This program ran between 2006-2011. The CAISN II project (2011-2016) was designed to provide a comprehensive profile of AIS in waters across Canada and develop and determine effectiveness of tools for early detection of, and rapid response to invaders.\n\nThis resource contains the information on a CAISN II baseline study for benthic invertebrates in search of non-indigenous species (NIS) from the Canadian Arctic coasts made during summers 2011-2012. This survey identified as well native species by incorporating historical information to identify new records. The top three ports at highest risk for introduction of NIS of the Canadian Arctic were surveyed: Churchill (Manitoba), Deception Bay (Quebec) and Iqaluit (Nunavut). It also includes information on Steesnby Inlet (Nunavut) that was sampled given that it is a proposed site for the construction of a new port. A total of 287 genera and species were identified. \n\nIncreased survey effort is the most likely explanation for the majority of new occurrences, however, a small number of records (n&#61;7) were new mentions for Canada and were categorized as cryptogenic since we could not confidently describe them as being either native or introduced. Further research is required to better understand the status of these new taxa. \n\nThis dataset formed the basis of a PhD thesis (Goldsmit, Jesica 2016).</p>","language":"eng","homepage":"http://iobis.org/mapper/?resource_id=xx","citation":{"text":"Goldsmit J (2017).

These ports are considered to be at highest risk for the introduction of NIS based on the number of vessel arrivals and ballast discharge for all vessel categories between years 2005–2008 (Chan et al. 2012, 2013). \nThe location of Steensby Inlet was also sampled given that it is the proposed site for a future port that will be constructed related to an iron exploitation mine project.","sampling":"Two ports were sampled in 2011 (Iqaluit and Churchill) and two in 2012 (Deception Bay and Steensby Inlet). Surveys for benthic samples were conducted following design: 5 zones per port, 4 elevations per zone (2 intertidal, 2 subtidal), 4 random replicate samples per elevation. The port area and its surroundings, including both marine and estuarine habitats, were sampled. The sampled elevations included two intertidal (high and low elevation) and two subtidal (shallow: 0–10 m, and deep: 10–20 m; at low tide). Random replicate samples were collected at each zone-elevation location using a 15 cm high x 10 cm diameter core and sieved to a minimum of 500 μm. All samples were preserved in 4% buffered formalin.\n\nFor further information see Goldsmit et al (2014) in Aquatic Invasions Journal.","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).
