As part of The Pacific Northwest Coastal Ecosystem Regional Study (PNCERS) the University of Washington under the direction of Dr. Barbara Hickey maintained two offshore moorings, one off Grays Harbor, WA, and one off Coos Bay, OR, from early 1998 through Spring 2000. These moorings included an upward looking Acoustic Doppler Current Profiler (ADCP) providing a time series of temperature at the heads and u,v components of velocity profiles. On the Grays Harbor offshore mooring an Aanderaa Instruments current meter (AA) below the ADCP measured speed, direction and conductivity. A mooring was also maintained in the Coos Bay estuary. Instruments in the estuary included an upward looking narrow band 1200 kHz ADCP providing a time series of temperature at the heads and u,v components of velocity profiles and either an AA or a Sea-Bird Electronics 37 MicroCat recorder to measure temperature and conductivity.

Approximately five and a half months of data from an earlier deployment at the Grays Harbor offshore mooring site were also included. These data consisted of 2 AAs measuring speed, direction, temperature and conductivity at approximately 25 and 30 meters.

Purpose The purpose of the Hickey component of this project was to investigate the physical variability in 3 Pacific Northwest estuaries and their relation to the coastal ocean. In order to do this instruments were deployed in three estuaries, Grays Harbor and Willapa Bay, Washington and Coos Bay, Oregon. Two offshore moorings were maintained off Grays Harbor, Washington and Coos Bay, Oregon. Two sites were sampled in the Coos Bay Estuary, CBEST1, at T-Dock and CBEST2 at the Charleston River. Only one site was sampled in the Grays Harbor Estuary, GHEST1. In Willapa Bay there were 4 sites sampled, a piling at Toke Point, a piling at Nahcotta, WB3, and WB6. In addition, several water property (CTD) surveys were taken both in the estuaries and offshore.

Processing Steps
  • Data Type: u and v components of velocity (calculated); Units: cm/sec; Observation Type: in situ; Sampling Instrument: Aanderaa current meter (AA); Sampling and Analyzing Method: AA instruments measure current speed and direction. Data was sampled in either 30 or 60 minute intervals. Directions were rotated into degrees true north and u and v components of velocity were computed. The data was edited for spurious values.; Data Quality Information: Data were plotted and visually inspected for spurious values
  • Data Type: TEMPERATURE - WATER [WATER TEMPERATURE] (measured); Units: degrees C; Observation Type: in situ; Sampling Instrument: Aanderaa current meter (AA); Sampling and Analyzing Method: AA instruments measured temperature. Data was sampled in either 30 or 60 minute intervals, then edited for spurious values.; Data Quality Information: Data were plotted and visually inspected for spurious values
  • Data Type: Conductivity (measured); Units: mmho/cm; Observation Type: in situ; Sampling Instrument: Aanderaa current meter (AA); Sampling and Analyzing Method: Some AA instruments measured conductivity. Data was sampled in either 30 or 60 minute intervals, then edited for spurious values. Conductivity was converted to salinity (PSS-78) using algorithms from UNESCO Report 44. Temperature data measured by the AA and a constant pressure value approximately equal to the depth were used to compute salinity and in the estuary sigma-t. Data was edited for spurious values.; Data Quality Information: Data were plotted and visually inspected for spurious values
  • Data Type: TEMPERATURE - WATER [WATER TEMPERATURE] (measured); Units: degrees C; Observation Type: in situ; Sampling Instrument: Sea-Bird Electronics 37 MicroCat (C,T) recorder, (SBE 37); Sampling and Analyzing Method: An SBE 37 measured temperature. It was set up to average 4 samples taken every half hour. Data was edited for spurious values.; Data Quality Information: Temperature values were plotted and visually inspected for spikes or spurious values. Data deemed bad were filled using linear interpolation across the bad point(s)
  • Data Type: Conductivity (measured); Units: Siemens per meter (S/m); Observation Type: in situ; Sampling Instrument: Sea-Bird Electronics 37 MicroCat (C,T) recorder, (SBE 37); Sampling and Analyzing Method: The SBE 37 was set up to average 4 samples taken every half hour. Conductivity was converted to salinity (PSU) and sigma-t (kg/m3) using the temperature measured by the SBE 37 and a constant value of 5 decibars. Please note actual depth was 12 meters. Data was edited for spurious values.; Data Quality Information: Conductivity, temperature, salinity and sigma-t values were plotted and visually inspected for spikes or spurious values. Data deemed bad were filled using linear interpolation across the bad point(s)
  • Data Type: u and v components of velocity (measured); Units: cm/sec; Observation Type: in situ; Sampling Instrument: Teledyne RD Instruments 300kHz and 1200kHz Narrow Band Acoustic Doppler Current Profiler (ADCP); Sampling and Analyzing Method: ADCPs were installed on both Coos Bay and Grays Harbor offshore moorings (300 kHz) and a narrow band 1200kHz in the Coos Bay estuary. ADCPs measure water velocity at several depths, referred to as bins. Distance between bins was set to 1 meter in the estuary, 2 meters on the Coos Bay offshore mooring and 1 meter on the Grays Harbor offshore mooring, except the last year which was changed to 2 meters. The sample interval was set to 60 minutes, except the last 2 deployments in the estuary which were set to 30 minutes. All data was rotated to true North. Please see the Readme files for more details on the sampling set up. Data was plotted and edited for spurious values.; Data Quality Information: Data was plotted and visually inspected for spikes or spurious values. All extraneous bins may not have not been removed from the data. In particular, spikes related to side lobe reflections off the surface and subsurface instruments or mooring components may still be present
  • Data Type: TEMPERATURE WATER [WATER TEMPERATURE] (measured); Units: degrees C; Observation Type: in situ; Sampling Instrument: Teledyne RD Instruments 300 kHz and 1200 kHz Narrow Band Acoustic Doppler Current Profiler (ADCP); Sampling and Analyzing Method: The ADCP contains a thermistor that measures temperature at the heads. The temperature is measured every time the instrument pings. Please see the Readme files for details on the sampling set up. Data was plotted and edited for spurious values.; Data Quality Information: Temperature values were plotted and visually inspected for spikes or spurious values
