摘要

海洋底混合层是海洋底层水体中受强湍流混合作用影响的水层，其作为海洋物理、化学和生物过程交汇的重要界面，在全球海洋能量、物质交换和生物地球化学循环中扮演着关键角色。本文系统综述了海洋底混合层的研究进展，重点探讨了其结构特征、影响机制、厚度的确定及参数化方法以及全球海洋底混合层厚度分布规律，并展望了其未来研究方向。详细分析了底混合层温度、盐度和密度在垂直方向的结构；探讨了底层剪切流引发湍流破坏水体密度层结、内波破碎产生强湍流混合、地形改变底层流流速方向并增大流速梯度、潮汐作用周期性调节底层流流速和流向、地热通量加热底层海水减弱层结稳定性等多种影响机制；介绍了阈值法、曲率法、最大角度法和相对方差法等确定海洋底混合层厚度的方法，并讨论了底混合层厚度与海水深度和湍流扩散系数呈正相关、与浮力频率呈负相关等参数化关系；总结了全球大洋底混合层厚度分布不均匀性特征，洋中脊附近较厚，大西洋、印度洋和太平洋的底混合层厚度中值分别为40 m、42 m和64 m，全球中值为47 m；最后对海洋底混合层未来的研究手段和研究方向做出了展望，提出需发展深海坐底潜标、自主水下机器人等先进观测技术，加强底层流剪切、内波破碎和地形效应相互作用的理论研究，发展底混合层精细数值模拟等方法。

Abstract

The ocean bottom mixed layer (BML) is a water layer near the seabed influenced by intense turbulent mixing

serving as a critical interface where physical

chemical

and biological processes converge. It plays a key role in global ocean energy and material exchange

as well as biogeochemical cycles. This paper systematically reviews the research progress on the BML

focusing on its structural characteristics

influencing mechanisms

methods for determining and parameterizing its thickness

and the global distribution patterns of BML thickness. Furthermore

future research directions are outlined. The vertical structures of temperature

salinity

and density within the BML are analyzed in detail. The influencing mechanisms are explored

including turbulent mixing induced by bottom shear flows disrupting density stratification

strong turbulence generated by internal wave breaking

topographic effects altering flow velocity and direction while enhancing shear

tidal forces periodically modulating near-bottom currents

and geothermal heating reducing stratification stability. Various methods for determining BML thickness are introduced

such as the threshold method

curvature method

maximum angle method

and relative variance method. Parameterization relationships are discussed

indicating that BML thickness is positively correlated with water depth and turbulent diffusivity but negatively correlated with buoyancy frequency. The global distribution of BML thickness exhibits significant heterogeneity

with thicker layers near mid-ocean ridges. The median BML thickness in the Atlantic

Indian

and Pacific Oceans is 40 m

42 m

and 64 m

respectively

with a global median of 47 m. Finally

future research directions are proposed

emphasizing the need for advanced observational technologies such as deep-sea bottom-mooring systems and autonomous underwater vehicles

enhanced theoretical studies on the interactions between bottom shear flows

internal wave breaking

and topographic effects

and the development of high-resolution numerical simulation methods for the BML.
