Description:

Abstract:

This dataset illustrates the density of marine vessel traffic within 5 km by 5 km grid cells for Canada's Pacific waters for the summer months (May to September) of 2007. Traffic is broken down into the following categories: Carrier, Cruise, Fishing, Tanker and Tug. Data is also provided for Ferry and all traffic but was not used by the BCMCA.

Purpose:

This dataset was initially developed to support research on a model of the risk of encountering oil spills for seabirds considered vulnerable to oil pollution. Shipping densities were used as a proxy for the risk of oil spills.
For the BCMCA, the dataset's purpose is to illustrate the distribution and density of vessel traffic in the summer for the following features: Carrier Vessel Density - Summer 2007, Cruise Vessel Density - Summer 2007, Fishing Vessel Density - Summer 2007, Tanker Vessel Density - Summer 2007, and Tug Vessel Density - Summer 2007.
The British Columbia Marine Conservation Analysis (BCMCA) is a collaborative project assembling and analyzing spatial information about Canada's Pacific Ocean. The overall goal of the BCMCA is to identify marine areas of high conservation value and marine areas important to human use. Results of the project are intended to inform and help advance marine planning initiatives in BC by providing collaborative, peer-reviewed scientific analyses based on the best ecological and human use spatial data at scales relevant to a BC coast-wide analysis.

Supplemental_Information:

This dataset is based on ship monitoring data from the Canadian Coast Guard's Marine Communications and Traffic Services (MCTS) system. All ships operating in Canadian waters must obtain Vessel Traffic Services (VTS) clearance before beginning a voyage from a Canadian location or before entering Canadian waters. The Coast Guard monitors ship traffic using radio communication, radar detection and an Automatic Identification System. The Coast Guard documents ship position approximately every 4 minutes with ship-identification (Lloyd's Register name and number), flag-state (country of registry), ship-type and size.

Data_Quality_Information:

Completeness_Report:

Included in this database are ships over 20m in length, and ships engaged in towing or pushing any vessel or object more than 20m in length (other than fishing gear) that had a combined length of more than 45 m. The database does not include vessels towing or pushing inside a log booming ground, pleasure yachts less than 30 m, or fishing vessels less than 24 m and 150 tons gross, which are not required to report their position to the VTS.
There is radar coverage of most of Georgia Strait and a radar station with 90 nautical mile range in the vicinity of Tofino. The radar coverage extends from Juan de Fuca in the south to an area just north of Kyuquot Sound on the west coast of Vancouver Island. All the other areas are tracked by vessels using the established call-in points indicated on the charts. This means that all of the northern area off Vancouver Island, both coasts of Haida Gwaii and the North Coast mainland is without radar coverage.
The information used to create this map does not include vessels transiting the portion of the Juan de Fuca Strait, which is the responsibility of the US Coast Guard.
The map provides minimum estimates of vessel traffic densities for the various traffic types included here and likely underestimates vessel traffic, particularly west of Haida Gwaii. Reasons for this include: 1) limited extents of Coast Guard radar coverage; 2) many of the vessels transiting the area west of Haida Gwaii are not bound for Canadian destinations and therefore not required to report to the Coast Guard; and 3) the Automatic Identification System is still in process of being brought in by VST.
There is no data available from west of the 136 degree longitude to the 200 mile territorial limit.
This dataset does not include data from 2003, which was also produced by the Canadian Coast Guard.

Process_Step:

Process_Description:

Vessel observations were reduced to one uniquely identifiable vessel observation per 5*5 km cell in a GIS grid per hour. For each 5*5km grid cell, data were summarised by calculating total number of uniquely identifiable ship observations per hour that either moved into or out of the focal cell (i.e., ensuring ships were moving). This ensured every vessel observation was tied to a vessel movement.

Process_Step:

Process_Description:

Vessel observations were assigned 5*5 km grid cell labels by spatially joining grid cells with each observation (ESRI: ArcGIS v9.x). Using data-step functions (for e.g., 'proc sort', 'first.obs', and 'lag[]') in the statistics program SAS, the data set was reduced to one uniquely identifiable vessel observation, per cell per hour, and lines were removed when vessel movement between cells was not indicated. 'Proc Tabulate" (SAS v9.x) was used to sum the number of observations per cell (i.e., a spatial grid of values), which we used as an index of relative vessel intensity throughout the British Columbian Exclusive Economic Zone.

Process_Step:

Process_Description:

5x5km cells located outside of Canadian waters were removed from the dataset.
