Utilizing Benthic Video Footage for Detecting Large Debris on the Seafloor in Placentia Bay, Newfoundland (2019)

This data was collected in 2019 at three locations in Placentia Bay by another research group at Memorial University, as a part of the Coastal Environmental Baseline Program Initiative under the Oceans Protection Plan of Fisheries and Oceans Canada (DFO).

Video footage from drop cameras used for ground truthing was shared with the Placentia Bay Ocean Debris Survey for the purpose of analyzing for macro-debris present on the seafloor. Average field of view (FOV) was estimated for each individual video and GPS coordinates were used to estimate video transect lengths in order to determine debris density. When identified, debris was categorized according to its size, material, source category, and interaction with surround environment.

Des séquences vidéo des caméras de largage utilisées pour la vérification au sol ont été partagées avec le *Placentia Bay Ocean Debris Survey* (PODS) dans le but d&#39;analyser les macro-débris présents sur le fond marin. Le champ de vision moyen (FOV) a été estimé pour chaque vidéo individuelle et les coordonnées GPS ont été utilisées pour estimer la longueur des transects vidéo afin de déterminer la densité des débris. Une fois identifiés, les débris ont été classés en fonction de leur taille, matériau, catégorie de source et interaction avec l&#39;environnement ambiant.</lan:LocalisedCharacterString> </lan:textGroup> </lan:PT_FreeText> </mri:abstract> <mri:credit> <gco:CharacterString></gco:CharacterString> </mri:credit> <mri:status> <mcc:MD_ProgressCode codeList="http://standards.iso.org/iso/19115/resources/Codelists/cat/codelists.xml#MD_ProgressCode" codeListValue="completed"></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_BoundingPolygon> <gex:extentTypeCode> <gco:Boolean>true</gco:Boolean> </gex:extentTypeCode> <gex:polygon> <gml:Polygon gml:id="a1"> <gml:exterior> <gml:LinearRing> <gml:coordinates>-55.241367526148,47.13318059533826 -54.03287145150085,46.75252399555157 -53.76095983495322,47.479584530843795 -54.04111119745684,47.89558933645629 -55.241367526148,47.13318059533826</gml:coordinates> </gml:LinearRing> </gml:exterior> </gml:Polygon> </gex:polygon> </gex:EX_BoundingPolygon> </gex:geographicElement> </gex:EX_Extent> </mri:extent> <mri:extent> <gex:EX_Extent> <gex:verticalElement> <gex:EX_VerticalExtent> <gex:minimumValue> <gco:Real>8.4</gco:Real> </gex:minimumValue> <gex:maximumValue> <gco:Real>98.1</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.
