this region;
- Developments of underice sampling
systems for biological studies in the
Arctic and use on field programs
continued;
- Current meters were moored and field
surveys completed to monitor the water
exchange between Baffin Bay and the
Northwest Atlantic as part of a regional
ice modelling experiment;
- For the third year, ice beacons were
placed on the Labrador ice sheet to
track the southward advection as part of
the sea ice climatology and modelling
for the Hibernia area;
- A CODE (Centre Of Disciplinary
Expertise) in marine contaminants and
toxicology was established to deal with
sensitive habitat issues resulting from
adverse chemical changes;
- Work continued on the the development
of a Climate Research Strategy for
the Department to include various
major international programs, departmental
interests and collaboration
throughout the scientific community;
- Studies were completed on the influence
of mean circulation and horizontal
dispersion on the survival and recruitment
success of the Browns Bank
gadoid stocks in collaboration with
Biological Sciences Branch;
- The Branch participated in the development
of a shipboard handling, refueling,
and recovery system for the DOLPHIN
semisubmersible, remotely operated
vehicle, in collaboration with the
Hydrography Branch;
- Studies were undertaken through the
use of MFO induction measurements to
observe the effects of petroleum hydrocarbons
on flounder fish as a sample
species;
- Stable carbon isotope analysis was
applied to the study of growth rates in
various marine organisms as part of
stock management data in conjunction
with Biological Sciences Branch;
- The assessment of the general oceanography
of the Arctic Ocean continued
based upon carbon and nutrient budgets
and participation in an international
cruise in the Arctic Ocean; and
- Studies continued on the effects of acid
rain on salmon stocks in Nova Scotia
rivers and the possible mitigating effects

features during successive satellite overpasses (open arrows), and by monitoring positions of satellitereporting
