What do paleo-geochemical tracers tell us about the deep ocean circulation during the last ice age?
Paleo-tracers such as carbon 13 and cadmium show that the deep Atlantic was enriched in nutrients during the Last Ice Age. The conventionally accepted interpretation of these higher nutrient levels is that a reduction of the rate of formation of nutrient-depleted Lower North Atlantic Deep Water …

Mixing in the North Atlantic Tracer Release Experiment : observations and numerical simulations of Lagrangian particles and passive tracer
Mixing and stirring of passive tracer and Lagrangian particles in the open ocean was studied through comparison of observations from the North Atlantic Tracer Release Experiment, a numerical model, and existing theory. Based on the observed distribution of tracer during the first six months of the …

Transport of fluid from the boundary of a lake
… from wind forcing on summer stratification. A tracer was injected at the boundary of the lake and surveyed on four separate occasions over a period of three days. The Lake number was less than 10 during the first day of the tracer study. Evidence from three approaches supported the existence of …

Injection and movement of Tritium-³He in the Northeastern Atlantic
… North Atlantic and to use it with transient tracer data to infere rates of ventilation in the subtropcial thermocline. The starting point is the analysis of former studies on box models, transient tracer data and the combination of both. The advantages and pitfalls associated with the tracer …

The placement, fate and effectiveness of granular nematicides in potato beds infested with the potato cyst nematode <i>Globodera pallida</i> (stone)
… using bed cultivation machinery. Fluorescent tracer granule work using a range of granular nematicide incorporation methods suggested that differences exist between the incorporation methods in terms of placement of the fluorescent granules in the planted potato bed. Incorporation of tracer …

Monitoring water and pollutant leaching at an industrial site using geophysics and a vadose zone monitoring system.
… of water flow dynamics and contaminant distribution in the subsurface. However, the retrieval of such information across the vadose zone is challenging, as most field technologies have limited accessibility beyond the first meters of subsoil and industrial environments pose additional …

Some problems in low Reynolds number environmental flows
… in heterogeneous aquifers, the migration of tracers in such flows and the interaction of lava flows with barriers. First, in chapter 2, we examine the injection of fluid of one viscosity and density into a horizontal permeable aquifer initially saturated with a second fluid of different …
