String acquisition_description
"Surveys were conducted in passing mode while the R/V New Horizon was in
transit between stations for hydrographic and zooplankton sampling.
Observations were conducted from the flying bridge during daylight (~0600 to
2030) whenever sufficient visibility (i.e., > 2 nm) and weather (i.e., <
Beaufort 6) allowed. Two observers simultaneously surveyed to the horizon with
25 x 150 binoculars, equipped with compass and reticle. Each observer surveyed
a 100\\u00b0 arc from 10\\u00b0 off the bow (opposite side) to 90\\u00b0 on their
side of the ship. A third observer focused on the track-line by eye, aided
with 7 x 50 hand-held binoculars. Sightings were entered immediately on a
laptop computer connected to the ship's GPS system. Positions of all sightings
were corrected to reflect the actual location of the cetaceans, rather than
the ship's position. The height from the surface of the water to the eyes of
observers on the 25 x 150 binoculars was 10.87 m.";

"Program in a Nutshell
Goal: To understand the effects of climate variability and climate change on the distribution, abundance and production of marine animals (including commercially important living marine resources) in the eastern North Pacific. To embody this understanding in diagnostic and prognostic ecosystem models, capable of capturing the ecosystem response to major climatic fluctuations.
Approach: To study the effects of past and present climate variability on the population ecology and population dynamics of marine biota and living marine resources, and to use this information as a proxy for how the ecosystems of the eastern North Pacific may respond to future global climate change. The strong temporal variability in the physical and biological signals of the NEP will be used to examine the biophysical mechanisms through which zooplankton and salmon populations respond to physical forcing and biological interactions in the coastal regions of the two gyres. Annual and interannual variability will be studied directly through long-term observations and detailed process studies; variability at longer time scales will be examined through retrospective analysis of directly measured and proxy data. Coupled biophysical models of the ecosystems of these regions will be developed and tested using the process studies and data collected from the long-term observation programs, then further tested and improved by hindcasting selected retrospective data series.";

Data Access Protocol (DAP) and its
selection constraints.
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.
