The collected data uses a consistent methodology for primary production, using the uptake of inorganic 14C through photosynthesis, in incubations carried out in situ.&lt;br /&gt; &lt;br /&gt; The primary support for this dataset was the National Aeronautic and Space Administration grant&amp;nbsp;NNX14AM15G (P.I.: Z.-P. Lee).&lt;/p&gt; Methods and Sampling: &lt;p&gt;Carbon assimilation was measured from the uptake 14C into particulate matter as an estimate of primary production (see Barber et al., 2001). Two replicate samples (in polysulfone tissue culture flasks or polycarbonate bottles) retrieved from eight depths in the euphotic zone were suspended from a spar buoy, floating free of the ship, from dawn until dusk. See Barber et al. (2001).&lt;/p&gt; &lt;p&gt;Phytoplankton absorption procedure followed that described in Mueller and Austin (1995). Two liters of water were collected onto GF/F filters and scanned over 400-700 nm in a Perkin-Elmer Lambda-3 spectrophotometer. The detrital spectrum was similarly scanned after an extraction in hot methanol and the phytoplankton pigment spectrum (aph, aphw) found by difference. The pathlength amplification (beta-correction) factors were determined for the Lambda-3, prior to the cruises, based on a composite of 12 different cultures of phytoplankton. See Marra et al. (2000).&lt;/p&gt; &lt;p&gt;HPLC methods for pigments varied over time. References are Trees et al. (2000), Bidigare et al. (1990), Latasa and Bidigare (1998), and Goericke and Repeta (1993).&lt;/p&gt; &lt;p&gt;PAR sensors (model QSP-200, Biospherical Instruments San Diego, CA), were used in a self- contained PAR-sensing and data-logging unit. Spectral irradiance (“irradiance” in the dataset) was measured using a Marine Environmental Recorder (MER) model 2040 (Biospherical Instruments) from which PAR was calculated. See Marra et al. (2000).&lt;/p&gt; &lt;p&gt;Methods for nutrient concentrations followed JGOFS protocols (see Barber et al., 2001).&lt;/p&gt; &lt;p&gt;Sampling and analytical procedures: The samples were subsequently filtered through GF/F filters, and the filters assayed for their radioactivity by liquid scintillation counting aboard ship. In the database,the primary production values are presented as the mean of the two replicate samples.&amp;nbsp;&lt;/p&gt; Funding provided by National Aeronautics & Space Administration (NASA) Award Number: NNX14AM15G Award URL: https://www.nssc.nasa.gov/grantstatus Funding provided by Office of Naval Research (ONR) Award Number: N00014-86-K-0204 Funding provided by NSF Division of Ocean Sciences (NSF OCE) Award Number: OCE-9312355 Award URL: https://www.nsf.gov/awardsearch/show-award?AWD_ID=9312355 Funding provided by NSF Division of Ocean Sciences (NSF OCE) Award Number: OCE-9311255 Award URL: https://www.nsf.gov/awardsearch/show-award?AWD_ID=9311255 Funding provided by NSF Division of Ocean Sciences (NSF OCE) Award Number: OCE-9311244 Award URL: https://www.nsf.gov/awardsearch/show-award?AWD_ID=9311244 Funding provided by NSF Division of Ocean Sciences (NSF OCE) Award Number: OCE-9311312 Award URL: https://www.nsf.gov/awardsearch/show-award?AWD_ID=9311312 Funding provided by Office of Naval Research (ONR) Award Number: N00014-81-C-0062 Funding provided by NSF Division of Ocean Sciences (NSF OCE) Award Number: OCE-8817515 Award URL: https://www.nsf.gov/awardsearch/show-award?AWD_ID=8817515 Funding provided by NSF Division of Ocean Sciences (NSF OCE) Award