We're crossing Drake Passage into the Southern Ocean on our way to Antarctica and these conditions. Usually a 2 day journey, although quicker in good weather, the Drake Passage can range from incredibly calm (imagine being gently lulled to sleep) to, well, a lot worse. Their mean locations, indicated in Figure 1, were estimated by iden- tifying dynamic height gradient maxima in Gordon et al.'s [1982] atlas data and smoothed using a biharmonic spline. Monday 11/29. Passengers often dread it because its rough seas can dislodge furniture, footsteps and even the most hardened stomach from its moorings. The Drake Passage is the stuff of legends, and crossing it is an experience some passengers on Antarctica cruises look forward to the most. (Reference Cusack, Naveira Garabato, Smeed and Girton 2017) found evidence of enhanced vertical velocities throughout the water column all the way to the top 500 m of the ocean above a ridge of 2500 m depth in the Drake Passage, suggesting interaction between the large wave . WAVE HEIGHTS.The frequency pattern of wave heights equal to or greater than 12 feet is very similar to that of The Drake Passage is known for temperatures between 26 to 41 degrees Fahrenheit, lower than in the Atlantic and Pacific, and can see waves of up to 50 feet in height. This produces a wind tunnel effect, causing phenomenal waves and tidal surges. (gentle rolling waves 4 to 5 feet in height) as we sailed toward the South Shetland Islands. The Drake Passage is a fierce body of water that is around the Cape Horn and the South . Drake Passage, deep waterway, 600 miles (1,000 km) wide, connecting the Atlantic and Pacific oceans between Cape Horn (the southernmost point of South America) and the South Shetland Islands, situated about 100 miles (160 km) north of the Antarctic Peninsula. However, for lee waves generated by abyssal hills at the bottom of the ocean, Fr DU=.ND/is very small and offers little information about the system. In Drake Passage, ageostrophic motions appear to be dominated by inertia-gravity waves and account for about half of the near-surface kinetic energy at scales between 10 and 40 km. Dates: none. Seasoned travelers say the Drake Passage has two states: the 'Drake Lake' or the 'Drake Shake'.
