"Skeletonema costatum:
Duplicate batch cultures of coastal diatom strain Skeletonema costatum (CCMP
1332) were grown in clear rectangular 20L polycarbonate carboys under six cool
white and two natural s11 type light bulbs providing\\u00a0 ~200 umol photons
s-1 m-2. The cultures were grown under a 12:10 light:dark cycle and mixed by
hand twice per day. Sampling occurred once per day, just before the beginning
of the dark period. The media was designed to assess the carbon partitioning
response under stress from Si, N, and both Si & N -- however, as this
experiment did not proceed as with the other three experiments here (i.e.
especially in terms of initial nutrient concentration design, nutrient uptake
outcomes, growing time, and parameters measured), nearly all further analyses
were not initiated.
Chaetoceros socialis:
Duplicate batch cultures of coastal diatom strain Chaetoceros socialis (CCMP
172) were grown in clear rectangular 20L polycarbonate carboys under six cool
white and two natural s11 type light bulbs providing\\u00a0 ~200 umol photons
s-1 m-2. The cultures were grown under a 12:10 light:dark cycle and mixed by
hand twice per day. Sampling occurred once per day, just before the beginning
of the dark period. The media was designed to assess the carbon partitioning
response under stress from Si, N, and both Si & N. To allow better comparison
among species and treatments, all experimental flasks were started with a ~40
umol L-1 initial nitrate concentration. In those treatments limited by silicic
acid (and therefore replete in N), the Si concentration was adjusted to
produce the same number of replete cells as the N-stress treatments.
Phosphorous was added in sufficient quantities to avoid P depletion; vitamins
and trace metals were added at f/20 and f/80 concentrations, respectively.
Thalassiosira weissflogii:
Duplicate batch cultures of coastal diatom strain Thalassiosira weissflogii
(CCMP 1051) were grown in clear rectangular 20L polycarbonate carboys under
six cool white and two natural s11 type light bulbs providing\\u00a0 ~200 umol
photons s-1 m-2. The cultures were grown under a 12:10 light:dark cycle and
mixed by hand twice per day. Sampling occurred once per day, just before the
beginning of the dark period. The media was designed to assess the carbon
partitioning response under stress from Si, N, and both Si & N. To allow
better comparison among species and treatments, all experimental flasks were
started with a ~40 umol L-1 initial nitrate concentration. In those treatments
limited by silicic acid (and therefore replete in N), the Si concentration was
adjusted to produce the same number of replete cells as the N-stress
treatments. Phosphorous was added in sufficient quantities to remain replete
throughout the duration of each experiment; vitamins and trace metals were
added at f/20 and f/80 concentrations, respectively.
Odontella aurita:
Duplicate batch cultures of coastal diatom strain Odontella aurita (CCMP
595) was grown in clear rectangular 20L polycarbonate carboys under six cool
white and two natural s11 type light bulbs providing\\u00a0 ~200 umol photons
s-1 m-2. The cultures were grown under a 12:10 light:dark cycle and mixed by

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.

"From http://www.lternet.edu/sites/sbc
The Santa Barbara Coastal LTER is located in the coastal zone of southern California near Santa Barbara. It is bounded by the steep east-west trending Santa Ynez Mountains and coastal plain to the north and the unique Northern Channel Islands archipelago to the south. Santa Barbara Coastal Long-Term Ecological Research (SBC) Project is headquartered at the University of California, Santa Barbara, and is part of the National Science Foundation’s (NSF) Long-Term Ecological Research (LTER) Network.
The research focus of SBC LTER is on ecological systems at the land-ocean margin. Although there is increasing concern about the impacts of human activities on coastal watersheds and nearshore marine environments, there have been few long-term studies of the linkages among oceanic, reef, sandy beaches, wetland, and upland habitats. SBC LTER is helping to fill this gap by studying the effects of oceanic and coastal watershed influences on kelp forests in the Santa Barbara Channel located off the coast of southern California. The primary research objective of SBC LTER is to investigate the relative importance of land vs. ocean processes in structuring giant kelp (Macrocystis pyrifera) forest ecosystems for different conditions of land use, climate and ocean influences.
SBC LTER Data: The Santa Barbara Coastal (SBC) LTER data are managed by and available directly from the SBC project data site URL shown above. If there are any datasets listed below, they are data sets that were collected at or near the SBC LTER sampling locations, and funded by NSF OCE as ancillary projects related to the SBC LTER core research themes.

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.
