"Dilution batch-culture bioassay experiments were established 11 May 2011 - 15
May 2011 on the SBDOM 11 cruise using water samples collected from the upper
8m of the water column. Water was gravity-filtered from the sampling Niskin
bottle through two mixed cellulose ester filters (1.2 \\u00b5m and 0.2
\\u00b5m). Duplicate 500 mL polycarbonate bottles were filled with 375 mL 0.2
\\u00b5m filtrate (filter sterilized media) and 125 mL 1.2 \\u00b5m filtrate
(bacterial inoculum) collected from the same cast. Bottles were incubated in
the dark at 11degrees C for 10 weeks. Samples for bacterial abundance, DOM,
and community composition by DNA were collected by decanting from the bottle
at specified intervals.
DOC was quantified by high-temperature combustion on a modified Shimadzu
TOC-V. We used 1.5 \\u00b5M DOC as a detection limit for these experiments.
Bacterial abundance was measured using a BD LSRII flow cytometer with an
autosampler attachment. Samples were preserved in sterile cryovials with 0.2%
final concentration paraformaldehyde, then stored frozen until analysis.
Samples were stained with SYBR Green I for enumeration.
DNA was collected from duplicate bottles combined (to conserve volume); 125 mL
from each bottle was vacuum-filtered onto a 0.2 \\u00b5m polyethersulfone
filter and frozen. Samples were lysed in sucrose lysis buffer with 1% w/v
sodium dodecyl sulfate and 0.2 mg mL-1 proteinase-K, and genomic DNA was
extracted using a Qiagen DNEasy silica centrifugation kit. DNA was used to
conduct multiplex amplicon pyrosequencing using primers 8F and 338R, following
the protocol of Nelson et al. (2014; doi: 10.1111/1462-2920.12241). Sequence
analysis was conducted in mothur (Schloss et al. 2009; doi:
10.1128/AEM.01541-09) using a non-redundant subset of the SILVA SSU Ref 16S
alignment database (v111) curated as in Nelson et al. (2014).";

Project Description from NSF Award Proposal and Abstract:
Diatom blooms are known to produce prodigious quantities of DOM upon entering nutrient stress with a chemical composition that varies with the type of nutrient limitation (Si or N). This variable composition likely influences the nutritional value of DOM to microbes driving species successions towards functional groups of heterotrophic prokaryotes that are best able to metabolize particular forms of DOM. To date each side of this coupled system of production/consumption has been examined independently. A few studies have examined how limitation by different limiting nutrients affects the chemical character of the DOM produced by phytoplankton, while others have focused on the fate of DOM without detailed understanding of the mechanisms influencing its initial chemical composition.
We propose to investigate the mechanisms determining the character and fate of DOM produced during temperate diatom blooms. Specifically we will investigate how physiological stress on diatoms induced by different limiting nutrients influences the production, chemical composition of DOM and the microbial community structure that respond to it to better understand the mechanisms driving the accumulation and persistence of DOM in marine systems. The research will involve both laboratory and field experiments. The novel aspects of this work are:
1) We will investigate how limitation by either N or Si impacts the quantity and chemical composition of the DOM released by diatoms.
2) Assess how the differences in the chemical composition of the DOM produced under N or Si limitation affect its lability by examining the productivity, growth efficiency and community structure of heterotrophic bacterioplankton responding to the release of substrates.
3) Predicted DOM dynamics based on (1) and (2) will be tested in the field during diatom blooms in the Santa Barbara Channel, California.
While experiments investigating aspects of either 1 or 2 have been conducted successfully in the past (Lancelot, 1983; Billen and Fontigny, 1987; Goldman et al., 1992; Carlson et al.,1999; Cherrier and Bauer, 2004; Conan et al., 2007) ours will be the first study to combine these approaches in an integrated assessment of the mechanisms governing both the production and fate of DOM produced by diatom blooms experiencing limitation by different nutrients.

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").
For details, see the tabledap Documentation.
