Barium and molybdenum records in bivalve shells: Geochemical proxies for phytoplankton dynamics in coastal environments?
Barium molybdenum records
2014/4/18
Barium : calcium and molybdenum : calcium ratios were investigated in shells of the tropical scallop
Comptopallium radula. Three juvenile specimens were harvested alive in the southwest lagoon of New...
Staying alive: The post-consumption fate of parasite spores and its implications for disease dynamics
Staying alive parasite spores disease dynamics
2014/4/18
Studies on the effects of selective predation by fish on disease dynamics in Daphnia generally assume that
consumption by fish means the death of the parasite. I use a combination of feeding trials a...
Biological consumption of dimethylsulfide (DMS) and its importance in DMS dynamics in the Ross Sea, Antarctica
dimethylsulfide DMS dynamics Ross Sea
2014/4/18
We studied the biological consumption of dimethylsulfide (DMS) and its role in controlling DMS
concentrations in the Ross Sea, Antarctica, during the spring (Nov) and summer (Jan) of 2005. Surface DM...
Groundwater recharge and discharge dynamics in an arid-zone ephemeral lake system, Australia
Groundwater recharge discharge dynamics
2014/4/17
The Coongie Lakes are a series of ephemeral freshwater lakes on the lower reaches of Cooper Creek, a large
intermittent river of the arid Lake Eyre Basin, Australia. Hydrogeological, chemical, and is...
Controls on the seasonal and interannual dynamics of organic matter stable carbon isotopes in mesotrophic Lake Holzmaar, Germany
interannual dynamics mesotrophic Lake Holzmaar Germany
2014/4/17
We investigated the particulate organic matter (POM) flux and its stable carbon isotope composition in
response to changes in phytoplankton primary production and abiotic environmental affects in mes...
Temporal dynamics of seston: A recurring nighttime peak and seasonal shifts in composition in a stream ecosystem
A recurring nighttime peak seasonal shifts
2014/4/17
We measured the baseflow concentration and composition of seston and suspended particulate organic carbon
(POC) over a 1-yr period in White Clay Creek, a third-order stream in the southeastern Pennsy...
A Numerical Investigation of Arctic Ocean Dynamics
Numerical Investigation Arctic Ocean Dynamics
2009/4/2
A barotropic numerical model of the Arctic Ocean is formulated to include irregular basin shape, variable bathymetry, lateral friction, bottom drag, and nonlinear advection terms. Source-sink distribu...
An integral model of the steady-state dynamics of a shallow, small-scale oceanic front is developed. Such fronts have been observed at the boundaries of river plumes discharging into coastal sea water...
Two time-dependent “vertical cross section models” are analyzed and applied to wind-driven currents in Lake Ontario. The models are: 1) a linear frictionless, two-level model, and 2) a numerical model...
The Structure and Dynamics of the Ocean Surface Mixed Layer
Structure Dynamics Ocean Surface Mixed Layer
2009/3/24
The present paper describes a one-dimensional unsteady model of the ocean surface mixed layer. The model somewhat resembles the approach of Munk and Anderson in that the differential equations for mea...
A Simple Model of Coastal Upwelling Dynamics
Coastal Upwelling Dynamics surface wind stress
2009/3/9
As a step in understanding the complicated dynamics of coastal upwelling areas, a simple theoretical model is examined. The motion is driven by surface wind stress acting on homogeneous water of const...
Maps from the Mid-Ocean Dynamics Experiment：Part II. Potential vorticity and its Conservation
Mid-Ocean Dynamics Experiment Conservation Potential vorticity
2009/3/7
Observations of float trajectories and vertical density profiles from the Mid-Ocean Dynamics Experiment are analyzed in terms of a likely equation of motion for mesoscale eddies involving the conserva...
Maps from the Mid-Ocean Dynamics Experiment：Part I. Geostrophic Streamfunction
Mid-Ocean Dynamics Experiment Geostrophic Streamfunction
2009/3/7
From measurements made during the 1973 Mid-Ocean Dynamics Experiment in the western North Atlantic, horizontal maps of the total dynamic pressure (or, in the geostrophic approximation, streamfunction)...
This paper describes a theoretical model of the ocean surface mixed layer. A nonstationary one-dimensional system of equations for an Ekman ocean layer and for heat conduction is closed with a system ...
Satellite Observations of Mesoscale Eddy Dynamics in the Eastern Tropical Pacific Ocean
Mesoscale Eddy Dynamics Eastern Tropical Pacific Ocean
2009/3/7
Active mesoscale (300 km diameter) eddy formation off the Pacific coast of Central America was observed during February 1976 by a thermal infrared sensor aboard the NOAA 4 satellite. These anticycloni...
