Zodiac operations are limited to a two-mile radius of Palmer Station and are allowed when wind speeds are less than 20 knots. A research team sets out in their Zodiac on a routine six-hour sampling run. During the sampling, the wind "freshens" and the team decides to head back to Palmer immediately. The swell and chop of the waves threaten to swamp the boat and make the return slow and difficult. What plans should they have considered "before" setting out? What can they do now to increase a safe return?
It is austral spring. Wind has been moving brash ice in to the nearshore area around the base camp at Palmer Station and hampering data collection. A research team has assessed the conditions and decided to go out on a sampling run. While out on their run, the team is cut off by the ice and cannot return safely to their base. What plans should they have considered "before" setting out? What should they do to ensure their safety now?
After several days of limiting weather conditions, one of the new research teams is finally able to head off to a nearby island to continue gathering data on the effect of UV-B radiation on the growth of plants, mosses and lichens. The combination of low wind and bright sunlight is a welcome break after days of confinement, and they work intently and enthusiastically for several hours. What plans should they have taken in to consideration "before" setting out? What information should they keep in mind as they are working to prevent disaster?
Several teams of researchers are based aboard the Polar Duke . With all deeply involved in what they are doing, the Captain signals an alert to the teams as the Duke comes into heavy waters and starts pitching and rolling. What safety measures are high priority "before" setting out? What safety measures must immediately be deployed? What are the immediate dangers?