Number: OCE-8121011 Award URL: https://www.nsf.gov/awardsearch/show-award?AWD_ID=8121011 Funding provided by NSF Office of Polar Programs (formerly NSF PLR) (NSF OPP) Award Number: OPP-9530611 Award URL: https://www.nsf.gov/awardsearch/show-award?AWD_ID=9530611 Funding provided by NSF Division of Ocean Sciences (NSF OCE) Award Number: OCE-8120773 Award URL: https://www.nsf.gov/awardsearch/show-award?AWD_ID=8120773 Funding provided by NSF Office of Polar Programs (formerly NSF PLR) (NSF OPP) Award Number: OPP-9531990 Award URL: https://www.nsf.gov/awardsearch/show-award?AWD_ID=8120773 Funding provided by NSF Office of Polar Programs (formerly NSF PLR) (NSF OPP) Award Number: OPP-9531981 Award URL: https://www.nsf.gov/awardsearch/show-award?AWD_ID=9531981 Funding provided by Office of Naval Research (ONR) Award Number: N00014-89-J-1150 Funding provided by Office of Naval Research (ONR) Award Number: NO0014-87-K-0160 Funding provided by Office of Naval Research (ONR) Award Number: NO0014-89-J-1160 Funding provided by Office of Naval Research (ONR) Award Number: NO0014-94-L-0394 Funding provided by National Aeronautics & Space Administration (NASA) Award Number: NNX14AQ47A Award URL: https://cce.nasa.gov/cgi-bin/cce/cce_profile.pl?project_group_id=3266 completed John F.

The overall program goals are to promote, plan, and coordinate collaborative, multidisciplinary research opportunities within the U.S. research community and with international partners. Important OCB-related activities currently include: the Ocean Carbon and Climate Change (OCCC) and the North American Carbon Program (NACP); U.S. contributions to IMBER, SOLAS, CARBOOCEAN; and numerous U.S. single-investigator and medium-size research projects funded by U.S. federal agencies including NASA, NOAA, and NSF. The scientific mission of OCB is to study the evolving role of the ocean in the global carbon cycle, in the face of environmental variability and change through studies of marine biogeochemical cycles and associated ecosystems. The overarching OCB science themes include improved understanding and prediction of: 1) oceanic uptake and release of atmospheric CO2 and other greenhouse gases and 2) environmental sensitivities of biogeochemical cycles, marine ecosystems, and interactions between the two. The OCB Research Priorities (updated January 2012) include: ocean acidification; terrestrial/coastal carbon fluxes and exchanges; climate sensitivities of and change in ecosystem structure and associated impacts on biogeochemical cycles; mesopelagic ecological and biogeochemical interactions; benthic-pelagic feedbacks on biogeochemical cycles; ocean carbon uptake and storage; and expanding low-oxygen conditions in the coastal and open oceans.

The U.S. JGOFS AESOPS program focused on two regions in the Southern Ocean: an east/west section of the Ross-Sea continental shelf along 76.5°S, and a second north/south section of the Southern Ocean spanning the Antarctic Circumpolar Current (ACC) at ~170°W (identified as the Polar Front). The science program, coordinated by Antarctic Support Associates (ASA), comprised eleven cruises using the R.V.I.B Nathaniel B. Palmer and R/V Roger Revelle as observational platforms and for deployment and recovery of instrumented moorings and sediment-trap arrays. The Ross-Sea region was occupied on six occasions and the Polar Front five times. Mapping data were obtained from SeaSoar, ADCP, and bathymetric systems.

