.

Analysis

Integrated workflows

SEM, 16S rRNA, LSU rRNA, Illumina MiSeq, bioinformatics and diversity-chemistry correlations.
