🔍 Key Concepts

• World Meteorological Organization (WMO) sea ice concentration scale and its terms like open drift, close pack, very close pack, and compact ice • How ice concentration in tenths relates to how much open water is still visible • The difference between moderate, close, and very close pack ice in operational ice navigation

💭 Think About

• Think about what the word "close" suggests about how much open water is left between the ice floes. • Compare the options and ask yourself: in which range would ship maneuvering space start to become seriously restricted, but not yet at the absolute maximum concentration? • Consider which ranges are more likely to describe scattered ice versus nearly continuous ice cover.

✅ Before You Answer

• Verify which range is used for very close pack / compact ice (almost no open water) and then step down one level to find "close pack." • Check that the range you select leaves some room for navigation but would still be considered hazardous and restrictive for most vessels. • Eliminate any ranges that clearly describe ice that is either too sparse (lots of open water) or essentially solid with almost no gaps.
