Late Quaternary variability of sedimentary nitrogen isotopes in the eastern South Pacific Ocean
(American Geophysical Union, 2007-05-01)
We present high-resolution bulk sedimentary δ 15N data from the southern edge of the present-day oxygen minimum zone of the eastern South Pacific. The record is interpreted as representing changes in water column nitrogen ...
Higher-order acoustic diffraction by edges of finite thickness
(Acoustical Society of America, 2007-12)
A cw solution of acoustic diffraction by a three-sided semi-infinite barrier or a double edge, where the width of the midplanar segment is finite and cannot be ignored, involving all orders of diffraction is presented. The ...
Stochastic flood and precipitation regimes and the population dynamics of a threatened floodplain plant
(Ecological Society of America, 2005-06)
Boltonia decurrens is an endangered plant restricted to the Illinois River Valley. Its complex life cycle has evolved in response to the dynamics of the historic flood regime, which has changed dramatically in the last ...
Noble gas constraints on air-sea gas exchange and bubble fluxes
(American Geophysical Union, 2009-11-19)
Air-sea gas exchange is an important part of the biogeochemical cycles of many climatically and biologically relevant gases including CO2, O2, dimethyl sulfide and CH4. Here we use a three year observational time series ...
Wave evolution across the Louisiana shelf
Observations and third-generation wave model hindcasts of ocean surface gravity waves propagating across the Louisiana shelf show that the effects of the mud environment on wave evolution are complex and episodic. Whereas ...
Cloning a new cytochrome P450 isoform (CYP356A1) from oyster Crassostrea gigas
We have cloned the full-length cDNA of the first member of a new cytochrome P450 (CYP) family from the Pacific oyster Crassostrea gigas. This new CYP gene was obtained based on an initial 331 bp fragment previously ...
Sound Cut, Record Number 66038Ahi1_01
(Woods Hole Oceanographic Institution, 2007-08-14)
Recording of unknown number of Bearded seals.
Circulation in upper layers of southern North Atlantic deduced with use of isentropic analysis
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1938-08)
Except for the presence in most localities of a shallow homogeneous surface layer and of a relatively homogeneous and deeper bottom layer, the oceans of the temperate and tropical regions are stratified and vertically ...
Coupled nature-human (CNH) systems : generic aspects of human interactions with blooms of Florida Red Tide (Karenia brevis) and implications for policy responses
Coupled nature-human (CNH) systems are now the focus of a growing number of interdisciplinary re-search programs worldwide (Liu et al. 2007a). As implied by the term “coupled,” these systems involve interactions between ...
Production and destruction of eddy kinetic energy in forced submesoscale eddy-resolving simulations
We study the production and dissipation of the eddy kinetic energy (EKE) in a submesoscale eddy field forced with downfront winds using the Process Study Ocean Model (PSOM) with a horizontal grid resolution of 0.5 km. We ...
