Ces données peuvent être utilisées comme source de références pour la surveillance d'introduction d'espèces potentiellement non-indigènes introduites dans les ports arctiques où les activités maritimes sont élevées.\n\n\n**ÉCHANTILLONNAGE**\n\n\nDes échantillons de dinoflagellés ont été prélevés à l'aide d'un filet à plancton Nitex® de mailles 20 μm (30 cm de diamètre) pendant le mois d'août à Churchill (MB) en 2007 et 2015, à Deception Bay (QC) en 2016, à Iqaluit (NU) en 2015 et 2019 et à Milne Inlet en 2017. Les échantillons ont été récoltés à partir de 1 m de la surface jusqu’à 1 m au-dessus du fond.\n\n\n*PRÉPARATION :* Les échantillons ont été conservés dans du formaldéhyde à 4%. La préparation et le comptage des échantillons ont été réalisés à l’aide de la méthode Utermöhl.\n\n\n*OBSERVATION :* L'observation des échantillons s'est faite à l'aide d’un microscope inversé de la marque « NIKON Eclipse TE-2000-U », sous un grossissement de 200x.\n\n\n*ABONDANCE :* Le calcul de l’abondance des dinoflagellés (cellule/litre) s'est effectué comme suit : Nombre de cellules X Volume de la bouteille/Volume de la chambre Utermöhl/ (pi X Rayon^2 X Profondeur) X 1000\n\n\n**VARIABLES ENVIRONNEMENTALES**\n\n\nLes données environnementales ont été mesurées à l'aide d'un CTD et d'un disque de Secchi. Le temps entre la fonte des glaces de mer et l'échantillonnage a été calculé en soustrayant le jour d'échantillonnage aux dates de débâcle (concentration de glace <1/10) qui ont été extraites des archives du Service canadien des glaces.\n\n\nPour information supplémentaire, veuillez consulter l’article suivant : Dhifallah F, Rochon A, Simard N, McKindsey CW, Gosselin M, Howland KL. 2022.

These data can be used as a reference source for monitoring the introduction of potentially non-native species introduced into Arctic ports where shipping activities are high.\n\n\n**SAMPLING**\n\n\nDinoflagellate samples were collected using a 20 μm (30 cm diameter) Nitex® plankton net during August in Churchill (MB) (2007 and 2015), in Deception Bay (QC ) (2016), in Iqaluit (NU) (2015 and 2019) and in Milne Inlet (2017). Samples were collected from 1 m of the surface to 1 m above the bottom.\n\n\n*PREPARATION :* Samples were stored in 4% formaldehyde. Sample preparation and counting were performed using the Utermöhl method.\n\n\n*OBSERVATION :* Samples were observed using an inverted microscope (NIKON Eclipse TE-2000-U) under a magnification of 200x.\n\n\n*ABUNDANCE :* The calculation of the abundance of dinoflagellates (cell / liter) was carried out as follows: Number of cells X Volume of the bottle / Volume of the Utermöhl chamber / (pi X Radius^2 X Depth) X 1000\n\n\n** ENVIRONMENTAL VARIABLES **\n\n\nEnvironmental data were measured using a CTD and a Secchi disk. The time between sea ice melt and sampling was calculated by subtracting the sampling day from the breakup dates (ice concentration <1/10) which were extracted from the Canadian Ice Service records.\n\n\nFor further information, please consult the following paper: Dhifallah F, Rochon A, Simard N, McKindsey CW, Gosselin M, Howland KL. 2022.

Ces données peuvent être utilisées comme source de références pour la surveillance d'introduction d'espèces potentiellement non-indigènes introduites dans les ports arctiques où les activités maritimes sont élevées.\n\n\n**ÉCHANTILLONNAGE**\n\n\nDes échantillons de dinoflagellés ont été prélevés à l'aide d'un filet à plancton Nitex® de mailles 20 μm (30 cm de diamètre) pendant le mois d'août à Churchill (MB) en 2007 et 2015, à Deception Bay (QC) en 2016, à Iqaluit (NU) en 2015 et 2019 et à Milne Inlet en 2017. Les échantillons ont été récoltés à partir de 1 m de la surface jusqu’à 1 m au-dessus du fond.\n\n\n*PRÉPARATION :* Les échantillons ont été conservés dans du formaldéhyde à 4%. La préparation et le comptage des échantillons ont été réalisés à l’aide de la méthode Utermöhl.\n\n\n*OBSERVATION :* L'observation des échantillons s'est faite à l'aide d’un microscope inversé de la marque « NIKON Eclipse TE-2000-U », sous un grossissement de 200x.\n\n\n*ABONDANCE :* Le calcul de l’abondance des dinoflagellés (cellule/litre) s'est effectué comme suit : Nombre de cellules X Volume de la bouteille/Volume de la chambre Utermöhl/ (pi X Rayon^2 X Profondeur) X 1000\n\n\n**VARIABLES ENVIRONNEMENTALES**\n\n\nLes données environnementales ont été mesurées à l'aide d'un CTD et d'un disque de Secchi. Le temps entre la fonte des glaces de mer et l'échantillonnage a été calculé en soustrayant le jour d'échantillonnage aux dates de débâcle (concentration de glace <1/10) qui ont été extraites des archives du Service canadien des glaces.\n\n\nPour information supplémentaire, veuillez consulter l’article suivant : Dhifallah F, Rochon A, Simard N, McKindsey CW, Gosselin M, Howland KL. 2022.

