title: KOSMOS Finland 2012 mesocosm study: Size-fractionated bacterial protein production (BPP) of free-living and particle associated bacteria and abundance of particle associated heterotrophic prokaryotes.

description: The oceans absorb about a quarter of the annually produced anthropogenic atmospheric carbon dioxide (CO2), resulting in a decrease in surface water pH, a process termed ocean acidification (OA). Surprisingly little is known about how OA affects the physiology of heterotrophic bacteria or the coupling of heterotrophic bacteria to phytoplankton when nutrients are limited. Previous experiments were, for the most part, undertaken during productive phases or following nutrient additions designed to stimulate algal blooms. Therefore, we performed an in situ large-volume mesocosm (ca. 55 m**3) experiment in the Baltic Sea by simulating different fugacities of CO2 (fCO2) extending from present to future conditions. The study was conducted in July?August after the nominal spring bloom, in order to maintain low-nutrient conditions throughout the experiment. This resulted in phytoplankton communities dominated by small-sized functional groups (picophytoplankton). There was no consistent fCO2-induced effect on bacterial protein production (BPP), cell-specific BPP (csBPP) or biovolumes (BVs) of either free-living (FL) or particle-associated (PA) heterotrophic bacteria, when considered as individual components (univariate analyses). Permutational Multivariate Analysis of Variance (PERMANOVA) revealed a significant effect of the fCO2 treatment on entire assemblages of dissolved and particulate nutrients, metabolic parameters and the bacteria?phytoplankton community. However, distance-based linear modelling only identified fCO2 as a factor explaining the variability observed amongst the microbial community composition, but not for explaining variability within the metabolic parameters. This suggests that fCO2 impacts on microbial metabolic parameters occurred indirectly through varying physicochemical parameters and microbial species composition. Cluster analyses examining the co-occurrence of different functional groups of bacteria and phytoplankton further revealed a separation of the four fCO2-treated mesocosms from both control mesocosms, indicating that complex trophic interactions might be altered in a future acidified ocean. Possible consequences for nutrient cycling and carbon export are still largely unknown, in particular in a nutrient-limited ocean.

title: Data collection of Calanus finmarchicus reproduction life history traits in the North Atlantic Ocean

description: Observations of egg production rates (EPR) for female Calanus finmarchicus were compared from different regions of the North Atlantic. The regions were diverse in size and sampling frequency, ranging from a fixed time series station in the Lower St Lawrence Estuary, off Rimouski, where nearly 200 experiments were carried out between May and December from 1994 to 2006, to a large-scale survey in the Northern Norwegian Sea, where about 50 experiments were carried out between April and June from 2002 to 2004. For this analysis the stations were grouped mostly along geographic lines, with only limited attention being paid to oceanographic features. There is some overlap between regions, however, where stations were sometimes kept together when they were sampled on the same cruise. As well some stations other than off Rimouski were occupied more than once during different years and/or in different seasons.

title: Noble gases measured on water bottle samples during METEOR cruise M91

description: Coastal upwelling regions as the research area of the Metor cruise M91 off Peru belong to the most productive regions of the world ocean. Oceanic upwelling velocities, however, are too small to be measured directly. We will thus exploite the deviations of the helium-3/helium-4 ratio from the atmospheric solubility equilibrium in the case of upwelling to infer the vertical velocities. This method has already been applied in the equatorial eastern Atlantic and the coastal region off Mauritania. The resulting vertical velocities will be compared with Ekman theory. In conjunction with other measurements perfomed during M91, the upwelling velocities can be used to estimate advective transport of heat, nutrients and climate relevant trace gases into the mixed layer. Measurement and scientific evaluation of the helium data will be done in the framework of the German project SOPRAN (phase III). 335 helium samples in copper tubes have been taken from the Niskin bottles. Sampling focuses on the mixed layer and the upper 200 m of the water column. The aim of the sampling strategy is to minimize the error of the mixed layer concentration of helium-3 and to get mean values of the helium-3 concentration and gradient below the surface in order to estimate the advective and diffusive input of helium-3 into the mixed layer. In a first step, the gas has to be extracted from the water stored in the copper tubes, and this gas will then be transferred to a high resolution mass spectrometer. In addition to the helium isotopes helium-3 and helium-4, also the neon concentration of the water samples will be analysed.See "Further details:" for information on measurement technique.

