Distribution of benthic foraminiferal taphocoenose in surface sediments and the environmental implication in the radial sand ridge of the South Yellow Sea

Abstract

Abstract:

We analyzed a total of 123 surface sediment samples obtained from the radial sand ridges (RSR) to uncover the relationships between the marine environmental parameters and foraminiferal assemblages. The results showed that the percentage of planktonic foraminifera was less than 7%, and its distribution was related to the offshore tide. The study area was dominated by foraminiferal species with high tolerance to shallow water and low salinity. Fifty-nine species with percentage contents ≥2% in more than three samples were chosen for the Q-mode factor analysis, from which three maximum variance (varimax) factors were obtained. By combining sediment particle size and modern marine environmental parameters, the study area was divided into three environmental zones: (1) The central RSR and large tidal inlet correspond to an Ammonia beccarii vars.-Nonion akitaense-Cribrononion frigidum assemblage. This area can be divided into two subregions: the northern RSR and large tidal inlet region representing the strong hydrodynamic nearshore sandy sedimentary environment affected by low-temperature coastal currents and tidal currents, and the southern study area including the Yangtze River Estuary reflecting the estuarine environment affected by strong oceanic tidal current. (2) The Haizhou Bay and the abandoned Yellow River Estuary region relate to the Ammonia compressiuscula-Spiroloculina laevigata-Elphidium advenum assemblage, representing a shallow sea environment (50 m) with silty sand and clay-based sediments. (3) The shallowest coastal areas of the southern RSR correspond to the Nonion anomalinoidea-Ammonia maruhasii-Ammonia pauciloculata assemblage, signifying the environment of nearshore shallow water, a low-salinity intertidal zone, or a subtidal zone with a silty and sandy bottom impacted by strong hydrodynamic force. In general, the distribution of benthic foraminiferal assemblages from the RSR is not only affected by temperature and salinity, but also related to the unique hydrodynamic condition, which is affected by offshore tidal current and inland rivers.

Key words: Southern Yellow Sea, radial sand ridge, surface sediment, benthic foraminifera, marine environment
