Understanding how climate varies in time is a central issue of climate research. Of particular interest are climate variations which occur within the human lifespan, say over 5- to 100-y time scales. ...
Warmer,lower-oxygen oceans will shift marine habitats
Warmer lower-oxygen oceans marine habitats
2015/6/18
Modern mountain climbers typically carry tanks of oxygen to help them reach the summit. It’s the combination of physical exertion and lack of oxygen at high altitudes that creates one of the biggest c...
A regime shift in Lake Superior ice cover, evaporation, and water temperature following the warm El Nin˜ o winter of 1997–1998
ice cover evaporation water temperature
2014/11/28
Significant trends in Lake Superior water temperature and ice cover have been observed in recent decades, and
these trends have typically been analyzed using standard linear regression techniques. Al...

In this study, we examined 11 yr (1998–2009) of water samples collected from Port Hacking coastal monitoring
station 8 km offshore from Sydney, Australia, to assess changes in the microphytoplankton ...
Temporal shift in nutrient input to cold-seep food webs revealed by stable-isotope signatures of associated communities
cold-seep food webs Temporal shift
2014/4/17
A pattern of succession has been demonstrated at Gulf of Mexico cold seeps proceeding from a high-biomass
endemic community dominated by grazers to a diverse community of endemic and nonendemic speci...
How anthropogenic darkening of Lake Apopka induced benthic light limitation and forced the shift from macrophyte to phytoplankton dominance
Lake Apopka induced benthic light limitation forced the shift macrophyte to phytoplankton dominance
2014/4/17
Controversy exists about the historic shift of primary producer community structure (PPCS) in Lake Apopka,a shallow, 125-km2lake in central Florida, U.S.A. The controversial questions are: was a lake-...
Influence of an Offshore Shift in the Gulf Stream on Waters of the South Carolina Continental Shelf
bottom pressure Gulf Stream midrecord shifts South Carolina Continental Shelf
2008/12/23
A 4.3-month-long dataset from moorings on the continental shelf off South Carolina during 1986 showed unusual midrecord shifts in bottom pressure, temperature, stratification, and alongshelf currents....
Directional Response of Wind Waves to a Large Wind Shift
Directional Response Wind Waves Large Wind Shift
2008/7/23
The directional response of a fully arisen sea to a 90° wind shift is studied using a combination of airborne radar and in situ directional wave observations. The observations were made in February 19...
Tropical Pacific 1976–77 Climate Shift in a Linear, Wind-Driven Model
Tropical Pacific Climate Shift Linear Wind-Driven Model
2008/6/13
A number of studies have attempted to explain the cause of decadal variability in the tropical Pacific and explore its possible link to decadal variability in the midlatitude Pacific. To investigate s...
Physiological steady state of phytoplankton in the field? An example based on pigment profile of Emiliania huxleyi (Haptophyta) during a light shift
Physiological steady state phytoplankton pigment profile Emiliania huxleyi a light shift
2014/4/21
A calcifying strain of Emiliania huxleyi was used to study the photoacclimation process during a shift from low (LL) to high (HL) photon flux density (PFD) under nutrient-replete and pH- and [CO2]-con...

denitrification anammox after inflow events central Baltic Sea
2014/4/22
Incubation experiments with 15N-labeled compounds (NO3- and NH4+) were performed during three cruises (2002, 2004, and 2005) to study the loss of inorganic N as dinitrogen gas (N2) via denitrification...
A long-term chlorophyll dataset reveals regime shift in North Sea phytoplankton biomass unconnected to nutrient levels
A long-term chlorophyll dataset reveals regime shift in North Sea phytoplankton biomass unconnected nutrient levels
2014/4/23
During the 1980s, a rapid increase in the Phytoplankton Colour Index (PCI), a semiquantitative visual estimate of algal biomass, was observed in the North Sea as part of a regionwide regime shift. Two...
Does resuspension prevent a shift to a clear state in shallow lakes during reoligotrophication?
