Description:

Abstract:

Lagrangian surface currents were measured using drifters equipped with global navigation satellite system (GNSS) receivers. A total of 8 drifter deployments were performed between May 25 and June 8, 2013. For each deployment, drifters were released within the MCR and their positions were recorded until the drifters were recovered. The average duration of the drifter deployments varied between 1.6 h and 17.2 h and the number of drifters released in a deployment ranged between 11 and 84. The initial positions and timing of the release of the drifters relative to the tidal cycle varied throughout the drifter deployments. Digital files containing the drifter data from each deployment are available in NetCDF format.

Purpose:

These drifter deployments were conducted as a part of a larger investigation into the hydrodynamics of the mouth of the Columbia River, Oregon and Washington, in 2013.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Data were reviewed to ensure that only data points that represent the period that each drifter was free-floating are included, and extraneous points were removed (such as points on land or on the research vessel).

Logical_Consistency_Report: All data fall within expected ranges.
Completeness_Report:

Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Horizontal positional accuracy provided by the manufacturer is 10 m.

Process_Step:

Process_Description:

The drifters were each constructed with a 0.5-m section of standard dimension ratio 35 polyvinyl chloride pipe capped at both ends. Holes were drilled into the end caps and a 2.27 kg weight was attached to the bottom of the drifter. Foam collars were attached around the outer diameter of the top caps to provide buoyancy for the drifters. Waterproof cases attached to the top of the drifters housed two types of GNSS receivers. Positioning of the drifters was recorded at 1-Hz intervals using an internally-logging Genie GT-31 L/1 GNSS receiver. Each drifter was also equipped with a SPOT GNSS device that reported drifter positions at 5-min intervals via satellite. The positions from the SPOT GNSS were used in the event that the drifter was not recovered.

Process_Date: 20130301

Process_Step:

Process_Description:

A total of 8 drifter deployments were performed between May 25 and June 8, 2013. For each deployment, drifters were released within the mouth of the Columbia River and their positions were recorded until the drifters were recovered. Deployment and recovery operations were performed from the R/V Parke Snavely and two personal watercraft.

Process_Date: 20130608

Process_Step:

Process_Description:

Data were imported into Matlab to parse the data from one data file into individual drifter deployments. Distance, azimuth and drifter velocity were calculated using the GPS fixes. The data from each deployment were accumulated into NetCDF files for distribution.
