Description

Disclaimer: All data are subject to revision without notice; exact locations of mooring sites are not yet finalized; exact depths of sensors will be determined at the time of deployment.  Assets labeled as “As Deployed” refer to the April 2014 Phase I Deployment Cruise.

Location and Sampling

Oregon (Newport) Line 

  • Location: 44° 22’N, 125°W to coast
  • Approximate Water Depth: 25-600 m

Washington (Grays Harbor) Line  

  • Location: 46° 51’N, 125°W to coast
  • Approximate Water Depth: 30-550 m

Glider sampling area (approximate):

  • An array of ~6 gliders will travel along five east-west transect lines from approximately the 20-m isobaths to 126 W (and out to 128 W along the Oregon and Washington lines), as well as a north-south transect along 126 W and a north-south transect along the 200 m isobath.
  • Coastal gliders (Teledyne-Webb Slocum Gliders) will fly through the water column along saw-tooth paths, penetrating the sea surface and diving down to depth. These Coastal Gliders will be outfitted with one of two buoyancy engines allowing for maximum efficiency for either shallow (able to dive to 200 m) or deep (able to dive to 1000 m) dives. A roughly even combination of deep and shallow diving coastal gliders will be deployed, sufficient to survey the Endurance Array area.

Description of Infrastructure

  • Two mooring lines: Oregon and Washington Lines
  • Each of these lines contains three fixed sites spanning the slope (~500-600 m), shelf (~80-90 m) and inner-shelf (~25-30 m).
  • Some components of the Oregon Line will be connected to the Cabled Array
  • Six gliders

Station Summary

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 Regional Scale Nodes (RSN) cabled network. 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). Each 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.
