String acquisition_description
"At sea, animals were captured for physiological experiments using a 1 m
diameter, 150 \\u00b5m (in 2011) or 335 \\u00b5m (in 2012) mesh Reeve net trawl,
or a 1 m2 MOCNESS tow with 150 \\u00b5m mesh nets. Pteropods were placed in
filtered seawater at densities of < 30 individuals liter-1 and acclimated for
at least 8 hours at 20\\u00b0 C, 15\\u00b0C or 10\\u00b0C in temperature
controlled waterbaths. After acclimation, individuals that were in good
condition were put into glass syringe respiration chambers with a known volume
of 0.2 micron filtered seawater for at least four hours.
In 2012 on cruise NH1208, an experiment\\u00a0 was conducted to determine
whether antibiotics changed the metabolic rate of the pteropods. In this
experiment water was treated with 25mg each of Streptomycin and Ampicillin
liter-1 or without antibiotics.
Unless otherwise explicitly stated, the water contained 25mg each of
Streptomycin and Ampicillin liter-1, to prevent bacterial growth, and was
bubbled with certified gas mixes to achieve normal air saturated (21% O2, 380
ppm CO2), high CO2 (21% O2, 800 ppm CO2), low O2 (10% O2, 380 ppm CO2) or low
O2 high CO2 (10% O2, 800 ppm CO2) conditions. Bubbling of 10% O2 achieved a
mean initial O2 concentration of 10-13% in low O2 treatments.
During all experiments, we simultaneously ran a control syringe (without an
animal)\\u00a0 to monitor background respiration of microbes. At the conclusion
of the experiments, we measured the O2 level by withdrawing a sample of water
from the chamber using a\\u00a0 500 \\u00b5L airtight Hamilton syringe and
injected past a Clarke-type O2 electrode (#1302) and meter (#782) in a water-
jacketed injection port (#MC100, Strathkelvin Instruments, North Lanarkshire,
United Kingdom; Marsh and Manahan, 1999). Our resulting O2consumption rates
are reported in \\u00b5moles g-1 h-1 (wet mass). Notes on carbonate chemistry
and net profiles are in the cruise report.";

"A Reeve Net is a conventional ring net with a very large acrylic cylindrical cod-end (30 liters) designed to collect fragile gelatinous animals. The net is lowered to a particular depth and then hauled slowly back to the surface (5-10 m/min). Reeve (1981) also described a double net system with no bridle and flotation at the net mouth that is attached to a roller mechanism that rides on a tow wire.
The roller system is locked in place by a pressure release device. Once below a set pressure, the roller
and nets are released and they float slowly up the wire, gently collecting the zooplankton, without being
influenced by the motion of the vessel and associated vertical wire movements. (from Wiebe and Benfield, 2003)";

A gold or platinum sensing cathode is polarized against an internal reference and, driven by external partial pressure, oxygen from the environment penetrates through the sensor tip membrane and is reduced at the sensing cathode surface. A picoammeter converts the resulting reduction current to a signal. The size of the signal generated by the electrode is proportional to the flux of oxygen molecules to the cathode.The sensor also includes a polarized guard cathode, which scavenges oxygen in the electrolyte, thus minimizing zero-current and pre-polarization time.With the addition of a meter and a sample chamber, the respiration of a small specimen can be measured.

"Modified version of the NSF award abstract:
The impact of ocean acidification on marine ecosystems represents a vital question facing both marine scientists and managers of ocean resources. Thecosome pteropods are a group of calcareous planktonic molluscs widely distributed in coastal and open ocean pelagic ecosystems of the world¡¦s oceans. These animals secrete an aragonite shell, and thus are highly sensitive to ocean acidification due to the water column's changing carbonate chemistry, and particularly the shoaling of the aragonite compensation depth at which seawater becomes corrosive to aragonite. In many regions, however, relatively little is known about the abundance, distribution, vertical migratory behavior, and ecological importance of pteropods. Assessing the likely ecosystem consequences of changes in pteropod dynamics resulting from ocean acidification will require a detailed understanding of pteropod distribution and abundance relative to changing aragonite saturation in the water column.
The primary objective of this project is to quantify the distribution, abundance, species composition, shell condition, and vertical migratory behavior of oceanic thecosome pteropods in the northwest Atlantic and northeast Pacific, and correlate these quantities to hydrography and concurrent measurements of carbonate chemistry, including vertical and horizontal distributions of aragonite saturation. In particular, the project will capitalize on present-day variability in the depth distribution of aragonite saturation levels within and between the Atlantic and Pacific Oceans as a \"natural experiment\" to address the hypotheses that pteropod vertical distribution, species composition, and abundance vary as the compensation depth becomes shallower. Secondary objectives are to develop acoustic protocols for the remote quantification of pteropod abundance for future integration into ocean acidification monitoring networks, and to characterize carbonate chemistry and nutrients along portions of two WOCE/CLIVAR Repeat Hydrography transects (A20 in the Atlantic and P17N in the Pacific) to identify decadal-scale changes in the carbonate system. These hypotheses and objectives will be addressed through two cruises along survey transects between 35 and 50 degrees North in the northwest Atlantic and northeast Pacific involving a combination of station-work and underway measurements, and a comprehensive array of instruments, including acoustic, optical, towed net, hydrographic, and carbonate chemistry sensors and sampling systems.
This highly inter-disciplinary project, combines expertise in zooplankton ecology, acoustics, and marine chemistry. The proposed work will result in a detailed baseline understanding of variability in the horizontal and vertical distribution, as well as species composition, of thecosome pteropods in the northwest Atlantic and northeast Pacific, making a key contribution to zooplankton ecology generally. In addition, by quantifying the response to current spatial variability within and between the Atlantic and Pacific Oceans, the project will provide important information on the likely response of pteropod distribution to future changes in the vertical distribution of aragonite saturation levels, a necessary component in modeling the impacts of ocean acidification on marine ecosystem function, services, and resources.
Ocean acidification is increasingly appreciated as an urgent societal concern. Thecosome pteropods are key prey for a variety of commercially-exploited fish species, and the improved understanding the PIs seek of pteropod distribution and likely response to changing water column carbonate chemistry will have important implications for our understanding of potential effects of ocean acidification on marine resources.";

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").
