DatasetVERTIGO project Sediment Trap Fluxes of mass, elements and phytoplankton pigments data from KM0414 and RR_K2 cruises(Biological and Chemical Oceanography Data Management Office (BCO-DMO). Contact: bco-dmo-data@whoi.edu, 2010-12-01) Lamborg, Carl H. ; Buesseler, Ken O.The main goal of VERTIGO is the investigation of the mechanisms that control the efficiency of particle transport through the mesopelagic portion of the water column. Question: What controls the efficiency of particle transport between the surface and deep ocean? More specifically, what is the fate of sinking particles leaving the upper ocean and what factors influence remineralization length scales for different sinking particle classes? VERTIGO researchers have set out to test two basic hypotheses regarding remineralization control, namely: 1. particle source characteristics are the dominant control on the efficiency of particle transport; and/or that 2. mid-water processing, either by zooplankton or bacteria, controls transport efficiency. To test their hypotheses, they will conduct process studies in the field focused on particle flux and composition changes in the upper 500-1000m of the ocean. The basic approach is to examine changes in particle composition and flux with depth within a given source region using a combination of approaches, many of which are new to the field. These include neutrally buoyant sediment traps, particle pumps, settling columns and respiration chambers, along with the development of new biological and geochemical tools for an integrated biogeochemical assessment of the biological pump. Three week process study cruises have been planned at two sites - the Hawaii Ocean Time-series site (HOT) and a new moored time-series site in the subarctic NW Pacific (Japanese site K2; 47°N 160°E) - where there are strong contrasts in rates of production, export, particle composition and expected remineralization length scales. Evidence for variability in the flux vs. depth relationship of sinking particles is not in dispute but the controls on particle transport efficiency through the twilight zone remain poorly understood. A lack of reliable flux and particle characterization data within the twilight zone has hampered our ability to make progress in this area, and no single approach is likely to resolve these issues. The proposed study will apply quantitative modeling to determine the net effects of the individual particle processes on the effective transport of carbon and other elements, and to place the shipboard observations in the context of spatial and temporal variations in these processes. For rapid progress in this area, we have organized this effort as a group proposal taking advantage of expertise in the US and international community. The efficiency of particle transport is important for an accurate assessment of the ocean C sink. Globally, the magnitude and efficiency of the biological pump will in part modulate levels of atmospheric CO2. We maintain that to understand present day ocean C sequestration and to evaluate potential strategies for enhancing sequestration, we need to assess possible changes in the efficiency of particle transport due to climate variability or via purposeful manipulations of C uptake, such as via iron fertilization.

DatasetMesozooplankton biomass estimates from MOCNESS tows collected from R/V Oceanus cruises : OC415-01, OC415-03, OC404-01 and OC404-04 from the Sargasso Sea from June 14, 2004 to August 24, 2005 (EDDIES project)(Biological and Chemical Oceanography Data Management Office (BCO-DMO). Contact: bco-dmo-data@whoi.edu, 2011-10-13) Steinberg, Deborah K. ; Goldthwait, Sarah A.The Eddies Dynamics, Mixing, Export, and Species composition (EDDIES) mesozooplankton biomass data set includes estimates of mesozooplankton biomass determined from MOCNESS plankton net tows. Zooplankton biomass estimates were determined from 1 m^2, 150 micron mesh MOCNESS (Multiple Opening/Closing Net and Environmental Sensing System) tows. The following discrete depth intervals were sampled on the upcast: 0-50, 50-100, 100-150, 150-200, 200-300, 300-400, 400-500, 500-600, and 600-700 m. Generally paired tows during the day (9:30-15:00 local time) and night (21:30-03:00) were performed at each station. A single tow generally covered 5-15 km. The nominal position (lat_n and lon_n) for each tow is the position at the mid depth 200-300m sampling interval. Table 1 (pg 1362) of Goldthwait and Steinberg (2008) is a sequential list of all MOCNESS mesozooplankton tows and includes eddy identification number and location. Each sample was size-fractionated using nested sieves of 0.15 mm, 0.5 mm, 1 mm, 2mm, and 5 mm mesh. Zooplankton in each size class were transferred onto pre-weighed 0.15 mm nitex mesh filters and rinsed with deionized water. Samples were then dried for 24 hours at 60 degrees C and weighed.