One reason that primary production is little known is the lack of<br /> understanding of the geographical and temporal variability in phytoplankton physiology.<br /> For example it is only recently that the importance has been revealed, of the<br /> so-called photoprotectant pigments, pigments that, in effect, shield the photosynthetic<br /> apparatus from too much sunlight. This project will investigate the geographic and<br /> temporal variability of a fundamental property of oceanic photosynthesis: the quantum<br /> yield, or the ratio of the available light to the amount of carbon fixed in photosynthesis.<br /> The PIs propose an hypothesis based on earlier measurements, that in the lower parts<br /> of the euphotic zone in the stratified ocean, the upward flux of nutrients regulates<br /> the value of the quantum yield, while in the upper parts, irradiance governs its value,<br /> through the pigment composition of the phytoplankton. This hypothesis will be tested<br /> by making estimates of the quantum yield's maximum value through very careful and<br /> comprehensive measurements of the bio-optical properties and species composition of<br /> the phytoplankton, as well as the submarine light environment, hydrography, and nutrients.<br /> These measurements will be along both temporal and spatial gradients in the ocean to<br /> create the basis for environmental regulation of quantum yield. These measurements will<br /> be used to establish precisely how the maximum value of the quantum yield is regulated<br /> by solar flux and plant nutrients. This research provides a mechanism to understand<br /> how the processes of nutrient supply and light affect the physiology of natural populations<br /> of phytoplankton, a long-standing problem in biological oceanography. It also provides a<br /> means for improving the modeling primary productivity, including estimating productivity<br /> in the global ocean from space.</p> ON DEQUE largerWorkCitation project Development of new solar radiation and primary production products from MODIS ocean-color measurements https://osprey.bco-dmo.org/project/783328 Development of new solar radiation and primary production products from MODIS ocean-color measurements <p>The present MODIS standard products for the oceans include the above-surface photosynthetic available radiation (PAR(0+)) and the diffuse attenuation coefficient at 490 nm (Kd(490)). They are valuable for many studies, but are not adequate for the estimation of solar radiation in the upper water column. This is mainly because: 1) the transmittance of light from above surface to below surface is not a constant, but varies with location and time; 2) Kd(490), a single wavelength product, cannot be used to calculate the vertical attenuation of PAR (a broad band product); and 3) PAR(0+) represents daily total radiation, while Kd(490) (and the evaluation Kd(PAR) product) represents an instantaneous attenuation. Because the light attenuation coefficient also varies diurnally, a combination of daily PAR(0+) and instantaneous Kd(PAR) will result in significant (can be a factor of 2 or 3, as it is depth dependent) errors in the estimated PAR at depth.</p> <p>Separately, the primary production (PP) values of the global oceans estimated from the traditional chlorophyll-based approaches contain significant uncertainties, which make the current satellite-derived water-column PP unreliable for the assessment of spatial and temporal variations. Mainly the uncertainty arises from the large spatial and temporal variation of chlorophyll-specific absorption coefficient (a*ph), which is required, explicitly or implicitly, for the retrieval of chlorophyll-a concentration from water color and for the estimation of biomass-normalized photosynthetic efficiency. It has long been argued that it is necessary to take an approach that estimates PP without the engagement of a*ph.</p> <p>To overcome the limitations listed above, and more importantly to maximize the value offered by MODIS Terra/Aqua for ocean physical and biogeochemical studies, we will develop and refine new algorithms for the generation of these new products from MODIS ocean-color measurements: 1) sub-surface, daily, usable solar radiation (USR), 2) diffuse attenuation coefficient of USR (K(USR)), and 3) daily, water-column primary production (PPeu). USR is defined as the solar radiation in the spectral window of 400-560 nm, a window that penetrates most in the global oceans and is most significant for phytoplankton photosynthesis. Because USR and K(USR) products are consistent both spectrally and temporally, it will then be straightforward, and accurate, to estimate solar radiation at depths when the values of K(USR) and subsurface USR are known. Further, the proposed PPeu estimation will be based on the 'first principles of phytoplankton photophysiology and light penetration' [Behrenfeld 1998], i.e., it will use directly the absorption coefficient of phytoplankton for the estimation of absorbed photons, thus by-passing the engagement of a*ph when using chlorophyll concentration. The resulted PP products will then significantly improve the spatial and temporal characterizations of PPeu in the global oceans.</p> <p>Completion of this project will not only result in innovative products directly applicable to studies of the ocean's heat budget and photosynthesis in the upper water column, but will also be important for investigating photo-oxidation and phytoplankton phenology. The project will further enhance our capabilities in meeting NASA Strategic Sub-goal 3A 'to study Earth from space to advance scientific understanding and meet societal needs'.</p> ISPP14C largerWorkCitation project ARLINDO Circulation, A Study of the Indonesian Ocean Circulation and Mixing https://www.ldeo.columbia.edu/res/fac/physocean/Arlindo/ ARLINDO Circulation, A Study of the Indonesian Ocean Circulation and Mixing <p>9529648 Gordon In this project, the PI will carry out phase 2 of ARLINDO (Indonesian acronym for Indonesian Throughflow), called ARLINDO Circulation (AC).

