This review collates research into fine sediment as a stressor of seagrass and emphasizes the multiple modes of action of this contaminant. The article is based on a bibliographic database search that identified 201 articles describing sediment impacts on seagrasses. Articles were classified by one of three non-exclusive modes of action: 1) light reduction; 2) smothering (burial), and 3) effects via rhizosphere physico-chemistry. Most citations (104) investigated multi-mode impacts of sediments, but the most frequently investigated single mode was light reduction (57 citations), followed by substrate rhizosphere chemistry (31) then smothering effects (6). Mud with high organic content is particularly problematic and smaller seagrasses are particularly vulnerable. Research gaps include polyphasic approaches, and studies of interactions between smothering, rhizosphere biogeochemistry and light climate. Identifying the thresholds of seagrass health indicators under mud stress should benefit coastal resource management, enabling improved decision-making and implementation of protective actions.

这篇综述整理了对细沉积物作为海草压力源的研究，并强调了这种污染物的多种作用模式。该文章基于书目数据库搜索，该搜索确定了 201 篇描述沉积物对海草影响的文章。文章按以下三种非排他性作用模式之一分类：1) 减光；2) 窒息（掩埋），和 3) 通过根际物理化学的影响。大多数引用 (104) 研究了沉积物的多模式影响，但最常研究的单模式是光减少 (57 次引用)，其次是基质根际化学 (31)，然后是窒息效应 (6)。有机物含量高的泥浆尤其成问题，而较小的海草则特别脆弱。研究差距包括多相方法、和研究窒息、根际生物地球化学和光气候之间的相互作用。确定泥浆压力下海草健康指标的阈值应该有利于沿海资源管理，从而改进决策和保护行动的实施。
