Tintinnid fingerprints in a plankton time series

Abstract

Tintinnid plankton in species-specific sensitivities to preferred hydrographic conditions has been monitored to link the temporal variations to climate change since 2008. Temporal changes of tintinnids were weekly investigated for 8 years at a coastal site in South Korea as part of an ongoing regional monitoring program. Seasonal changes of water temperature and salinity at the monitoring site displayed a typical pattern in the northern temperate coast: higher temperatures over 20℃ and salinity drop in summer. Recurrent seasonal patterns were observed for dominant species. Amphorellopsis acuta, Rhizodomus tagazi, Tintinnopsis beroidea, T. radix, T. tocantinensis were fingerprints for summer while T. baltica for winter. Codonellopsis nipponca and Schmidingerella arcuata occurred mainly in moderate seasons of spring and fall.t a coastal site in South Korea as part of an ongoing regional monitoring program.
