- Antarctic campaign
- Begin date: Sept 2003– end date: Oct 2003
- Polar zone: Ross Island
- Title: Aurora Australis V1 cruise
- Summary: This cruise is part of the SIBClim
project. In this collaborative work with the Australian glaciologists
from ACE (Drs. Ian Allison, Vicky Lytle, Rob Massom, Tony Worby)
we took the opportunity of the Aurora Australis V1 cruise (Australian
Antarctic Division) dedicated to sea ice remote sensing validation
(Antarctic Remote Ice Sensing Validation - ARISE) to collect
sea ice cores and perform in-situ measurements and experiments
(i.e. incubations). Eight stations were investigated, with
a total of 96 ice cores recovered (65 meters of cores) and
120 brine holes drilled. Some 560 liters of sea water and 180
liters of brines were collected and processed on board. About
20 CO2 flux measurements were performed above snow,
ice and brine holes and a total of 40 CO2 “spike” measurements
taken along depth profiles in the sea ice cover. Further analyses
are now performed in Brussels. Media considered are snow, ice,
brines (at two different levels), sea water. Variables measured
are: temperatures, bulk salinity, textures, δ18O, total
gas content, gas composition (O2, N2, CO2 ,DMS), Iron (total-dissolved-particulate-stable
isotopes), Nutrients, Chla, Pigments, Bacterial counting, Algae
speciation, Bacterial and algal viability, pH, Alkalinity,
pCO2 direct, pO2
