The island moved a few km on the first trip; for most of the time, however, it was stationary. On the second trip, movement in a northeast direction was more frequent and substantive. On both trips, the island remained over the shelf in water depths of less than 300 m just north of Axel Heiberg Island. In June 1987, the island was also stationary for most of the time, although some large leads opened up around the island near the middle of the month. Movement of the island during 1986 and 1987 is shown in Figure 2.1. In August, sampling was from the edge of the island and sampling in May, 1986 and June 1987 was carried out at a site just off the island on an area of 1.4 m thick first year ice. A large diameter hole (1.5 m) was made using a portable hot water ice melter. The melter uses a 450,000 BTU oil burner to heat water which is circulated through a heating chamber then pumped o a perforated copper ring. Melt water is pumped back through the heating chamber. The design is based on a unit developed by the Frozen Sea Research Group at the Institute of Ocean Sciences in Patricia Bay, B.C. The hole was melted about 50 m from the edge of the island. A 4.6 m x 2.4 m Hansen Weatherport (R) insulated tent was erected over the hole. In August, a tent was erected as a heated shelter close to the ice edge. One tent was left on the island between trips and served as a storage shed for equipment. A Coleman oil heater was used to heat the tent in May 1986, an electric heater was used in August and a propane heater in June 1987. The main ice hole was used principally for plankton collections. Prior to net tows, CTD and bottle casts were made to collect samples for nutrients and salinity. After plankton sampling was complete, some bottom grabs were also taken from the hole. A number of smaller diameter holes (0.6 m) were melted near the tent away from the island to obtain ice cores. One of these holes was used exclusively to deploy the in-situ samplers, while another hole was used to deploy baited traps and a grab sampler.
