Atmospheric deposition of mercury and major ions to the Pensacola (Florida) watershed: spatial, seasonal, and inter-annual variability
mercury major ions the Pensacola (Florida) watershed inter-annual variability
2010/8/13
Atmospheric deposition was measured at three sites in the Pensacola Bay watershed, Florida, between November 2004 and December 2007. Mercury deposition in the Pensacola Bay watershed was similar to th...
Cyclic modes of the intra-annual variability of precipitation in Greece
Cyclic modes intra-annual variability of precipitation
2010/9/10
The application of harmonic analysis to the annual variability of precipitation is the object of this study, so that the modes, which compose the annual variability, be elicited. For this purpose, mon...
Annual Variability in Summer Evapotranspiration and Water Balance at a Subarctic Forest Site
Annual Variability Summer Evapotranspiration Water Balance
2009/10/26
Evapotranspiration (ET) and precipitation were measured during five summers
(1989-1993 inclusive) at a subarctic forest site near Churchill, Manitoba, Canada.
Mean daily ET varied from 2.14-3.18 mm ...
Trends and inter-annual variability of methane emissions derived from 1979-1993 global CTM simulations
Trends and inter-annual variability methane emissions global CTM simulations
2009/3/10
The trend and interannual variability of methane sources are derived from multi-annual simulations of tropospheric photochemistry using a 3-D global chemistry-transport model. Our semi-inverse analysi...
Calibration of the INCA model in a Mediterranean forested catchment: the effect of hydrological inter-annual variability in an intermittent stream
environmental modelling intermittent stream
2009/3/6
Mediterranean regions are characterised by a stream hydrology with a marked seasonal pattern and high inter-annual variability. Accordingly, soil N processes and leaching of solutes in Mediterranean r...
Drivers of inter-annual variability in Net Ecosystem Exchange in a semi-arid savanna ecosystem,South Africa
inter-annual variability Net Ecosystem Exchange semi-arid savanna ecosystem
2010/1/19
Inter-annual variability in primary production and ecosystem respiration was explored using eddy-covariance data at a semi-arid savanna site in the Kruger Park, South Africa. New methods of extrapolat...
Tropopause referenced ozone climatology and inter-annual variability (1994–2003) from the MOZAIC programme
Tropopause referenced ozone climatology inter-annual variability MOZAIC programme
2009/1/5
The MOZAIC programme collects ozone and water vapour data using automatic equipment installed on board five long-range Airbus A340 aircraft flying regularly all over the world since August 1994. Those...
Annual Variability of the Subtropical Recirculations in the North Atlantic and North Pacific：A Topex/Poseidon Study
Subtropical Recirculations North Atlantic North Pacific Topex/Poseidon Study
2008/12/11
Using sea surface height data collected by Geosat and Topex/Poseidon, the seasonal (annual) gyre circulations in the regions of the Gulf Stream and the Kuroshio Extension were studied. The seasonal gy...
A Numerical Investigation of the Annual Variability in the Gulf of California
Numerical Investigation Gulf of California Annual Variability
2008/11/18
The observations of sea level at the annual frequency in the Gulf of California are reproduced both in amplitude and phase with a horizontal two-dimensional linear two-layer model. The main forcing ag...
Inverse Modeling of Intra-annual Variability in the Subtropical North Pacific
Inverse Modeling of Intra-annual Variability in the Subtropical North Pacific
2008/6/20
Climatological data on the oceanic and atmospheric variability are inverted to study seasonal variation of the Kuroshio Extension (KE) and the recirculation gyre to the south. The processed datasets i...
Inter-annual variability of the carbon dioxide oceanic sink south of Tasmania
Inter-annual variability carbon dioxide oceanic sink south of Tasmania
2010/1/15
We compiled a large data-set from 22 cruises spanning from 1991 to 2003, of the partial pressure of CO2 (pCO2) in surface waters over the continental shelf (CS) and adjacent open ocean (43° to 46° S; ...
Inter-annual variability of the Pelagic-Benthic coupling in the upwelling system off central Chile
the Pelagic-Benthic coupling the upwelling system central Chile
2010/1/25
The coastal region of central Chile (36° S) is one of the most productive coastal systems, characterized by a marked seasonality in the upwelling regime, that brings subsurface waters rich in nutrient...
Seasonal and annual variability in the spatial patterns of plankton biomass in Chesapeake Bay
Seasonal and annual variability spatial patterns plankton biomass Chesapeake Bay
2014/5/9
We conducted high-resolution, underway sampling in April, July, and October for 6 yr (1995-2000) in the large estuary, Chesapeake Bay. This period included climatological extremes in freshwater inputs...
