Oceanographic Research Moorings 2011

2011 Oceanographic Research Moorings
Patrick A'Hearn
Olympic Coast National Marine Sanctuary

The 2011 oceanographic research moorings continued the Sanctuary's 10 year history of collecting ocean temperature, salinity, water velocity, dissolved oxygen and chlorophyll fluorescence data. Few changes were made in 2011, except for slight mooring design modifications and sensor changes resulting from instrument attrition. Site locations and instrumentation are summarized in the table below. Mooring servicing was primarily conducted from R/V Tatoosh, with one deployment conducted from the Sanctuary rigid hull inflatable.

  • locations are almost identical to 2010
  • 2 moorings disappeared without a trace in May or early June
  • 1 mooring disappeared in September, probably lost in storms of late September
  • several moorings were sedimented in by September storms, 2 had to be excavated by divers
  • mooring hardware was slightly modified from 2010 to simplify field operations, reduce costs and reduce instrument entanglement in lines.

Location names include the site depth below mean lower low water (MLLW), in meters. MB – Makah Bay; CA – Cape Alava; TH – Teahwhit Head; KL – Kalaloch; CE – Cape Elizabeth Dissolved oxygen instruments (including conductivity and temperature), if present, are deployed just above the ocean floor. Other conductivity, fluorescence and velocity measurements are made at a depth of 4m below MLLW. Green shading indicates moorings deployed under the jurisdiction of Washington State Department of Natural Resources Aquatic Lands Right of Entry Agreement 32-A77450.
