String acquisition_description
"The MOCNESS is based on the Tucker Trawl principle (Tucker, 1951). The
MOCNESS-1 has nine rectangular nets (1m x 1.4 m) which are opened and closed
sequentially by commands through conducting cable from the surface (Wiebe et
al., 1976). In MOCNESS systems, \\\"the underwater unit sends a data frame,
comprised of temperature, depth, conductivity, net-frame angle, flow count,
time, number of open net, and net opening/closing, to the deck unit in a
compressed hexadecimal format every 2 seconds and from the deck unit to a
microcomputer every 4 seconds... Temperature (to approximately 0.01 deg C) and
conductivity are measured with SEABIRD sensors . Normally, a modified
T.S.K.-flowmeter is used... Both the temperature and conductivity sensors and
the flowmeter are mounted on top of the frame so that they face horizontally
when the frame is at a towing angle of 45deg... Calculations of salinity (to
approximately 0.01 o/oo S), potential temperature (theta), potential density
(sigma), the oblique and vertical velocities of the net, and the approximate
volume filtered by each net are made after each string of data has been
received by the computer.\\\" (Wiebe et al., 1985) In addition, depending on the
particular configuration of the MOCNESS-1, data may have been collected from
other sensors attached to the frame : (Transmissometer, Fluorometer,
Downwelling light sensor, and the Oxygen sensor). A SeaBird underwater pump
was also included in the sensor suite.";

String instruments_0_description "The Multiple Opening/Closing Net and Environmental Sensing System or MOCNESS is a family of net systems based on the Tucker Trawl principle. The MOCNESS-1 carries nine 1-m2 nets usually of 335 micrometer mesh and is intended for use with the macrozooplankton. All nets are black to reduce contrast with the background. A motor/toggle release assembly is mounted on the top portion of the frame and stainless steel cables with swaged fittings are used to attach the net bar to the toggle release. A stepping motor in a pressure compensated case filled with oil turns the escapement crankshaft of the toggle release which sequentially releases the nets to an open then closed position on command from the surface. -- from the MOCNESS Operations Manual (1999 + 2003).";

"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.
