    String acquisition_description 
"The OCC/GLOBEC survey occurred along the coastal waters of the Gulf of Alaska
and in Shelikof Strait, AK during 2001-2004. Transects sampled during the
survey were perpendicular to shore and extended from nearshore across the
continental shelf to oceanic waters beyond the 200-m shelf break. The survey
was conducted aboard the contract fishing vessel F/V Great Pacific during
2001-2002 and 2004, and aboard NOAA Ship Miller Freeman during 2003.
 
Fish samples were collected in a 198-m long mid-water rope trawl with
hexagonal mesh wings and body, and a 1.2-cm mesh liner in the codend. The rope
trawl was towed at 6.5 to 9.3 km \\u2022 hour-1, at or near surface, and had a
typical spread of 40-m horizontally and 15-m vertically. All tows lasted 30
minutes and covered 2.8 to 4.6 km, and sampling was done during daylight
hours; however, tows occurred during night as part of a 24-hour repeat
sampling of a single station for one day during 2001 and 2003.
 
Once the net was hauled aboard, salmon and other fishes were sorted by species
and counted. Standard biological measurements including fork length, body
weight, and sex were taken from sub-samples of all salmon species. Sub-samples
of juvenile pink (Oncorhynchus gorbuscha), chum (O. keta), and sockeye (O.
nerka) salmon were frozen whole for laboratory analyses of food habits,
otolith hatchery thermal marks (pink and chum salmon), and genetic analysis
(chum salmon).
 
Plankton samples were collected using a 1-m2 Tucker trawl fitted with a 505-um
mesh net that was towed near surface (approximately 1 knot) for 5 minutes
(2001-2003 surveys). During 2004, plankton samples were collected using a WP-2
net fitted with a 253-um mesh net that was deployed vertically to a depth of
100-m depth. The volume of water filtered by the net was estimated using flow
meters. Plankton samples were transferred into vials, preserved in 5% formalin
onboard the ship, and stored until a laboratory analysis was completed.";

Tucker designed the net to collect animals associated with the deep scattering layers, principally euphausiids, siphonophores, and midwater fish. (from Wiebe and Benfield, 2003). Currently used Tucker Trawls usually have 1-m2 openings and can have a single net or multiple nets on the frame.";

"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.";

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.
