Less life:Limited phosphorus recycling suppressed early Earth’s biosphere
Less life Limited phosphorus recycling early Earth’s biosphere
2017/12/18
As Earth’s oxygen levels rose to near-modern levels over the last 800 million years, phosphorus levels also increased, according to modeling led by the UW’s Michael Kipp and others. Accordingly, Kipp ...
Ammonium uptake and dinitrogen fixation by the unicellular nanocyanobacterium Crocosphaera watsonii in nitrogen-limited continuous cultures
nanocyanobacterium Crocosphaera Ammonium uptake
2014/4/2
Ammonium uptake and nitrogen (N) fixation of the unicellular nanocyanobacterium Crocosphaera watsonii
isolated from the western subtropical North Pacific were determined in N-limited continuous cultu...
Increased intracellular concentrations of DMSP and DMSO in iron-limited oceanic phytoplankton Thalassiosira oceanica and Trichodesmium erythraeum
Increased intracellular DMSO Trichodesmium erythraeum
2014/4/2
We investigated the link between iron (Fe) limitation and intracellular dimethylsulfoniopropionate (DMSP)
concentration in two oceanic phytoplankton species, the diatom Thalassiosira oceanica and the...
Theoretical interpretation of fetch limited wind-drivensea observations
Theoretical interpretation fetch limited wind-drivensea observations
2009/11/11
We show that the results of major fetch limited field studies of wind-generated surface gravity waves on deep water can be explained in the framework of simple analytical model. The spectra measured i...
Use of Analytical Modeling and Limited Data for Prediction of Mesoscale Eddy Properties
Analytical Modeling Mesoscale Eddy Properties Limited Data
2009/2/11
The use of analytical modeling in the study of oceanic eddies is considered. Limited observational data, in combination with eddy models, are used to obtain analytical approximations to environmental ...
Development of a Three-Dimensional, Limited-Area (Island) Shelf Circulation Model
Three-Dimensional Limited-Area (Island) Shelf Circulation
2009/2/7
A three-dimensional, finite-difference model is developed to study limited-area (island) shelf circulation. The model uses a semi-implicit scheme in the cross-shore dimension and a mode-splitting tech...
On the Balance Between Growth and Dissipation in an Extreme Depth-Limited Wind-Sea in the Southern North Sea
Extreme Depth-Limited Wind-Sea Southern North Sea
2009/2/6
Bouwa has given a discussion of a severe storm in the southern North Sea, on 3 January 1976 near Texel, one of the Friesian islands. This storm was characterized by a remarkable steadiness of wind and...
Observations of the Directional Distribution of Ocean-Wave Energy in Fetch-Limited Conditions
Directional Distribution Ocean-Wave Energy Fetch-Limited Conditions
2009/1/22
Directional energy distributions of wind-generated waves were observed with a relatively high directional resolution in fairly homogeneous and stationary wind fields in fetch-limited conditions using ...
Assimilation of Altimeter Eddy Fields in a Limited-Area Quasi-Geostrophic Model
Altimeter Eddy Fields Limited-Area Quasi-Geostrophic Model
2009/1/9
Techniques for the synoptic analysis, vertical inference, dynamical adjustment, and forecast of altimetric and deeper in situ data are presented as a first step towards the design of continuous assimi...
A Limited-Area Model of the Gulf Stream：Design, Initial Experiments, and Model-Data Intercomparison
Limited-Area Model Gulf Stream Deep Western Boundary Current
2008/12/30
A primitive-equation, n-layer, eddy-resolving creation model has been applied to the Gulf Stream System from Cape Hatteras to cast of the Grand Banks (78°–45°W, 30°–48°N). Within the limitations of th...
An Examination of Fetch-Limited Wave Growth off the West Coast of New Zealand by a Comparison with the JONSWAP Results
Fetch-Limited Wave New Zealand ocean-wave field
2008/12/27
A long term wave recording program based on the west coast of New Zealand has allowed a number of fundamental properties of the ocean-wave field to be studied. This paper deals with wave-generation pr...
Bottom Friction for Wind Sea and Swell in Extreme Depth-Limited Situations
Bottom Friction Wind Sea Extreme Depth-Limited Situations
2008/12/23
A severe depth-limited storm and a case of extreme swell, which both occurred in the southern North Sea, are hindcasted with a regional version of the third-generation WAM model. This is done using di...
Observations of the Directional Spectrum of Fetch-Limited Waves
Directional Spectrum Fetch-Limited Waves
2008/10/31
Estimates of the wave directional spectrum of fetch-limited sea states are made from measurements made with a heave–pitch–roll buoy at the Maui location off the west coast of New Zealand. The fe...
Drag Coefficients with Fetch-Limited Wind Waves
Drag Coefficients Fetch-Limited Wind Waves
2008/6/20
Air–sea fluxes of momentum and heat were measured simultaneously with surface wind waves and near-surface currents in mid Chesapeake Bay during summer 1998 under low wind conditions. The data were col...
