Wind forces remained relatively calm throughout the cruise with a minimum of less than one knot to a maximum of 47 knots during transit through the Bering Sea. Higher wind speeds were also observed during periods of snow and the final transit through the Bering Sea (Figure 9). Wind forces less than 10 knots were observed for a total of 192 hours. Periods of snow and fog were intermittent throughout the cruise but did not often obscure visibility (Figure 10). Snow was present, in a light to moderate level, for a total of 96 hours and rain or fog was observed for a total of 21 hours. The Beaufort sea state ranged from levels 1 through 8 but generally remained between a level 3 and level 6. Speed ≤10 knots 11-20 knots ≥21 knots UME04085 R.V Marcus G.
