Death by dissolution : sediment saturation state as a mortality factor for juvenile bivalves

Creator:: Green, Mark A., Waldbusser, George G., Reilly, Shannon L., and Emerson, Karla
Abstract:: We show that death by dissolution is an important size-dependent mortality Utilizing a new experimental design, we were able to replicate saturation states frequently encountered by Mercenaria mercenaria in coastal deposits mercenaria were reared in sediments at Ωaragonite = 0.4 and 0.6, significant occurred (14.0% and 14.4% d⁻¹, respectively), relative...

Methane cycling in the sediments of Lake Washington

Creator:: Kuivilal, K. M., Murray, J. W., Devol, A. H., Lidstrom, M. E., and Reimers, Clare E.
Abstract:: Aerobic oxidation is important in the cycling of methane in the sediments of Lake Washington. About half of the methane flux from depth is oxidized to CO, in the upper 0.7 cm of the sediments and the remainder escapes into the water column. In terms of the total carbon budget...

Stratification and mixing regimes in biological thin layers over the Mid-Atlantic Bight

Creator:: Shroyer, E. L., Benoit-Bird, Kelly J., Nash, J. D., and Moum, J. N.
Abstract:: We use density and microstructure data to characterize the properties and physical setting of optical thin layers observed over the New Jersey shelf in the summer of 2006. Layers were differentiated into two types by their vertical position in the water column, fluorescence intensity, and possibly community composition or cell...

Seasonal variation in temperature, salinity, and density over the continental shelf off Oregon

Creator:: Huyer, Adriana, 1945-
Abstract:: Seasonal variations in the hydrography of the waters over the continental shelf off Oregon were observed in a set of hydrographic data collected along 44º39′N at intervals of a few weeks to a few months from 1961 through 1970. The temperature is determined only partly by the local heating and...

Methylammonium uptake by Chesapeake Bay phytoplankton: Evaluation of the use of the ammonium analogue for field uptake measurements

Creator:: Wheeler, Patricia A. and McCarthy, James J.
Abstract:: The uptake of methylammonium (MA) by Chesapeake Bay phytoplankton was measured in short term experiments by using the 14C radioisotope. This uptake was inversely related to ambient NH4+ concentrations, and the specificity for uptake of both substrates was demonstrated by competitive inhibition. At stations with low ambient NH4+, MA uptake...

Uptake of glycine by natural phytoplankton communities

Creator:: Wheeler, Patricia A., North, B., Littler, M., and Stephens, G.
Abstract:: Uptake of [14C]glycine by various size fractions of natural plankton communities was measured to determine if phytoplankton can compete effectively with other members of the plankton community for the free amino acids in seawater. The simultaneous occurrence of glycine uptake, plant pigments, and photosynthetic activity in the same size fractions,...

Comment on Bachmann et al. (2013): A nonrepresentative sample cannot describe the extent of cultural eutrophication of natural lakes in the United States

Creator:: McDonald, Cory P., Lottig, Noah R., Stoddard, John L., Herlihy, Alan T., Lehmann, Sarah, Paulsen, Steven G., Peck, David V., Pollard, Amina I., and Stevenson, R. Jan
Abstract:: In their recent paper, Bachmann et al. (2013) evaluate the extent to which natural lakes in the contiguous United States have been affected by cultural eutrophication since Europe-an settlement, using paleolimnological data collected during the 2007 National Lakes Assessment (NLA; U.S. Environ-mental Protection Agency [USEPA] 2009). The NLA sites were...

An automatic and quantitative approach to the detection and tracking of acoustic scattering layers

Creator:: Cade, David E. and Benoit-Bird, Kelly J.
Abstract:: Acoustic scattering layers are ubiquitous, horizontally extensive aggregations of both vertebrate and invertebrate organisms that play key roles in oceanic ecosystems. However, currently there are no conventions or widely adaptable automatic methods for identifying these often dynamic, spatially complex features, so it is difficult to consistently and efficiently describe and...

Diversity trumps acidification : lack of evidence for carbon dioxide enhancement of Trichodesmium community nitrogen or carbon fixation at Station ALOHA

Creator:: Gradoville, Mary R., White, Angelicque E., Böttjer, Daniela, Church, Matthew J., and Letelier, Ricardo M.
Abstract:: We conducted 11 independent short-term carbon dioxide (CO₂) manipulation experiments using colonies of the filamentous cyanobacteria Trichodesmium isolated on three cruises in the North Pacific Subtropical Gyre (NPSG). Dinitrogen (N₂) and carbon (C) fixation rates of these colonies were compared over CO₂ conditions ranging from ~ 18 Pa (equivalent to...

Miniature thermistor chain for determining surficial sediment porewater advection

Creator:: Fram, Jonathan P., Pawlak, Geno R., Sansone, Francis J., Glazer, Brian T., and Hannides, Angelos K.
Abstract:: A miniature thermistor chain (mTc) was developed to measure the subdiurnal variability of temperature in the upper layers of subtidal coastal permeable (sandy) sediments and across the sediment-water interface (SWI). The mTc has 15 precision thermistors (0.002°C accuracy) attached by narrow tines to a stainless steel backbone that connects to...
