High-Frequency in Situ Optical Measurements During a Storm Event: Assessing Relationships Between Dissolved Organic Matter, Sediment Concentrations, and Hydrologic Processes

Dissolved organic matter (DOM) dynamics during storm events has received considerable attention in forested watersheds, but the extent to which storms impart rapid changes in DOM concentration and composition in highly disturbed agricultural watersheds remains poorly understood. In this study, we used identical in situ optical sensors for DOM fluorescence (FDOM) with and without filtration to continuously evaluate surface water DOM dynamics in a 415 km(2) agricultural watershed over a 4 week period containing a short-duration rainfall event. Peak turbidity preceded peak discharge by 4 h and increased by over 2 orders of magnitude, while the peak filtered FDOM lagged behind peak turbidity by 15 h. FDOM values reported using the filtered in situ fluorometer increased nearly fourfold and were highly correlated with dissolved organic carbon (DOC) concentrations (r(2) = 0.97), providing a highly resolved proxy for DOC throughout the study period. Discrete optical properties including specific UV absorbance (SUVA(254)), spectral slope (S(290-350)), and fluorescence index (FI) were also strongly correlated with in situ FDOM and indicate a shift toward aromatic, high molecular weight DOM from terrestrially derived sources during the storm. The lag of the peak in FDOM behind peak discharge presumably reflects the draining of watershed soils from natural and agricultural landscapes. Field and experimental evidence showed that unfiltered FDOM measurements underestimated filtered FDOM concentrations by up to similar to 60% at particle concentrations typical of many riverine systems during hydrologic events. Together, laboratory and in situ data provide insights into the timing and magnitude of changes in DOM quantity and quality during storm events in an agricultural watershed, and indicate the need for sample filtration in systems with moderate to high suspended sediment loads.

Changes of dissolved organic matter compositions in artifical and natural seawater during Pseudovibrio growth experiment

To study the consumption of dissolved organic matter (DOM) by bacteria living in untra-oligotrophic artificial or natural seawater, we analyzed the composition of DOM before (timepoint t0, directly after inoculation) and after (timepoint t2, 3 weeks of incubation) growth of the bacteria using Fourier transform ion cyclotron mass spectrometry (ESI FT-ICR-MS). The oligotrophic natural seawater used originates from the South Pacific Gyre. Our data show that the bacteria were able to utilize a variety of different organic compounds. These compounds belong to different chemical compound groups and likely fuel the bacterial energy, carbon and nitrogen requirements under the ultra-oligotrophic conditions.

Dissolved organic matter in the Lena River Delta Region, Siberia, Russia

Connectivity between the terrestrial and marine environment in the Artic is changing as a result of climate change, influencing both freshwater budgets and the supply of carbon to the sea. This study characterizes the optical properties of dissolved organic matter (DOM) within the Lena Delta region and evaluates the behavior of DOM across the fresh water-marine gradient. Six fluorescent components (four humic-like; one marine humic-like; one protein-like) were identified by Parallel Factor Analysis (PARAFAC) with a clear dominance of allochthonous humic-like signals. Colored DOM (CDOM) and dissolved organic carbon (DOC) were highly correlated and had their distribution coupled with hydrographical conditions. Higher DOM concentration and degree of humification were associated with the low salinity waters of the Lena River. Values decreased towards the higher salinity Laptev Sea shelf waters. Results demonstrate different responses of DOM mixing in relation to the vertical structure of the water column, as reflecting the hydrographical dynamics in the region. Two mixing curves for DOM were apparent. In surface waters above the pycnocline there was a sharper decrease in DOM concentration in relation to salinity indicating removal. In the bottom water layer the DOM decrease within salinity was less. We propose there is a removal of DOM occurring primarily at the surface layer, which is likely driven by photodegradation and flocculation.

