Physicochemical and biological controls on primary and net community production across northeast Pacific seascapes
northeast Pacific seascapes Physicochemical biological controls
2014/11/28
The subarctic–subtropical transition zone in the North Pacific represents the second largest sink of
atmospheric carbon dioxide in the world ocean, yet the relative importance of physical and biologi...
Nitrogen enrichment increases net silica accumulation in a temperate salt marsh
Nitrogen enrichment increases net silica accumulation a temperate salt marsh
2014/4/2
Two New England salt marshes exposed to different N availability were assessed seasonally for 1 yr, creating the first complete salt marsh Si budgets. Triplicate seasonal measurements were collected f...
Comparing Process-Based Net Primary Productivity Models in a Mediterranean Watershed
NPP Modelling Remote Sensing Percent Tree Cover Model Comparison CASA LPJ-GUESS
2014/4/22
The aim of this study was to compare the estimation capability of two different process-based NPP models (CASA and LPJGUESS) in a Mediterranean watershed. Remotely sensed data and climate time series ...
Mats of the nonnative macroalga, Gracilaria vermiculophylla, alter net denitrification rates and nutrient fluxes on intertidal mudflats
nonnative macroalga Gracilaria vermiculophylla
2014/4/2
We hypothesized that mats of a nonnative macroalga, Gracilaria vermiculophylla, which is often found
incorporated several centimeters into intertidal mudflat sediments, would increase net denitrifica...
The role of net community production in air–sea carbon fluxes at the North Pacific subarctic–subtropical boundary region
air–sea carbon fluxes net community production
2014/4/17
The North Pacific subarctic–subtropical boundary region is an important sink for atmospheric CO2
, with high
annual influx relative to surrounding waters and large seasonal variability. The location...
Drivers of metabolism and net heterotrophy in contrasting lakes
Drivers of metabolism net heterotrophy
2014/4/16
We investigated the influence of light, nutrients, and organic matter on gross primary production (GPP),
ecosystem respiration (R), and net ecosystem production (NEP 5 GPP 2 R) in a dystrophic forest...
The Net Transport of the Antarctic Circumpolar Current through Drake Passage
Net Transport Drake Passage Antarctic Circumpolar Current
2009/2/8
Estimates of the net transport through Drake Passage are made for three periods during which the year-long DRAKE 79 current meter array spanning the Passage was in operation. Relative geostrophic shea...
Interannual Variation in Net Heating at the Surface of the Tropical Pacific Ocean
Tropical Pacific Ocean Net Heating tropical Pacific Ocean
2009/2/5
Interannual variations of net surface heating of the tropical Pacific Ocean are analyzed for the period 1957–76. Special emphasis is given to exploring the relationship between these variations and th...
Applying a semantic information Petri Net modeling method to AUV systems design
autonomous underwater vehicle(AUV) colored Petri Net modeling language(CPNML) substitution transition reachable tree
2011/9/14
This paper informally introduces colored object-oriented Petri Nets(COOPN) with the application of the AUV system.According to the characteristic of the AUV system’s running environment,the object-ori...
Variational Data Assimilation for Determining the Seasonal Net Surface Heat Flux Using a Tropical Pacific Ocean Model
sea surface temperature Tropical Pacific Ocean Model surface heat flux
2008/12/12
The authors present a study for determining the seasonal net surface heat flux over the tropical Pacific Ocean using an adjoint technique. A simple tropical ocean model with thermodynamics is chosen a...
On the Net Cyclonic Circulation in Large Stratified Lakes
Net Cyclonic Circulation Large Stratified Lakes azimuthal flow
2008/10/31
Schwab et al. have investigated a possible cause of long-term cyclonic circulation often observed in stratified lakes. They conclude that the adiabatic boundary condition applied to the bottom boundar...
The Seasonal Heat Budget of the North Pacific: Net Heat Flux and Heat Storage Rates (1950–1990)
Seasonal Heat Budget North Pacific Net Heat Flux Heat Storage Rates
2008/10/31
A new estimate of the heat budget for the North Pacific Ocean is presented in this paper. The seasonal net heat flux and heat storage rates were calculated for the North Pacific Ocean from 1950 to 199...
Net community production in the deep euphotic zone of the subtropical North Pacific gyre from glider surveys
Net community production deep euphotic zone subtropical North Pacific gyre glider surveys
2014/5/16
Seagliders, deployed through most of 2005 in the subtropical North Pacific gyre, made measurements of temperature, salinity, and dissolved oxygen to quantify net community production (NCP) at Station ...
The Net Advective Effect of a Vertically Sheared Current on a Coherent Vortex
Net Advective Effect Vertically Sheared Current Coherent Vortex
2008/8/12
The nonlinear interaction of a localized vortex with a vertically sheared mean flow has been studied using numerical and asymptotic methods in a multilayer quasigeostrophic model on the beta plane.
