Research The Climate Of Antarctica
The climate research of P&O Polar examines the role of the southern ocean and Antarctica in the world’s climate system. This research’s focus has always been to address the uncertainties that have been identified in the assessment report of the IPCC. The report brought to the fore the lack of pertinent data on climate from the sea ice, southern ocean and Antarctica. The report also noted the urgency in understanding the region’s role in climate change, particularly as it slows climate change’s rate and, of course, ice sheet behaviour and its contribution to the rise of sea level.
In carrying out our climate research, examination inquiries to be researched include:
- What are the cycles controlling ice misfortune from the ice sheet in both East and West Antarctica, and how might these impact future ocean level ascent?
- Is the ‘worldwide upsetting course’ (dissemination of the world’s seas) prone to change with future warming, and what effect will this have?
- What amount of warmth and carbon will the Southern Ocean have the option to take up and store later on?
- Is the improvement of better atmosphere framework models repressed by helpless comprehension of certain high scope (polar) barometrical cycles?
- What can the record of past atmospheres educate us regarding current and future environmental change?
Ice Sheets & Rise In Sea Level
On Ice sheets & rise in sea level, our examination seeks to improve the assessments of ice misfortune from the Antarctic ice sheet for a fuse in ocean level projections for 2050, 2100 and beyond. It will zero in on:
- What cycles control ice misfortune from the Antarctic ice sheet, and how might this impact future ocean level ascent?
- What is the current state and pace of progress of Antarctic ice mass?
To respond to these inquiries, our researchers will:
- utilise long haul satellite estimations and new distant detecting advances to gauge the ‘mass financial plan’ (gain and loss of ice) of the ice sheet
- utilise airborne geophysical overviews to procure information that gives a superior comprehension of conditions underneath the ice sheet and ice racks, for example, the collaborations between the sea, ice racks and ice sheet streams
- gather proof of over a wide period ice sheet positions
- utilise this data to improve PC models that can repeat the inconstancy and history of significant ice sheets and give more exact projections of future change.
On atmosphere, our exploration intends to improve:
- comprehension of ‘teleconnections’ (where climate changes at one area are connected to changes somewhere else) among Antarctic and Southern Ocean climate frameworks, to give information to climate forecasts and atmosphere projections for Australia;
- comprehension of the associations between ozone focuses and attributes of the polar vortex (a district in the stratosphere, 15–50km up, where solid breezes around the shaft forestall air blending in with the remainder of the climate). This will help us project the atmosphere framework reaction to ozone recovery, and changes to wind examples and tempest frequencies at high southern scopes;