Molecular dissolved organic matter composition and environmental parameters from a laboratory incubation study

Dissolved organic matter (DOM) in the oceans constitutes a major carbon pool involved in global biogeochemical cycles. More than 96% of the marine DOM resists microbial degradation for thousands of years. The composition of this refractory DOM (RDOM) exhibits a molecular signature which is ubiquitously detected in the deep oceans. Surprisingly efficient microbial transformation of labile into RDOM was shown experimentally, implying that microorganisms produce far more RDOM than needed to sustain the global pool. By assessing the microbial formation and transformation of DOM in unprecedented molecular detail for 3 years, we show that most of the newly formed RDOM is molecularly different from deep sea RDOM. Only <0.4% of the net community production was channeled into RDOM molecularly undistinguishable from deep sea DOM. Our study provides novel experimentally derived molecular evidence and data for global models on the production, turnover and accumulation of marine DOM.

Determinación de índices de cosecha y calidad en kiwi en el sudeste bonaerense (Argentina)

Se realizó un seguimiento de la maduración de kiwis (Actinidia celiciosa (A. Chev.) Liang et Ferguson cv. Hayward) en una plantación comercial del sudeste de la provincia de Buenos Aires (Argentina), con la finalidad de definir índices de madurez y calidad y compararlos con los estándares vigentes en Nueva Zelanda y Chile. A intervalo semanal, desde las 13 semanas después de plena floración, se tomaron muestras de frutos para evaluar las siguientes variables: peso fresco, volumen, porcentaje de semillas negras, contenido de materia seca, acidez titulable y pH. De acuerdo con los mismos, el valor mínimo de sólidos solubles y el porcentaje de semillas negras exigido se alcanzaron durante la semana 21 después de plena floración y la firmeza de pulpa presentaba aún valores superiores al umbral recomendado. El momento óptimo de cosecha correspondió a plena temporada. Los resultados sugieren que la acidez titulable podría constituir otro índice de madurez. El porcentaje de materia seca no sería útil en fruta de plena temporada dado que los incrementos significativos se registran tempranamente. Sin embargo, puede ser útil como índice de calidad. Se plantea la posibilidad de utilizar la relación MS/AT como índice de calidad y de cosecha.

Una poética de la vocación en Marcel Proust

Se sostiene que es posible constituir una concepción de la vocación artística desde la propia ficción que contiene características extendibles a otros campos vocacionales. Se recurre a A la Recherche du Temps perdu de Marcel Proust, quien reflexiona críticamente sobre su propia obra y la condición del artista. Así destaca la importancia del azar, la infancia, la concreción en obra de una concepción adecuada del propio trabajo artístico, la memoria involuntaria, la vida vivida y su autocomprensión por el arte, la fuerza de convicción. La vocación es un llamado que supera la dicotomía don innato-producto social porque es resultado de una génesis de impresiones sensibles y rememoraciones involuntarias que, aunque fugaces, se fijan en la obra literaria. Se explica cómo la Recherche puede y no puede considerarse la historia de una vocación, pues la literatura no había desempeñado ningún papel en la vida del héroe novelístico pero sin embargo sí era la historia de una vocación pues la obra era la consecuencia de las experiencias vividas. No obstante, si bien nunca se le había dado a la vocación tanta importancia, debe triunfar en una batalla contra la muerte. Genette sintetiza la Recherche así: "Marcel deviene escritor".

Baseline surface radiation during the International Polar Year 2007-2009

Downwelling and upwelling shortwave and longwave radiation components from six active polar sites, taking part of the Baseline Surface Radiation Network (BSRN), were selected for the period of the last International Polar Year (March 2007 to March 2009), and included in the BSRN-IPY dataset, along with metadata and supplementary data for some of the stations. Two sites, located at Svalbard archipelago (Ny Ålesund) and Alaska (Barrow), represent Arctic sea-level conditions. Four Antarctic stations represent both sea-level (Dronning Maud Land and Cosmonaut Sea) and high-elevation conditions (South Pole and East Antarctic Plateau). The BSRN-IPY dataset content and quality are discussed.
