The temporal dynamics of meroplankton, manly comprised of larvae of benthic invertebrates that only temporarily inhabit the pelagic environment, is poorly understood in Arctic environments. The main objective of this thesis was to increase our knowledge on meroplankton dynamics and their ecological role in the Arctic marine coastal ecosystem. Three different approaches including high-frequency field sampling, molecular identification (DNA bar-coding, Bivalvia) and feeding experiments (Cirripedia nauplii) were applied to investigate the highly dynamic nature of meroplankton and how they relate to biological and environmental drivers and what might be their potential feeding impact during mass occurrences. Meroplankton contributed considerably to the total zooplankton abundance during the productive time of the year. A strong correlation of total meroplankton abundance with phytoplankton biomass was observed as a general pattern. We found that the timing of the spring bloom determined the onset of the “meroplankton-boost”, which mainly comprised Cirripedia and Bivalvia larvae. Strong seasonality was also found in the occurrence of the different bivalve larval species. The feeding experiments gave limited results, since the experimental set-up needs some improvements. Our investigation suggests that benthic invertebrate larvae play a significant role in the pelagic ecosystems in Arctic coastal regions, linking the pelagic and benthic realms. The different reproductive strategies of benthic invertebrates with planktonic larvae are discussed and some speculations about potential changes in a warming Arctic climate are made.
