Infaunal invertebrates and contaminants in Saint John Harbour, New Brunswick, Canada

Drs. Heather Hunt (University of New Brunswick) and Karen Kidd (McMaster University) have been leading a long-term project sampling infaunal invertebrates, sediment contaminants, and sediment characteristics at subtidal sites in Saint John Harbour, NB, Canada. This multi-year project is establishing baseline data that can be used to assess cumulative environmental effects in Saint John Harbour.

Samples were collected yearly (2018-2020) in Fall (October or November) at 6 reference sites (3 in inner harbour and 3 in outer harbour) as well as at 5-7 potential hotspot sites. Samples were collected using a 0.1 m2 Smith McIntyre grab sampler. Infaunal invertebrates were counted from a portion of the grab with a surface area of 321 cm2 and identified to species. Concentrations of contaminants (22 metals and other elements; polycyclic aromatic hydrocarbons [4 sites in 2018 only]) were measured in surface sediment (upper 5 cm). Percent organic content (loss on ignition (LOI) at 550 and 950oC), total organic carbon (calculated from LOI), percent moisture, and % composition by grain size Wentworth size classes of the sediment were determined. See Van Geest et al. (2015) for detailed field and laboratory methods.

Fisheries and Oceans Canada and the Port of Saint John provided funding to collect this data. This project is part of the Coastal Environmental Baseline Program Initiative under the Oceans Protection Plan of Fisheries and Oceans Canada.

This multi-year project is establishing baseline data that can be used to assess cumulative environmental effects in Saint John Harbour. Samples were collected yearly (2018-2020) in Fall (October or November) at 6 reference sites (3 in inner harbour and 3 in outer harbour) as well as at 5-7 potential hotspot sites. Samples were collected using a 0.1 m2 Smith McIntyre grab sampler. Infaunal invertebrates were counted from a portion of the grab with a surface area of 321 cm2 and identified to species. Concentrations of contaminants (22 metals and other elements; polycyclic aromatic hydrocarbons [4 sites in 2018 only]) were measured in surface sediment (upper 5 cm). Percent organic content (loss on ignition (LOI) at 550 and 950oC), total organic carbon (calculated from LOI), percent moisture, and % composition by grain size Wentworth size classes of the sediment were determined. See Van Geest et al. (2015) for detailed field and laboratory methods. Fisheries and Oceans Canada and the Port of Saint John provided funding to collect this data.

Leur étude a observé des communautés d’invertébrés endo-benthiques et des contaminants, et a aussi effectué une caractérisation approfondie des sédiments sur les sites échantillonnés. Ce projet, mené sur plusieurs années, offre une base de données pouvant être utilisée pour l’évaluation des effets environnementaux cumulatifs dans le port de Saint John. Des échantillons ont été prélevés chaque année (2018-2020), en automne (octobre ou novembre), sur 6 sites de référence (3 situés à l’intérieur du port et 3 à l’extérieur) ainsi que sur 5 à 7 sites additionnels considérés comme potentiellement contaminés. Les carottes ont été prélevées à l’aide d’une benne Smith-McIntyre de 0.1 m2. L’abondance des invertébrés endo-benthiques (identifiés à l’espèce) a été mesurée sur une partie de la superficie totale de 321 cm2 échantillonnée. Les concentrations de contaminants (22 métaux et autres éléments; hydrocarbures aromatiques polycycliques [4 sites en 2018 seulement]) ont été mesurées dans les carottes prélevées jusqu’à une profondeur de 5 cm. Le pourcentage de teneur en matières organiques (pertes due au brûlage (LOI) à 550 et 950oC), le carbone organique total (calculé à partir du LOI), le pourcentage d’humidité et le type de sédiment (déterminé selon les classes de taille de la méthode de Wentworth) ont été mesurés pour tous les échantillons prélevés. Voir Van Geest et al. (2015) pour obtenir plus de détails sur les méthodes utilisées sur le terrain et en laboratoire. Pêches et Océans Canada et le port de Saint John ont fourni les fonds pour recueillir ces données. Ce projet fait partie du Programme sur les données environnementales côtières de référence de Pêches et Océan Canada.</lan:LocalisedCharacterString> </lan:textGroup> </lan:PT_FreeText> </mri:abstract> <mri:credit> <gco:CharacterString/> </mri:credit> <mri:status> <mcc:MD_ProgressCode codeList="http://standards.iso.org/iso/19115/resources/Codelists/cat/codelists.xml#MD_ProgressCode" codeListValue="onGoing"> </mcc:MD_ProgressCode> </mri:status> <mri:topicCategory> <mri:MD_TopicCategoryCode>oceans</mri:MD_TopicCategoryCode> </mri:topicCategory> <mri:extent> <gex:EX_Extent> <gex:geographicElement> <gex:EX_GeographicBoundingBox> <gex:extentTypeCode> <gco:Boolean>true</gco:Boolean> </gex:extentTypeCode> <gex:westBoundLongitude> <gco:Decimal>-66.099</gco:Decimal> </gex:westBoundLongitude> <gex:eastBoundLongitude> <gco:Decimal>-65.9685</gco:Decimal> </gex:eastBoundLongitude> <gex:southBoundLatitude> <gco:Decimal>45.20167</gco:Decimal> </gex:southBoundLatitude> <gex:northBoundLatitude> <gco:Decimal>45.2738</gco:Decimal> </gex:northBoundLatitude> </gex:EX_GeographicBoundingBox> </gex:geographicElement> </gex:EX_Extent> </mri:extent> <mri:extent> <gex:EX_Extent> <gex:verticalElement> <gex:EX_VerticalExtent> <gex:minimumValue> <gco:Real>0.0</gco:Real> </gex:minimumValue> <gex:maximumValue> <gco:Real>9.0</gco:Real> </gex:maximumValue> <gex:verticalCRSId> <mrs:MD_ReferenceSystem> <mrs:referenceSystemIdentifier> <mcc:MD_Identifier> <mcc:code> <gco:CharacterString>5831</gco:CharacterString> </mcc:code> <mcc:codeSpace> <gco:CharacterString>EPSG</gco:CharacterString> </mcc:codeSpace> <mcc:version> <gco:CharacterString>2012-08-10</gco:CharacterString> </mcc:version> <mcc:description> <gco:CharacterString>EPSG::5831 - Instantaneous Water Level depth - Depth relative to instantaneous water level uncorrected for tide.
