Summary
Abstract: Water quality monitoring is conducted at 26 National Estuarine Research Reserves (NERR) at four locations within or adjacent to the reserve. The following parameters are collected at least every 30 minutes: water temperature, specific conductivity, salinity, percent saturation, dissolved oxygen concentration, water depth, pH and turbidity. All water quality data loggers will be deployed from a known depth from the bottom at each site.

Purpose: Research objectives The YSI electronic data loggers are programmed to measure the water temperature, specific conductivity, dissolved oxygen, pH, and turbidity conditions at 15-minute intervals. Two permanent and two seasonal instruments are located in Kachemak Bay. The permanent sites are located on the northeast side of the bay at the end of the Homer spit and the second on the southwest side of the bay in Seldovia. The seasonal moorings are located at endpoints of the Bay, Port Graham and Bear Cove, spanning a 40 mile distance. The circulation in Kachemak Bay is driven primarily by the 10 meter tidal flux. Regional circulation is characterized by generally cyclonic ocean currents in the Gulf of Alaska flowing onto the shelf off of Cook Inlet. Nutrient rich bottom water is upwelled and mixed with surface water. These enriched waters stream into Kachemak Bay, the inflow tending to stay along the southern shore and the Port Graham and Seldovia instruments, while water flowing out of the bay stays along the Inner Bay and north shore, flowing past the Bear Cove and Homer instruments. These trapped coastal flows separate the bay into two distinct ecosystems and the instruments are positioned to reflect this distinction. As the inflowing water proceeds up the bay, fresh water runoff from the surrounding ice fields and watersheds dilute the salinity and increase the sediment load in the path of the Bear Cove and then Homer instrument. The inflowing water, in the path of the Port Graham and Seldovia instruments, therefore, initially supports a marine system while the north out flowing water of the Bear Cove, and Homer sites, is more estuarine. The Kachemak Bay water quality instruments capture this difference with deployments along the north and south shores. These seasonal moorings monitor the degradation of the marine water along and across the axis of the bay. These data will be used to supplement studies on primary productivity, larval distribution, settlement, recruitment, growth rates, community dynamics, and biodiversity in the bay.
