Black Sea Ecosystem Response to Climatic Teleconnections
Black Sea Ecosystem Climatic Teleconnections
2015/7/27
Marine ecosystems respond to climate changes at all trophic levels, from primary producers to herbivores to higher predators, in terms of growth, life history traits, and population dynamics (Stensth ...
Climatic forcing of zooplankton dynamics is stronger during low densities of planktivorous fish
Climatic forcing of zooplankton dynamics planktivorous fish
2014/4/18
We analyze interannual variation in zooplankton biomass in the southwestern Barents Sea in spring (May) and
summer (June–July) 1959–1993. Using a threshold modeling approach, we quantify spatial, cli...
Ecological, landscape, and climatic regulation of sediment geochemistry in North American sockeye salmon nursery lakes: Insights for paleoecological salmon investigations
sediment geochemistry Ecological landscape climatic
2014/4/17
We used multiple linear regressions across a Northeast Pacific region 56-lake set to examine the influence of
sockeye salmon spawner densities and limnological, climatic, and watershed characteristic...
On a Thermal Lag in the North Atlantic Ocean during a Climatic Change
Thermal Lag Climatic Change the North Atlantic Ocean
2009/3/7
An analysis was made of (i) the annual sea-surface temperature in the northern North Atlantic; (ii) the sea temperatures (0–200 m) along 33°00′E between 70°30′ and 72°30′N (Kola Section) representativ...
Climatic Teleconnections in the Western South Pacific with El-Niño Phenomenon
Climatic Teleconnections El-Niñ o Phenomenon Western South Pacific
2009/2/19
In the western South Pacific, one year after a typical El Niño event, anomalous hydroclimatic conditions replace the usual ones. The abnormal meteorological conditions are characterized by the ...
Short-Term Climatic Variability in the Thermal Structure of the Pacific Ocean during 1979–82
sea surface temperature Short-Term Climatic Variability Thermal Structure
2009/1/16
Short-term climatic variability in both sea surface temperature (SST) and vertically averaged temperature over the upper 400 m of ocean (Tav) is mapped over the Pacific from 20°S to 50°N each bimonth ...
Short-Term Climatic Variability in the Volume Budget of the Western Tropical North Pacific Ocean during 1979–82
eigenfunctions Short-Term Climatic Variability Western Tropical North Pacific Ocean
2009/1/7
Anomalous 14°C isotherm depth and anomalous geostrophic volume transport above the 14°C isotherm depth are calculated in the tropical Pacific for each bimonth of the four year period 1979 to 1982, bas...
Long-term changes in legacy trace organic contaminants and mercury in Lake Ontario salmon in relation to source controls, trophodynamics, and climatic variability
legacy trace organic contaminants mercury
2014/5/5
We used long-term (20+ yr) datasets to determine how the sum of 209 polychlorinated biphenyl congeners
([SPCB]), dodecachloropentacyclodecane ([mirex]), para-para dichlorodiphenyltrichloroethane ([ p...
Comprehensive trend analysis of nutrients and related variables in a large eutrophic estuary: A decadal study of anthropogenic and climatic influences
Comprehensive trend analysis related variables
2014/4/30
We used a decadal data set, with weekly to biweekly sampling in April–October and monthly sampling in November–
March, to characterize climatic (hurricane-level storms, a sustained 3-yr drought) and ...
Anthropogenic and climatic influences on the eutrophication of large estuarine ecosystems
Anthropogenic climatic infl uences
2014/4/30
We examined the effects of anthropogenic and climatic perturbations on nutrient–phytoplankton interactions and
eutrophication in the waters of the largest estuarine systems in the U.S.A., the Chesape...

climatic variability Lake Washington
2014/5/14
We conducted a statistical analysis of a long-term (1964–1998) record of intra- and interannual temperature
fluctuations in Lake Washington, Washington. Lake Washington has experienced a warmin...
Climatic forcing and primary productivity in a subalpine lake: Interannual variability as a natural experiment
Climatic forcing primary productivity a subalpine lake Interannual variability natural experiment
2014/5/14
We analyzed a 42-yr record of primary productivity in small, subalpine Castle Lake to determine how climatic variability might influence lake primary productivity. A Pacific Decadal Oscillation (PDO) ...
Climatic control of ultraviolet radiation effects on lakes
Climatic control ultraviolet radiation lakes
2014/5/21
Ultraviolet radiation (UVR) damages most biota, yet little evidence exists for its long-term effects on natural ecosystems. We used paleoecological techniques at three low-elevation lakes to show that...
