String acquisition_description
"Total Alkalinity:\\u00a0 Alkalinity was determined using an open cell titration
with HCl (Dickson et al., 2007).\\u00a0 The pH meter was a Corning model 109
which had been adapted so that the millivolt out was logged by computer
through a 14 bit A to D converter.\\u00a0 The electrode was an Orion Ross ultra
semi-micro glass electrode model 8103-BNUWP.\\u00a0 The pH electrode was
standardized with accurate pH buffers.\\u00a0 The tris buffer (
2-amino-2-hydroxymethyl-1,3-propanediol) had a pH of about 8.09 depending on
temperature.\\u00a0 The AMP buffer (2-aminopyridine) had a pH of about 6.79
depending on temperature.\\u00a0 Both were dissolved in artificial seawater at
S = 35 (Dickson et al., 2007, SOP-6a).\\u00a0 Samples and standards were
titrated with a 0.15 M HCl solution in 0.45 M NaCl and the temperature was
measured to the nearest 0.01C using a NIST calibrated platinum
thermometer.\\u00a0 The alkalinity standards generally were precise
alkalinity/total carbon dioxide seawater standards from Scripps Institute of
Oceanography (SIO), but early experiments also used a phosphate buffer
standard comprised of an equal molar mixture of KH2PO4\\u00a0and
Na2HPO4\\u00a0-7 H2O in 0.70 M NaCl.\\u00a0 This phosphate standard was cross
calibrated with the SIO standards.\\u00a0 The procedure used generally gave the
precision of several replicate standard titrations of 0.06% (standard error of
the mean as percent of the mean value).\\u00a0 Alkalinities were determined by
the fitting procedure described in Dickson et al., 2007 (SOP-3b).
Total Carbon Dioxide:\\u00a0 These concentrations were determined by acid
stripping a 1.113 ml volume of water sample or TCO2\\u00a0standard, trapping
the expelled CO2, and then injecting it into a Shimadzu Model GC-8A gas
chromatograph with a thermal conductivity detector (Christensen, 2008).\\u00a0
Two standards were employed, ones made from prebaked and freshly made Na2CO3,
and the previously mentioned SIO total carbon dioxide seawater
standards.\\u00a0 This analytical system obtained a precision of about 0.06%
(standard error of the mean as percent of the mean).\\u00a0 However, in the
results listed in this report, precision was less, averaging about 0.25%
(standard error of the mean as percent of the mean) because sample analysis
time was speeded up causing slightly less efficient trapping of the sample's
CO2.\\u00a0
Salinity and Nutrients:\\u00a0 Salinity was determined using an Autosal 8400A
conductivity salinometer with IAPSO standard seawater standards.\\u00a0
Replicate determinations of a single sample were made until two consecutive
readings of conductivity matched within +/- 0.002 ppt.\\u00a0 Nutrients were
determined by autoanalyzer using the methods for nitrate and nitrite of
Armstrong et al. (1967) and Pavlou (1972), for ammonium of Koroleff (1970) and
Slawyk and MacIsaac (1972), for dissolved inorganic phosphate (Drummond and
Maher, 1995), and dissolved silicate (Armstrong et al., 1967).\\u00a0
Concentrations were measured in mol L-1\\u00a0and converted to mol
kg-1\\u00a0based on the sample's sigma-t value computed from the sample's
salinity and the laboratory temperature during analysis.
Calculation of Carbonate System Parameters:\\u00a0 Carbonate system parameters,
include total pH, were calculated from the measured chemistry of the water
samples using the carbonate equilibrium model, CO2SYS (DOE, 1994; Lewis and
Wallace, 1995).\\u00a0 This program employs the equilibrium coefficients of Roy
et al. (1993) for carbonate coefficients, K1 and K2, of Weiss (1974) for
carbon dioxide, K0, of Dickson (1990a) for borate, of Dickson and Riley (1979)
for fluoride, of Dickson (1990b) for sulfate, and of Millero (1995) for
phosphate (kp1, kp2, kp3) and silicate.\\u00a0 Seawater density at atmospheric
pressure was that of UNESCO (1981).";

"The project description is a modification of the original NSF award abstract.
This research project is part of the larger NSF funded CRI-OA collaborative research initiative and was funded as an Ocean Acidification-Category 1, 2010 award. While attention concerning impacts of predicted acidification of the world's oceans has focused on calcifying organisms, non-calcifying plankton may also be vulnerable. In this project, the investigator will evaluate the potential for impacts of ocean acidification on the reproductive success of three species of planktonic copepods in the genus Calanus that are prominent in high latitude oceans. C. finmarchicus dominates the mesozooplankton biomass across much of the coastal and deep North Atlantic Ocean. C. glacialis and the larger C. hyperboreus are among the most abundant planktonic copepods in the Arctic Ocean. Previous research showed that hatching success of C. finmarchicus eggs was severely inhibited by increased CO2 and lower pH in seawater, but only tested at an extreme level. Preliminary results in the investigator's laboratory indicate that hatching success of C. finmarchicus is substantially reduced at increased seawater CO2 concentrations corresponding to pH levels between 7.9 and 7.5. Predictions of likely decline of surface pH levels to 7.7-7.8 over the next century raise questions about impacts on Calanus population dynamics if these preliminary results are confirmed. C. finmarchicus, for example, is presently at the southern edge of its range in the Gulf of Maine. The combination of higher surface layer temperature and lower pH may inhibit reproductive success during the late summer/fall bloom, which the PI hypothesize is critical to sustain the overwintering stock in this region. The investigators will collect C. finmarchicus females from the Gulf of Maine and, with the assistance of Canadian colleagues, C. glacialis and C. hyperboreus females from the deep lower St. Lawrence Estuary. They will conduct laboratory experiments in which hatching success, development and growth of Calanus nauplius stages are measured in controls of natural seawater and at a series of treatments in which CO2 concentrations, pH and temperature are rigorously controlled to represent possible future states of the northern ocean. The investigators will measure present surface and deep pCO2 and pH across the Gulf of Maine, including its deep basins, during a research cruise. The study will evaluate the hypothesis that predicted levels of CO2 increase in the northern ocean will impact population dynamics of the Calanus species. Using the results from the research cruise and a recently developed 1-D, Individual-Based life cycle model, the PI will explore in detail scenarios of impact of higher temperature and lower surface and deep pH on population dynamics of C. finmarchicus in the Gulf of Maine.
The lipid-rich Calanus species are considered key intermediary links between primary production and higher trophic levels in North Atlantic and Arctic Ocean food webs. Impacts of higher surface temperature and lower pH on reproductive success may potentially lead to profound changes in energy transfer and structure of pelagic ecosystems in the northern oceans. In the Gulf of Maine, C. finmarchicus serves as primary prey for herring, sand lance, and mackerel, as well as the endangered northern right whale, warranting thorough evaluation of ocean acidification effects on its population dynamics.";

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").