The Arabian Sea is a low latitude oceanic region with strong and reversing monsoon winds together with relatively modest seasonal variability in solar radiation and sea surface temperature. The strong episodic wind forcing is accompanied by large changes in nutrients and massive phytoplankton blooms with high primary productivity. The objectives of the project are to 1) determine the seasonal and spatial pattern of variability of primary production using in situ and deck incubations in order to understand the processes that control both total production and export production; 2) determine the seasonal and spatial pattern of the photosynthetic parameters incubations to understand the effect of environmental covariables such as nutrients on these parameters; and 3) use the newly determined photosynthetic parameters in bio-optical models to improve estimates of primary production and compare these model estimates with our direct observations of primary production.</p> <p>MARRA 9311255 This proposal is a continuing effort of to collect and process data on optics and pigment distribution by combining the efforts of JGOFS and the Word Ocean Circulation Experiment (WOCE) Hydrographic Program (WHP). The program will operate a bio-optical profiler to collect data on the biological and optical properties of the upper water column. Data to collected include spectral irradiance (7 channels each of upwelling and downwelling ), broad-band visible irradiance (PAR), fluorescence, and beam transmission. This is perhaps the first undertaking of a systematic and consistent data collection on the oceans pigment and optical properties, and would be invaluable in improving algorithms for satellite imaging of ocean pigments and in estimating primary production.</p> Arabian Sea Primary Prod largerWorkCitation project U.S. JGOFS: Response of Arabian Sea Phytoplankton Biomass, Pigmentation, Growth Rates, and Community Structure To Seasonally Varying Physically Forcing https://osprey.bco-dmo.org/project/814850 U.S. JGOFS: Response of Arabian Sea Phytoplankton Biomass, Pigmentation, Growth Rates, and Community Structure To Seasonally Varying Physically Forcing <p>9311244 Goericke The U.S. Arabian Sea JGOFS program offers the unique opportunity to study the response of an oceanic ecosystem to strong and seasonally predictable physical forcing in an environment with strong spatial gradients. Biological conditions in the Arabian Sea vary from extreme oligotrophy to extreme eutrophy. Primary production and concentrations of chlorophyll a, for example, change by one to two orders of magnitude over space and time. We propose to study the effects of the seasonally varying physical forcing on the phytoplankton community as a whole and on individual populations of microalgae, using primarily pigment-based methods. We will test the hypothesis, suggested by data from other environments, that phytoplankton community structure and growth rates during most of the year. The exception is the area off Oman during the SW monsoon when oceanic upwelling occurs. At this time the community is expected to be dominated by diatoms growing at high rates. Phytoplankton community structure will be monitored by measuring the concentration of taxon-specific chlorophylls and carotenoids by high-pressure liquid chromatography. It is proposed to carry out these analyses as part of the JGOFS core measurements. Using the pigment 14c-labeling method we propose to measure phytoplankton carbon-biomass, phytoplankton growth rates and taxon-specific growth rates to study the physiological response of the phytoplankton community to the seasonally varying physical forcing. Carbon to Chl a ratios will be calculated from phytoplankton biomass and chl a and used to calculated seasonal maps of phytoplankton carbon-biomass for the Arabian Sea from remotely sensed ocean and biomass will allow us to determine factors which control the growth and abundance of the individual phytoplankton population, such as coccolithophores or prochlorophytes, and their contribution to carbon cycling in this environment.</p> Arabian Sea Phyto Seasonality largerWorkCitation project Photo-Ecological Investigations in the Arabian Sea https://osprey.bco-dmo.org/project/814858 Photo-Ecological Investigations in the Arabian Sea <p>9311312 BIDIGARE The northern Arabian Sea exhibits regular, predictable oscillations in phytoplankton biomass and production driven by monsoonal atmospheric forcing. In this project, the principal investigator will characterize phytoplankton pigment distributions during the Arabian Sea Process Study (ASPS) using state-of-the-art high- performance liquid chromatography (HLPC) methods. There are four major research objectives. Seasonal and spatial pigment data will be used (1) to document phytoplankton biomass (as chlorophyll-a) and species composition of pigments and other variables and (4) use the model to estimate time-and-depth-dependent rates of primary production. This work will complement the efforts of other ASPS investigators studying phytoplankton dynamics both by water column sampling and via satellite imagery.</p> Arabian Sea Photo-Ecology largerWorkCitation project Biowatt Experiment: Bioluminescence and Optical Variability of the Sea (Biowatt I) http://uop.whoi.edu/projects/biowatt/biowatt.html Biowatt Experiment: Bioluminescence and Optical Variability of the Sea (Biowatt I) Biowatt I largerWorkCitation project Piimary Production Measurements for the 20-West Program (NABE) https://osprey.bco-dmo.org/project/814989 Piimary Production Measurements for the 20-West Program (NABE) <p>The Joint Global Ocean Flux Study (JGOFS) of the spring bloom in the North Atlantic will begin in 1989.

