String acquisition_description
"This data set is derived from displacement volume measurements and dry weight
conversion calculations. The MOCNESS-1 plankton sampler has nine rectangular
nets (1m x 1.4 m) with a mesh size of 0.333 mm, which are opened and closed
sequentially by commands through conducting cable from the surface (Wiebe et
al., 1976).
Methods:
Displacement volume measurement: The entire sample plus liquid was measured
in a large graduated cylinder then poured through a sieve into a second
cylinder. The difference in volume is the displacement volume.
Detailed instructions:
Measuring Displacement Volume
Supplies: rubber gloves, safety goggles, 2 1-liter graduated cylinders, 2
smaller graduated cylinders (25 to 100 ml), 2 funnels: 1 wide-necked open
funnel and 1 small-necked one with mesh attached to the inside or a sieve that
fits inside the small-necked funnel, squeeze bottles (water and formalin or
other preservative), sieve of mesh size equal to or smaller than that on
sampling net.
Put on rubber gloves
Remove jars for 1 net from sample box (may be from one to many jars for a
single net sample)
Fill in the data sheet with MOC tow#, date, and net#. jar#
Take first sample to hood. Put on safety goggles.
Remove lid and internal label with long forceps. Get most of zooplankton off
by dipping into jar and place label inside lid after checking that internal
label agrees with lid label.
Remove large (>5cc) animals (medusae, some fish or shrimp) and measure their
displacement volume in the small graduated cylinders:
-Put animal and enough liquid to cover in one small graduated cylinder.-Note
this volume on
data sheet.
-Place small sieve in small funnel and set them on top of second empty small
grad graduated cylinder.
-Pour animal plus liquid into sieve and let drain.
-Note this volume on data sheet as well as the type of animal.
-Return the specimen to the main sample.
Pour the large sample into the 1-liter graduated cylinder using the open
funnel on top (no mesh in funnel). Rinse sparingly the jar, funnel and sides
of the graduated cylinder. Diluting the sample with water could cause it to
rot. Add a little water with the squeeze bottle to bring the level up to an
even line on the graduated cylinder.
Note this volume on the data sheet (sample + liquid)
Place the large funnel containing the sieve or mesh on top of the second,
empty graduated cylinder.
Pour the sample into the empty grad. Don't worry about animals stuck to the
sides of the first grad. Do not add any liquid to wash sample into the second
grad.
Swirl the funnel to remove excess liquid until most of liquid is done
dripping (about 1 minute, but varies sample to sample). Carefully drawing the
samples toward the center with large forceps is sometimes helpful.
Note this volume on data sheet (liquid vol.)
Rinse the graduated cylinder and the mesh-funnel into the sieve with the
hose and return most of the dry sample to the jar using the open funnel.
Use water from faucet with hose to wash the sample on sieve to one side and
then use squirt bottle of water (sparingly) or the preservative filled one to
rinse the sample from sieve to jar.
Add enough of the filtered formalin to fill the jar, dispose of remainder in
appropriate waste container.
- Check the sample's pH and add buffer (sodium borate or borax) if = 8.0.
- Replace cap, swirl if buffer of formalin was added, and rinse outside of
jar.
- Rinse everything well after each net sample.
Dry weight calculations:
dry weight = (dvol/(100.139))(1/1.003); [mg/m3]
integrated dry weight = depth interval * dry weight; [mg/m2]
total dry weight for the entire sampled water column = sum of integrated dry
weights for all nets for one tow; [mg/m2]";

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).";

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.
