    String acquisition_description 
"Thorium isotope samples were collected from the ship\\u2019s Niskin bottle
rosette, and in some cases, surface water (from roughly 15 m depth) was also
collected using a Teflon diaphragm pump (Cole Palmer) operated from the
ship\\u2019s deck. Water was filtered at 0.45 \\u03bcm using Acropak filter
cartridges and acidified to 0.024 M HCl (~pH 1.5) at sea.  
 Surface samples for both trace elements and thorium isotopes were taken
every 12 hours between July 25 and August 3, roughly at sunrise and sunset
(Hawaii Standard Time). This timing was motivated to observe the maximum
possible change in dissolved elemental concentrations since it coincides with
the highest contrast in surface water biomass (maximum at sunset, minimum at
sunrise). Depth profile samples for trace elements were collected on July 30
at 10:00 AM, except for the sample from 180 m, which was collected on August 2
at 4:00 PM, due to a misfiring of the original 180 m Vanes deployment. Thorium
depth profile samples were collected on July 31 at 2:00 AM (station 43 of
KM1513).\\u00a0  
 On KM1427 (December 2014), thorium isotope samples were collected as on
KM1513.\\u00a0
 
The elements Sc, Mn, Fe, Co, Ni, Cu, Zn, Cd, and Pb from the Lagrangian
sampling (KM1513) were analyzed at Texas A&M University using an offline
SeaFAST-pico preconcentration system (ESI, Omaha, NE) and a Thermo Finnigan
Element XR high\\u2010resolution inductively-coupled mass spectrometer (HR-ICP-
MS) housed at the R. Ken Williams Radiogenic Isotope Facility. Notably,
samples were not UV oxidized, and thus cobalt concentrations must be
considered to be operationally defined ICP-labile cobalt (lCo). Accuracy was
assessed by analyzing aliquots of the SAFe D1 seawater consensus standard.
Precision is reported as error bars for each analysis and was assessed using
the standard deviation of duplicate or triplicate analyses of all
samples.\\u00a0
 
Note trace metal data that did not meet the principal of oceanographic
consistency were marked in parentheses in the worksheet. These data could not
be determined specifically to have been contaminated but we treat them with
caution and they were not considered in the publication.
 
Thorium isotopes (232Th and 230Th) were analyzed at MIT by Fe co-precipitation
from 4 L samples, acid digestion, anion exchange chromatography, and a Nu
Plasma II ICP-MS. Accuracy was assessed by analysis of the SWS2010-1 standard
(Anderson et al., 2012) (Table 2) as well as an in-house thorium isotope
standard (MITh-1). Reported uncertainty for thorium isotopes represents the
uncertainty in isotope ratios measured on the ICP-MS.
 
Select samples were also analyzed for dissolved aluminum (dAl) concentrations.
These samples were sub-sampled from the water filtered from the ATE sampler,
filtered directly into 125 mL acid washed PMP bottles and acidified to 0.006 M
HCl and microwaved for 58 seconds/125mL of sample. These samples were then
acidified to 0.012 M HCl (~pH 2) and stored for shipboard analysis on a later
cruise (R/V Revelle cruise RR1815 in November 2018) for dAl using flow
injection analyses. Replicate standards were used to assess precision and
accuracy of this method, and reported errors are the relative standard
deviation of standard analyses.";

"Project summary
The Center for Microbial Oceanography: Research and Education (C-MORE) is a recently established (August 2006; NSF award: EF-0424599) NSF-sponsored Science and Technology Center designed to facilitate a more comprehensive understanding of the diverse assemblages of microorganisms in the sea, ranging from the genetic basis of marine microbial biogeochemistry including the metabolic regulation and environmental controls of gene expression, to the processes that underpin the fluxes of carbon, related bioelements and energy in the marine environment. Stated holistically, C-MORE's primary mission is: Linking Genomes to Biomes.
We believe that the time is right to address several major, long-standing questions in microbial oceanography. Recent advances in the application of molecular techniques have provided an unprecedented view of the structure, diversity and possible function of sea microbes. By combining these and other novel approaches with more well-established techniques in microbiology, oceanography and ecology, it may be possible to develop a meaningful predictive understanding of the ocean with respect to energy transduction, carbon sequestration, bioelement cycling and the probable response of marine ecosystems to global environmental variability and climate change. The strength of C-MORE resides in the synergy created by bringing together experts who traditionally have not worked together and this, in turn, will facilitate the creation and dissemination of new knowledge on the role of marine microbes in global habitability.
The new Center will design and conduct novel research, broker partnerships, increase diversity of human resources, implement education and outreach programs, and utilize comprehensive information about microbial life in the sea. The Center will bring together teams of scientists, educators and community members who otherwise do not have an opportunity to communicate, collaborate or design creative solutions to long-term ecosystem scale problems. The Center's research will be organized around four interconnected themes:
(Theme I) microbial biodiversity,
(Theme II) metabolism and C-N-P-energy flow,
(Theme III) remote and continuous sensing and links to climate variability, and
(Theme IV) ecosystem modeling, simulation and prediction.
  Each theme will have a leader to help coordinate the research programs and to facilitate interactions among the other related themes. The education programs will focus on pre-college curriculum enhancements, in service teacher training and formal undergraduate/graduate and post-doctoral programs to prepare the next generation of microbial oceanographers. The Center will establish and maintain creative outreach programs to help diffuse the new knowledge gained into society at large including policymakers. The Center's activities will be dispersed among five partner institutions:
Massachusetts Institute of Technology,
Woods Hole Oceanographic Institution,
Monterey Bay Aquarium Research Institute,
University of California at Santa Cruz and
Oregon State University
and will be coordinated at the University of Hawaii at Manoa.

Using tabledap to Request Data and Graphs from Tabular Datasets

tabledap lets you request a data subset, a graph, or a map from a tabular dataset (for example, buoy data), via a specially formed URL. tabledap uses the OPeNDAP 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.

• (easy) You can get data by using the dataset's Data Access Form or Subset form. They make the URL for you.
• (easy) You can make a graph or map by using the dataset's Make A Graph form. It makes the URL for you.
• (not hard) You can bypass the forms and get the data or make a graph or map by generating the URL by hand or with a computer program or script.

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.
