"Culturing
The marine diatom Thalassiosira weiss\\ufb02ogii Grunow (strain CCMP 1010) was
cultured in sterile filtered natural North Sea water (Schleswig-Holstein,
Germany) or Baltic Sea water (Schleswig-Holstein, Germany). The medium was
enriched with f/4 concentrations of macro- and micronutrients (nitrate,
phosphate, silicic acid, trace metal mixture, vitamin mixture (Guillard and
Ryther, 1962). All experiments were performed in sterile 2.1 L Schott Duran
glass bottles. These bottles were made of borosilicate glass (filters UV
radiation <310 nm) except for the quartz glass bottles (pure silica without UV
radiation filter) used in the UV experiment. The cultures were either
incubated in climate chambers with 400 \\u2013700 nm radiation or 10 cm below
water level at low tide in Kiel Fjord in May 2011. Water temperature and light
irradiance data were obtained from the weather station maintained by the
GEOMAR institute in Kiel, Germany. Growth conditions for the various
treatments, i.e. salinity, pH, temperature, and irradiance are given in Table
1. pH values (reported on free scale) were measured \\u00a0with separate glass
and reference electrodes (Metrohm) and calculated with equation 3 from DOE
2007 chapter 6b (Dickson et al., 2007) as described in (Bach et al., 2012).
Cultures were inoculated with densities of 20 cells ml-1. \\u00a0Cell densities
and equivalent spherical diameters were determined with a Coulter Counter
(Beckman Coulter) at the beginning and the end of the experiment,
respectively. When incubations ended, cells were filtered on 47 mm diameter, 5
um mesh size Nucleopore Track-Etch Membrane filters (Whatman) and frozen at
-18 deg C immediately after filtration.";

String projects_0_description
"The bioavailability of nutrients plays a crucial role in oceanic biological productivity, the carbon cycle, and climate change. The global ocean inventory of nitrogen (N) is determined by the balance of N-fixation (sources) and denitrification (sinks). In this three-year project, a researcher from the University of California, Santa Cruz, will focus on developing compound-specific N isotope (d15N) analysis of amino acids as a new tool for understanding N source and transformation of organic matter in paleo-reservoirs. The offsets in the isotopic ratios of individual amino acid groups may yield information about trophic transfer, heterotrophic microbial reworking, and autotrophic versus heterotrophic sources. By measuring and comparing the bulk and amino acid d15N in size-fractioned samples from plankton tows, sediments traps, and multi-cores in oxic and suboxic depositional environments, the researcher will: (1) Provide a proxy of the d15N of average exported photoautotrophic organic matter; and (2) Provide a new level of detail into sedimentary organic N degradation and preservation.
Broader impacts:
This project will improve understanding of the fundamental underpinnings and behaviors of d15N amino acid patterns and how they behave in contrasting sedimentary environments, while also developing a potential paleoceanographic proxy. Funding will support a graduate student and undergraduate research at the institution. The researcher will also conduct community outreach in the form of a workshop/tutorial on the proxy development.";

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").
