Fisheries and Oceans Canada (DFO) has been conducting surface water trawl surveys since 1992 in the coastal waters of British Columbia, Washington, Oregon and Alaska and in the high seas of the Gulf of Alaska. These surveys initially focused on determining the migratory patterns (1992-2002) and on the growth and physiology (2003-2016) of juvenile Pacific Salmon. Since 2016, these surveys have been broadened to monitor the whole pelagic ecosystem, retaining a focus on juvenile Pacific Salmon. Data were collected from sites in the inland sea waters of British Columbia and Washington State, USA, that comprise the Strait of Georgia, Strait of Juan de Fuca and Puget Sound since 2001 and are ongoing.

These data were created under DFO’s Strategic Program for Ecosystem-based Research and Advice - Aquatic Invasive Species Program: “Evaluation of the movement of marine infrastructure as a pathway for aquatic invasive species spread”. This geodatabase contains floating dock locations in coastal waters of the Pacific Northwest, from Puget Sound, Washington to Southeast Alaska. These data were assembled by Josephine Iacarella and used in an analysis to understand the role of floating infrastructure as a vector in the spread of marine nonindigenous species (Iacarella et al., 2019). The data are represented as point vectors, though docks have associated size estimates. Data were collected with the aim to have the most accurate representation of coastal coverage of structures in 2017. The most recent images from Google Earth were used, though in some areas these date back a few years.Floating docks included those that extended into the subtidal and were not fixed on pilings. Dock locations were binned into size categories, with small docks and associated marina structures grouped together as ‘marina areas’ based on spatial clustering and a visual estimate of size (haphazard measurement selection, n=35 per category; small: 57.2 m2 ± 6.7, medium: 379.1 m2 ± 42.8, marina area: 4,453.5 m2 ± 744.4). A total of 7,809 floating dock sites were recorded, covering an estimated area of 2.3 km2.

These data sets provide information pertaining to shrimp and bycatch estimates associated with otter-trawling and trapping (November, 2000) and beam-trawling (February, 2001) in Simoom Sound. Data sets were compiled and formatted by Meagan Mak.Abstract from report:As part of a project investigating possible modification of marine ecosystems by shrimp trawling and trapping, we obtained information on catches offish, shrimp, prawns , and bycatch organisms as well as weight, sex ratios , egg location and colIateral damage to several species of pandalids and eualids. Focusing on the humpback shrimp (Pandalus hypsinotus), we assessed damage to the rostrum, carapace, abdomen, and tail fan on specimens caught by beam trawling, otter trawling, and trapping. Data are given from a preliminary study conducted in Northumberland Channel in June 2000 and more comprehensive sampling from Simoom Sound in November 2000 and February 2001.

The rationale for developing this product was the recognized need for a standard and adaptable marine grid that could be used for planning or analysis purposes across projects. This nested grid has five spatial resolutions: 8km, 4km, 2km, 1km, and 500m. It covers the extent of the EEZ on the Canadian Pacific coast, and further east in order to encompass the Fraser River Delta and Puget Sound to account for ecological importance.

Fish Habitat Type Data for Ministry of Natural Resources and Forestry's Parry Sound District used for fisheries management.

These data sets provide information pertaining to abundant taxa including bottom-dwelling shrimp and fish along trawling and trapping transects in Simoom Sound at November, 2000, and February, 2001. Data sets were compiled and formatted by Meagan Mak.Abstract from report:This study is a component of a larger project designed to compare the effects of shrimp trawling and trapping gear on shrimp, fish and the benthic habitat of Simoom Sound located in Broughton Archipelago, British Columbia, Canada. Otter-trawling, beam-trawling, and trapping took place in three distinct experiment blocks of the central seabed of the Sound. In turn, each block consisted of replicate transects, where a towed submersible video-camera surveyed shrimp and fish before and after trawling. Video surveys were deployed only before trapping. From the video surveys, we determined the abundance of common shrimp taxa and fish.

During the period of 1987 to 1994, Robin J. LeBrasseur and N. Brent Hargreaves lead a juvenile salmon predation research project in Alberni Inlet and Barkley Sound BC. This dataset contains the research survey catch data and individual fish examinations data.

These datasets provide information pertaining to sediment grain size, porosity, organic content, total carbon and nitrogen concentrations, trace element concentrations, chlorophyll and phaeopigment concentrations, and meiofauna and macrofaunal abundance in Simoom Sound between November, 2000, and February, 2001. Data formatting of files were performed by Meagan Mak.Sutherland et al (2023) covers the benthic component of a broader project investigating potential modification of marine ecosystems by shrimp trawling and trapping on the central coast of British Columbia. Sediment and infaunal samples were collected before and after fishing with commercial fishing gear consisting of otter-trawl, beam-trawl, and trap-lines. Simoom Sound was sampled in November 2000 and February 2001. Tabulated data of sediment characteristics that include sediment grain size, porosity, carbon and nitrogen content, trace-element, and chlorophyll concentrations are presented in this report. In addition, the infaunal data are comprised of both macrofaunal and meiofaunal communities.

The spatial representation for current Timber Supply Areas (TSA). A Timber Supply Area is a designated area established by the Ministry in order to practice sound, integrated, resource management principles to improve the allowable annual cuts. TSAs were originally defined by an established pattern of wood flow from management units to the primary timber-using industries. They are the primary unit for allowable annual cut (AAC) determination.
