Sea ice bio-optical measurements
Field-based sampling: As part of Australian Antarctic Science project # 4298, a total number of 44 sea ice sites were sampled for bio-optical measurements along 4 transects on... -
Effects of Enhanced UV-B on Sea Ice Algae
From the abstract of some of the papers: It has been suggested that increased springtime UVB radiation caused by stratospheric ozone depletion is likely to reduce primary... -
Response of antarctic marine diatoms to environment modification
Environmental manipulation and competition experiments on cultured and natural diatoms will identify the response of key taxa to environment modification. Understanding the... -
CO2 incubation data collected during the SIPEX II voyage of the Aurora...
Pulse Amplitude Modulation (WaterPAM, Walz) was used to measure the response of the sea ice brine microalgae to CO2 stress. All data was reported in WinControl software and... -
Role of micronutrients in the sea ice microbial ecosystem
The productivity of Antarctic waters may be controlled by the amount of iron. Experiments have shown that this is probably the case for phytoplankton but as yet we do not know... -
Parent metadata record for all metadata created from the SIPEX II voyage of...
More than 50 scientists from eight countries conducted the Sea Ice Physics and Ecosystem eXperiment 2012 (SIPEX-2). The 2012 voyage built on information and observations... -
Sea-ice core and under-ice optical measurements from ice stations conducted...
Sea-ice cores (0.09 m internal diameter) were sampled during Polarstern voyage PS117 to the Weddell Sea during December 2018 to January 2019. Ice core measurements include... -
Instrumented Remotely Operated Vehicle (ROV) under-ice observations
Data were collected during deployments of an instrumented Remotely Operated Vehicle on 5 sampling days to determine sea ice physical properties and measure transmitted under-ice... -
