attribute NC_GLOBAL acquisition_description String S. marinoi experimental design:  \n DOM was harvested from cultures of S. marinoi 48 hours after the indicated\nnutrient became deplete. Harvested media was 2x filtered through 0.2 um\nfilters. Ambient seawater was the aged seawater media in which the\nphytoplankton were grown. Media (6L) and inoculum (2L, 1.2-um filtered water\nfrom the Santa Barbara Channel) were combined in a spigoted polycarbonate\ncarboy and incubated in the dark at 14C for 4 months.\n \nC. socialis experimental design:  \n DOM was harvested from cultures of C. socialis 48 hours after the indicated\nnutrient became deplete. Harvested media was 2x filtered through 0.2 um\nfilters. Ambient seawater was the aged seawater media in which the\nphytoplankton were grown. Media (6L) and inoculum (2L, 1.2-um filtered water\nfrom the Santa Barbara Channel) were combined in a spigoted polycarbonate\ncarboy and incubated in the dark at 14C for 4 months.\n \nT. weissflogii experimental design:  \n DOM was harvested from cultures of T. weissflogii 48 hours after the\nindicated nutrient became deplete. Harvested media was 2x filtered through 0.2\num filters. Ambient seawater was the aged seawater media in which the\nphytoplankton were grown. Media (6L) and inoculum (2L, 1.2-um filtered water\nfrom the Santa Barbara Channel) were combined in a spigoted polycarbonate\ncarboy and incubated in the dark at 14C for 4 months.\n \nO. aurita experimental design:  \n DOM was harvested from cultures of O. aurita 48 hours after the indicated\nnutrient became deplete. Harvested media was 2x filtered through 0.2 um\nfilters. Ambient seawater was the aged seawater media in which the\nphytoplankton were grown. This experiment included full-volume inorganic\nnutrient controls (ambient seawater with added nitrate and phosphate or\nsilicate and phosphate, at concentrations comparable to the Si-limited and\nN-limited treatments, respectively) and small-volume (2L, same media:inoculum\nratio) controls to look at carry-over from the phytoplankton media that were\nsampled less frequently and with fewer replicates (ambient seawater plus f/2\nand ambient seawater plus filtered media from an O. aurita culture in\nexponential growth, both at concentrations comparable to those at the start of\nthe O. aurita batch culture grow-ups). Media (6L) and inoculum (2L, 1.2-um\nfiltered water from the Santa Barbara Channel) were combined in a spigoted\npolycarbonate carboy and incubated in the dark at 14C for 4 months.

Data are restricted until June 2016.

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.\nWe 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:\n1) We will investigate how limitation by either N or Si impacts the quantity and chemical composition of the DOM released by diatoms.\n2) 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.\n3) Predicted DOM dynamics based on (1) and (2) will be tested in the field during diatom blooms in the Santa Barbara Channel, California.\nWhile 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.\nReferences:\nLancelot, C.

attribute NC_GLOBAL projects_1_description String From http://www.lternet.edu/sites/sbc\nThe 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.\nThe 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.\nSBC 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. See the SBC LTER Data Overview page for access to data and information about data management policies.

attribute NC_GLOBAL summary String Culture studies of diatoms that dominate spring blooms in the Santa Barbara Channel were used to examine the effects of N and Si stress on the magnitude of production and the chemical composition of DOM (see the BIB Experiments dataset). The ability of natural assemblages of bacteria to utilize DOM produced under Si and N limitation was then assessed using remineralization experiments. Species examined in the remineralization experiments include: Skeletonema marinoi, Chaetoceros socialis, Thalassiosira weissflogii, and Odontella aurita.
