南极海藻是高度耐荫的生物，可以在非常暗淡的光线下进行光合作用。这一显着的特征使它们能够在超过 30 m 的深度定居，并在极地冬季的长时间黑暗时期中生存下来。另一方面，它们能够很好地应对高光胁迫，这表明它们需要在荫蔽适应和有效的紫外线胁迫耐受性之间进行权衡。水的光学特性决定了光合作用的水下光气候以及海藻在其栖息地暴露于紫外线的风险。因此，了解水的光谱透明度的自然（空间、时间）和人为驱动的变化及其控制因素对于评估当前和未来环境情景下海藻的状态至关重要。本章总结了与决定南极海藻水下栖息地的光学特性有关的方面，以及由于气候变化、臭氧消耗和其他环境和新兴威胁及其相互作用而导致的水光学的潜在变化。
Antarctic seaweeds are highly shade-adapted organisms, which can photosynthesize under very dim light. This remarkable characteristic allows them colonizing over 30 m depths and surviving extended dark periods during the polar winter. On the other hand, they are well equipped to cope with high light stress, which points to a trade-off between shade adaptation and efficient UV stress tolerance. Optical properties of water determine both the underwater light climate for photosynthesis and the risk of seaweeds for UV exposure in their habitats. Thus, understanding the natural (spatial, temporal) and anthropogenic-driven changes in spectral transparency of water and factors governing it is fundamental in evaluating the state of seaweeds under current and future environmental scenarios. In the present chapter the aspects related to the optical properties determining the underwater habitat of Antarctic seaweeds are summarized, along with the potential changes in water optics as a result of climate change, ozone depletion and other environmental and emerging threats, and their interactions.
