Abstract

The Strait of Malacca is well-known as an important trade route with high marine biodiversity. Among the organisms residing in the strait are the reef-building hard corals. Studies have shown that climate change and other anthropogenic stressors have induced severe degradation of coral reefs through the disruption of coral productivity and metabolisms. Moreover, in-depth investigations of causal inference of coral degradation and its correlations with potential coral-affecting physicochemical factors within the strait are limited. Hence, this study presents the analyses of the latest bi-decadal time-series trend from 1995 to 2016 of the live hard coral coverage (or live coral cover) and six coral-affecting physicochemical factors (significant wave height, sea surface salinity, particulate inorganic carbon, particulate organic carbon, turbidity, and sea surface temperature) using remote sensing and reanalysis datasets. Their potential correlations were interpreted by implementing meta- and statistical analyses of past coral surveys and remote sensing data. This study revealed the overall persistent bi-decadal decline in live hard coral coverage within the Strait of Malacca and the complex correlations among the factors that correspond to the spatial stratification of the marine environment. Among the six physicochemical factors, sea surface temperature, turbidity, and sea surface salinity were determined to be the most influential parameters on live coral cover distribution within the strait.

1995 至 2016 年马六甲海峡活硬珊瑚覆盖层分布及其理化因子评估。

众所周知，马六甲海峡是一条重要的贸易通道，具有高度的海洋生物多样性。栖息在海峡中的生物包括造礁硬珊瑚。研究表明，气候变化和其他人为压力因素破坏了珊瑚的生产力和新陈代谢，导致珊瑚礁严重退化。此外，对海峡内珊瑚礁退化的因果推断及其与潜在影响珊瑚礁的物理化学因素的相关性的深入研究还很有限。因此，本研究利用遥感和再分析数据集，分析了 1995 年至 2016 年活硬珊瑚覆盖率（或活珊瑚覆盖率）和六个影响珊瑚的理化因子（显著波高、海面盐度、颗粒无机碳、颗粒有机碳、浊度和海面温度）的最新双十年时间序列趋势。通过对过去的珊瑚调查和遥感数据进行元分析和统计分析，对其潜在的相关性进行了解释。这项研究揭示了马六甲海峡内活硬珊瑚覆盖率每十年持续下降的总体情况，以及与海洋环境空间分层相对应的各因素之间的复杂相关性。在六个物理化学因素中，海面温度、浊度和海面盐度被确定为对海峡内活珊瑚覆盖率分布影响最大的参数。

期刊介绍： Marine Environmental Research publishes original research papers on chemical, physical, and biological interactions in the oceans and coastal waters. The journal serves as a forum for new information on biology, chemistry, and toxicology and syntheses that advance understanding of marine environmental processes. Submission of multidisciplinary studies is encouraged. Studies that utilize experimental approaches to clarify the roles of anthropogenic and natural causes of changes in marine ecosystems are especially welcome, as are those studies that represent new developments of a theoretical or conceptual aspect of marine science. All papers published in this journal are reviewed by qualified peers prior to acceptance and publication. Examples of topics considered to be appropriate for the journal include, but are not limited to, the following: – The extent, persistence, and consequences of change and the recovery from such change in natural marine systems – The biochemical, physiological, and ecological consequences of contaminants to marine organisms and ecosystems – The biogeochemistry of naturally occurring and anthropogenic substances – Models that describe and predict the above processes – Monitoring studies, to the extent that their results provide new information on functional processes – Methodological papers describing improved quantitative techniques for the marine sciences.
