Projections of the movement of oil slicks and their impact location along the shorelines of Texas, Louisiana, Mississippi, Alabama and Florida were determined from three potential deepwater port sites. Average monthly wind speeds and directions and average monthly current patterns were used for predicting the oil slick movement. Seasonal patterns of oil slick drift and probable areas of impact along the shoreline were indicated. (Author).

Predictions of the movement of oil slicks and their impact locations along the shoreline of New Jersey and Delaware were determined for two potential deepwater ports and two potential drilling sites. A hydrodynamical-numerical model for the New York Bight area was coupled with a wind generating model to produce temporal patterns of concentration of oil. Shoreline impact determinations were made for the four spill sites for the average winter storm conditions and average summer high pressure systems generated by the models.

This is a reference document on oceanography, meteorology, ice and climatology. The oceanography section contains information for circulation, tides, riverine input, ice conditions, storm surges and bathymetry of the Alaskan Beaufort Sea. From review of information on meteorology, climate, ice conditions, and oceanography, maps have been generated showing circulation in two typical wind conditions: ENE wind at 10 knots and NW storm wind at 30 knots. These maps show tides, storm surges, bathymetry and river discharges as well as charts of mean ice drift over time. The meteorology section contains information on winds, storm surges and waves. Included is a rapid manual forecast system for estimating the height of a storm surge. The ice section gives information on the ice zones, including the annual ice cycle within the nearshore area, the freezing and breakup of nearshore ice, and the movement of the pack ice. The climatology section includes information on the arctic climate, temperature information (including wind chill charts), visibility, and precipitation.

During the summers of 1979 and 1980 aerial photographs of the land fast ice north of Prudhoe Bay, Alaska, were taken. These photographs, covering two-week periods, highlight the decay and break-up of the land fast ice sheet. During the period of photography, wind speed, wind direction, barometric pressure, and tidal height measurements were recorded continuously. Several larger ice floes were 'tagged' with colored plywood markers during 1979. Both these marked flows and other distinctively shaped floes were tracked on the photographic surveys to determine the effect the wind had on their movement. Within the barrier islands, average ice floe velocities as a percentage of wind speed exceeded the 3.5% figure 'normally' found in the literature. North of these islands average ice floe velocities as a percentage of wind speed were less than the 3.5% value. In addition to the flow drift calculations the photographs provide information on melt pool formation and a comparison of the decay and breakup processes between the 1979 and 1980 seasons. The decay and breakup process appears to be triggered by strong wind events in early July. (Author).

Surface drifters were released in the Beaufort Sea near Prudhoe Bay, Alaska for two years (1979-82). The releases were made under the shorefast ice just prior to summer breakup of the ice and in leads in the pack ice. The drifter recoveries indicate that the winds play a significant role in the surface circulation during the open water season. A significant number of drifters beached 'onshore' of their release sites. 'Preferred' beaching areas are identified from the drifter recoveries. All these results indicate the strong possibility that oil released offshore in the Beaufort Sea will impact the North Alaska Coast.
