The climatologies presented here are based on information from thousands of temperature and precipitation observation sites in British Columbia, Yukon, Alberta, Alaska, Washington, Idaho, and Montana. The temperature climatologies were supplemented by upper atmosphere temperature climatologies derived from the National Center for Environmental Prediction’s North American Regional Reanalysis (Mesinger et al., 2006; emc.ncep.noaa.gov/mmb/rreanl/ ). Precipitation climatologies were improved using data from snow observing networks in British Columbia (link is external) and the United States. Further information about high-elevation precipitation was obtained by analyzing the glacier inventory for British Columbia developed by the University of Northern British Columbia (Bolch et al., 2010). A subsequent report will detail the creation of these climatologies and explain how these data were applied.
The simulated data includes snow water equivalent, soil moisture, surface runoff (runoff), subsurface runoff (baseflow), and actual evapotranspiration for a region covering the Peace, upper Columbia, Fraser and Campbell River watersheds. Daily values are provided for all variables, with projected data available from 1950-01-01 to 2100-12-31 and historical data available from 1950-01-01 to 2006-12-3. For the hydrologic projections, the GCM data were downscaled to a 1/16-degree resolution using Bias-Correction Spatial Disaggregation (BCSD) (Wood et al. 2004) following Werner (2011). Application of the VIC model and the generation of hydrologic projections for the Peace, Fraser, upper Columbia and Campbell River watersheds are described in Shrestha et al. (2012) and Schnorbus et al. (2011, 2014). The gridded data were simulated using the Variable Infiltration Capacity (VIC) model (Liang et al. 1994, 1996). The simulations are generated by forcing the VIC model using statistically downscaled global climate model (GCM) projections from the Coupled Model Intercomparison Project Phase 3 (CMIP3; Meehl et al. 2007) driven by a range of future emission specified by three separate scenarios (A1B, A2 and B1) from the IPCC Special Report on Emissions Scenarios (SRES; Nakicenovic et al. 2000). Also included is historical data generated by running the VIC model with interpolated observed climate data.
SPLASH (Structure of Populations, Levels of Abundance and Status of Humpbacks) represents one of the largest international collaborative studies of any whale population ever conducted. It was designed to determine the abundance, trends, movements, and population structure of humpback whales throughout the North Pacific and to examine human impacts on this population. This study involved over 50 research groups and more than 400 researchers in 10 countries. It was supported by a number of agencies and organizations including the National Marine Fisheries Service, the National Marine Sanctuary Program, National Fish and Wildlife Foundation, Pacific Life Foundation, Department of Fisheries and Oceans Canada, and Commission for Environmental Cooperation with additional support from a number of other organizations and governments for effort in specific regions. Results presented here include a comprehensive analysis of individual identification photographs. Additional analysis of human impacts, ecosystem markers (e.g., stable isotopes) and the genetic structure of populations are underway or planned pending further funding.
The dataset contains river current measurements by an Acoustic Scintillation Flowmeter (ASFM) at one level (1991 and 1993) or two levels (1995, 1996, 1997 and 1998) below lowest normal tide. The receiving system was located next to the Annacis Island dock for the large car freighters, and the transmitting system was at the South Surrey docks approximately 500 metres away. The measurement levels were fixed, and so the depth below the river surface varied with the state of the tide. When opertional, currents were measured approximately every 2.5 minutes. The currents reprent a true average of the current across the 500m path. The data file does not necessarily contain full months of data and some months of data may be missing. Some down time occurred due to some operational problems such as site damaged by ships or log booms. There was also be interference from passing ships. If a measurement exists, the accuracy is essentially perfect. Due to the cross-correlation measurement technique, there is normally a dropout near zero flow.
Rehabilitation and development of fish habitats are potential techniques for achieving sustainable development in coastal seas. Recent projects in the Strait of Georgia and Puget Sound to examine this possibility have conducted trials or experiments with sedge marshes ( Carex lyngbye]~ (26 sites) and eelgrass beds ( Zostera marina) (14 sites). Some studies have been appropriate for examining the potential compensation of wetland losses from industrial developments, but many were experimental and small scale. Larger scale projects and longer term monitoring are needed to confirm that the policy goals of no net loss or net gain in fish habitat can be met using these techniques.

Access historical weather, climate data, and related information for numerous locations across Canada. Temperature, precipitation, degree days, relative humidity, wind speed and direction, monthly summaries, averages, extremes and Climate Normals, are some of the information you will find on this site.
A download of all the marine data water quality and sediment data held in the BC Environmental Database for the southeastern corner of Vancouver Island - about 1500 entries. These are in four classifications: marine sediment, marine water, plant tissue and soil. By far, the dominant category is marine water. The most-often reported variables as a function of latitude, longitude, depth and datetime are water temperature, salinity, dissolved oxygen, and pH. A great many chemicals (about 600) have been monitored occasionally (all less than 100 times), including entercoc, fecal coli, ammonia, nitrate and nitrite and chlorophyll-a. There are generally two fields for parameters. The first is for the actual value, if it exists. The second field is for a "less than" symbol, implying that the value was below measurement threshold at the time of analysis. It is critical to note that these data are raw, not QA/QC'd, and that anomalies and errors may exist that can only be confirmed through discussion with a MoE biologist, such as is listed in this metadata record.
Study of the plant community is necessary to understand most ecosystems and their component food webs. Data on vascular plants of marsh deltas is of particular interest, since decomposing marsh plants may supply detritus which can be used as food by invertebrates such as amphipods and isopods (Keefe, 1972; Levings, 1973). In some B.C. deltas these invertebrates are consumed by juvenile salmonids(Parker and Kask, 1973; Goodman and Vroom, 1973). The plants also provide a direct food source for waterfowl,seed-eating birds, and herbivorous animals. This repoit describes a survey of the vascular plants of the Squamish River delta. Vegetation maps, species lists, and biomass data are presented, but due to time limitations only the basic characteristics of the complex tidal marsh vegetation were studied.
The present study was coordinated through the water quality management committee of FREMP, and represents one in the series of reports published as part of the WQM Technical Report Series by this committee. The executive summary includes results from additional Fraser River and other starry flounder studies and presents current information regarding advances and trends in the field of contaminant monitoring.
