🔍 Key Concepts

• Ice detection indicators commonly used by mariners in high latitudes • The relationship between water temperature and the freezing point of saltwater vs. freshwater • Traditional signs of pack ice such as sky color (ice blink vs. water sky) and wildlife presence

💭 Think About

• Which of these choices is least reliable or not directly caused by nearby sea ice? • Think about how seawater salinity affects the freezing point—does ocean water usually freeze right at 32°F? • Which visual sky effect is actually associated with ice reflecting light, and which might indicate open water or other conditions instead?

✅ Before You Answer

• Identify which indicators are commonly taught in seamanship/ice navigation as reliable signs of nearby ice • Consider typical freezing point of seawater (about 28–29°F) rather than pure water at 32°F • Check which sky appearance is linked to ice blink (lighter/whitish) and which is more typical of open water (darker) conditions
