Insights into the origin of perylene from isotopic analyses of sediments from Saanich Inlet, British Columbia
Perylene is an abundant and common polycyclic aromatic hydrocarbon in sedimentary settings, yet its origin remains puzzling. We have investigated the relation of perylene to the amount and type of organic matter in the sediments of Saanich Inlet, a coastal marine anoxic basin. Organic matter is predominantly marine in origin, but the proportions of marine and land-derived components have varied...

متن کاملDeep Coastal Marine Taphonomy: Investigation into Carcass Decomposition in the Saanich Inlet, British Columbia Using a Baited Camera
Decomposition and faunal colonization of a carcass in the terrestrial environment has been well studied, but knowledge of decomposition in the marine environment is based almost entirely on anecdotal reports. Three pig carcasses were deployed in Saanich Inlet, BC, over 3 years utilizing Ocean Network Canada's VENUS observatory. Each carcass was deployed in late summer/early fall at 99 m under a...
متن کاملClimate cyclicity in late Holocene anoxic marine sediments from the Seymour–Belize Inlet Complex, British Columbia
An 8.72 m late Holocene sediment core (VEC02A07) obtained from Alison Sound in the Belize–Seymour Inlet Complex of central British Columbia, Canada was deposited between ∼3500–1000 yr BP under primarily anoxic marine conditions. This core contains a detailed cyclic record of land–sea interactions as evidenced by significant fluctuations in marine primary productivity and changes in the supply o...
متن کاملEat and run: anoxic feeding and subsequent aerobic recovery by Orchomene obtusus in Saanich Inlet, British Columbia, Canada
The lysianassid amphipod Orchomene obtusus (Sars) is known as an epibenthic scavenger, but it is abundant in the water column of Saanich Inlet, British Columbia, a temperate fjord with poorly oxygenated deep water. Sampling with vertically-stratified nets and baited traps indicates that O. obtusus is abundant within the oxycline at 100 to 140 m, is present in anoxic deep waters at low abundance...
