To understand the population dynamics of key
species in terms of their coupling to the physical environment and in terms
of their predators and prey. |
|
|
|
|
To be able to predict changes in the
distribution and abundance of target species as a result of changes in
their physical and biotic environment as well as to anticipate how their
populations might respond to climate change. |

Distributed data - client/server system |
|
Open access - read only |
|
Quality control on-going |
|
Emphasis on access to data and information as
quickly as possible |
|
|
|
|
|
|
Data sets being collected are most worthwhile in
the context of all the other data sets being collected |
|
Investigators must respect the ownership of the
data and should request permission to use data. Collaboration encouraged. |
|
|
|
|
|
|
The data object receives requests and responds
with data; and a server connects
applications to objects. |
