actively involved in a variety of assess-

1998. These have provided models and
budgets in estuarine and coastal seas of
carbon, nitrogen and phosphorus fluxes
and net system metabolism, developed by
an expanding group of regional experts. A
common methodology (LOICZ Reports
and Studies Volume 5) was applied to
assist with comparison between sites as
local to global scales. Results are
published in LOICZ Reports & Studies
