Coastal Endurance

The Endurance Array is a multi-scaled array utilizing fixed and mobile assets to observe cross-shelf and along-shelf variability in the coastal upwelling region of the Oregon and Washington coasts. The array also provides an extensive spatial footprint that encompasses a prototypical eastern boundary current regime and connectivity with the Cabled Array.

The backbone of the Endurance Array includes two cross-shelf moored array lines, the Oregon Line (also called the Newport Line) and the Washington Line (also known as the Grays Harbor Line). Nominally, the Oregon Line is located at 44o 35’N, -125oW to coast. The Washington Line is nominally located at 47oN, 125oW.

Each of these lines contain three fixed sites spanning the slope (~500-600 m), shelf (~80-90 m) and inner-shelf (~25-30 m). The three sites across the shelf and slope are associated with unique physical, geological, and biological processes. All six sites contain fixed sensors at the top and bottom of the water column paired with an adjacent water column profiler.

The Oregon and Washington Lines are both affected by wind-driven upwelling and downwelling, but shelf stratification and upper-ocean properties are influenced differently at each location by the Columbia River outflow. The Washington Line is North of the Columbia River outflow and the Oregon Line is South of it. Observations at both locations allow for a greater understanding of coastal ocean ecosystem responses to climate variability. Mooring lines provide synoptic, multi-scale observations of the eastern boundary current regime. Coastal Gliders bridge the distances between the fixed sites and to allow for adaptive sampling.
