Countermeasures
In ice concentrations down to six tenths, in situ burning of oil in conjunction with tracking oiled ice is
recommended. In open water conditions in offshore and nearshore areas, containment for recovery or
burning is recommended. Dispersant application to protect waterfowl should be considered in the offshore
and nearshore waters.
Although no current information is available for the many inlets and fjords on this map, the tidal range (3 to 4
m), the geometry of the inlets, and the high reported tidal velocities in a few fjords to the north, suggest that
exclusion booming (applicable in currents up to 0.4 m/s to 0.75 knots) of these features would not likely be
successful, and is thus not recommended. If local knowledge suggests areas where tidal velocities are less
than a knot, exclusion booming could be attempted across fjords or inlets that are up to a kilometre or less in
width. Alternatively, diversion booming could be attempted to protect sensitive areas, but even this will not
likely succeed in currents exceeding 1.5 m/s (3 knots), due to the excessive lengths of boom and the number
of intermediate anchors required to maintain the required angle of the boom to the current. The requirement
to constantly change boom angle with changing tidal stream direction would further complicate diversion
booming operations.
Offshore countermeasures represent the only practical method of protecting most shoreline areas.
Nearshore protective booming utilising 1000 m of boom could protect the sensitive bay to the northeast of
Paamiut (Frederikshåb), providing currents are in an acceptable range. The harbour of Paamiut itself could
be protected with 500 m of boom deployed across the various channels, again providing currents are
sufficiently weak. The inner reaches of Tininnertooq could be protected with 1000 m of boom, providing
areas of sufficiently low current can be identified.
Shorelines shown on this map are predominantly exposed rock which may not require active cleaning efforts
unless heavily contaminated with heavy oils.
Two small sections of the coast are designated as saltmarsh or tidal flat (at the head of Tininnertooq) and
barrier beach (west and northwest of Nunasarnaq) and may include sand beaches with protected or semiprotected coastal exposure; if oiled, these areas may require cleaning using sediment removal techniques,
along with the temporary stockpiling and subsequent removal for disposal of collected materials. In each of
these areas, marine access and beach trafficability are unknown, necessitating site surveys at the time of
the cleanup.

Access
The nearshore waters in this area are largely uncharted and caution should be exercised. In general, the
waters offshore, nearshore, and within the fjords are deep, however, uncharted dangers may exist.
The prevailing current is ½ knot, setting to the NW in waters along the coast.
Several anchorages and berths are available at the town of Paamiut (Frederikshåb). A berth suitable for
vessels to 100 m length and 6 m draft is located within the harbour. Facilities in the harbour include mobile
cranes, boatyard, garage, and hospital, and water and fuel are available. There are also anchorages E of
Skarvø in 18 to 22 m with poor holding and exposure to SW wind and swells, and close SE of Kofoeds Båke
in 20 m. Access to Paamiut can be difficult due to ice: between April and August pack ice and bergs from the
north may be present. Locally-formed ice to a thickness of 47 cm may also be present from December to
March although this frequently breaks up and the harbour is regarded as navigable year-round. The berthing
and facilities at Paamiut make it a candidate as potential staging site.
At the entrance to Qassit fjord, anchorage is available at Avigait in 19 m, and at Niaqornaq in 19 m, both
appear to have good shelter.
To the north of Paamiut and Qassit fjord, caution is advised due to the many islets and rocks; a distance of 8
miles west of the mainland is advised in the vicinity of Frederikshåb Isblink.
Anchorage for small vessels is available in the inlet of the east side of the south end of Qeqertarsuaq
(Nordre Storø), the large island at the entrance to Nerutussoq, in the bay sheltered by islets on the west side
of the south end.
In the group of islands just north of Qassit fjord, an anchorage is indicated close north of the island of
Majorssuit, no depths reported.
Shorelines in this area are predominantly rock allowing little opportunity for marine access. Pocket beaches
near Frederikshåb Isblink may allow landings in good weather.
There are no existing airports on this or adjoining maps, although one is reported to be planned for Paamiut
Safe havens
A potential safe haven for vessel lightering operations is the unnamed bay 10 km north of Paamiut
(Frederikshåb). It is in an area of moderate sensitivity. If local knowledge suggests that tidal currents are
sufficiently low, booms could be deployed across the inner portions of the bay to contain any further
release of oil.
