In late August of 2018, Rick Shelter caught a 55-inch barracuda off Townsend’s Inlet with a bucktail jig. major source of freshwater for Muchalat inlet is the Gold River. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. It allows scientists and the public to access data, including live videos, of a permanent monitoring system on the seafloor. The volume-normalized N 2 production rates in Saanich Inlet are higher than those measured in the Black Sea and Arabian Sea from 15 N incubation experiments, resulting in the highest values of ΔN 2 /Ar measured to date, despite frequent flushing of oxygenated, low-N 2 water into the basin (Table 1). In addition, understanding community dynamics and influential factors within the fjord is critical to understand the microorganisms’ influence on greenhouse gas emissions, notably methane and dinitrogen. Compound--specific radiocarbon dating of the varved Holocene sedimentary record of Saanich Inlet, Canada R. H. Smittenberg,1,2 E. C. Hopmans,1 S. Schouten,1 J. M. Hayes,3 T. I. Eglinton,4 and J. S. Sinninghe Damste´1 Received 15 May 2003; revised 13 February 2004; accepted 11 March 2004; published 1 May 2004. We conducted a multi-year sediment-trap experiment in Saanich and Jervis Inlets, British Columbia, Canada. The freshwater in the inlet is derived from Saanich Inlet is a fjord in southeastern Vancouver Island, British Columbia (Canada), 26 km long with an average depth of 120 m and a maximum depth of 238 m ().This fjord is seasonally anoxic below 200 m [water depth] due to a 70 m bedrock sill at the north end in Satellite Channel that separates the inlet from open-ocean waters in Haro Strait and that restricts deep water circulation.

Nitrospina and SAR324 (d-proteobacteria) and thiotrophic SUP05 (y-proteobacteria) were predominant in the anoxic basin except during deep-water renewal events. ‘‘Morphology and anoxia in enclosed seas: Aitoliko lagoon – Greece.’’ Geophysical Research, vol 13, 2011. The low oxygen concentration in the Saanich Inlet may be explained by: 1. In contrast, the silty muds originate principally from sources outside Saanich Inlet because of the absence of any significant rivers flowing into it (Gross et al., 1963; Gucluer and Gross, 1964). Saanich Inlet has long been recognized as a model 2S in the bottom waters by summer (Anderson and Devol, 1973; Emerson et al., 1979). Introduction to Saanich Inlet (backgrounder), Depth: 100 m (8) Zalkova ,E., Walsh ,A., D., Stillwell, C., P., Mohn, W., W., Tortell, P., D. and Hallam, S., J. It is a stagnant basin with low current and tides (Gucluer and Gross, 1964). In 2018, the CRD assessed 166 stormwater discharges for E.coli concentrations in the fall and the summer. The resultant reduced freshwater flow into the southern Strait of Georgia was conducive to the free exchange of Saanich Inlet bottom waters with those of well-oxygenated Haro Strait. Abstract. The main driver of freshwater eutrophication is nutrient pollution in the form of phosphorous from agricultural fertilizers, sewage effluent and urban storm water runoff. plankton blooms within the inlet during the spring and fall. It is a stagnant basin with low current and tides (Gucluer and Gross, 1964). There is little fresh water input into the inlet. However, Saanich Inlet is an inverse estuary where the dominant freshwater source is supplied from outside of the inlet, from the Cowichan and Fraser Rivers. Near the seafloor, sulfate (SO42-) reduction succeeds denitrification, producing hydrogen sulfide (H2S) in late spring and summer when nitrate and oxygen are at their lowest concentration [3]. (6) Hobson, L., A. The waters of the Saanich Inlet just east of Spectacle Lake are noted for their sport salmon fishing. VENUS offers archived data, provides remote control of the instruments such as physical and chemical sensors for sampling and permits real time connection to the station [9]. Such water movements introduced significant amounts of nutrients and some phytoplankton seed stock into the photic zone and contributed to the development of blooms of phytoplankton lasting from a few days to … Anaerobic methane oxidation rates were determined in the anoxic sediments of Saanich Inlet, British Columbia. All rights reserved. The inlet is separated from the main waters of the Salish Sea by a shallow (75 m) sill that restricts water inflow. Herein, I develop a trade-off model used to predict the timing of vertical migration of zooplankton. Spectacle Lake is located about 1 mile (2 km) west of Hwy 1 at Malahat Summit. Surface water is largely derived from the Strait of Georgia, influenced by fresh water from the Fraser River, that has its highest discharge in summer, and by fresh water from the Cow-ichan River, which has its highest discharge during winter Saanich Inlet is a temperate marine fjord. During the summer, complete anoxia may develop. The combination of easy access and unusual features has attracted researchers to this glacially carved fjord since the 1930’s. We will stand and fight to protect our coast, harbours and our farmland. Most of the species that we identified were from the algal classes Prasinophyceae, Prymnesiophyceae, and Chrysophyceae and the protistan order Choanoflagellida. In 1962, R.H. Herlinveaux published a compilation of oceanographic data about the inlet, including an assessment of oxygen concentration throughout the year [1] and a focus on monthly variations in sound velocity underwater [1].
