SUMMER 2019
KANGIQSUALUJJUAQ
Kangiqsualujjuaq is an Inuit village located at the mouth of the George River on the east coast of Ungava Bay in Nunavik, Quebec, Canada. We have sampled water and sediments from the water intake of the village (lake), raw and treated water from the drinking water treatment plant and water from the alternative drinking water source of the village (small stream).
WINTER 2018
SAINT-CHARLES RIVER
Water and sediment samples were collected in the Saint-Charles River (Quebec, Canada) during the winter 2018 between the Saint-Charles Lake and the Loretteville Drinking Water Treatment Plant (11 km downstream of the lake, 11 sampling points). This sampling aimed to complete our winter sampling to deeply investigate microbial communities in a ice-covered river.
SUMMER 2017
SAINT-CHARLES RIVER
The Saint-Charles River, an important drinking water source for Quebec city, Canada, is evenly fed by the Saint-Charles Lake and two main tributaries (Jaune and Nelson Rivers). Water samples were collected in October 2017 in the Saint-Charles River between the Saint-Charles Lake and the Loretteville Drinking Water Treatment Plant (11 km downstream of the lake) and in the main tributaries (25 sampling points). This sampling aimed to monitored the changes in the community structure of bacteria and microbial eukaryotes along the river to better understand impact of river conditions and input of tributaries on the aquatic microbial communities.

WACS
The oceanographic cruise WACS (West Africa Cold seeps) took place on board the Pourquoi Pas? research vessel from January 27, 2011 to February 28, 2011 in the Guinean Gulf. The main objective of the WACS cruise was to study the diversity and the overall functioning of the cold seep ecosystems located in this Gulf [web-link].
2016-2017-2018
SAINT-CHARLES RIVER
The Saint-Charles River is a major drinking water source in the Quebec city region (Canada). Water samples were collected weekly or bimonthly at the raw water intake of the Loretteville Drinking Water Treatment Plant from May 2016 to June 2017 with two additional sampling during the winter 2018, representing a total of 34 sampling dates. This sampling aimed to monitored the seasonal changes in the community structure of bacteria and pico- and nanoplanktonic protists (i.e. small microbial eukaryotes of 0.22 - 20 µm diameter).
DECEMBER 2011
CONGOLOBE
The oceanographis cruise Congolobe took place on board the Pourquoi Pas? research vessel. The main objective of the Congolobe cruise was to study the active region of the Congo deep-sea fan, called the terminal lobes or lobe complex at 4700-5100 m water depth and 750-800 km offshore. It is a unique sedimentary area fed by a submarine canyon and a channel-levee system which presently deliver large amounts of organic carbon originating from the Congo River by turbidity currents [web-link, publication]
