玛丽伯德地西部福特山脉冰川沉积物的地表暴露年龄表明，在过去的1万年里，南极西部冰盖在海岸附近持续变薄了700多米。在北半球，冰川消融比冰盖的消失晚了数千年，而且可能仍在进行中。这些结果提供了进一步的证据，证明南极西部冰盖的部分地区正处于长期下降的轨道上。南极西部的融化在全新世晚期为海洋贡献了水，并且可能在未来继续这样做。
Surface exposure ages of glacial deposits in the Ford Ranges of western Marie Byrd Land indicate continuous thinning of the West Antarctic Ice Sheet by more than 700 meters near the coast throughout the past 10,000 years. Deglaciation lagged the disappearance of ice sheets in the Northern Hemisphere by thousands of years and may still be under way. These results provide further evidence that parts of the West Antarctic Ice Sheet are on a long-term trajectory of decline. West Antarctic melting contributed water to the oceans in the late Holocene and may continue to do so in the future.