DatasetSeries 4: Aggregation of Thalassiosira weissflogii as a function of pCO2, temperature and bacteria(Biological and Chemical Oceanography Data Management Office (BCO-DMO). Contact: bco-dmo-data@whoi.edu, 2013-09-05) Passow, Uta ; Seebah, ShalinIncreasing Transparent Exopolymer Particle (TEP) formation during diatom blooms as a result of elevated temperature and pCO2 have been suggested to result in enhanced aggregation and carbon flux, therewith potentially increasing the sequestration of carbon by the ocean. We present experimental results on TEP and aggregate formation by Thalassiosira weissflogii (diatom) in the presence or absence of bacteria under two temperature and three pCO2 scenarios. During the aggregation phase of the experiment TEP formation was elevated at the higher temperature (20ºC vs. 15ºC), as predicted. However, in contrast to expectations based on the established relationship between TEP and aggregation, aggregation rates and sinking velocity of aggregates were depressed in warmer treatments, especially under ocean acidification conditions. If our experimental findings can be extrapolated to natural conditions, they would imply a reduction in carbon flux and potentially reduced carbon sequestration after diatoms blooms in the future ocean.

DatasetThe role of regenerated nitrogen for rocky shore productivity, Cape Flattery, Washington, 2010 & 2011(Biological and Chemical Oceanography Data Management Office (BCO-DMO). Contact: bco-dmo-data@whoi.edu, 2014-02-04) Pather, Santhiska ; Pfister, Catherine A. ; Altabet, Mark A. ; Post, DavidStable isotope tracers were added to exposed tidepools utilizing them as temporary mesocosms to quantify N transformation rates (Pather et al.,L&O). Large tracer signals were observed over the typical 4-5 hr experimental period in both the dilution of the isotope label in its added form (NH4+ or NO3-) and the appearance of the label in products (e.g. NO2-) The primary advantage was that all members of community participated in the experiment allowing us to recognize the complexity of nitrogen cycling in this system.

The database holds 476,000 quantitative, categorical, presence-absence and presence only records of gelatinous zooplankton spanning the past four centuries (1790-2011) assembled from a variety of published and unpublished sources. Gelatinous zooplankton data are reported to species level, where identified, but taxonomic information on phylum, family and order are reported for all records. Other auxiliary metadata, such as physical, environmental and biometric information relating to the gelatinous zooplankton metadata, are included with each respective entry. JeDI has been developed and designed as an open access research tool for the scientific community to quantitatively define the global baseline of gelatinous zooplankton populations and to describe long-term and large-scale trends in gelatinous zooplankton populations and blooms. It has also been constructed as a future repository of datasets, thus allowing retrospective analyses of the baseline and trends in global gelatinous zooplankton populations to be conducted in the future.

DatasetEastern Tropical South Pacific Nitrogen fixation(Biological and Chemical Oceanography Data Management Office (BCO-DMO). Contact: bco-dmo-data@whoi.edu, 2015-04-16) Knapp, Angela ; Casciotti, Karen L. ; Berelson, William M. ; Prokopenko, Maria ; Capone, DouglasAn extensive region of the Eastern Tropical South Pacific (ETSP) Ocean has surface waters that are nitrate-poor yet phosphate-rich. It has been proposed that this distribution of surface nutrients provides a geochemical niche favorable for N2 fixation, the primary source of nitrogen to the ocean. Here, we present results from two cruises to the ETSP where rates of N2 fixation and its contribution to export production were determined with a suite of geochemical and biological measurements. N2 fixation was only detectable using nitrogen isotopic mass balances at two of six stations, and rates ranged from 0 to 23 µmol N m-2 d-1 based on sediment trap fluxes. Whereas the fractional importance of N2 fixation did not change, the N2-fixation rates at these two stations were several-fold higher when scaled to other productivity metrics. Regardless of the choice of productivity metric these N2-fixation rates are low compared with other oligotrophic locations, and the nitrogen isotope budgets indicate that N2 fixation supports no more than 20% of export production regionally. Although euphotic zone-integrated short-term N2-fixation rates were higher, up to 100 µmol N m-2 d-1, and detected N2 fixation at all six stations, studies of nitrogenase gene abundance and expression from the same cruises align with the geochemical data and together indicate that N2 fixation is a minor source of new nitrogen to surface waters of the ETSP. This finding is consistent with the hypothesis that, despite a relative abundance of phosphate, iron may limit N2 fixation in the ETSP.

DatasetSeries 5: pCO2 as one of multiple stressors for Thalassiosira weissflogii(Biological and Chemical Oceanography Data Management Office (BCO-DMO). Contact: bco-dmo-data@whoi.edu, 2015-12-14) Passow, Uta ; Laws, Edward A.The increase in partial pressure of CO2 (pCO2) is causing ocean acidification, which impacts the growth rates and elemental composition of phytoplankton. Here, shifts in growth rates and cell quotas of Thalassiosira weissflogii grown under a variety of different temperatures, irradiances, and pCO2 conditions are discussed.
