The phrase
"mass balance" refers to keeping track of the amount of something going in and out of a system. It is used to ensure that the total amount of a substance or material remains the same or is accounted for accurately. This can be applied in various fields like environmental science, engineering, or even in our daily lives to monitor inputs and outputs of different substances.
Full definition
Each measurement location for 10, 20, 40 and 80 measurement point networks was specifically selected as the best representative of the average
mass balance of the surrounding region.
In fact, there are now well over 150 individual assessments of ice
sheet mass balance based on measurements acquired by at least 15 different satellite missions.
The typical density and total number of measurements currently used in
annual mass balance measurement is indicated in Table 1.
The glacier has since been in a
negative mass balance state, which may result in a retreat if the current trends continue.
The annual glacier
mass balance record below indicates that the response of annual balance is quite similar for each glacier.
In order to achieve optimal accuracy, it is apparent that multiple measurements are needed in each
specific mass balance zone of the glacier.
These measurements have been made in concert with energy balance to identify the cause of the rapid retreat and
mass balance loss of these tropical glaciers.
I am concerned with how changes in climate affect
glacial mass balance and the physical and chemical properties of snow.
Climate change has led to an observed increase in surface melting, surface accumulation, increased discharge and
overall mass balance losses.
Each network of points was chosen to provide the most even distribution possible of measurements across each glacier, given the
known mass balance pattern.
It makes sense to use «carbon» when an
elemental mass balance is being derived from the conversion of different carbon species.
The four main methods are the emission factor - based method,
mass balance method, predictive emissions monitoring systems, and continuous emissions monitoring systems.
There is growing emphasis on verifying organic integrity through in - depth review of audit trail systems, and
mass balance exercises.
The study of ice sheet
mass balance underwent two major advances, one during the early 1990s, and again early in the 2000s.
The aim of this study was to illustrate the minimum number of measurements needed to determine annual
mass balance accurately from field measurements alone.
The latter portion of the study period 1995 - 2000 has been more favorable but very inconsistent and can not yet be identified as a period of more
favorable mass balance.
A glacier's
mass balance hence, its response to climate is complicated by its geographic characteristics.
If we look at more recent work, which examines the changes in volume discharge and
surface mass balance, we see the greatest discharge changes and surface loss are in the southeast.
In addition to adding mass to a glacier, precipitation has an indirect effect on
glacier mass balance by changing the amount of sunlight the glacier absorbs.
The consistency of the cumulative balance trends further indicates the glaciers
mass balance record is dominated by large scale regional to global climate change.
A series of benchmark glaciers around the world were chosen where
annual mass balance would be monitored.
However,
mass balance observations are needed for estimating the contribution of glacier melt to sea level rise, so are discussed further in Chapter 11.
