Mapping the spatial variability of plankton metabolism using nitrate and oxygen sensors on an autonomous underwater vehicle
Mapping the spatial metabolism using nitrate
2009/4/18
It is now possible to make highly resolved vertical (,1 m) and horizontal (3 m at constant depth and ,400 m
when undulating from surface to 100 m) measurements of nitrate concentration in the upper o...
Spatial and temporal variability of prairie lake hydrology as revealed using stable isotopes of hydrogen and oxygen
Spatial temporal variability hydrogen and oxygen
2009/4/17
Evaporation and groundwater fluxes are thought to regulate hydrologic variability in lakes of the northern
Great Plains, but little is known of how the relative importance of these processes may vary...
Spatial and temporal variability of solar ultraviolet exposure of coral assemblages in the Florida Keys: Importance of colored dissolved organic matter
Spatial and temporal variability solar ultraviolet exposure
2008/4/21
Solar ultraviolet (UV) radiation can have deleterious effects on coral assemblages in tropical and subtropical
marine environments, but little information is available on UV penetration into ocean wa...

Spatial variations plankton metabolic rates
2008/4/21
Plankton metabolic rates, such as rates of gross, net community production and community respiration, were
measured in the surface waters using triple oxygen isotopes and O2

Macro- to fine-scale spatial and temporal distributions and dynamics of phytoplankton and their environmental driving forces in a small montane lake in southern California, USA
Macro- to fine-scale spatial temporal distributions
2008/4/18
A wireless network of buoys, two autonomous robotic boats, and an autonomous tethered vertical profiling
system were used to characterize phytoplankton dynamics and spatiotemporal changes in chemical...
Spatial analysis of ice phenology trends across the Laurentian Great Lakes region during a recent warming period
ice phenology trends the Laurentian Great Lakes
2007/4/22
We examined spatial patterns of trends in ice phenology and duration for 65 waterbodies across the Great
Lakes region (Minnesota, Wisconsin, Michigan, Ontario, and New York) during a recent period of...
Controls on spatial and temporal variation of nutrient uptake in three Michigan headwater streams
Controls on spatial nutrient uptake
2007/4/22
We measured whole-stream uptake of ammonium (NHz

Field data and numerical simulations were used to investigate the effects of basin shape, continuous stratification,
and rotation on the three-dimensional structure of the dominant natural basi...
Spatial and temporal variability in factors affecting mesozooplankton dynamics in Chesapeake Bay: Evidence from biomass size spectra
Spatial and temporal variability factors affecting mesozooplankton dynamics
2006/4/23
Zooplankton biomass in Chesapeake Bay was estimated with an optical plankton counter mounted on a towed
body (Scanfish). Normalized zooplankton biomass size spectra were calculated for three Ba...

Process of chemistry optics micrometers non-biological water nutrients and phytoplankton clastic sediment
2004/6/29
The physical, biological, chemical, and optical processes of the ocean operate on a wide variety of spatial and temporal scales, from seconds to decades and from micrometers to thousands of kilometers...
Atmospheric deposition of inorganic phosphorus in the Levantine Basin, eastern Mediterranean: Spatial and temporal variability and its role in seawater productivity
Levantine Basin eastern Mediterranean
2003/5/21
Total and dissolved inorganic phosphorus (IP) was measured in both rainwater and aerosol samples collected
from two remote coastal areas: on the island of Crete (Greece) and at Erdemli (Turkey). Part...