title: A European-wide 222Radon and 222Radon progeny comparison study [Dataset]

description: Although atmospheric 222Radon (222Rn) activity concentration measurements are currently performed world-wide, they are being made by many different laboratories and with fundamentally different measurement principles, so compatibility issues can limit their utility for regional-to-global applications. Consequently, we conducted a European‐wide 222Rn/222Rn progeny comparison study in order to evaluate the different measurement systems in use, determine potential systematic biases between them, and estimate correction factors that could be applied to harmonize data for their use as a tracer in atmospheric applications. Two compact portable Heidelberg Radon Monitors (HRM) were moved around to run for at least one month at each of the nine European measurement stations included in this comparison. Linear regressions between parallel data sets were calculated, yielding correction factors rela
tive to the HRM ranging from 0.68 to 1.45. A calibration bias between ANSTO (Australian Nuclear Science and Technology Organisation) two‐filter radon monitors and the HRM of ANSTO/HRM = 1.11±0.05 was found. Moreover, for the continental stations using one‐filter systems that derive atmospheric 222Rn activity concentrations from measured atmospheric progeny activity concentrations, preliminary 214Po/222Rn disequilibrium values were also estimated. Mean station-specific disequilibrium values between 0.8 at mountain sites (e.g. Schauinsland) and 0.9 at non‐mountain sites for sampling heights around 20 to 30 m above ground level were determined. The respective corrections for calibration biases and disequilibrium derived in this study need to be applied to obtain a compatible European atmospheric 222Rn data set for use in quantitative applications, such as regional model intercomparison and validation, or trace gas flux estimates with the Radon‐Tracer‐Method.

title: The Lena River Delta - inventory of lakes and geomorphological terraces

description: This data set provides a detailed inventory of lakes in the Lena Delta, northern Siberia, with respect to the lakes' association with one of the three geomorphological main terraces of the Lena Delta. The inventory is based on Landsat-7 ETM+ image data and spatial analysis in a Geographical Information System (GIS). Several morphometric lake attributes were determined from the resulting dataset and statistically analyzed. Significant differences in the morphometric lake characteristics allowed the distinction of a mean lake type for each main terrace. The lake types reflect the special lithological and cryolithological conditions and geomorphological processes prevailing on each terrace. In Morgenstern et al. (2008), special focus was laid on the investigation of lake orientation and the discussion of possible mechanisms for the evolution of the second terrace's oriented lakes.
description: The lake data sets were automatically extracted from a Landsat 7 ETM+ mosaic of the Lena delta (Schneider et al. 2009) by using grey-level thresholding of band 5 (Morgenstern et al., 2008). On the second terrace in the western Lena Delta, several coalesced lakes occur, which is obvious from deep basins divided by flat underwater ridges, some of them cut by deeper channels beneath the present lake water level. As our analyses were aimed on lake genesis, we manually divided the coalesced lakes (n=51) along the middle line of the ridges into their single basins and treated each basin as an individual lake (n=120 of which n=17 &lt; 20 ha were excluded from further analysis).The second geomorphological terrace of the Lena River Delta was modified from Röhr (2001) on the basis of a Landsat 7 ETM+ mosaic (Schneider et al., 2009) with expert advice from Mikhail N. Grigoriev (Morgenstern et al., 2008). The third geomorphological terrace of the Lena River Delta was manually digitized by G. Grosse, AWI Potsdam, based on Landsat 7 ETM+ data of the Lena delta, then modified by Anne Morgenstern with field and expert advice from Mikhail N. Grigoriev (Morgenstern et al., 2008). See further details for an overview of region.
