<div><p><strong>CT drifters</strong><br />
CT drifters recorded conductivity (C) and temperature (T) in addition to position (± 3 m) and time.<br />
All CT drifters were programmed to record data at 3-minute intervals.<br />
Additionally, all CT drifters were deployed in a surface configuration.<br />
The buoy itself spanned the top 1.25 m of the water and CT data was recorded at 1.25 m depth.<br />
Processing of the data included linearly interpolating all data onto a 3-minutely time vector.<br />
The data were snipped, meaning only data collected while in water are provided.<br />
Raw CT data is given in addition to calibrated CT data (in case calibrations change).<br />
Calibrations were performed and provided by Tom Wilson at Brightwaters Corp.<br />
The calibrated CT data were used to calculate salinity and density, which are also included.<br />
Finally, east and north velocity components, also provided, were calculated by central-differencing<br />
of position data.</p>
<p>Note: BCO-DMO has compiled the separate files into one, single dataset. The original file names can be found in the "<span style="font-size:13px">Drifter_Data_File" column of the dataset.</span></p>
<p><em>File naming:</em><br />
CT drifter files are named according to:<br />
Drifter PTT ID_MonthDay_Cruise.txt<br />
For example, a file named 22362_A19_R3W.txt contains drifter data recorded by<br />
drifter #22362 starting on August 19th, of the 3rd RISE cruise aboard the R/V Wecoma.<br />
Cruises were:<br />
R1W - July 2004<br />
R2W - May/June 2005<br />
R3W - August 2005<br />
R4W - May/June 2006</p>
<p><em>Data are in the following units:</em><br />
Lon - Decimal degrees<br />
Lat - Decimal degrees<br />
Date/Time - Pacific Daylight Time (PDT)<br />
Temperature - Celsius (°C)<br />
Conductivity - (mS cm-1)<br />
Salinity - (psu)<br />
Density - (kg m-3)<br />
Velocity components - (m s-1)</p></div>

The drifter data come in two varieties: CT and EXP.<br />
All drifters were Brightwaters Corp. drifters.</p></div>

<div><p><strong>BCO-DMO Processing Notes</strong><br />
Generated from original files contributed to BCO-DMO as a zipped data/docs file by Raphael Kudela.</p>
<p><strong>BCO-DMO Edits:</strong><br /><strong>Drifter Documentation/Metadata:</strong><br />
- generated a file of all RISE drifter "metadata" from individual .xls yearly files<br />
- file includes drifterids, models, deployment/recovery dates/times, deployment lats/lons, and comments<br />
- header file was generated from data contained in the .xls files<br />
- empty cells filled with "nd" (no data)<br />
- Added Cruise names such as RISE04W1, etc for consistency with other data sets<br /><strong>Drifter data files:</strong><br />
- simple awk script generated to reformat RISE drifter data to BCO-DMO format<br />
- date reformatted to YYYYMMDD<br />
- time reformatted to HHMMSS<br />
- lat/lon positions output unchanged<br />
- remaining data output unchanged</p></div>