The 1991 field program took place from April 30 to September 6 and included a central surface mooring to document the temporal evolution of physical, biological, and optical properties. In this paper we describe the physical variability observed at the 1991 mooring site, concentrating on the vertical structure of temperature and velocity in the upper 300 m of the water column and their changes in response to heat and momentum fluxes at the sea surface. The deployment period included the spring transition, when upper ocean re stratification was initiated after deep winter mixing, and the fall transition, when mixed layer deepening began again. The dominant signal in temperature was seasonal variation, with a 6°C increase observed at the sea surface from May to August. Prior to development of the seasonal stratification, a period dominated by near-surface temperature variability was observed in association with a 15-day mean flux of only 20 W m−2 into the ocean. Pronounced day/night oscillations of heat flux during this period resulted in alternating development and destruction of stratification and intense diurnal cycling of the mixed layer depth. A qualitative comparison of the observed temperature structure to the prediction of a one-dimensional mixed layer model showed that local processes dominated during the initiation of restratification and during most of the summer warming period. Nonlocal processes were important after the fall transition</p> ML-ML largerWorkCitation project Upgrade the KD(490) product to the normalized diffuse attenuation coefficient at 490 nm (NKD(490)) for SUOMI NPP https://osprey.bco-dmo.org/project/815084 Upgrade the KD(490) product to the normalized diffuse attenuation coefficient at 490 nm (NKD(490)) for SUOMI NPP <p>The diffuse attenuation coefficient at 490 nm, Kd(490), is one of the standard ocean data products of the Earth Observing System (EOS), which represents an important component of the Earth Data Records (EDR). Traditionally, and even today, its derivation from satellite ocean color measurements takes the same approach as that for producing chlorophyll-a concentration ([Chl]), i.e. using the blue-green ratios of remote- sensing reflectance (Rrs) as the sole input to empirically generate the desired product. Such an approach is generally appropriate for deriving [Chl] in oceanic (or Case-1) waters, but is subject to inherent ambiguity and errors for Kd(490) for both oceanic and coastal waters. This is because that the diffuse attenuation coefficient is an apparent optical property, i.e. it varies with sun angle, while [Chl] does not. We propose to upgrade this attenuation product from two aspects: 1) remove the sun-angle related ambiguity, and 2) improve data quality through a retrieval system based on the radiative transfer theory. To achieve this upgrade, we propose to generate the normalized diffuse attenuation coefficient at 490 nm, nKd(490), from the Rrs products provided by Suomi NPP VIIRS. nKd(490) is defined as the diffuse attenuation coefficient for the Sun at zenith with a black sky, which matches the definition of the normalized water-leaving radiance (nLw) for satellite ocean color missions. This nKd(490) product is thus not only clear in its representation, but also facilitates its evaluation with field measurements. In addition, because nKd(490) will be produced through a mechanistic system rooted in the radiative transfer theory, this product will have higher science quality for the global oceans, in particular for turbid coastal waters. Furthermore, because the semi-analytical system takes a step-wise approach for the calculation of nKd(490), an uncertainty map of the nKd(490) product will also be generated via the error-propagation theory. The results from this effort will provide data products important not only to support the decadal continuity of the EDR, but also to study Earth from space to advance scientific understanding and meet societal needs.</p> KD490 Upgrade largerWorkCitation project eng; USA oceans U.S. JGOFS North Atlantic; Sargasso Sea (western North Atlantic Ocean), south of Bermuda, BATS area and Hydrostation "S"; U.S. JGOFS Southern Ocean; U.S. JGOFS Arabian Sea; N.

