22 p, 2.5 MB Links between fish abundance and ocean biogeochemistry as recorded in marine sediments / Kavanagh, Lucas (McGill University, Montréal. Department of Earth and Planetary Sciences) ; Galbraith, Eric D. (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals)
Fish populations are linked to ocean biogeochemistry by their reliance on primary production for food, and dissolved oxygen to breathe. It is also possible that marine fish modify biogeochemical dynamics, as do freshwater fish, through top-down trophic cascades, but there has been relatively little consideration of this possibility.

13 p, 237.7 KB Status of alkenone paleothermometer calibration : report from Working Group 3 / Prahl, F. (Oregon State University. College of Oceanic and Atmospheric Sciences) ; Herbert, T. D. (Brown University. Department of Geological Sciences) ; Brassell, S. C. (Indiana University. Biogeochemical Laboratories) ; Ohkouchi, N. (Woods Hole Oceanographic Institution.

(Woods Hole Oceanographic Institution. Fye Laboratory) ; Sikes, E. (University of Auckland. SEMS/Geology)
The alkenone unsaturation index, U37K′, has now proven its worth as a tool for paleothermometry. U37K′ measured in most modern sediments throughout the World Ocean can be translated using established calibrations into realistic, seemingly reliable estimates of mean annual temperature at the sea surface (SST).

BACKGROUND: The microbial fuel cell (MFC) technology transforms the chemical energy present in substrates into electricity. Starting-up these systems, i. e. enriching the anodic community in exoelectrogenic bacteria, is a lengthy process or requires expensive equipment. [...]

17 p, 2.6 MB Holocene palaeoecological changes recorded in mollusc-bearing cave sediments, the Cave above the Słupska Gate (southern Poland) / Szymanek, M. (University of Warsaw. Faculty of Geology) ; Krajcarz, M. (Polish Academy of Sciences. Institute of Geological Sicences) ; Krajcarz, M. T. (Polish Academy of Sciences. Institute of Geological Sicences) ; Alexandrowicz, W. P. (AGH University of Science and Technology. Faculty of Geology, Geophysics and Environment Protection)
The Cave above the Słupska Gate (southern Poland) contains about 2m depth of mollusc-bearing deposits. Radiocarbon and archaeological dating indicate that these deposits accumulated during the Holocene (Preboreal to Subatlantic), although the earliest layers may date from the end of the Pleistocene.

Instituto de Oceonografía y Cambio Global) ; Sánchez-García, M.J. (Universidad de Las Palmas de Gran Canaria. Instituto de Oceonografía y Cambio Global)
Recovery rates were obtained by radio frequency identification (RFID) technology in pebbles and cobbles at SanFelipe beach, Gran Canaria. The aim of this work was to define which factors affected the recovery of taggedgravels. [...]

In the southern Sierra Sonobari, NW Mexico, U-Pb and 40Ar/39Ar geochronology studies allowed to define the provenance and maximum depositional age of the Francisco Gneiss basement of the Sonobari terrane, and to establish the age of some magmatic events in that area. [...]

To determine the spatial heterogeneity of the physical and chemical characteristics of superficial sediments from the Ribarroja Reservoir, we have analysed particle size distribution and concentrations of major (Al, Fe, Si, K, Ca, Mg, Ti, Mn and P) and minor (Mo, Nb, Zr, Y, Sr, Rb, Th, Pb, Sn, Ce, Ga, Zn, W, Cu, Co, Ni and V) elements at sixteen sites distributed along the reservoir.
