    String acquisition_description 
"Seabird abundance and distribution within the SO GLOBEC study area was
investigated using daytime and nighttime (using night vision viewers) survey
work. We also recorded seal observations made within the transect area.
Nighttime surveys were designed to complement daytime surveys.
 
Seabird Daytime Surveys  
 Strip transects were conducted simultaneously at 300 m and 600 m widths for
birds. Surveys were conducted continuously while the ship was underway within
the study area and when visibility was >300 m. For strip transects, two
observers continuously scanned a 90\\u00ef\\u00bf\\u00bd area extending the
transect distance (300 m and 600 m) to the side and forward along the transect
line. Binoculars of 10X and 7X magnification were used to confirm species
identifications. The 7X pair of binoculars also included a laser range finder.
Ship followers and bird observed to be attracted to the ship were noted at
first occurrence. These observations will be down-weighted in the analyses
because these individuals may have been attracted to the ship from habitats at
a distance from the ship. For each sighting, transect (300 m or 600 m),
species, number of birds, behavior, flight direction, and any association with
visible physical features, such as ice, were recorded. Distances were measured
either by a range finder device as suggested by Heinemann (1981) or by the
laser distance finder (when in the ice). Marine mammal sightings within the
transect were also recorded.
 
Surveys were conducted from an outside observation post located on the port
bridge wing of the RVIB N.B. Palmer. When it was not feasible to conduct
surveys from this observation post, we surveyed from the inside port bridge
wing.
 
Seabird Nighttime Surveys  
 ITT 200/210 Binocular Night Vision Viewers were used during one half-hour
survey periods while on the survey grid. Surveys were a minimum of an hour
apart. Observations were made from the bridge wing during NBP0104 and outside,
from a dark area on the 01 deck, during NBP0103. Observers scanned back and
forth looking for birds. Species and behavior of the bird was recorded for
each observation. Observations were not conducted when visibility with the
night vision viewer was less than 100 m from the ship.";

Using tabledap to Request Data and Graphs from Tabular Datasets

tabledap lets you request a data subset, a graph, or a map from a tabular dataset (for example, buoy data), via a specially formed URL. tabledap uses the OPeNDAP (external link) Data Access Protocol (DAP) (external link) and its selection constraints (external link).

The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.

Tabledap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
Thus, the query is often a comma-separated list of desired variable names, followed by a collection of constraints (e.g., variable<value), each preceded by '&' (which is interpreted as "AND").

For details, see the tabledap Documentation.