preparing for increased shipping related to resource development and climate change; \n\n- Diversity of pelagic primary producers in coastal habitats and the potential for harmful blooms in Eastern Canadian Arctic, with a focus near Iqaluit, Nunavut. \n\n\nThese data are the abundance, richness and diversity of dinoflagellate communities in Canadian Arctic seaports to provide baseline data and to verify the presence of potential non-indigenous species and harmful taxa. These data can be used as a reference source for monitoring the introduction of potentially non-native species introduced into Arctic ports where shipping activities are high.\n\n\n**SAMPLING**\n\n\nDinoflagellate samples were collected using a 20 μm (30 cm diameter) Nitex® plankton net during August in Churchill (MB) (2007 and 2015), in Deception Bay (QC ) (2016), in Iqaluit (NU) (2015 and 2019) and in Milne Inlet (2017). Samples were collected from 1 m of the surface to 1 m above the bottom.\n\n\n*PREPARATION :* Samples were stored in 4% formaldehyde. Sample preparation and counting were performed using the Utermöhl method.\n\n\n*OBSERVATION :* Samples were observed using an inverted microscope (NIKON Eclipse TE-2000-U) under a magnification of 200x.\n\n\n*ABUNDANCE :* The calculation of the abundance of dinoflagellates (cell / liter) was carried out as follows: Number of cells X Volume of the bottle / Volume of the Utermöhl chamber / (pi X Radius^2 X Depth) X 1000\n\n\n** ENVIRONMENTAL VARIABLES **\n\n\nEnvironmental data were measured using a CTD and a Secchi disk. The time between sea ice melt and sampling was calculated by subtracting the sampling day from the breakup dates (ice concentration <1/10) which were extracted from the Canadian Ice Service records.\n\n\nFor further information, please consult the following paper: Dhifallah F, Rochon A, Simard N, McKindsey CW, Gosselin M, Howland KL. 2022. Dinoflagellate communities in high-risk Canadian Arctic ports. Estuarine, Coastal and Shelf Science 266:107731\n\n\nThis project is part of the Coastal Environmental Baseline Program Initiative under the Oceans Protection Plan of Fisheries and Oceans Canada.\n \n \n Les données ont été échantillonnées au cours de deux projets :\n\n\n- Développement d'une surveillance des espèces aquatiques envahissantes dans l'Arctique canadien - préparation à l'augmentation du trafic maritime lié au développement des ressources et aux changements climatiques; \n\n- Diversité des producteurs primaires dans les milieux côtiers et possibilité d'efflorescences nuisibles dans l'est de l'Arctique canadien, en particulier près d'Iqaluit au Nunavut. \n\n\nCes données sont l'abondance, la richesse et la diversité des communautés de dinoflagellés dans les ports maritimes de l'Arctique canadien afin de fournir des données de références et de vérifier la présence d'espèces potentiellement non-indigènes et nuisibles. Ces données peuvent être utilisées comme source de références pour la surveillance d'introduction d'espèces potentiellement non-indigènes introduites dans les ports arctiques où les activités maritimes sont élevées.\n\n\n**ÉCHANTILLONNAGE**\n\n\nDes échantillons de dinoflagellés ont été prélevés à l'aide d'un filet à plancton Nitex® de mailles 20 μm (30 cm de diamètre) pendant le mois d'août à Churchill (MB) en 2007 et 2015, à Deception Bay (QC) en 2016, à Iqaluit (NU) en 2015 et 2019 et à Milne Inlet en 2017. Les échantillons ont été récoltés à partir de 1 m de la surface jusqu’à 1 m au-dessus du fond.\n\n\n*PRÉPARATION :* Les échantillons ont été conservés dans du formaldéhyde à 4%. La préparation et le comptage des échantillons ont été réalisés à l’aide de la méthode Utermöhl.\n\n\n*OBSERVATION :* L'observation des échantillons s'est faite à l'aide d’un microscope inversé de la marque « NIKON Eclipse TE-2000-U », sous un grossissement de 200x.\n\n\n*ABONDANCE :* Le calcul de l’abondance des dinoflagellés (cellule/litre) s'est effectué comme suit : Nombre de cellules X Volume de la bouteille/Volume de la chambre Utermöhl/ (pi X Rayon^2 X Profondeur) X 1000\n\n\n**VARIABLES ENVIRONNEMENTALES**\n\n\nLes données environnementales ont été mesurées à l'aide d'un CTD et d'un disque de Secchi. Le temps entre la fonte des glaces de mer et l'échantillonnage a été calculé en soustrayant le jour d'échantillonnage aux dates de débâcle (concentration de glace <1/10) qui ont été extraites des archives du Service canadien des glaces.\n\n\nPour information supplémentaire, veuillez consulter l’article suivant : Dhifallah F, Rochon A, Simard N, McKindsey CW, Gosselin M, Howland KL. 2022.
