Canada1Water Classification of the National Hydro Network: Stream Order and Graph Refinement
A vector representation of stream networks is a crucial dataset for the modelling the surface water and groundwater components of the hydrologic cycle. For many usages a crucial attribute of the drainage network is a digital topology and hierarchal stream order attribute (e.g., Strahler stream order). In Canada jurisdictional stream networks are available for the provinces and territories and nationally for Canada in the National Hydrological Network (NHN) dataset. Unfortunately, the NHN data lacks the same topological and attribute information that is available for numerous provinces due to standardization for the entire country. For Canada1Water it was also necessary to have a harmonized dataset with the United States, for both the southern transboundary watersheds and the Alaskan watersheds. This report documents the processes completed to upgrade the topological and graph network support for NHN and provide continuous connectivity with US datasets. It also highlights and corrects a number of stream density and stream order issues that occur within Canada across provincial and territorial borders and NTS tiles. All vector processing was completed in RivEX software extension for ArcMap. Following complete topological correction stream classification was assigned and a table of the node graph network developed. Additional work was then completed to normalize stream density particularly amongst low-order streams between British Columbia and the Yukon and amongst local NTS tiles in Quebec and Ontario. Corrected NHN Strahler stream order assignment was validated against a number of provincial and watershed datasets, all of which already have Strahler stream order attributed. These datasets are the same underlying digitized vector data, so there are no differences in node or polyline positions. Strahler stream order assignment validation was only done by visual comparison as due to differences in vector segments a statistical comparison is complicated. The transboundary integrated C1W stream network with complete classification provides a seamless national dataset to support transdisciplinary studies (fisheries, wildlife, health, pesticide and nutrient issues, mining impact, ecosystem restoration, numeric modelling) that involve a knowledge of stream distribution and ranking.

Habitat associations of juvenile American lobster in three nearshore areas of Newfoundland
This project was completed by the Productive Capacity group (Coastal and Freshwater Ecology Section) in the Newfoundland and Labrador Science Branch of Fisheries and Oceans Canada (DFO). American lobster (Homarus americanus) is a commercially important decapod crustacean species along the east coast of North America, ranging from the Labrador coast south to Cape Hatteras. Juvenile lobster < 40 mm CL (carapace length) recruitment has been studied extensively in the southern portions of their range. However, investigations of settlement habitat association and recruitment of juvenile lobster in the northern extremes along the Newfoundland coast have been largely unsuccessful. We investigated juvenile lobster density, habitat, and depth associations in three areas of Newfoundland, using scuba – Port Saunders area, 8 dives conducted 28 September - 2 October 2017, and Burin Peninsula 10 dives (7 Placentia Bay, 3 Fortune Bay) conducted 30 September - 4 October 2018 over a total seabed area of 9,138 m2, within 200 meters of shore. Port Saunders and Fortune Bay had relatively higher lobster density (0.09 and 0.40 m-2, respectively); >65% were juveniles, in contrast to Placentia Bay where lobster densities of all size groups were low (mean 0.01 m-2) and no juvenile lobsters were observed at all. Where observed all juvenile lobster were significantly associated with shallow (<6 m) habitat and showed no overlap with distribution of adults (>82.5 mm CL) which we observed at depths 6 to 17 m. Our sites were dominated by varying mixes of cobble and pebble (77%); rock/bedrock (12%) and mud/sand/small pebble (11%) substrates interspersed with overlying kelp (32%) and eelgrass (11%) vegetation. We observed no significant associations with substrate or vegetation. This record contains the geographic locations of the 7 Placentia Bay sites surveyed, and information on the timing and type of data collected at each site, which was one component supported by Coastal Environmental Baseline Program of a larger collaborative project.

BLKPASSAGE OFFICIAL
BLKPASSAGE_OFFICIAL is one of the important layers for Saskatchewan Upgraded Road Network (SURN) and National Road Network (NRN). The BLKPASSAGE_OFFICIAL provides the information of road blocked passage to clients that require accurate, relatively up-to-date and detailed description of Saskatchewan Road Network.BLKPASSAGE_OFFICIAL, This layer contains data for a structure indicating a physical barrier on a Road Element built to prevent or control further access. BLKPASSAGE_OFFICIAL contains all the blocked passage points in the Saskatchewan. BLKPASSAGE_OFFICIAL is an important part of the Saskatchewan road network dataset. Each point geometry " BLKPASSAGE" has unique Identifiers (NID). "NID" National Identifier is used to manage the updates between data producer and data users.
ROADSEG
ROADSEG is one of the important layers for Saskatchewan Upgraded Road Network (SURN) and National Road Network (NRN). The ROADSEG is created to serve a diverse group of clients that require relatively up-to-date and accurate description of Saskatchewan Road Network.ROADSEG contains all the features from HIGHWAY_OFFICIAL, RURAL_ROAD_OFFICIAL and OTHER_ROAD_OFFICIAL. ROADSEG is the Saskatchewan road network data that is being used by NRCAN as National Road Network (NRN). ROADSED data layer has been generated by merging HIGHWAY_OFFICIAL, RURAL_ROAD_OFFICIAL and OTHER_ROAD_OFFICIAL. Unique Identifiers (NID) is associated with each line segment. "NID" National Identifier is used to manage the updates between data producer and data users. ROADSEG data layer is one of the important data table for SURN, NRN, SASK911, CAR, SGI-iHaul and other applications.
