Samples were collected for particulates and dissolved constituents. Determinations of phytoplankton productivity were made using 14C, 15NO3 and 32Si incorporation using on-deck incubator. Measurements of microbial activity, biomass and DNA. 3H-Leucine were used to assess bacterial production. Deck board incubation experiments were also conducted. The Triaxus survey was used to assess fluorescence and to target the areas of water collection for experimental work. A 24-station CTD grid was performed on each cruise. A full suite of particulate and dissolved nutrients were measured, along with bacterial and phytoplankton productivity measurements. Two large incubation experiments were conducted onboard using deck incubators.\\u00a0 Assays of nutrient stress: Phytoplankton nutrient stress at each grid station were quantified by measuring the uptake rate of silicic acid and nitrate at the ambient concentration and then again after the addition of a saturating level of the nutrient. Tracers, 15NO3 or 32Si(OH)4, were added to replicate subsamples. One of the subsamples was unaltered to yield the rate of nitrate or Si uptake under ambient nutrient concentrations. The second sample in each pair received a saturating addition of the nutrient whose uptake was being monitored, yielding the uptake rate under conditions of nutrient sufficiency. Isotopic 14C tracer experiments: The methods of Lancelot and Mathot (1985) were modified to track primary production (PP), dissolved organic Carbon (DOC) extracellular release, fraction of released DOC incorporated by bacterioplankton and the fraction that\\u2019s resistant to rapid remineralization."; String awards_0_award_nid "54995"; String awards_0_award_number "OCE-0850857"; String awards_0_data_url "http://www.nsf.gov/awardsearch/showAward.do?AwardNumber=0850857"; String awards_0_funder_name "NSF Division of Ocean Sciences"; String awards_0_funding_acronym "NSF OCE"; String awards_0_funding_source_nid "355"; String awards_0_program_manager "David L.

Precision is dramatically increased when FIA is used instead of manual injections and as a result very specific FIA systems have been developed for a wide array of analytical techniques."; String instruments_1_instrument_external_identifier "https://vocab.nerc.ac.uk/collection/L05/current/LAB36/"; String instruments_1_instrument_name "Flow Injection Analyzer"; String instruments_1_instrument_nid "657"; String instruments_1_supplied_name "flow injection autoanalyzer"; String keywords "active, activity, altimetry, ammonia, ammonium, autofluor, autofluor_cells, available, bact, bact_prod, bact_prod_cells, bact_prod_light, bact_prod_light_cells, bco, bco-dmo, beam, beam_c, biological, bot, bottle, c14, C14_dark, C14_light, C14_prod, carbon, cast, cast_type, cells, chemical, chemistry, chl, chl_a, chlorophyll, collection, collection_bot_ID, commerce, concentration, concentration_of_chlorophyll_in_sea_water, cond, cond2, corrected, cruise, cruise_id, cruise_name, dark, data, dataset, date, date_gmt, date_local, decimal, decimal_year_gmt, decimal_year_local, department, depth, depth_actual, depth_bottom, depth_ctd, depth_target, dmo, doc, don, downwelling, downwelling_photosynthetic_photon_radiance_in_sea_water, earth, Earth Science > Oceans > Ocean Chemistry > Ammonia, Earth Science > Oceans > Ocean Chemistry > Chlorophyll, Earth Science > Oceans > Ocean Chemistry > Nitrate, Earth Science > Oceans > Ocean Chemistry > Phosphate, Earth Science > Oceans > Ocean Chemistry > Silicate, Earth Science > Oceans > Ocean Optics > Photosynthetically Active Radiation, Earth Science > Oceans > Ocean Optics > Radiance, enriched, erddap, erho, evb, event, fluor, iso, krho, kvb, laboratory, latitude, light, local, longitude, management, mass, mass_concentration_of_phosphate_in_sea_water, mass_concentration_of_silicate_in_sea_water, mole, mole_concentration_of_ammonium_in_sea_water, mole_concentration_of_nitrate_in_sea_water, mole_concentration_of_nitrite_in_sea_water, n02, n15, N15_enriched_rho, N15_enriched_Vb, N15_rho, N15_Vb, name, nh4, nitrate, nitrite, NO2, no3, NO3_NO2, O2, O2_umol_kg, ocean, oceanography, oceans, office, optics, organic, oxygen, par, PAR_corrected, particulate, per, phaeo, phosphate, photon, photosynthetic, photosynthetically, po4, POC, pon, preliminary, press, prod, radiance, radiation, rho, sal, sal2, sample, satellite, science, sea, seawater, si32, Si32_Erho, Si32_EVb, Si32_Krho, Si32_KVb, Si32_rho, Si32_Vb, Si_bio, sigma, sigma_0, sigma_0_2, silicate, spar, sta, sta_id, temp2, temperature, time, time_gmt, time_local, tot, tot_bact_cells, tot_chl, trans, type, umol, water, year"; String keywords_vocabulary "GCMD Science Keywords"; String license "https://www.bco-dmo.org/dataset/517839/license"; String metadata_source "https://www.bco-dmo.org/api/dataset/517839"; Float64 Northernmost_Northing 34.4314; String param_mapping "{'517839': {'lat': 'master - latitude', 'lon': 'master - longitude', 'depth_actual': 'master - depth'}}"; String parameter_source "https://www.bco-dmo.org/mapserver/dataset/517839/parameters"; String people_0_affiliation "University of California-Santa Barbara"; String people_0_affiliation_acronym "UCSB-MSI"; String people_0_person_name "Craig Carlson"; String people_0_person_nid "50575"; String people_0_role "Lead Principal Investigator"; String people_0_role_type "originator"; String people_1_affiliation "University of California-Santa Barbara"; String people_1_affiliation_acronym "UCSB-MSI"; String people_1_person_name "Mark A.

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.

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.
