The Aquation Submersible Respirometer system was deployed at 14 m under the sea-ice at O’Brien Bay, East Antarctica (near Casey Station, Windmill Islands). The substrate at this location comprises many small rocks and boulders interspersed with irregular shallow patches of soft sediment, typically one to three meters across. previous studies have identified diatoms as the…
Read MoreThe Australian Antarctic Division is coordinating a field-based ocean acidification experiment in Antarctic waters near Casey Station, Windmill Islands, East Antarctica ( 66°17′ S 110°31′ E) this austral summer 2014-15. This antFOCE (antarctic Free Ocean Carbon Dioxide Enrichment) experiment will expose a range of benthic marine animals and algae to a constant supply of CO2-enriched…
Read MoreAquation has recently released a prototype version of its new Submersible Photosynthesis-Respiration System. This system measures the rate of production or consumption of oxygen in a submerged chamber, which provides a good proxy for photosynthesis and respiration rates. The System is only designed to operate two chambers, and is therefore easy to carry, setup and deploy. No…
