Help Page for Current Data
Current (water velocity) stations that have been analyzed and released
for raw data dissemination are displayed. The list of available
stations is expanded continuously as more data sets are processed.
Users may enter keywords to search for particular stations
over all fields (station ID, station name, project, and year)
or over a particular field. Users can also sort the result list
by clicking on the relevant column header. See Figure 1.
Relevant metadata for a station, such as deployment
coordinates, deployment dates in UTC (Greenwich) and approximate
station depth are given.
Currents data is collected at various locations
with respect to the instrument.
Station Data Retrieval/Plotting
Speed and direction data can be retrieved and
plotted automatically for a selected station at a specific depth
by clicking on the "View Plot/Data button. A maximum of
31 days of data can be
retrieved at one time.
Browsing Data Sets: Users may also browse through data sets via previous/next links above the plot. The links automatically allow one to move ahead or back by the same number of days in the data set as previously requested. See Figure 4. Users may only request data within the deployment dates. If the previously requested data set is already at either the beginning (deployment start) or at the end (deployment end), then no link is available.
Downloading and Printing Data/Plots: Plots and data sets may be downloaded by selecting the appropriate link below the plot: "Save Plot" for plots, TXT to save as a text file as shown on the webpage, and CSV to save as a comma-delimited (CSV) file. TXT files may have blank lines indicating data gaps, whereas the CSV file omits any blank lines. The plot and data may also be viewed in a format suitable for printing by selecting the "Printable Plot" or "Printable Data Listing" links.
