Drifters, CT type Dataset Description: <p>RISE - Drifters, CT type<br />
The drifter data come in two varieties: CT and EXP.<br />
All drifters were Brightwaters Corp. drifters.</p> Methods and Sampling: <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>

River Influences on Shelf Ecosystems
<p><strong>River Influences on Shelf Ecosystems (RISE) - A Study of the Columbia River Plume</strong><br /><strong>A Multi-Institutional Collaborative Project Sponsored by the National Science Foundation</strong></p>
<p>In 2004 an interdisciplinary study "River Influences on Shelf Ecosystems" (RISE) was initiated to determine the extent to which alongshore gradients in ecosystem productivity might be related to the existence of the massive freshwater plume from the Columbia River. RISE was designed to test three hypotheses: - During upwelling the growth rate of phytoplankton within the Columbia plume exceeds that in nearby areas outside the plume being fueled by the same upwelling nitrate.<br />
- The plume enhances cross-margin transport of plankton and nutrients.<br />
- Plume-specific nutrients (Fe and Si) alter and enhance productivity on adjacent shelves.</p>
<p>Within those constraints, RISE provides the first comprehensive interdisciplinary study of the rates and dynamics governing the mixing of river and coastal waters in an eastern boundary system, as well as the effects of the plume formed by the mixing processes on rates, standing stocks and community structure of plankton in the local ecosystem. The RISE project, includes 4 field and two different numerical model applications. We collected simultaneous measurements of water chemistry, phytoplankton growth and grazing rates, zooplankton populations, water currents, and turbulent mixing. These are being combined with data from satellites, radar, and moorings, as well as detailed numerical simulations, to develop a deeper understanding of this important ecosystem.</p>
<p>The overall RISE sampling strategy was to compare mixing rates, nutrient supply, and phytoplankton production, grazing and community structure within the plume and outside the plume; i.e. on the shelf to the north of the river mouth, presumed more productive, and on the shelf to the south of the river mouth, presumed less productive, as well as in the important "plume lift off" area (the region where the plume loses contact with the bottom) near the river mouth and the plume "near field". The backbone for this project consists of data collected during four cruises that took place in the seasonally high-flow period (May-June) in each of three years (2004-06) and in a low-flow period in the second year (August, 2005). The sampling was spread over three years to attempt to include interannual differences in processes related to wind and river flow variability. The 21-day length of the cruises ensured that a variety of circulation and growth regimes, including upwelling and relaxation/downwelling and neap/spring tides, were observed.</p>
<p>The field studies used two vessels operating simultaneously. The R/V Wecoma obtained primarily biological and chemical rate data: a) at individual stations on cardinal lines north and south of the river mouth (off Grays Harbor, WA and Cape Meares, OR) and near the river mouth; b) at selected process study stations; and c) at fixed stations near the river mouth during strong neap and spring tides (time series). A towed sensor package was used to obtain micronutrient samples near the sea surface on cardinal lines and other selected transects. Underway measurements included macronutrients (N, P, Si), dissolved trace metals (Fe, Mn), supplemented with discrete samples from the underway system (microscopy, FlowCAM and particulate trace metals). At CTD stations vertical profiles (0-200 m where possible; and 500 m at selected stations) of T, S, vertical shear and currents, dissolved O2, in vivo fluorescence, PAR, chlorophyll a, dissolved macronutrients (NO3, NH4, urea, PO4, SiO4), dissolved trace metals, and heterotrophic and autotrophic plankton composition were obtained. Surface drifters were used to follow the mixing of individual plumes and to provide information on surface currents.</p>
<p>On the R/V Pt. Sur, synoptic mesoscale and fine-scale features were sampled with underway measurements of near-surface T, S, velocity, particle size and concentration, PAR, transmissivity and fluorescence and nitrate+nitrite. The Pt. Sur's Triaxus tow fish provided high-resolution sections of T, S, zooplankton (Laser-OPC), PAR and transmissivity, fluorescence, particle size and concentration (LISST-FLOC25X), UV absorption and nitrate (Satlantic ISUS) and radiance/irradiance (7 channels) through the upper water column to 50 m. Rapidly-executed transects of turbulence and fine-structure were also carried out using the Chameleon profiler; these provide full-depth profiles of T, S, optics (880 nm backscatter and fluorescence), turbulence dissipation rates and turbulent fluxes every 1-3 minutes. During selected periods, transects were repeated hourly to capture the high-frequency evolution in the plume's nearfield and river estuary. Acoustics (surface-deployed 1200 kHz ADCP and 120 kHz echosounder) were used to image fine-scale features of the velocity and backscatter fields, resolving fronts, nonlinear internal waves, and turbulent billows.</p>
<p>The temporal context for observed variability was provided by an array of moored sensors deployed in the plume near field as well as on the shelf north and south of the plume (complemented by the pre-existing long-term estuarine and plume stations of the CORIE/SATURN network. To better resolve regional differences, moorings were moved farther north and south to the cardinal sampling lines after the first year of the program. Surface currents were mapped hourly from shore using HF radar with two simultaneously operating arrays, one with a 40 km range and a 2 km range resolution, the other with a 150 km range and a 6 km range resolution. Satellite ocean color, sea surface temperature, turbidity and synthetic aperture radar (SAR) were also obtained when available.</p>
<p>Two modeling systems were developed or enhanced during RISE. The system developed specifically for RISE employed a structured grid model (ROMS) and was used in hindcast mode (MacCready et al., 2008). The CORIE/SATURN modeling system (Baptista, 2006)- based on two unstructured-grid models (SELFE, Zhang and Baptista, 2008; and ELCIRC, Zhang et al., 2004)- was used in both near real-time prognostic mode and multi-year hindcast mode. Both modeling systems incorporated the estuary in the simulation domain (although at different resolutions) and used realistic river, ocean and atmospheric forcing conditions, tidal forcing, and Columbia River estuary forcing. Wind/heat flux model forcing for ROMS was derived from the 4 km MM5 regional wind/heat flux model. SELFE and LCIRC were also forced by MM5. Conditions on open boundaries were provided by ~9 km resolution models from the Navy Research Laboratory (NRL) (NCOM); ROMS used the smaller domain NCOM-CCS NRL model, SELFE and ELCIRC used the larger domain Global-NCOM model. The biological model is a four-box ("NPZD") nitrogen-budget model that tracks nutrients, phytoplankton, zooplankton, and detritus in every cell of the ROMS grid. The rich RISE biological dataset allowed model validation against not just stocks (chlorophyll, microzooplankton, nutrients) but rates (phytoplankton growth and grazing) directly, a level of validation that is seldom possible. These rate observations also allowed the setting of key model parameters (e.g., zooplankton ingestion rate and mortality) empirically (Banas, et al., 2008).</p>

dataset
<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><br />
<br />
<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><br />
<br />
<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>

<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.<br />
<br />
<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>

Drifter Buoy
Drifter Buoy
PI Supplied Instrument Name: Drifter Buoy PI Supplied Instrument Description:Brightwater Corp. Model 104a Instrument Name: Drifter Buoy Instrument Short Name: Instrument Description: Drifting buoys are free drifting platforms with a float or buoy that keep the drifter at the surface and underwater sails or socks that catch the current. These instruments sit at the surface of the ocean and are transported via near-surface ocean currents. They are not fixed to the ocean bottom, therefore they "drift" with the currents. For this reason, these instruments are referred to as drifters, or drifting buoys.
The surface float contains sensors that measure different parameters, such as sea surface temperature, barometric pressure, salinity, wave height, etc. Data collected from these sensors are transmitted to satellites passing overhead, which are then relayed to land-based data centers.
