"[excerpted from Strom, et al. (2006) Microzooplankton grazing in the coastal
Gulf of Alaska: Variations in top-down control of phytoplankton. Limnol
Oceanogr in press.]
Water drawn from multiple Niskin bottles closed at a single depth was pooled
into two 25-liter polycarbonate carboys. Most often, water was collected from
the depth corresponding to 50% of surface irradiance (50% Io, 3 to 10 m). Once
during April, and once per station during July, water was collected from the
depth of the subsurface chlorophyll maximum (SCM, 12 to 25 m). The contents of
one carboy were gravity-filtered (0.2 um) to generate particle-free filtered
seawater (FSW, the diluent for the dilution series). The contents of the other
were gently pre-screened through 200 um Nitex mesh to exclude macrozooplankton
(WSW, the whole seawater for the dilution series). Using gentle siphoning and
mixing techniques, FSW and WSW were combined in known proportions in
2.35-liter polycarbonate bottles to generate a dilution series consisting of
9, 16, 24, 41, 61, and 100% WSW (each in duplicate). An additional pair of
bottles diluted to 4% was added during the May and July cruises, as well as an
additional pair of 100% WSW bottles to control for the effects of nutrient
enrichment on phytoplankton growth rate. Clean techniques and inert materials
(silicone, polycarbonate) were used throughout.";

"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.
