Jacques Whitford Environment Limited (now Stantec), on behalf of Encana Corporation, conducted a deep water benthic survey of former Exploration Licence 2414, referred to as Stonehouse. The survey was conducted on the 21 to 23 of August and 14 to 15 of September 2002. The Stonehouse area encompassed an area of 1,489 km2 and was located approximately 464 km from the port of Halifax, Nova Scotia. Water depths within the area ranged from approximately 500 to 3,200m.\n\nThis dataset contains species distribution records collected using 0.1 m2 Van Veen grab sampler. Additional information collected as part of the survey is available in the original report.

The objective was to determine the presence, distribution and diversity of the benthos and its ecological significance.\n\nOnly the grab sample information is provided in this dataset.","sampling":"Sediment grabs were collected using a 0.1 m2 Van Veen grab. Grab samples were subsampled and analyzed for biological, physical and chemical characteristics.\nA total of 17 grab samples were taken from within the Stonehouse area. \nOne 250 mL jar of sediment sample was removed from the upper 10 cm of each grab and analysed for grain size, metals, total inorganic carbon, total organic carbon, total petroleum hydrocarbons (C6-C32), benzene, toluene, ethylene and xylene. \nThe remaining sediment sample was sieved (500 um screen) onboard the R/V Anticosti by marine biologists and technicians.\nBiological contents were preserved in 90% denatured ethanol.\nOrganisms were later enumerated, weighed and identified to class, order or species level, where possible.","qualityControl":"Scientific names associated with resource occurrence records have been mapped to recognized standards - marine taxa have been mapped to the World Register of Marine Species (WoRMS).
