Significance of planktonic ciliated protozoa in the Lower St. Lawrence Estuary: comparison with bacterial, phytoplankton, and particulate organic carbon

Relationships between bacteria, phytoplankton and particulate organic carbon in the Upper St. Lawrence Estuary

The relationships between bacterial and phytoplankton variables, and particulate organlc carbon (POC), were examined along a longitudinal transect in the St. Lawrence Estuary Free bacteria, bacterial biomass and heterotrophic activity decreased in a seaward direction, whereas chlorophyll, phytoplankton biomass and photosynthetic act~vity had minimum values in the mid-estuanne region Values of P...

Reproduction of the planktonic copepod Calan us finmarchicus in the Lower St. Lawrence Estuary: relation to the cycle of phytoplankton production and evidence for a Calanus pump

Due to the dynamic physical environment of the Lower St. Lawrence Estuary, the spring phytoplankton bloom in the Laurentian Channel occurs late in the season, typically in mid-June, but the high phytoplankton biomass is sustained throughout the summer months. In this study, relationships between the phytoplankton production cycle, water temperature, and the reproductive cycle of Calanus finmarc...

Organic matter reactivity indicators in sediments of the St . Lawrence Estuary

Here we report multiple parameters used to describe the diagenetic state of sediments, including total hydrolysable amino acid (THAA), amino acid enantiomer, chlorin (CI) and amino acid degradation (DI, RI) indices, along a transect between the Upper St. Lawrence Estuary and the Gulf of St. Lawrence, Canada. The study area is characterized by gradients in water oxygen concentration, water depth...
