2010 Oceanographic Research Moorings

2010 Oceanographic Research Moorings
Patrick A'Hearn Olympic Coast National Marine Sanctuary

The 2010 mooring program continued the Sanctuary’s ten-year history of collection of oceanographic parameters for the study of ocean characteristics, hypoxia and harmful algal blooms. There were no major changes for each mooring deployed from previous years. All mooring servicing was done from the sanctuary vessel, RV Tatoosh. Site locations and instrumentation are summarized in the table below. Twenty-one days at sea were spent on the mooring project this year, with 11 of them used for servicing the instrumentation. Three of the moorings were lost in October.

Details of note:

  • CTD cast profiles of temperature, conductivity, pressure, fluorescence and light transmission were conducted at all mooring sites during each visits after the initial deployment. No hypoxia was detected, so no further casts were done. Forty four casts were conducted in total.
  • One mooring was recovered with a grapnel in September; the surface tethers had been cleanly cut
  • One mooring was heavily sedimented in at the October recovery; the nylon line split near the anchor
  • One Kalaloch mooring was heavily sedimented and unable to recover. The subsurface float and nearby instrumentation washed ashore at Sooes Beach in January 2011.
  • A 50 meter depth mooring at Kalaloch has been added for increased spatial coverage of hypoxia.
  • A mooring deployed in 2009 and subsequently lost, was discovered entangled around a 2010 mooring. It was recovered along with its instrumentation.
