  2. Hydrographic survey - Wikipedia

    en.wikipedia.org/wiki/Hydrographic_survey

    Although the accuracy of crowd-sourced surveying can rarely reach the standards of traditional methods, the algorithms used rely on a high data density to produce final results that are more accurate than single measurements. A comparison of crowd-sourced surveys with multibeam surveys indicates an accuracy of crowd-sourced surveys of around ...

  3. Eddy covariance - Wikipedia

    en.wikipedia.org/wiki/Eddy_covariance

    Oxygen fluxes are extracted from raw measurements largely following the same principles as used in the atmosphere, and they are typically used as a proxy for carbon exchange, which is important for local and global carbon budgets. For most benthic ecosystems, eddy correlation is the most accurate technique for measuring in-situ fluxes. The ...

  4. Indirect calorimetry - Wikipedia

    en.wikipedia.org/wiki/Indirect_calorimetry

    Face mask (breath by breath): Indirect calorimetry tests are also often performed with a face mask, which is used to convey exhaled and inhaled gas through a turbine flowmeter able to measure the patient's breath by breath minute ventilation, at the same time a sample of gas is conveyed to the analyser and VO 2 and VCO 2 are measured and ...

  5. Well test (oil and gas) - Wikipedia

    en.wikipedia.org/wiki/Well_test_(oil_and_gas)

    The test will also provide information about the state of the particular well used to collect data. The overall objective is identifying the reservoir's capacity to produce hydrocarbons, such as oil, natural gas and condensate. Data gathered during the test period includes volumetric flow rate and pressure observed in the

  6. Hydrograph - Wikipedia

    en.wikipedia.org/wiki/Hydrograph

    A stream hydrograph is commonly determining the influence of different hydrologic processes on discharge from the subject catchment. Because the timing, magnitude, and duration of groundwater return flow differs so greatly from that of direct runoff, separating and understanding the influence of these distinct processes is key to analyzing and simulating the likely hydrologic effects of ...

  7. Gas exchange - Wikipedia

    en.wikipedia.org/wiki/Gas_exchange

    Gas exchange is the physical process by which gases move passively by diffusion across a surface. For example, this surface might be the air/water interface of a water body, the surface of a gas bubble in a liquid, a gas-permeable membrane, or a biological membrane that forms the boundary between an organism and its extracellular environment.

    What Causes Good Greens To Go Bad. Unlike what the post suggests, leafy greens aren’t a major source of ethylene.But they are sensitive to produce that emits the gas. That’s why you should ...

  9. Tracer use in the oil industry - Wikipedia

    en.wikipedia.org/wiki/Tracer_use_in_the_oil_industry

    In interwell tests, the tracer is injected at one well along with the carrier fluid (water in a waterflood or gas in a gasflood) and detected at a producing well after some period of time, which can be anything from days to years.
