Vertical fluxes in the upper ocean
… understanding of submesoscale vertical tracer fluxes and their influence on carbon cycling. Unlike buoyancy, vertical transport of biogeochemical tracers can occur both due to the movement of isopycnals and due to motion along sloping isopycnals. We decompose the vertical velocity below the …

Antarctic climate: ocean fluxes and variability
… Southern Ocean circulation and the balance of fluxes around the<br/>Antarctic Circumpolar current.<br/><br/>A historical data set in the region of Drake Passage is examined to study the large-scale<br/>water mass variability between 1926-2005. The water mass properties of the …

Nutrient fluxes and soil microbial processes
… and microbial biomass (c) nutrient input fluxes from throughfall and litterfall (d) foliar nutrient status. This investigation was carried out in south-eastern Belgium at a site converted in 1998 to a mixed deciduous stand, after two spruce generations. Plantations of common alder (Alnus …

Tropical cyclone momentum and energy fluxes
… to determine angular momentum and enthalpy fluxes at the sea surface. These results show that the intensification of a hurricane is very sensitive to the values of the coefficients defined in these formulae (Emanuel, 1995). Using these formulae allows the model to make bulk estimates of …

Fluxes of Sporadic Meteoroids from Optical Measurements
… of the eta Aquariid meteor shower. Eta Aquariid fluxes yielded ZHRs of 14.3 ± 4.5 meteors hr'1and 65 ± 10 meteors hr'1 on the measured nights in agreement with literature values (Rendtel, 1997). The mass index of sporadic meteors was s = 2.14 ± 0.12 and the speed distributions were found to be in …

On the predictability of land surface fluxes
… to uncertainty in climate projections. Fluxes of energy, momentum, water and carbon between the land surface and the atmosphere provide important feedbacks in the climate system. Land surface models (LSMs) have been a key tool in understanding land surface fluxes, the processes that …

Trace Greenhouse Gas Fluxes in Upland Forests
… the majority of studies describing tree stem fluxes of methane (CH₄) and nitrous oxide (N₂O) have focused on wetland ecosystems. Tree stem fluxes of GHGs on free-draining soils are understudied, but they are assumed to be a source of CH₄ and a weak source of N₂O. The work presented in this …

Spectral Computed Tomography at High Photon Fluxes
… of Medipix2 MXR detectors under high photon fluxes, which do not meet this requirement. At first, it is shown that the critical photon flux, at which the detector’s linearity breaks down, can be shifted towards higher values by increasing the IKrum current in the charge sensitive …

Free convection and turbulent fluxes over complex terrain
… Black Forest, southwestern Germany. Turbulent fluxes were calculated with the eddy-covariance (EC) method and were used to detect FCCs with the help of a stability parameter. The flux measurements were further combined with ABL profiling measurements (Sodar/RASS) and a large-eddy simulation …

Latent heat fluxes through nano-engineered porous materials
Micro- and nano-scale truss architectures provide mechanical strength, light weight, and breatheability in polymer barriers. Liquid evaporation and transport of resulting vapor through truss voids (pores) cools surfaces covered by the barriers, suggesting the possibility for simultaneous protection …

Sea Spray-Mediated Fluxes at Extreme Wind Speeds
… sea spray plays a critical role in mediating the fluxes which control tropical cyclone intensity. The first part of this thesis reviews and synthesizes results from the literature on parameterizations of air-sea enthalpy and momentum fluxes in tropical cyclones, with an emphasis on work that …

Fluxes, dynamics and chemistry of particulates in the ocean
… to yield quantitative data of particulate fluxes have been deployed and successfully recovered on four moorings in the deep sea. The traps were designed after extensive calibration of different shapes of containers. Further intercalibration of trap design was made in field experiments over …
