Description:This dataset consists of monthly mean simulation results from Canada's three Oceans: the Atlantic, Pacific and Arctic from 2015 to 2017.Abstract from the report:A numerical ocean model with biogeochemistry has been developed for a domain that spans Canada's three oceans: the Atlantic, Pacific and Arctic. The domain extends to 26°N in the Atlantic and 44°N in the Pacific, and spans the full width of each basin as well as the whole of the Arctic Ocean. The resolution is moderate to high (≈0.25°, 75 levels). A series of simulations was conducted to assess the best choices for biogeochemical model parameters across the diverse regions, using a variety of validation data sets including satellite ocean colour (surface chlorophyll and particulate organic carbon, integrated primary production), surface underway pCO2, and depth profiles of oxygen and nitrate concentration from ships and Argo floats. In addition to parameter values, processes examined include interactive sediments, fluvial nutrients, light attenuation by fluvial coloured dissolved organic matter (CDOM), and iron limitation. The results indicate that the optimal parameter set is one that limits phytoplankton losses to grazing and other processes so as to ensure strong biological drawdown of dissolved inorganic carbon and nutrients in spring and summer; among the parameter sets tested both insufficient and excessive drawdown were observed. Sensitivity to other processes such as interactive sediments, fluvial nutrients or CDOM attenuation was weak in most regions. In some regions, attenuation by CDOM or sequestration of nutrients in the sediment can substantially reduce primary production and zooplankton biomass, and fluvial nutrients can cause localized reduction of pCO2 by as much as 60 μatm. Iron limitation has an effect on the model solution in regions generally considered iron-replete; building a model that successfully spans iron-limited and non-iron-limited domains will require complete and accurate specification of iron sources and sinks.

The Base Features Access and Facility Roads spatial layer is the authoritative source of road data for the province of Alberta. It is a part of the Access data collection which also includes railways, powerlines, cutlines and trails, and industrial facilities.

Geometric and conventional representation of the rail system for planning purposes.This geospatial data is structured according to the following layers of information;- CARTO-IR-ACCESSORY: level crossing barrier & level pass lantern- CARTO-FER-DEBARCADERE: dock for the embarkation/disembarkation of goods or passengers- CARTO-FER-PONT: railway engineering structure making it possible to cross an obstacle- CARTO-FER-VOIE: railwayThese elements form part of the layers in the digital cartographic compilation.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

The Base Features Access Railway spatial layer is the authoritative source of railway data for the province of Alberta. It is a part of the Access data collection which also includes roads, powerlines, cutlines and trails, and industrial facilities.

RAILLINE_OFFICIAL is one of the important layers for Saskatchewan Upgraded Road Network (SURN) and National Road Network (NRN). The RAILLINE_OFFICIAL provides the information of Railine to clients that require accurate, relatively up-to-date and detailed description of Saskatchewan Railline Network.RAILLINE_OFFICIAL data layer was developed by the Saskatchewan Ministry of Highways & infrastructure and contains the OFFICIAL version of the rail lines network in the province. RAILLINE_OFFICIAL layer has the linear geomtry of the CN, CP and provincial/shortline rail line in Saskatchewan. This version of the network is the one used for mapping, querying and plotting.

The Base Features Access Powerline spatial layer is the authoritative source of powerline data for the province of Alberta. It is a part of the Access data collection which also includes railways, roads, cutlines and trails, and industrial facilities.

The purpose of this dataset is to depict the boundaries of the Niagara Escarpment Plan. The outer boundary of the area covered by the Niagara Escarpment Plan is fixed and inflexible. It can only be changed by a plan amendment. It is formed by a combination of features like: * roads * railways * electrical transmission lines * municipal and property boundaries * lot lines * rivers * other topographic features [More information](http://www.escarpment.org)
