# = fractionated
The isotope curves did not show any typical glacial-interglacial trends and characteristics (difference 0.6 to 0.8 per mill only). The temperature effect (closeness to underwater volcanic activity, spreading center) may have influenced the isotope values. A hiatus was observed at 0.95 m (submarine slumps & slides). Moderate bioturbation was observed. […]
# 分馏（Fractionated）
同位素曲线（isotope curves）未呈现典型的冰期-间冰期（glacial-interglacial）趋势与特征（差值仅为0.6‰至0.8‰）。温度效应（受与水下火山活动、扩张中心（spreading center）的空间距离影响）可能对同位素数值产生影响。在0.95米深度处观测到沉积间断（hiatus），该现象由海底滑坡与滑移（submarine slumps & slides）所致。观测到中等程度的生物扰动（bioturbation）。[…]