download onLine dataset &lt;p&gt;Carbon assimilation was measured from the uptake 14C into particulate matter as an estimate of primary production (see Barber et al., 2001). Two replicate samples (in polysulfone tissue culture flasks or polycarbonate bottles) retrieved from eight depths in the euphotic zone were suspended from a spar buoy, floating free of the ship, from dawn until dusk. See Barber et al. (2001).&lt;/p&gt; &lt;p&gt;Phytoplankton absorption procedure followed that described in Mueller and Austin (1995). Two liters of water were collected onto GF/F filters and scanned over 400-700 nm in a Perkin-Elmer Lambda-3 spectrophotometer. The detrital spectrum was similarly scanned after an extraction in hot methanol and the phytoplankton pigment spectrum (aph, aphw) found by difference. The pathlength amplification (beta-correction) factors were determined for the Lambda-3, prior to the cruises, based on a composite of 12 different cultures of phytoplankton. See Marra et al. (2000).&lt;/p&gt; &lt;p&gt;HPLC methods for pigments varied over time. References are Trees et al. (2000), Bidigare et al. (1990), Latasa and Bidigare (1998), and Goericke and Repeta (1993).&lt;/p&gt; &lt;p&gt;PAR sensors (model QSP-200, Biospherical Instruments San Diego, CA), were used in a self- contained PAR-sensing and data-logging unit. Spectral irradiance (“irradiance” in the dataset) was measured using a Marine Environmental Recorder (MER) model 2040 (Biospherical Instruments) from which PAR was calculated. See Marra et al. (2000).&lt;/p&gt; &lt;p&gt;Methods for nutrient concentrations followed JGOFS protocols (see Barber et al., 2001).&lt;/p&gt; &lt;p&gt;Sampling and analytical procedures: The samples were subsequently filtered through GF/F filters, and the filters assayed for their radioactivity by liquid scintillation counting aboard ship. In the database,the primary production values are presented as the mean of the two replicate samples.&amp;nbsp;&lt;/p&gt; Specified by the Principal Investigator(s) &lt;p&gt;&lt;strong&gt;BCO-DMO Processing Notes:&lt;/strong&gt;&lt;br /&gt; - added conventional header with dataset name, PI name, version date&lt;br /&gt; - modified parameter names to conform with BCO-DMO naming conventions&lt;br /&gt; - re-formatted dates from m/d/yy&amp;nbsp;to yyyy-mm-dd&lt;br /&gt; - NaN and blank values were replaced with no data value 'nd'&lt;/p&gt; Specified by the Principal Investigator(s) asNeeded 7.x-1.1 Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact model QSP-200, Biospherical Instruments San Diego, CA model QSP-200, Biospherical Instruments San Diego, CA PI Supplied Instrument Name: model QSP-200, Biospherical Instruments San Diego, CA PI Supplied Instrument Description:For light measurement Instrument Name: Biospherical QSP-200L underwater PAR Sensor Instrument Short Name:QSP-200L underwater PAR Instrument Description: Underwater radiometer with a PAR spectral response (400-700nm).

HPLC instruments consist of a reservoir of the mobile phase, a pump, an injector, a separation column, and a detector. Compounds are separated by high pressure pumping of the sample mixture onto a column packed with microspheres coated with the stationary phase. The different components in the mixture pass through the column at different rates due to differences in their partitioning behavior between the mobile liquid phase and the stationary phase.
