Climate change puts Australia at risk from sea level rise and an increase in the occurrence and intensity of droughts. We need to learn about issues concerning the water cycle that are still poorly understood, such as whether droughts cause a reduction in only surface water or also water stored in underground reservoirs and what happens to ocean waters when thermal expansion causes an increase in sea surface height in some regions but not others. This proposal will provide new and accurate scientific information on the risks of sea level rise through the effects of thermal expansion of the oceans, in particular in shallow coastal zones. It will help us to understand droughts, variations in water resources and groundwater recharge patterns.

气候变化使澳大利亚面临海平面上升以及干旱发生和强度增加的风险。我们需要了解有关水循环的问题，但人们对此知之甚少，例如干旱是否仅导致地表水减少，还是地下水库中储存的水也减少，以及当热膨胀导致某些地区而非其他地区海面高度增加时，海水会发生什么变化。该提案将为海洋热膨胀影响导致海平面上升的风险提供新的、准确的科学信息，特别是在浅海沿海地区。它将帮助我们了解干旱、水资源变化和地下水补给模式。
