"A total of fourteen 3-4 day integrated aerosol samples were collected during
the US GEOTRACES Western Arctic research cruise (hereafter known as GN01),
which took place from 9th August to 12th October 2015 on the USCGC Healy
(cruise HLY1502). The cruise track consisted of a northward transect from
Dutch Harbor, Alaska, across the Bering Sea, through the Bering Strait and
across the Makarov Basin to the North Pole, followed by a return transect
across the Canada Basin and back across the Bering Sea to Dutch Harbor.
 
Bulk aerosol samples for multiple trace element analyses were collected using
one of five Tisch Environmental high-volume (~1 m\\u00b3 air min\\u207b\\u00b9)
aerosol samplers (model 5170V-BL). For each deployment, 12 replicate 47 mm
diameter Whatman 41 filters were loaded on open-face filter holders (Advantec
MFS) installed on the aerosol sampler on a PVC adaptor plate (Shelley et al.,
2015). Filters were acid-washed before use to reduce trace element blanks,
following the procedure described by Morton et al. (2013). The samplers were
deployed on the ship\\u2019s flying bridge, ~23 m above sea level, to minimize
the influence of sea spray on samples. Samplers were controlled by wind speed
and direction, through a Campbell Scientific CR800 data-logger interfaced with
an anemometer and wind vane set up in close proximity to the samplers, in
order to eliminate contamination from the ship's stack exhaust. This setup was
used to restrict sampling to periods when relative wind speed and direction
were >0.5 m s\\u207b\\u00b9 and from within \\u00b160\\u00b0 of the bow of the
ship, respectively, for at least five continuous minutes.
 
The soluble aerosol fraction was measured using a variation of the flow-
through extraction technique described in Buck et al. (2006). The aerosol-
laden filter was placed in a Teflon filter holder over a 0.2 um polycarbonate
backing filter. While under vacuum, 100 mL of ultrapure deionized water (>18
M\\u2126\\u2219cm) was poured over the filter and the leachate solution
collected in a 100 mL LDPE bottle. Following acidification with Teflon-
distilled hydrochloric acid, the samples were analyzed for trace element
concentration by a quadrupole inductively coupled mass spectrometer (Perkin
Elmer Nexion 300D) coupled with a SeaFAST3 sample introduction and
preconcentration system (Elemental Scientific) at the Skidaway Institute of
Oceanography.";

"Description from NSF award abstract:
In pursuit of its goal \"to identify processes and quantify fluxes that control the distributions of key trace elements and isotopes in the ocean, and to establish the sensitivity of these distributions to changing environmental conditions\", in 2015 the International GEOTRACES Program will embark on several years of research in the Arctic Ocean. In a region where climate warming and general environmental change are occurring at amazing speed, research such as this is important for understanding the current state of Arctic Ocean geochemistry and for developing predictive capability as the regional ecosystem continues to warm and influence global oceanic and climatic conditions. The three investigators funded on this award, will manage a large team of U.S.scientists who will compete through the regular NSF proposal process to contribute their own unique expertise in marine trace metal, isotopic, and carbon cycle geochemistry to the U.S. effort. The three managers will be responsible for arranging and overseeing at-sea technical services such as hydrographic measurements, nutrient analyses, and around-the-clock management of on-deck sampling activites upon which all participants depend, and for organizing all pre- and post-cruise technical support and scientific meetings. The management team will also lead educational outreach activities for the general public in Nome and Barrow, Alaska, to explain the significance of the study to these communities and to learn from residents' insights on observed changes in the marine system. The project itself will provide for the support and training of a number of pre-doctoral students and post-doctoral researchers. Inasmuch as the Arctic Ocean is an epicenter of global climate change, findings of this study are expected to advance present capability to forecast changes in regional and globlal ecosystem and climate system functioning.
As the United States' contribution to the International GEOTRACES Arctic Ocean initiative, this project will be part of an ongoing multi-national effort to further scientific knowledge about trace elements and isotopes in the world ocean. This U.S. expedition will focus on the western Arctic Ocean in the boreal summer of 2015. The scientific team will consist of the management team funded through this award plus a team of scientists from U.S. academic institutions who will have successfully competed for and received NSF funds for specific science projects in time to participate in the final stages of cruise planning. The cruise track segments will include the Bering Strait, Chukchi shelf, and the deep Canada Basin. Several stations will be designated as so-called super stations for intense study of atmospheric aerosols, sea ice, and sediment chemistry as well as water-column processes. In total, the set of coordinated international expeditions will involve the deployment of ice-capable research ships from 6 nations (US, Canada, Germany, Sweden, UK, and Russia) across different parts of the Arctic Ocean, and application of state-of-the-art methods to unravel the complex dynamics of trace metals and isotopes that are important as oceanographic and biogeochemical tracers in the sea.";

"NSF Award Abstract:
In this project, a group of investigators participating in the 2015 U.S. GEOTRACES Arctic Ocean expedition will study the distribution of a variety of trace elements in seawater, sea ice, and marine air. It is important to understand where they are and how they move in the Arctic because some trace elements are essential to life, others are known biological toxins, and still others are important because they can be used as tracers of a variety of physical, chemical, and biological processes in the sea. In common with other multinational initiatives in the International GEOTRACES Program, the goals of the U.S. Arctic expedition are to identify processes and quantify fluxes that control the distributions of key trace elements and isotopes in the ocean, and to establish the sensitivity of these distributions to changing environmental conditions. This multi-institutional team of ocean trace element experts will focus its attention on the importance of aerosol, precipitation, and sea ice melt water in trace element cycling. Results from this work will be disseminated through public educational initiatives, such as web communications and outreach to members of the public, including indigenous populations in Alaska. The project will also provide training for graduate and undergraduate students in biology and chemistry.
Atmospheric deposition is an important pathway and transport mechanism of both natural aerosols and contaminants to the ocean. Relative to other regions, atmospheric deposition rates in the Arctic are low and aerosols and dissolved chemicals in precipitation may be deposited directly to the sea surface or, unique to polar regions, onto sea ice. Given the unique biogeochemical processes of the region and its rapid changes in response to global climate change, quantifying the current atmospheric deposition of trace elements and isotopes to differing catchments (ocean, sea ice, and melt ponds) in the Arctic is critical to our ability to predict how their distribution may evolve over time. In this study, aerosol, precipitation, and melt water samples will be collected and analyzed for trace elements and isotopes in order to evaluate the impacts on the surface ocean and sea ice chemistry from natural and anthropogenic aerosols. Through this project, collected atmospheric samples from the Arctic will also be made available for distribution to the broader scientific community.";

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 (external link) Data Access Protocol (DAP) (external link) and its selection constraints (external link).

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.
