Welcome to the

ECOHAB Pacific Northwest mooring data repository

ECOHAB-PNW is a 5-year multi-disciplinary project that studied the physiology, toxicology, ecology and oceanography of toxic Pseudo-nitzschia species off the Pacific Northwest coast.

The project was funded jointly through the Ecology and Oceanography of Harmful Algal Blooms program by the National Oceanographic and Atmospheric Administration Coastal Ocean Program Award No. NA17OP2789 and National Science Foundation Award OCE 0234587. Mooring recovery and deployment on the Canadian Coast Guard Offshore Research and Survey Vessel John P. Tully was made possible by Canadian support to Rick Thomson at the Institute of Ocean Sciences.

One of the many components of this project was to design and maintain three surface moorings to collect time series data of water properties and currents in the Juan de Fuca eddy region.

Links to mooring reports for the following years, 2003, 2004, 2005, 2006 are provided. Data from these moorings are presented in tabular form below.

Velocity data

Each surface mooring had a downward looking Teledyne RD Instruments 300 kHz Workhorse Sentinel ADCP. The velocity from the subsurface mooring at E4 was recorded by an upward looking Teledyne RD Instruments 300 kHz Workhorse Sentinel ADCP. Velocity profile data from these instruments is presented in a matrix format. The first row contains column headers, scan counter, date and time, temperature at the instrument heads, followed by the velocity component. The last column is filled with zeros.

Units are: u component, v component: cm/sec, true North.

Date and time is listed as GDATE to indicate time in GMT, format mm/dd/yy hh:mm.

Temperature and velocity columns have a header indicating the depth rounded to the nearest meter. For example E1u12 indicates the data is from the E1 mooring, u component at 12m.

Note: in 2005 the mooring at E1 was recovered and redeployed leaving a 20 day gap, thus the velocity at E1 is broken into parts a and b. The rest of the years do not have gaps and the full data set will be found in the 200Xa files.
