of water have been monitored for many years. Government agencies have
monitored streams, lakes, wetlands, rivers, estuaries, coastal waters,
and reservoirs. The basic reason for monitoring is to fulfill some
requirement. For example, a new treatment plant is constructed and we
want to know if it is in compliance with current regulations. A more
general type of question can deal with regional issues. What is the
quality and condition of the Nation's lakes? What is the quality and
condition of coastal waters and streams in Alaska?
The next 21 pages give a brief introduction to the central ideas of
sampling, starting with simple random sampling, and ending up with
spatially distributed sampling. Software now exists to accomplish
spatially distributed sampling starting from information in Geographic
Information systems. The last page in this series describes two
softare implementations of spatially distributed sampling which existed
where these materials were composed. To go directly to that page,
