\n\t\t\tNARRAGANSETT, R.I. \u2013 August 1, 2012 \u2013 溏心vlog免费B站 oceanographer David Ullman usually spends his time at the Graduate School of Oceanography studying field observations and numerical models to understand how coastal waters circulate and mix and how those forces affect the health of water bodies.<\/p>\n


\n\tWhen he heard that Rhode Islander Trent Theroux was planning to swim from Point Judith to Block Island this fall to raise $50,000 to help those with spinal cord injuries, Ullman volunteered to use his expertise to help Theroux navigate the strong currents in Block Island Sound.<\/p>\n


\n\t\u201cIt has been a really interesting exercise helping Trent,\u201d said Ullman, a resident of Peace Dale. \u201cI wouldn\u2019t want the guy to get swept out to Portugal.\u201d<\/p>\n


\n\tWhile there is hardly a chance of that happening, Ullman said the strong tidal currents at the northern tip of Block Island could force Theroux to swim several extra miles out of his way or abandon his swim entirely if he didn\u2019t factor in the tides and currents along his route.<\/p>\n


\n\t\u201cTrent says he can swim about two miles per hour, but the currents can be stronger than that at certain times, and if he\u2019s not aware of that, he could be swimming against the current and end up going backwards,\u201d Ullman said.<\/p>\n


\n\tAccording to the 溏心vlog免费B站 oceanographer, Theroux\u2019s first important decision was what date to make the crossing. Ullman suggested making the swim during neap tide, a period when the tidal range \u2013 the difference in elevation between high and low tide — is the least. Since tides are controlled by a combination of the moon and the sun, the largest tidal range occurs during full and new moon phases. Therefore, the best time to make the swim would be on a day half way between full and new moon. Based on this information, Theroux chose to plan his swim for Sept. 8, a date when the tides will be at a minimum.<\/p>\n


\n\tThe direction of tidal currents in Block Island Sound is largely controlled by the eastward and westward flows of water moving into and out of Long Island Sound. With this in mind, Ullman recommended that Theroux begin his swim at Point Judith at the beginning of the flood tide, around 6 a.m., when the currents are starting to flow westward, and he should swim toward a stagnant area about a mile west of the tip of Block Island. By the time he gets there 6-7 hours later, the tide will reverse and Theroux should be able to ride the eastward currents to the island.<\/p>\n


\n\t\u201cIt\u2019s a little tricky at the north tip of Block Island,\u201d noted Ullman. \u201cThere is a very large current there and it\u2019s a treacherous area where the water can be moving at two or two-and-a-half knots. There\u2019s no way he\u2019ll be able to swim against that.\u201d<\/p>\n


\n\tUllman has sent Theroux some tidal current maps and a recommended route. The swimmer\u2019s support team will be able to use GPS to ensure that Theroux remains on course.<\/p>\n


\n\t\u201cI\u2019m looking forward to monitoring his progress and celebrating with him when he completes the swim,\u201d Ullman said.<\/p>\n


\n\t“I am grateful that Dr. Ullman and the GSO staff accepted my request of support for this charity event,\u201d said Theroux, who will swim the backstroke on the entire route. \u201cNavigating the waters of Block Island Sound was of paramount concern for my team. Dr. Ullman’s models clearly identify the correct path to follow during the swim. I thank him for his time and efforts.”<\/p>\n
